  • Incidence, risk factors, and outcome of Clostridioides difficile infection
           following urological surgeries
    • Abstract: Purpose To assess the incidence, risk factors, and clinical outcomes associated with (Clostridioides difficile infection) CDI following urological surgery, which is the leading cause of nosocomial diarrhea and a growing public health burden. Methods We queried the National Surgical Quality Improvement Program (NSQIP) to identify patients undergoing urological surgery in 2015–2016. We evaluated the 30-day incidence and factors associated with postoperative CDI and 30-day hospital readmission and length of stay as secondary outcomes. Among the subset of patients undergoing radical cystectomy with urinary diversion (surgery with highest CDI incidence) we used multivariable logistic regression analysis to evaluate independent clinical and demographic factors associated with postoperative CDI. Results We identified 98,463 patients during the study period. The overall 30-day incidence of CDI was 0.31%, but varied considerably across surgery type. The risk of CDI was greatest following radical cystectomy with urinary diversion (2.72%) compared to all other urologic procedures (0.19%) and was associated with increased risk of hospital readmission (p < 0.0001), re-operation (p < 0.0001), and longer mean length of stay (p < 0.0001) in this cohort. Among patients undergoing radical cystectomy with urinary diversion, multivariable logistic regression revealed that preoperative renal failure (OR: 5.30, 95% CI 1.13–24.9, p = 0.035) and blood loss requiring transfusion (OR: 1.67, 95% CI 1.15–2.44, p = 0.0075) were independently associated with CDI. Conclusions In a nationally representative cohort, the incidence of CDI was low but varied substantially across surgery types. CDI was most common following radical cystectomy and associated with potentially modifiable factors such as blood transfusion and significantly longer length of stay.

  • Tea and coffee consumption and the risk of urinary stones—a systematic
           review of the epidemiological data
    • Abstract: Objective To explore the relationship between the consumption of coffee and tea with urolithiasis. We evaluated large epidemiological and small clinical studies to draw conclusions regarding their lithogenic risk. Methods A systematic review was performed using the Medline 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 disease were reviewed. Case reports and letters, unpublished studies, posters, and comments were excluded. Results As per the inclusion criteria, 13 studies were included in the final review. Most studies, including four large prospective studies and one meta-analysis, reported a reduced risk of stone formation for coffee and tea. Caffeine has a diuretic effect and increases the urinary excretion of calcium, but if these losses are compensated for, moderate caffeine intakes may have little or no deleterious effects. Green and Herbal teas infused for short time had low oxalate content compared to black tea. Conclusion There is no evidence that moderate consumption of coffee raises the risk for stone formation in healthy individuals, provided the recommended daily fluid intake is maintained. The currently available literature supports in general a protective role for tea against the stone formation, mainly for green tea. However, heterogeneity of published data and lack of standardization needs to be addressed before final and clear conclusions can be given to patients and to the public in general.

  • The efficacy and safety of Serenoa repens extract for the treatment of
           patients with chronic prostatitis/chronic pelvic pain syndrome: a
           multicenter, randomized, double-blind, placebo-controlled trial
    • Abstract: Purpose To perform a placebo-controlled trial to evaluate the efficacy and safety of Serenoa repens extract (SRE) for the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Methods We conducted a double-blind, randomized, placebo-controlled, multicenter, clinical phase 4 study of 221 patients with CP/CPPS across 11 centers. Participants were randomly assigned in a 2:1 ratio to receive SRE or placebo for 12 weeks. The primary efficacy endpoint was the change in total score on the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI). Secondary efficacy endpoints included improvements within each domain of NIH-CPSI, clinical response rate, and International Index of Erectile Function 5 items (IIEF-5). Results In total, 226 patients were enrolled and randomized between January 2017 and June 2018. Of these 221 patients were included in the intent-to-treat analysis: 148 in the SRE group and 73 patients in the placebo group. Compared to the placebo, SRE led to statistically significant improvements in the NIH-CPSI total score and sub-scores. The significant improvements of NIH-CPSI scores were established after 2 weeks from the first dose, and continued to the end of the treatment. Furthermore, a significantly higher rate of patients achieved a clinical response in the SRE group compared with that in the placebo group (73.0% vs 32.9%, P < 0.0001). Only minor adverse events were observed across the entire study population. Conclusions SRE was effective, safe, and clinically superior to placebo for the treatment of CP/CPPS.

  • Prospective trial of regional (hockey-stick) prostate cryoablation:
           oncologic and quality of life outcomes
    • Abstract: Purpose To report long-term follow-up of the efficacy of subtotal prostate ablation using a “hockey-stick” template, including oncologic control and quality of life (QoL) impact. Methods We performed a prospective controlled trial to evaluate the efficacy of subtotal prostate ablation in selected men with baseline and confirmatory biopsy showing grade group (GG) 1–2 prostate cancer. “Hockey-stick” cryoablation that included the ipsilateral hemi-gland and contralateral anterior prostate was performed. Prostate biopsies and QOL queries were performed at 6, 18 and 36 months following regional ablation, and follow-up was updated to include subsequent clinic visits. Results Between August 2009 and January 2012, 72 men were screened for eligibility and 47 opted to undergo confirmatory biopsy. Of these, 23 were deemed eligible and treated with regional cryoablation. Median age was 64 years. Median follow-up was 74 months. A single patient had < 1 mm of in-field viable tumor with therapy effect on 36-month biopsy. At time of last follow-up, a total of 12/23 (52%) patients did not have evidence of disease, all patients had preserved urinary control with no patients requiring pads for urinary incontinence. Sexual decline was significant at 3 and 6 months (P < 0.01 for both), though improvement was seen at subsequent time points. Conclusion Subtotal (hockey-stick template) cryoablation of the prostate provides oncologic control to targeted tissue in a generally low-risk group with minimal impact on sexual and urinary function. Further studies are needed to evaluate this ablation template in the MRI-targeted era and higher risk populations.

  • Available active surveillance follow-up protocols for small renal mass: a
           systematic review
    • Abstract: Purpose To evaluate follow-up strategies for active surveillance of renal masses and to assess contemporary data. Methods We performed a comprehensive search of electronic databases (Embase, Medline, and Cochrane). A systematic review of the follow-up protocols was carried out. A total of 20 studies were included. Result Our analysis highlights that most of the series used different protocols of follow-up without consistent differences in the outcomes. Most common protocol consisted in imaging and clinical evaluation at 3, 6, and 12 months and yearly thereafter. Median length of follow-up was 42 months (range 1–137). Mean age was 74 years (range 67–83). Of 2243 patients 223 (10%) died during the follow-up and 19 patients died of kidney cancer (0.8%). The growth rate was the most used parameter to evaluate disease progression eventually triggering delayed intervention. Maximal axial diameter was the most common method to evaluate growth rate. CT scan is the most used, probably because it is usually more precise than kidney ultrasound and more accessible than MRI. Performing chest X-ray at every check does not seem to alter the clinical outcome during AS. Conclusion The minimal cancer-specific mortality does not seem to correlate with the follow-up scheme. Outside of growth rate and initial size, imaging features to predict outcome of RCC during AS are limited. Active surveillance of SRM is a well-established treatment option. However, standardized follow-up protocols are lacking. Prospective, randomized, trials to evaluate the best follow-up strategies are pending.

  • The use of Lactobacillus casei DG® prevents symptomatic episodes and
           reduces the antibiotic use in patients affected by chronic bacterial
           prostatitis: results from a phase IV study
    • Abstract: Purpose To evaluate the efficacy of Lactobacillus paracasei CNCM I-1572 (L. casei DG®) in both prevention of symptomatic recurrences and improvement of quality of life in patients with chronic bacterial prostatitis (CBP). Methods Patients with CBP attending a single Urological Institution were enrolled in this phase IV study. At enrollment, all patients were treated with antibiotics in agreement with EAU guidelines and then were treated with L. casei DG® (2 capsules/day for 3 months). Clinical and microbiological analyses were carried out before (enrollment, T0) and 6 months (T2) after the treatment. Both safety and adherence to the treatment were evaluated 3 months (T1) after the enrollment. NIH Chronic Prostatitis Symptom Index (CPSI), International Prostate Symptom Score (IPSS) and Quality of Well-Being (QoL) questionnaires were used. The outcome measures were the rate of symptomatic recurrence, changes in questionnaire symptom scores and the reduction of antibiotic use. Results Eighty-four patients were included. At T2, 61 patients (72.6%) reported a clinical improvement of symptoms with a return to their clinical status before symptoms. A time dependent improvement in clinical symptoms with significant changes in NIH-CPSI, IPSS and QoL (mean difference T2 vs T0: 16.5 ± 3.58; − 11.0 ± 4.32; + 0.3 ± 0.09; p < 0.001), was reported. We recorded that L. casei DG® treatment induced a statistically significant decrease in both (p < 0.001) symptomatic recurrence [1.9/3 months vs 0.5/3 months] and antibiotic use [− 7938 UDD]. No clinically relevant adverse effects were reported. Conclusions L. casei DG® prevents symptomatic recurrences and improves the quality of life in patients with CBP, reducing the antibiotic use.

  • Should Grade Group 1 (GG1) be called cancer'
    • Abstract: Introduction ISUP Grade Group 1 prostate cancer is the lowest histologic grade of prostate cancer with a clinically indolent course. Removal of the term ‘cancer’ has been proposed and has historical precedent both in urothelial and thyroid carcinoma. Methods Evidence-based review identifying arguments for and against Grade Group 1 being referred to as cancer. Results Grade Group 1 has histologic evidence of tissue microinvasion and 0.3–3% rate of extraprostatic extension. Genomic evaluation suggests overlap of a minority of Grade Group 1 cancers with those of Grade Group 2. Conversely, Grade Group 1 tumors appear to have distinct genetic and genomic profiles from Grade Group 3 or higher tumors. Grade Group 1 has no documented ability for regional or distant metastasis and long-term follow up after treatment or active surveillance is safe with excellent oncologic outcomes. Discussion Grade Group 1 prostate cancer, while showing evidence of neoplasia on histology has a remarkably indolent natural history more akin to non-neoplastic precursor lesions. Consideration should be given to renaming Grade Group 1 prostate cancer, which has the potential to minimize overtreatment, treatment-related side effects, patient anxiety, and financial burden on the healthcare system.

  • Higher than expected and significantly increasing incidence of upper tract
           urothelial carcinoma. A population based study
    • Abstract: Purpose To register all cases of urothelial cancer and renal cell carcinoma (RCC) in Norway during 1999–2018 to obtain the contemporary incidence of UTUC and UTUC incidence relative to other urothelial cancers and RCC. Further to analyse possible changes over time regarding UTUC incidence, UTUC patient characteristics, tumour characteristics and survival. Methods 3502 cases registered with ICD code C65 and C66 during 1999–2018 at the Norwegian cancer registry were entered into a database. After a selection process 3096 cases were included in the study. The crude incidences of UTUC were calculated for each year adjusting for the corresponding population data. Age-standardized rates adjusting to the European standard population (2013) were calculated. Comparisons were made with other cases of urothelial cancer and RCC. For changes over time, the material was split into 5-year periods. Regression analysis was used to calculate yearly changes and for assessing statistical significance. Survival outcomes were calculated using the Kaplan–Meier method. Results The overall age-standardized incidence rate was 3.88, increasing from 3.21 to 4.70 from first to last 5-year periods. The increase affected all ages except those < 60 years of age, and were observed regardless of gender or anatomical location. UTUC constituted 11.8% of all urothelial cancers, increasing from 9.9 to 12.8%. Mean patient age at diagnosis increased from 71.5 to 73.4 years. The 5-years Cancer-specific survival improved from 57.4 to 65.4%. Conclusion The incidence of UTUC was higher than expected and increasing. Patient age at diagnosis was increasing.

  • Clinical, surgical, pathological and follow-up features of kidney cancer
           patients with Von Hippel-Lindau syndrome: novel insights from a large
    • Abstract: Purpose To investigate the natural history and follow-up after kidney tumor treatment of Von Hippel-Lindau (VHL) patients. Materials and methods A multi-institutional European consortium of patients with VHL syndrome included 96 non-metastatic patients treated at 9 urological departments (1987–2018). Descriptive and survival analyses were performed. Results and limitations Median age at VHL diagnosis was 34 years (IQR 25–43). Two patients (2.1%) showed only renal manifestations at VHL diagnosis. Concomitant involvement of Central Nervous System (CNS) vs. pancreas vs. eyes vs. adrenal gland vs. others were present in 60.4 vs. 68.7 vs. 30.2 vs. 15.6 vs. 15.6% of patients, respectively. 45% of patients had both CNS and pancreatic diseases alongside kidney. The median interval between VHL diagnosis and renal cancer treatment resulted 79 months (IQR 0–132), and median index tumor size leading to treatment was 35.5 mm (IQR 28–60). Of resected malignant tumours, 73% were low grade. Of high-grade tumors, 61.1% were large > 4 cm. With a median follow-up of 8 years, clinical renal progression rate was 11.7% and 29.3% at 5 and 10 years, respectively. Overall mortality was 4% and 7.5% at 5 and 10 years, respectively. During the follow-up, 50% of patients did not receive a second active renal treatment. Finally, 25.3% of patients had CKD at last follow-up. Conclusions Mean period between VHL diagnosis and renal cancer detection is roughly three years, with significant variability. Although, most renal tumors are small low-grade, clinical progression and mortality are not negligible. Moreover, kidney function represents a key issue in VHL patients.

  • Evaluating outcomes of complete supine percutaneous nephrolithotomy for
           staghorn vs multiple non-staghorn renal stones: a 10-year study
    • Abstract: Purpose To evaluate the outcomes of complete supine percutaneous nephrolithotomy (csPCNL) for staghorn stones and multiple large non-staghorn stones. Methods The records of 886 patients who underwent csPCNL from September 2009 to October 2019 were considered. Out of them, 201 cases met the eligibility criteria and they were divided into three groups: 63 cases of staghorn, 68 cases of multiple medium (20 mm < diameter ≤ 30 mm) non-staghorn and 70 cases of multiple large non-staghorn (> 30 mm) stones. Almost all outcomes and stone-related factors were analyzed. Results There was not any significant difference regarding age, body mass index, history of urinary tract infection, transfusion rate, complication rate, pre and post-surgery serum creatinine, hemoglobin drop and total hospital stay between the three groups. Stone free rate was 98.5% in multiple medium group, 97.1% in multiple large group and 84.1% in staghorn group (P = 0.001). The operation duration was significantly shorter for the multiple medium group (P < 0.001) but it was not significantly different between the multiple large non-staghorn and staghorn group. Conclusion The results demonstrated that almost all outcomes were not significantly different between the three groups (especially between staghorn and larger non-staghorn ones). These findings reveal that surgeons could choose csPCNL for treatment of staghorn stones and multiple large non-staghorn stones and consider staghorn stones as challenging as multiple large (especially diameter > 30 mm) non-staghorn stones.

  • Risk of UTI in kidney stone formers: a matched-cohort study over a median
           follow-up of 19 years
    • Abstract: Purpose To describe risk of UTI in Stone formers comparing to non-stone formers. Methods Retrospective cohort study using electronic records for patients across southern England. Stone formers referred to a tertiary referral centre in Southern England, comparator patients were age and sex matched with 3:1 ratio from same database. Those with no documentation were excluded. UTI defined using ICD-10 codes. Risk of UTI presented as hazard ratio with 95% confidence interval, generated using cox regression. Sample size calculated using 80% power and significance set at 0.05. Results Eight hundred and nineteen stone formers were included after 1000 records were screened for inclusion, with 2477 age and sex matched non-stone formers extracted from the same database. Sample size was calculated at 287 per group. Stone formers were at significantly increased risk of developing a UTI (HR 5.67; 95% CI 4.52–7.18, p < 0.001). Median follow-up was 19 years (IQR: 15–22). Conclusions Kidney stone formers are at increased risk of developing urinary tract infections.

  • Independent predictors of mortality for patients with traumatic renal
    • Abstract: Purpose To investigate the parameters of renal trauma, including emergent intervention type, that predict the mortality of patients with traumatic renal injury. Methods A retrospective database analysis was performed on patients who sustained a traumatic renal parenchymal injury identified by the 2017 National Trauma Data Bank. Data were analyzed to identify differences in hospital length of stay, ER and hospital disposition, and mortality based on patient age, gender, race, Injury Severity Score, renal injury grade, and need for emergent intervention (angioembolization versus open surgery). Logistic regression was used to correlate intervention type and trauma parameters to mortality. Results A total of 4,876 of 1,004,440 trauma patients (0.49%) had a traumatic renal injury. Of those, 220 (4.5%) underwent an emergent intervention—29 (0.59%) angioembolization and 191 (3.9%) open renal surgery. 83 patients with a blunt renal trauma (2.0%) underwent renal intervention, whereas 136 (21.0%) with a penetrating injury required a procedure. Forty-five of the 220 patients (20.5%) who had a renal intervention died, while 377 of 4,656 (8.1%) who did not have an intervention died. Multiple logistic regression identified black race, age > 45 years, penetrating trauma, and ISS > 15 to be independent predictors of mortality. Neither angioembolization nor open renal surgery was associated with a significantly higher likelihood of mortality in the multivariable model. Conclusion While procedural interventions are associated with higher mortality for patients with traumatic renal injury, other factors, such as race, age, trauma type, and injury severity may be more predictive of death under care.

  • The effect of β 3 -adrenoceptor gene polymorphisms on lower urinary
           tract function in males
    • Abstract: Purpose To clarify the role of Trp64Arg polymorphisms of the gene encoding the β3-adrenoceptor for lower urinary tract function in males, the present study investigated the association between the Trp64Arg polymorphisms and lower urinary tract symptoms (LUTS) and function. Methods This prospective observational study included patients who underwent robot-assisted radical prostatectomy. Before surgery, blood samples were collected, and analyses of β3-adrenoceptor gene polymorphism were performed using the real-time polymerase chain reaction. The present cohort was divided into patients with wild type (Trp64Trp) and with variant type (Trp64Arg + Arg64Arg), and LUTS and lower urinary tract function before surgery were compared between them. Results Wild type was found in 247 patients, with variant type in 129. There were no significant differences in LUTS between the two groups. Residual urine volume (PVR) (wild type: variant type = 47 ± 53 mL: 58 ± 77 mL, P = 0.04) and voiding time on uroflowmetry (wild type: variant type = 29 ± 15 s: 33 ± 17 s, P = 0.04) were significantly increased in the variant type. Conclusion The Trp64Arg variant of the β3-adrenoceptor gene significantly increased PVR and voiding time in men. However, it was not significantly associated with the emergence of LUTS. Thus, since the effect of β3-adrenoceptor gene polymorphisms on the genitourinary organs might be weak, whether men possess the Trp64Arg variant of the β3-adrenoceptor gene might not critically affect urinary quality of life, but modestly affect the lower urinary tract function.

  • Role of MRI for the detection of prostate cancer
    • Abstract: Abstract The use of multiparametric MRI has been hastened under expanding, novel indications for its use in the diagnostic and management pathway of men with prostate cancer. This has helped drive a large body of the literature describing its evolving role over the last decade. Despite this, prostate cancer remains the only solid organ malignancy routinely diagnosed with random sampling. Herein, we summarize the components of multiparametric MRI and interpretation, and present a critical review of the current literature supporting is use in prostate cancer detection, risk stratification, and management.

  • A randomized controlled trial comparing high and medium power settings for
           holmium laser enucleation of prostate
    • Abstract: Purpose To report the results of a randomized controlled trial comparing outcomes between medium power (MP) and high power (HP) laser settings for HoLEPs. Methods The primary objective was to compare the enucleation efficiency (EE) of HP- HoLEP (80–100 W) with MP-HoLEP (50 − 60 W). The secondary objectives were to compare treatment efficacy and safety between both groups. To show a 25% difference in EE, a sample size of 45 individuals per treatment arm was required (alpha = 0.05; Beta = 0.80). Patients demographic and perioperative factors were analyzed, including EE, hemoglobin drop, duration of catheterization, and length of hospital stay. The surgical outcome was evaluated with AUA symptom score, maximum flow rate, postvoid residual urine, and complications to assess differences between MP and HP HoLEP at baseline, 3 months, 1, and 5 years. Quantitative outcomes were compared with independent sample t tests (2-tailed) and qualitative outcomes were compared with chi-square tests. Results Preoperative data with the exception of indication for surgery were comparable in both treatment arms. There was no statistically significant difference in enucleation efficiency between the HP-HoLEP and MP-HoLEP laser setting (0.97 ± 0.47 vs. 0.85 ± 0.47 gm/min, p = 0.209). MP laser settings did not increase perioperative or postoperative complications and resulted in durable outcome comparable with HP laser settings at 5-year follow-up. Conclusions MP-HoLEP is safe and efficient and does not compromise the outcome for HoLEPs when compared with HP-HoLEP.

  • Endoscopic surgical simulation using low-fidelity and virtual reality
           transurethral resection simulators in urology simulation boot camp course:
           trainees feedback assessment study
    • Abstract: Objectives The objective of our study was to study trainees’ feedback and rating of models for training transurethral resection of bladder lesions (TURBT) and prostate (TURP) during simulation. Methods The study was performed during the ‘‘Transurethral resection (TUR) module” at the boot camp held in 2019. Prior to the course, all trainees were required to evaluate their experience in performing TURBT and TURP procedures. Trainees simulated resection on two different models; low-fidelity tissue model (Samed, GmBH, Dresden, Germany) and virtual reality simulator (TURPMentor, 3D Systems, Littleton, US). Following the completion of the module, trainees completed a questionnaire using a 5-point Likert scale to evaluate their assessment of the models for surgical training. Results In total, 174 simulation assessments were performed by 56 trainees (Samed Bladder–40, Prostate–45, TURPMentor Bladder–51, Prostate–37). All trainees reported that they had performed < 50 TUR procedures. The Samed model median scores were for appearance (4/5), texture (5/5), feel (5/5) and conductibility (5/5). The TURPMentor median score was for appearance (4/5), texture and feel (4/5) and conductibility (4/5). The most common criticism of the Samed model was that it failed to mimic bleeding. In contrast, trainees felt that the TURPMentor haptic feedback was inadequate to allow for close resection and did not calibrate movements accurately. Conclusions Our results demonstrate that both forms of simulators (low-fidelity and virtual reality) were rated highly by urology trainees and improve their confidence in performing transurethral resection and in fact complement each other in providing lower tract endoscopic resection simulation.
