  • COVID-19 and financial toxicity in patients with renal cell carcinoma
    • Abstract: Purpose To ascertain renal cell carcinoma (RCC) financial toxicity on COVID-19 during the COVID-19 crisis as patients are struggling with therapeutic and financial implications. Methods An online survey was conducted from March 22 to March 25, 2020. It included baseline demographic, clinicopathologic, treatment-related information, anxiety levels related to COVID-19, questions related to financial concerns about COVID-19 as well as the validated 11-item COST measure. Results Five-hundred-and-thirty-nine patients (39%:58% male:female) from 14 countries responded. 23% of the patients did not feel in control of their financial situation but 8% reported being very satisfied with their finances. The median COST score was 21.5 (range 1–44). Metastatic patients who have not started systemic therapy had a COST score (19.8 range 2–41) versus patients on oral systemic therapy had a COST score (23.9 range 4–44). Patients in follow-up after surgery had a median COST score at 20.8 (range 1–40). A low COST scores correlated (p < 0.001) were female gender (r = 0.108), younger age (r = 0.210), urban living situation (r = 0.68), a lower educational level (r = 0.155), lower income (r = 0.165), higher anxiety about acquiring COVID-19 (r = 0.198), having metastatic disease (r = 0.073) and a higher distress score about cancer progression (r = 0.224). Conclusion Our data highlight severe financial impact of COVID-19. Acknowledging financial hardship and thorough counseling of cancer patients should be part of the conversation during the pandemic. Treatment and surveillance of RCC patients might have to be adjusted to contemplate financial and medical needs.

  • Prognostic value of pretreatment inflammatory markers in variant
           histologies of the bladder: is inflammation linked to survival after
           radical cystectomy'
    • Abstract: Purpose To investigate differences in standard preoperative inflammatory markers in patients with urothelial carcinoma (UC) and variant histologies undergoing radical cystectomy (RC) and determine its impact on survival. Methods Patients undergoing RC at an academic high-volume center were retrospectively analyzed. Preoperatively taken CRP, leukocytes, hemoglobin (Hb), and thrombocytes were analyzed as routine inflammatory biomarkers. Log-rank tests and Kruskal–Wallis analysis were used to calculate for differences in survival and in blood levels of biomarkers. Results 886 patients with complete follow-up and UC or variant histology underwent RC at our institution between 2004 and 2019. Although variant histology presents with significantly higher t stage than UC, cancer-specific survival (CSS) of UC (1-year-CSS: 93%) is not significantly different to variant histology of UC with squamous differentiation (UCSD, 1-year-CSS: 81%), squamous cell carcinoma (SCC, 1-year-CSS: 82%), and adenocarcinoma (AC, 1-year-CSS: 81%). In UC, alterations in all biomarkers except leukocytes beyond routine cut-off values were associated with poor survival (p < 0.01), whereas Hb beyond cut-off values are associated with poor prognosis in SCC (p < 0.05). CRP levels are significantly elevated in UCSD and SCC at time of surgery compared to UC (p < 0.05). Conclusion Inflammatory biomarkers reveal distinctive patterns across UC and variant histologies of bladder cancer. As inflammation might play an important role in cancer progression, further research is warranted to understand those molecular mechanisms and their potential therapeutic impact in variant histology of bladder cancer.

  • Detection of prostate cancer with 18 F-DCFPyL PET/CT compared to final
           histopathology of radical prostatectomy specimens: is PSMA-targeted biopsy
           feasible' The DeTeCT trial
    • Abstract: Purpose In primary prostate cancer (PCa) patients, accurate staging and histologic grading are crucial to guide treatment decisions. 18F-DCFPyL (PSMA)-PET/CT has been successfully introduced for (re)staging PCa, showing high accuracy to localise PCa in lymph nodes and/or osseous structures. The diagnostic performance of 18F-DCFPyL-PET/CT in localizing primary PCa within the prostate gland was assessed, allowing for PSMA-guided targeted-prostate biopsy. Methods Thirty patients with intermediate-/high-risk primary PCa were prospectively enrolled between May 2018 and May 2019 and underwent 18F-DCFPyL-PET/CT prior to robot-assisted radical prostatectomy (RARP). Two experienced and blinded nuclear medicine physicians assessed tumour localisation within the prostate gland on PET/CT, using a 12-segment mapping model of the prostate. The same model was used by a uro-pathologist for the RARP specimens. Based on PET/CT imaging, a potential biopsy recommendation was given per patient, based on the size and PET-intensity of the suspected PCa localisations. The biopsy recommendation was correlated to final histopathology in the RARP specimen. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for clinically significant PCa (csPCa, Gleason score ≥ 3 + 4 = 7) were assessed. Results The segments recommended for potential targeted biopsy harboured csPCA in 28/30 patients (93%), and covered the highest Gleason score PCa segment in 26/30 patient (87%). Overall, 122 of 420 segments (29.0%) contained csPCa at final histopathological examination. Sensitivity, specificity, PPV and NPV for csPCa per segment using 18F-DCFPyL-PET/CT were 61.4%, 88.3%, 68.1% and 84.8%, respectively. Conclusions When comparing the PCa-localisation on 18F-DCFPyL-PET/CT with the RARP specimens, an accurate per-patient detection (93%) and localisation of csPCa was found. Thus, 18F-DCFPyL-PET/CT potentially allows for accurate PSMA-targeted biopsy.

  • Innovative standardized reporting template for prostate mpMRI improves
           clarity and confidence in the report
    • Abstract: Purpose The goal of the current study was to evaluate the effect of a standardized prostate mpMRI reporting template on urologists’ understanding and confidence in counselling a patient on the results of the MRI. To do this we performed a survey study to assess the understanding and confidence of urologists reviewing reports prior to (pre) and after (post) adoption of a standardized mpMRI template. Methods Six urologists reviewed ten pre- and post- mpMRI templated reports and completed a survey to assess the clarity of key elements and the confidence in counseling the patient. The urologists were blinded to the study objective. Nonparametric constrained permutation test for significance was performed to compare the results prior to and after implementation of the template. Results 29 pre- and 30 post-template mpMRI reports were reviewed. The average score for the post-template reports was significantly higher (10.7 ± 0.6 vs 7.5 ± 2.7 [ p< 0.001]) regardless of the reviewer. Urologists were also overall more confident in counselling patients when the standardized mpMRI reporting template had been used. Conclusion Implementation of a standardized template for reporting of prostate mpMRI findings resulted in improved clarity and confidence in counselling patients. Radiologists should consider implementing a standardized reporting template to improve clinicians’ understanding and confidence of the report.

  • Health-related quality of life in Japanese low-risk prostate cancer
           patients choosing active surveillance: 3-year follow-up from PRIAS-JAPAN
    • Abstract: Purpose To evaluate the health-related quality of life (HRQoL) of Japanese men on active surveillance (AS) in the Prostate cancer Research International Active Surveillance study in Japan (PRIAS-JAPAN). Methods Participants were included in the PRIAS-JAPAN HRQoL study between January 2010 and March 2016. Their general HRQoL was assessed using a validated Japanese version of the Short-Form 8 Health Survey (SF-8) at enrolment and annually thereafter until discontinuation of AS. The SF-8 mental component summary (MCS) and physical component summary (PCS) of men on AS were compared with scores of the general population (norm-based score [NBS]: 50) and MCS and PCS scores for men following AS were analysed over time. We tested whether MCS and PCS scores over time explained discontinuation of AS. Results Five hundred and twenty-five patients enrolled, and the median age at baseline was 68 years. At enrolment and after 1-, 2-, and 3-year follow-ups, the PCS and MCS scores were significantly higher than the NBS of the general Japanese population except for the median PCS at 3 years. We found that age at diagnosis and time on AS negatively affected the PCS score of men on AS, while every additional year on AS led to a 0.27 point increase in MCS scores. Neither PCS nor MCS were predictors for discontinuation of AS. Conclusion Japanese men following an AS strategy for 3 years reported better HRQoL compared with the general population, indicating that monitoring Japanese low-risk prostate cancer patients can be an effective treatment strategy.

  • A uro-protective agent with restorative actions on urethral and striated
           muscle morphology
    • Abstract: Purpose Aging increases oxidative stress, which can have delirious effects on smooth and striated muscle resulting in bladder dysfunction. Consequently, in women aged over 60 years, urinary incontinence (UI) is a prevalent health problem. Despite the prevalence and consequences, UI continues to be undertreated simply because there are few therapeutic options. Methods Here we investigated whether 8-aminoguanine (8-AG), a purine nucleoside phosphorylase (PNPase inhibitor), would restore urethra and external sphincter (EUS) muscle morphology in the aged rat. Aged (> 25 months) female Fischer 344 rats were randomized to oral treatment with 8-AG (6 weeks) or placebo, and the urethra and EUS were evaluated by electron microscopy and protein expression (western immunoblotting). Results Aging was associated with mitochondrial degeneration in smooth and striated muscle cells as compared to young rats. We also observed a significant increase in biomarkers such as PARP, a downstream activator of oxidative/nitrosative stress. Treatment of aged rats with 8-AG normalized all abnormalities to that of a younger state. Conclusions 8-AG, a potent inhibitor of PNPase, reverses age-related lower urinary tract morphological and biochemical changes. Our observations support the concept that 8-AG will reverse age-induced lower urinary tract disorders such as UI. These initial findings could have therapeutic implications for the prevention and treatment of age-related UI.

  • Contemporary use of phytotherapy in patients with lower urinary tract
           symptoms due to benign prostatic hyperplasia: results from the EVOLUTION
           European registry
    • Abstract: Background To use the European Association of Urology Research Foundation (EAURF) registry data to determine the proportion of contemporary Lower Urinary Tract Symptoms associated with Benign Prostatic Enlargement (LUTS/BPE) patients prescribed phytotherapy, and to determine their subjective quality of life and clinical progression responses. Methods This was a prospective multicenter multinational observational registry study, conducted over 2 years. Men ≥ 50 years seeking LUTS/BPE were divided at baseline into two cohorts, presently/recently untreated patients (PUP) commencing pharmacotherapy at baseline and presently/recently treated patients (c-PTP) continuing previously received pharmacotherapy, with 24-month follow-up (FU). Results Overall, 2175 patients were enrolled with 1838 analyzed. Of the PUP cohort (n = 575), 92 (16%) received phytotherapy and 65 (71%, n = 65/92) completed 24-month FU, with France prescribing 34% (n = 30/89) the highest proportion of phytotherapy among all LUTS/BPE medications. In the c-PTP group (n = 1263), only 69 (5%) patients were using phytotherapy, falling to n = 35/69 (51%) at 24-month FU (highest in France 20% (n = 43/210)). Though defined disease progression occurred in ≤ 20%, with only 1% proceeding to surgical intervention, in both groups, clinically meaningful improvement was lower and symptom persistence was higher in PUP but similar in the treated (c-PTP) patients on phytotherapy compared to the other LUTS/BPE medication. Conclusion Low heterogeneous prescribing rates for phytotherapy were reported in both PUP and c-PTP cohorts over the 24-month FU. Although phytotherapy led to subjective improvements, healthcare practitioners should prescribe them with caution until higher quality evidence and guideline recommendations supporting its use are available.

  • Pre-therapy serum albumin-to-globulin ratio in patients treated with
           neoadjuvant chemotherapy and radical nephroureterectomy for upper tract
           urothelial carcinoma
    • Abstract: Purpose The accurate selection of patients who are most likely to benefit from neoadjuvant chemotherapy is an important challenge in oncology. Serum AGR has been found to be associated with oncological outcomes in various malignancies. We assessed the association of pre-therapy serum albumin-to-globulin ratio (AGR) with pathologic response and oncological outcomes in patients treated with neoadjuvant platin-based chemotherapy followed by radical nephroureterectomy (RNU) for clinically non-metastatic UTUC. Methods We retrospectively included all clinically non-metastatic patients from a multicentric database who had neoadjuvant platin-based chemotherapy and RNU for UTUC. After assessing the pretreatment AGR cut‐off value, we found 1.42 to have the maximum Youden index value. The overall population was therefore divided into two AGR groups using this cut‐off (low, < 1.42 vs high, ≥ 1.42). A logistic regression was performed to measure the association with pathologic response after NAC. Univariable and multivariable Cox regression analyses tested the association of AGR with OS and RFS. Results Of 172 patients, 58 (34%) patients had an AGR < 1.42. Median follow-up was 26 (IQR 11–56) months. In logistic regression, low AGR was not associated with pathologic response. On univariable analyses, pre-therapy serum AGR was neither associated with OS HR 1.15 (95% CI 0.77–1.74; p = 0.47) nor RFS HR 1.48 (95% CI 0.98–1.22; p = 0.06). These results remained true regardless of the response to NAC. Conclusion Pre-therapy low serum AGR before NAC followed by RNU for clinically high-risk UTUC was not associated with pathological response or long-term oncological outcomes. Biomarkers that can complement clinical factors in UTUC are needed as clinical staging and risk stratification are still suboptimal leading to both over and under treatment despite the availability of effective therapies.

  • Consultation on kidney stones, Copenhagen 2019: aspects of intracorporeal
           lithotripsy in flexible ureterorenoscopy
    • Abstract: Purpose To summarize current knowledge on intracorporeal laser lithotripsy in flexible ureterorenoscopy (fURS), regarding basics of laser lithotripsy, technical aspects, stone clearance, lithotripsy strategies, laser technologies, endoscopes, and safety. Methods A scoping review approach was applied to search literature in PubMed, EMBASE, and Web of Science. Consensus was reached through discussions at the Consultation on Kidney Stones held in September 2019 in Copenhagen, Denmark. Results and conclusions Lasers are widely used for lithotripsy during fURS. The Holmium laser is still the predominant technology, and specific settings for dusting and fragmenting have evolved, which has expanded the role of fURS in stone management. Pulse modulation can increase stone ablation efficacy, possibly by minimizing stone retropulsion. Thulium fibre laser was recently introduced, and this technology may improve laser lithotripsy efficiency. Small fibres give better irrigation, accessibility, and efficiency. To achieve optimal results, laser settings should be adjusted for the individual stone. There is no consensus whether the fragmentation and basketing strategy is preferable to the dusting strategy for increasing stone-free rate. On the contrary, different stone scenarios call for different lithotripsy approaches. Furthermore, for large stone burdens, all laser settings and lithotripsy strategies must be applied to achieve optimal results. Technology for removing dust from the kidney should be in focus in future research and development. Safety concerns about fURS laser lithotripsy include high intrarenal pressures and temperatures, and measures to reduce both those aspects must be taken to avoid complications. Technology to control these parameters should be targeted in further studies.

  • Quality of life and functional outcomes after radical cystectomy with
           ileal orthotopic neobladder replacement for bladder cancer: a multicentre
           observational study
    • Abstract: Purpose Ileal orthotopic neobladder (IONB) reconstruction is the preferred urinary diversion among selected patients who have undergone radical cystectomy (RC) for bladder cancer (BCa). There is insufficient data regarding patients’ quality of life (QoL), sexual and urinary outcomes. Our objectives were to assess QoL in a multicentre cohort study, and to identify related clinical, oncological and functional factors. Methods Patients who underwent RC with IONB reconstruction for BCa from 2010 to 2017 at one of the three French hospitals completed the following self-reported questionnaires: European Organization for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer specific instruments (QLQ-BLM30). To assess urinary symptoms, patients completed the Urinary Symptom Profile questionnaire (USP) and a three-day voiding diary. Univariate and multivariate analyses were computed to identify clinical, pathological, and functional predictors of global QoL score. Results Seventy-three patients completed questionnaires. The median age was 64 years and 86.3% were men. The median interval between surgery and responses to questionnaires was 36 months (range 12–96). Fifty-five percent of patients presented a high global QoL (EORTC-QLQC30, median score 75). A pre-RC American Society of Anesthesiologists score > 2, active neoplasia, sexual inactivity, and stress urinary incontinence were associated with a worse QoL. After a multivariate analysis, sexual inactivity was the only independent factor related to an altered QoL. Conclusion Patients with IONB reconstruction after RC have a high global QoL. Sexual activity could independently impact the global QoL, and it should be assessed pre- and post-operatively by urologists.

  • Comparison of scoring systems for predicting stone-free status and
           complications after retrograde ıntrarenal surgery
    • Abstract: Purpose To compare the effectiveness of scoring systems in predicting stone-free rates (SFR) and complications following retrograde intrarenal surgery (RIRS). Materials and methods We retrospectively analyzed 280 patients who underwent RIRS for kidney stones between 2016 and 2019. The Resorlu–Unsal Stone score (RUSS), Modified Seoul National University Renal Stone Complexity (S-ReSC) score, and R.I.R.S. scoring system score were calculated for each patient who was enrolled in the study. Subsequently, stone scoring systems were compared as to their predictive capability for SFR using receiver-operating characteristic curves. Furthermore, multivariate analysis was done to determine whether the scoring systems associated with SFR and complications. Results The median patient age was 44 (35–-56). The median RUSS, S-ReSC, and R.I.R.S scores were 0 (0–1), 1(1–2), and 6 (5–7), respectively. The overall SFR was 76.7%. The R.I.R.S. scoring system was found to have a higher predictive value in predicting postoperative SFR than the other two scoring systems (p < 0.001, AUC = 0,816). RUSS, R.I.R.S. score, and stone size were found to be independent predictive factors for SFR (p = 0.049, p = 0.024, p = 0.033, respectively). Complications were observed in 3.2%(9/280) of patients. Stone scoring systems were not statistically associated with complications. Operation duration was the only independent risk factor for complications (p = 0.010). Conclusions The R.I.R.S. scoring system was found to have a higher predictive value than RUSS and S-ReSC to predict SFR following RIRS in our study. However, none of the stone scoring systems was directly proportional to complications of RIRS.

  • Immunotherapy in non-muscle-invasive bladder cancer: current status and
           future directions
    • Abstract: Purpose Patients harboring high-grade non-muscle-invasive bladder cancer (NMIBC) experience high rates of both recurrence and progression. Currently, few treatment options besides cystectomy exist for this at-risk population, especially those with BCG-unresponsive disease. The purpose of this review is to present the current status and describe future directions of immunotherapy in NMIBC. Methods The PubMed and Google Scholar databases were searched for articles pertaining to immunotherapy in NMIBC. Relevant planned and ongoing clinical trials were identified using www.ClinicalTrials.gov. Published randomized control trials, reviews, other retrospective and prospective studies deemed relevant were used in this review paper. Results Novel immunotherapies used in the treatment of high-grade NMIBC and BCG-unresponsive disease allow patients more options and have the potential to reduce the need for radical cystectomy. Currently, several options target the programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) axis as this mechanism of immunotherapy has been shown to be effective in several cancers, including bladder, melanoma, and lung cancers. In addition, other immunotherapy options for the treatment of NMIBC include viral gene therapies, interleukin-15 superagonists, small molecule inhibitors of indoleamine (2,3)-dioxygenase 1, and vaccines. Conclusions The current landscape of immunotherapy in bladder cancer is rapidly evolving, with much literature pertaining to muscle-invasive and metastatic disease. However, the implementation of these treatment options in high-grade NMIBC may allow patients to avoid life-altering surgery. Reliable biomarkers for response are needed to further select patients who may benefit from such therapies.

  • Tea and coffee consumption and pathophysiology related to kidney stone
           formation: a systematic review
    • Abstract: Objective To explore the mechanisms behind the potential protective effect of coffee and tea consumption, regarding urinary stone formation, previously demonstrated in large epidemiological studies. Methods A systematic review was performed using the Medline, Cochrane library (CENTRAL) and Scopus databases, in concordance with the PRISMA statement. English, French and Spanish language studies, regarding the consumption of caffeinated and decaffeinated coffee and tea, and the relationship to urinary stone formation were reviewed. Meta-analyses, systematic reviews, case reports and letters, unpublished studies, posters and comments abstracts were excluded. Results As per the inclusion criteria, 13 studies were included in the final review. The major findings show that caffeine increases urinary excretion of calcium, sodium and magnesium, in addition to a diuretic action with consumption > 300–360 mg (approximately four cups of coffee). Together with other components of coffee, this beverage might have potential protective effects against the formation of urinary stones. Tea exerts many protective effects against stone formation, through the accompanying water intake, the action of caffeine and the effects of components with antioxidant properties. Conclusion Caffeine has a hypercalciuric effect, balanced partially by a diuretic effect which appears after consumption of large quantities of caffeine. The current available literature supports in general, a potentially protective role for tea against stone formation, mainly for green tea. Additional standardization in this field of research, through specification of tea and coffee types studied, and their respective compositions, is needed for further clarification of the relation between coffee, tea and urinary stones.

  • The impact of low pressure pneumoperitoneum in robotic assisted radical
           prostatectomy: a prospective, randomized, double blinded trial
    • Abstract: Background Robotic surgery has revolutionized postoperative outcomes across surgical specialties. However, the use of pneumoperitoneum comes with known risks given the change in physiological parameters that accompany its utilization. A recent internal review found a 7% decrease in postoperative ileus rates when utilizing a pneumoperitoneum of 12 mmHg over the standard 15 mmHg in robotic assisted radical prostatectomies (RARP). Objective The purpose of this study is to prospectively evaluate the utility of lower pressure pneumoperitoneum by comparing 8 mmHg and 12 mmHg during RARP. Design, setting and partcipants Patients were randomly assigned to undergo robotic assisted radical prostatectomy at a pneumoperitoneum pressure of 12 mmHg or 8 mmHg. Outcome measurements and statistical analysis The primary outcome was development of postoperative ileus and secondary outcomes were length of operation, estimated blood loss and positive surgical margin status. Results and limitations A total of 201 patients were analyzed; 96 patients at 8 mmHg and 105 patients at 12 mmHg. The groups were adequately matched as there were no differences between demographic parameters or medical comorbidities. There was a decrease in postoperative ileus rates with lower pneumoperitoneum pressures; 2% at 8 mmHg and 4.8% at 12 mmHg. There were no clinically significant differences in estimated blood loss, total length of operative time and positive margin status. Conclusions Lower pressure pneumoperitoneum during robotic assisted radical prostatectomy is non-inferior to higher pressure pneumoperitoneum levels and the experienced surgeon may safely perform this operation at 8 mmHg to take advantage of the proposed benefits.

  • No detrimental effect of a positive family history on postoperative
           upgrading and upstaging in men with low risk and favourable
           intermediate-risk prostate cancer: implications for active surveillance
    • Abstract: Purpose To assess whether a first-degree family history or a fatal family history of prostate cancer (PCa) are associated with postoperative upgrading and upstaging among men with low risk and favourable intermediate-risk (FIR) PCa and to provide guidance on clinical decision making for active surveillance (AS) in this patient population. Methods Participants in the German Familial Prostate Cancer database diagnosed from 1994 to 2019 with (1) low risk (clinical T1c–T2a, biopsy Gleason Grade Group (GGG) 1, PSA < 10 ng/ml), (2) Gleason 6 FIR (clinical T1c–T2a, GGG 1, PSA 10–20 ng/ml), and (3) Gleason 3 + 4 FIR (clinical T1c–T2a, GGG 2, PSA < 10 ng/ml) PCa who were subsequently treated with radical prostatectomy (RP) were analysed for upgrading, defined as postoperative GGG 3 tumour or upstaging, defined as pT3–pT4 or pN1 disease at RP. Logistic regression analysis was used to assess whether PCa family history was associated with postoperative upgrading or upstaging. Results Among 4091 men who underwent RP, mean age at surgery was 64.4 (SD 6.7) years, 24.7% reported a family history, and 3.4% a fatal family history. Neither family history nor fatal family history were associated with upgrading or upstaging at low risk, Gleason 6 FIR, and Gleason 3 + 4 FIR PCa patients. Conclusion Results from the current study indicated no detrimental effect of family history on postoperative upgrading or upstaging. Therefore, a positive family history or fatal family history of PCa in FIR PCa patients should not be a reason to refrain from AS in men otherwise suitable.

  • Oncological safety and functional outcomes of testosterone replacement
           therapy in symptomatic adult-onset hypogonadal prostate cancer patients
           following robot-assisted radical prostatectomy
    • Abstract: Purpose Testosterone replacement therapy (TRT) remains controversial in men with treated prostate cancer. We assessed its safety and functional impacts in patients after definitive surgical treatment with robotic-assisted radical prostatectomy (RARP). Methods We performed a retrospective analysis of 1303 patients who underwent RARP during the years 2006–2019. We identified men with symptoms of andropause and low serum testosterone who received TRT post-RARP; then we divided the cohort into two groups accordingly for comparison. Biochemical recurrence (BCR) was the primary endpoint. Secondary endpoints included functional outcomes. Predictors of BCR, including the effect of TRT on BCR, were evaluated using univariable and multivariable logistic regression. Results Among the forty-seven men who received TRT, the mean age was 60.83 years with a median follow-up of 48 months. Three (6.4%) and 157 (12.56%) patients experienced BCR in TRT and non-TRT groups, respectively. Baseline characteristics were similar between both groups except for higher mean BMI in the TRT group (p = 0.03). In the multivariate analysis (MVA), higher pre-RARP prostate-specific antigen (PSA) (p = 0.043), higher International Society of Urological Pathology score (p < 0.001), seminal vesical invasion (p = 0.018) and positive surgical margin (p < 0.001) were predictors of BCR. However, TRT was not (p = 0.389). In addition, there was a significant change in the Sexual Health Inventory for Men (p = 0.022), and serum testosterone level (p < 0.001) before and 6 months after initiation of TRT. Conclusion: Our findings suggest that TRT, in well-selected, closely followed, symptomatic men post-RARP is an oncologically safe and functionally effective treatment in prostate cancer patients post-RARP.

  • Adverse effects of chronic nitrofurantoin therapy in women with recurrent
           urinary tract infections in an outpatient setting
    • Abstract: Purpose To review the frequency of adverse events reported with nitrofurantoin (NF) in perimenopausal and menopausal women on prolonged daily prophylaxis in an outpatient setting. Methods Electronic medical records of women aged 50–95 prescribed NF by 2 primary urology providers for at least 3 consecutive months from 2006 to 2018 were retrospectively reviewed. Demographics, reason for the initiation, dose and duration of therapy, explanation of therapy interruptions, occurrence of adverse events, comorbid conditions, and relevant lab and imaging results were recorded. The number of months on prolonged therapy were summed. Results Of the 221 patients included, 167 (77%) were prescribed 100 mg of NF daily with a mean duration of therapy of 1.5 years. The most common indication for therapy was recurrent urinary tract infection prophylaxis. Breakthrough urinary tract infections developed in 88 (40%) patients on prolonged NF therapy but only 10 were not restarted on NF. Four patients (1.8%) were determined to have pulmonary adverse events and 1 (0.4%) developed elevated liver function tests. Conclusion In peri-menopausal and menopausal women, the risks and benefits of chronic NF therapy should be weighed by the clinician and patient prior to prescribing long term NF. Patients must be educated about the potential NF toxicities and clinically monitored for signs and symptoms of potential adverse events while on chronic NF therapy.

  • Operator-assisted vs self-achieved basketing during ureteroscopy: results
           from an in vitro preference study
    • Abstract: Objectives A recently introduced device (LithoVue Empower™ or LE, Boston Scientifics, USA) allows the surgeon to directly control the stone-retrieving basket without the need of an assistant during flexible ureteroscopy. We aimed to evaluate the stone-retrieval performance of this device. Methods We used a bench-training model for flexible ureteroscopy, the Key-box (K-Box®, Porgès-Coloplast, France), to compare the LE configured with a 1.9F stone-retrieval tipless basket (ZeroTip™, Boston Scientific, USA) and a traditional assistant-maneuvered 1.9F stone-retrieval tipless basket. Seven experienced endo-urologists and seven residents-in-training retrieved a fake stone from three different renal cavities of the K-Box with increasing access complexity first with the traditional basket and then with the LE device. We recorded retrieval time and all the operators filled in the NASA Task Load Index (TLI) for the self-evaluation of their performance. We then compared the use of LE in terms of retrieval time, failure rates, and NASA-TLI scores. Results Stone retrieval times and failure rates were similar according to the retrieval technique, although residents had non-statistically significant shorter times with the LE. NASA-TLI scores revealed lower frustration (p = 0.03) when LE was used by experienced urologists as compared to the traditional basketing. When stratifying the analyses according to surgical experience, fully trained urologists performed faster stone retrieval and showed lower effort scores than residents-in-training (p < 0.05). Conclusions The individually controlled retrieval system is an effective device assisting stone retrieval and does not necessitate specific training among experienced endo-urologists. Young residents might benefit from LE during their learning curve.
