  • Jackstone in the Kidney: An Unusual Calculus

    • Abstract: Jackstones are stones in the urinary tract that have the characteristic appearance resembling six-pointed toy jacks. They are nearly always reported to occur in the urinary bladder, and the occurrence in less capacious renal pelvis is unusual. We report a solitary, typical jackstone in the renal pelvis without significant outflow obstruction that was successfully treated with retrograde intrarenal surgery followed by extracorporeal shockwave lithotripsy. This highlights the complex pathophysiological mechanisms in stone formation which needs to be further studied. It is important to recognize the characteristic shape of the renal calculi on the radiological investigation in the diagnosis of the jackstones.

  • A Rare Presentation of Renal Papillary Necrosis in a COVID-19-Positive

    • Abstract: In this case report we describe an unusual presentation of severe acute papillary necrosis in a COVID-19-positive patient. An emergency flexible ureteroscopy greatly helped in the establishment of the diagnosis. In the international literature, there is a paucity of intraoperative endoscopic images representing severe renal papillary necrosis. We present a case of severe acute renal papillary necrosis in a 49-year-old south-Asian, COVID-19-positive male patient who needed emergency urological intervention for macroscopic hematuria and urinary retention due to clot formation in the urinary bladder. The patient underwent emergency cystoscopy, clot evacuation, and by rigid and flexible ureteroscopy. The diagnosis was only confirmed in the postoperative period, retrospectively. Finally, the patient fully recovered due to the multidisciplinary management. Diagnosis of rare clinical entities can be sometimes challenging in the everyday routine practice. Having atypical clinical course, the surgeon should be prepared and sometimes must take responsible decisions promptly, even if needed intraoperatively, to manage unexpected findings in order to get the right diagnosis without compromising the patient’s safety.

  • Long-Term Undesirable Consequences of Penile Skin Island Flap to Correct
           Penoescrotal Transposition: A Case Report and Review of Literature

    • Abstract: Hypospadias is a congenital malformation of the male lower urinary tract, consisting of a ventral urethral opening proximal to the glans penis. This condition is corrected surgically in the paediatric age, with a great variety of techniques available. Traditionally, a tubularized genital skin was used for one- or two-stage repairs. Nowadays, the tendency is to use preputial or oral mucosa grafts, dorsally located, to avoid diverticula formation and prevent hair growth in the neourethra. We present a case of a patient born with proximal hypospadias with penoscrotal transposition, surgically corrected in his childhood, using dorsal penile skin island flap. The patient is referred to urology consultation in his adulthood for a weak urinary stream, recurrent infections, and a large amount of hair exiting through the urethral meatus.

  • Suprapubic Catheter Migration: A Review of a Rare Complication

    • Abstract: Background. Suprapubic catheter migration to the vesicoureteral junction is an unusual complication, causing an obstruction that led to hydronephrosis and dilation of the pelvicalyceal system. Case presentation. A 30-year-old man with a suprapubic catheter (SPC) that was inserted one month before this current Emergency Department (ED) visit had severe left flank pain for 48 hours. The SPC was inserted in the context of urethral injury after falling astride. Point-of-Care Ultrasound (POCUS) showed a semifilled urinary bladder and moderate hydronephrosis on the left side. A computed tomography scan (CT scan) of the abdomen was performed and showed migration of the suprapubic catheter’s tip into the left vesicoureteral junction, causing ureteral obstruction dilation of the ipsilateral pelvicalyceal system. The suprapubic catheter was changed in the ED, causing relief of symptoms, and the patient was referred to the urology department for follow-up. It was uneventful on the follow-up from the SPC clinic. Conclusions. This case report describes a rare complication of migration of the suprapubic catheter to the vesicoureteral junction causing acute ureteral obstruction and hydronephrosis.

  • A Unique Case of Incomplete Bifid Ureter and Associated Arterial

    • Abstract: Introduction. Urogenital and vascular anomalies, including a left duplex kidney and a left aberrant renal artery that gave rise to the left ovarian artery, were observed in a 77-year-old female cadaver during a routine dissection. Description. A left aberrant renal artery, which gave rise to the left ovarian artery, was observed originating from the aorta 4 cm below the left renal artery. Two independent contributions to a bifid ureter were found originating from the hilum of the left kidney. These two contributions descended 12.4 cm and 10.6 cm, respectively, posterior to the left aberrant renal artery and lateral to the left ovarian artery before uniting anterior to the psoas major muscle to descend 12.7 cm to the bladder. Significance. While the duplex kidney is a relatively common congenital anomaly that can be asymptomatic, it can also potentially be associated with compression of renal vasculature or the ureter. Ureteral compression can then result in several pathologies including reflux, urinary tract infection (UTI), ureteropelvic junction obstruction, or hydronephrosis. Compression of renal and ovarian vasculature can result in altered blood flow to the kidney and ovary, potentially causing fibrosis, atrophy, or organ failure. Current imaging techniques alone are insufficient for correct diagnostics of such complications, and they must be supplemented with a thorough understanding of the respective anatomical variations.

  • Metastatic Urothelial Carcinoma from Transplanted Kidney with Complete
           Response to an Immune Checkpoint Inhibitor

    • Abstract: Background. Donor-derived malignancy is a rare complication in patients who undergo organ transplant. Approaches to treatment have largely been individualized based on clinical circumstances given the lack of evidence-based guidelines, with therapeutic options ranging from discontinuation of immunosuppression and transplantectomy to the addition of chemotherapy or radiotherapy. Case Presentation. Herein, we describe a 60-year-old woman with metastatic donor-derived upper tract urothelial carcinoma (UTUC) discovered nine years postrenal transplant. Molecular diagnostic studies using polymerase chain reaction amplification of short tandem repeat alleles and HLA tissue typing proved that the urothelial carcinoma originated from donor tissue. She achieved sustained complete remission with transplant nephroureterectomy, retroperitoneal lymphadenectomy, immunosuppression withdrawal, and immunotherapy with pembrolizumab. Routine radiologic surveillance has demonstrated 15-month progression-free survival to date off pembrolizumab, and she is now under consideration for retransplantation. Conclusions. Immunotherapy using checkpoint inhibitors can serve as a novel treatment option for patients in the clinical predicament of having a solid organ transplant and simultaneous metastatic malignancy. In this report, we also discuss the oncogenic potential of BK virus, the use of checkpoint inhibitors in urothelial carcinoma, and the feasibility of retransplant for this patient population.

  • Near-Miss Diagnoses of Solitary Bladder Tumors Highlight the Importance of
           Immunohistochemical Staining

    • Abstract: We report three cases of prostate adenocarcinoma appearing as bladder masses and misdiagnosed as muscle-invasive bladder cancer (MIBC). Patients were referred for consideration for radical cystectomy after initial pathological diagnosis suggested poorly differentiated bladder cancer. Pathological review of tissue samples and subsequent immunohistochemical (IHC) staining confirmed advanced prostatic adenocarcinoma. Systemic therapy for prostate cancer was then initiated. These cases highlight the importance of patient history, physical exam, and IHC staining in consideration of a bladder mass, as these patients may have been subject to undue morbidity and surgical intervention without accurate pathologic diagnosis.

  • Repair of Inguinal Bladder Hernias Concomitant with Localized Prostate
           Cancer: A Case Report and Review of the Literature

    • Abstract: This study reports two rare cases of inguinal bladder hernias accompanied by localized prostate cancers. They were treated with simultaneous repair of inguinal bladder hernias and open retropubic radical prostatectomy. Additionally, we performed a literature review on previous inguinal bladder hernias case reports. In this present study, the first patient was a 64-year-old man histopathologically diagnosed with prostate cancer; computed tomography for staging of prostate cancer revealed a “Pelvic Mickey Mouse Sign.” The second patient was a 75-year-old man with right inguinal swelling that gradually increased in size for 30 years. He was referred to our department due to nocturia and urge incontinence. His prostate-specific antigen level was 4.17 ng/mL, and a transrectal prostate biopsy revealed prostate cancer. Preoperative imaging studies revealed a right hernia wherein most of the bladder slid beyond the inguinal channel filling the scrotum. Both patients underwent the Lichtenstein technique for inguinal bladder hernias simultaneously with retropubic radical prostatectomy using separate surgical incisions to avoid urinary contamination of the mesh. In our comprehensive review of patients who underwent inguinal bladder hernias surgical repair, there were 51 cases (50 males and 1 female). The mean patient age was years. Five cases demonstrating concomitant prostate cancer were observed. This present case report is the first to describe two patients who underwent surgeries for the simultaneous repair of inguinal bladder hernias and retropubic radical prostatectomy with separate surgical incisions. Supposedly, this simultaneous approach is suitable for concomitant inguinal bladder hernias and prostate cancer treatment.

  • Late-Onset Bilateral Choroidal Metastases from Clear Cell Renal Cell

    • Abstract: Aim. To present a case of clear cell renal cell carcinoma with late-onset bilateral choroidal metastases. Case Report. A 57-year-old male patient in the Oncology Clinic complained of reduced vision in the right eye (OD) for 7 days. The patient, who was under immunotherapy with nivolumab, had been diagnosed with clear cell renal cell carcinoma in the left kidney 15 years ago that recurred in the right kidney before 2 years. Metastases in the brain, lungs, and bones had also been diagnosed. On ophthalmological examination, the visual acuity was 20/50 OD and 20/20 in the left eye (OS). Dilated fundus examination in OD revealed a single raised oval-shaped yellowish choroidal nodule infratemporally with macular involvement. A similar lesion, sparing the macula, was observed in OS. Fundus autofluorescence revealed diffuse punctate hyperautofluorescence on the lesions. Serous macular detachment was also observed in OD. A standardized A-scan ultrasound demonstrated an irregular structure of the lesions with moderate to high internal reflectivity. Based on the history and clinical and echographic characteristics, the diagnosis of bilateral choroidal metastases from renal cell carcinoma was set. Conclusion. Choroidal metastases from the primary renal tumor are extremely rare. The time interval between primary malignancy and choroidal metastasis is reported to be 12-96 months. Bilateral choroidal metastases have been described in 9 cases. We describe a rare case where bilateral choroidal metastases were diagnosed 15 years after the initial diagnosis of clear cell renal cell carcinoma.

  • Zinner’s Syndrome: A Rare Diagnosis of Dysuria Based on Imaging

    • Abstract: Zinner’s syndrome is a rare congenital malformation of the seminal vesicle and ipsilateral upper urinary tract, due to developmental arrest in early embryogenesis of the Müllerian duct. Clinical presentation is nonspecific and includes voiding symptoms such as dysuria, ejaculatory disorders, and hypogastric or perineal pain. The diagnosis is made with imaging techniques, notably Magnetic Resonance Imaging (MRI) which remains the gold standard exam for diagnosis confirmation and therapeutic management. Treatment options depend on the severity of symptoms, the size of the cyst, and the complications. Herein, we report a rare case of a 33-year-old young patient who presented recurrent dysuria and ejaculatory disorders for the last 5 years. Imaging studies revealed an empty left renal fossa, with cystic pelvic mass related to the seminal vesicle and which was compatible with the diagnosis of Zinner’s syndrome. The patient underwent successful laparoscopic removal of the cyst and seminal vesicle, with total disappearance of urinary and sexual complaints with a 3-year follow-up.

  • Spontaneous Intraperitoneal Rupture of Bladder Diverticulum: A Rare Cause
           of Peritonitis

    • Abstract: Spontaneous rupture of acquired bladder diverticulum in an adult patient is an extremely rare pathological entity with only 15 cases reported in the available literature. Etiologies are dominated by bladder outlet obstruction, represented mainly by benign prostatic hypertrophy (BPH) in elderly men. Clinical presentation is nonspecific, leading to delayed diagnosis and treatment. Surgical management is the standard approach for intraperitoneal rupture of bladder diverticulum. The prognosis depends on the earliness of treatment, associated comorbidity, and the nature of underlying diseases. Herein, we report a rare case of a 65-year-old male patient, who presented a spontaneous rupture of a large acquired bladder diverticulum, secondary to acute urinary retention complicating benign prostatic hypertrophy. The diagnosis was suspected in the presence of generalized peritonitis associated with lower urinary tract symptoms (LUTS) and was confirmed accurately and promptly by a computed tomography (CT) of the abdomen and pelvis. The patient underwent a successful surgical excision of the diverticulum and bladder repair without delay. The postoperative course was uneventful, and he was discharged from the hospital without any complication.

  • Torsion of an Epididymal Cyst: A Rare Finding on Scrotal Exploration for
           Acute Scrotum

    • Abstract: Torsion of epididymal cyst (EC) is an exceedingly rare cause of acute scrotum in both children and adults. We add our case as the ninth case to literature which was an 8-year-old child presented with features of acute scrotum with history of EC on conservative management. Doppler sonography showed perfused normal bilateral testes and a septate cystic lesion of right epididymis. On scrotal exploration, we found a haemorrhagic cystic lesion attached to the upper pole of right testis and twisted for 540 degrees with normal testis and appendage. Cyst was excised, and histopathology revealed a haemorrhagic EC. Our case was peculiar due to, presenting as acute scrotum in a child of 1-10 years age group who was conservatively managed for right-sided EC and presence of 540 degrees torsion.

  • A Case of Papillary Urothelial Neoplasm of Low Malignant Potential
           (PUNLMP) in Childhood

    • Abstract: Urothelial carcinoma (UC) of the bladder is exceedingly rare in the pediatric population. It commonly presents as isolated hematuria. Considering the age group, the physician’s low index of suspicion causes a delay in diagnosis. We present a seven-year-old girl complaining of dysuria and painless, intermittent hematuria. She was misdiagnosed with urinary tract infection several times. Although the initial ultrasound showed no abnormality, the second ultrasound after one year detected the tumor. The confirmation and resection are simultaneously achieved by cystoscopy. We concluded that chemotherapy is unnecessary due to the tumor’s low-grade nature and the absence of detrusor involvement. One-year follow-up showed no relapse.

  • Unusual Bladder Metastasis from a Primary Gastric Carcinoma: Two Case
           Reports and Review of Literature

    • Abstract: Primary bladder cancer is a frequent malignancy in the urology field, whereas secondary bladder neoplasms from a distant organ are extremely rare. This paper aims to report two rare cases of a secondary tumor of the urinary bladder from a primary gastric tumor and to perform a literature review of similar reported cases in order to better characterize its clinicopathological features and diagnosis in effort to shed light on this rare condition. The final diagnosis of secondary adenocarcinoma was made histologically after transurethral biopsy or resection of the bladder lesion. In one case, the bladder metastasis was a synchronous metastasis, and in the second case, it occurred under chemotherapy five months after initial diagnosis with gastric adenocarcinoma. Secondary adenocarcinoma of the bladder is extremely rare but should be considered when evaluating a bladder lesion in a patient treated for gastric cancer or presenting with gastric symptoms.

  • Pathogenesis, Diagnosis, and Management of Splenogonadal Fusion: A
           Literature Review

    • Abstract: Introduction. Splenogonadal fusion is a rare congenital anomaly, defined by the presence of ectopic splenic tissue caused by an abnormal connection between the spleen and the gonad or mesonephrotic derivatives during the embryonic period. Materials and Methods. By reporting an observational case and performing a review of the literature according to the CARE guidelines (using the PubMed database and guidelines from urology, general surgery, and pediatric learned societies), we present the embryological genesis of the splenogonadal fusion, the associated anatomical anomalies, and the diagnostic procedure. Observation. We report the case of a patient aged 45, with no notable history, reporting left testicular pain. A small nodule on the upper pole of the left testicular was clinically palpable. Tumor markers were normal, and scrotal ultrasound depicted a hypoechoic hypervascular nodule measuring . After validation in a multidisciplinary oncology consultation meeting and opinion from a uro-andrologist expert, the patient underwent an inguinal lumpectomy with an extemporaneous examination which did not objectify any signs of malignancy. Ultimately, it is a normal spleen tissue in the testicular ectopic position. Discussion. Splenogonadal fusion corresponds to a rare congenital malformation; less than 200 cases have been published in the literature, most often affecting boys, with a sex ratio of 15/1. Two types are described, depending on the continuity of the link between the orthotopic spleen and the gonad: the continuous and discontinuous forms. In a third of the cases, there are associated congenital malformations and particularly in the continuous forms (44 to 50% of the cases): anomalies of the limbs, micrognathia, microgyria, and hepatic and digestive abnormalities. Cryptorchidism is associated with the continuous form in 31% of cases. The preoperative diagnosis remains difficult because of its morphological and clinical characteristics suggesting a tumor process.

  • An Unconcealed Reservoir: Case Report of Erosion of Inflatable Penile
           Implant Reservoir through the Anus

    • Abstract: Inflatable penile prosthesis (IPP) involves placement of the fluid reservoir into an abdominal or pelvic location. While the space of Retzius (SOR) was the preferred site for many years, the change from open to robotic prostatectomy made this space less desirable due to the violation of the peritoneum with the robotic approach. Other factors like previous abdominal or pelvic surgeries (particularly inguinal hernia repair with mesh) may also require a change in location of the reservoir during IPP placement. In this report, we discuss a previously undescribed result of alternative reservoir placement (ARP) with erosion of the reservoir through the colon and out of the anus in a man with multiple previous abdominal surgeries. Management of this clinical problem is also discussed.

  • Penile Glans Amputation following Circumcision: A Case Report of a Rare

    • Abstract: Circumcision is the most prevalent surgery among men. Like any other surgical intervention, it is associated with several complications. A rare shocking complication is glans amputation which is a urologic emergency. Herein, we present a 4-year-old boy with penile glans amputation following circumcision. The reimplantation was performed in less than two hours. We approximated the ends over a size 4 : 0 catheter. The urethral anastomosis was performed via 6 : 0 Vicryl sutures. Then, we sutured amputated glans in place via Vicryl 4 : 0. We immobilized the penis for a week via bandages used in penile reconstruction surgeries. We also used pentoxifylline to treat glans ischemia after surgery. The patient and his parents did not mention any difficulties or abnormalities while voiding, and the cosmetic result was favorable after three months of follow-up.

  • KRAS Mutation in Serous Borderline Tumor of the Testis: Report of a Case
           and Review of the Literature

    • Abstract: Ovarian-like epithelial tumors of the testis, including serous borderline tumors, are rare entities. We report the case of a 60-year-old man with a left intratesticular mass who had a radical orchidectomy. Histologically, the tumor was identical to the ovarian counterpart showing a well-delineated cystic lesion characterized by intraluminal papillae. The papillae are lined by atypical cuboidal or ciliated cells and are associated with psammoma bodies. The tumor cells express cytokeratin 7 (CK7), cytokeratin 5-6 (CK5-6), cancer antigen 125 (CA125), estrogen (ER), progesterone (PR), Wilm’s tumor gene (WT1), paired box gene 8 (PAX8), Ber-EP4, and epithelial membrane antigen (EMA). The diagnosis of a serous borderline tumor of the testis was proposed. Mutation testing using next-generation sequencing showed a Q61K KRAS gene mutation. To the best of our knowledge, this is the second case report of a serous borderline tumor of the testis with a Q61K KRAS gene mutation.

  • Ureterocalyceal Fistula: A Rare Complication of Laparoscopic Partial

    • Abstract: Background. Postoperative urinary leak is a well-documented complication following partial nephrectomy. It usually presents as persistent discharge from the retroperitoneal drain, nephrocutaneous fistula, urinary collection, systemic manifestations, or abdominal symptoms. Herein, we report for the first time on a case of urinary leak postlaparoscopic partial nephrectomy which did not heal and led to the formation of ureterocalyceal fistula. Case Presentation. A 41-year-old male presented with a coincidental renal mass at the inferiomedial aspect of the right kidney. He underwent laparoscopic partial nephrectomy. On the third postoperative day, he developed fever. CT scan showed minimal urine leak from the tumor site and a JJ stent was inserted. Due to severe bladder symptoms, the stent was removed and a perirenal drain was inserted and removed in few days. He did well initially but in two weeks, he started to develop urinary tract infections. Repeat CT scan showed ongoing urinary leak from the site of the previous surgery. Retrograde pyelography demonstrated a complete UPJ stenosis with an ureterocalyceal fistula. Trial for reanastomosis failed due to severe adhesions and small intrarenal pelvis. An ureterocalyceal anastomosis has to be performed to another calyx. Conclusion. We report for the first time on an ureterocalyceal fistula following laparoscopic partial nephrectomy. This complication might be prevented by a careful dissection of the area close to the ureter or by an insertion of a JJ stent for an adequate time if a ureteric injury is suspected.

  • A Rare Case of Urinary Tract Fungal Ball Leading to Fungemia and Bilateral

    • Abstract: Background. Fungemia due to obstructive urinary tract fungal ball is exceedingly rare. These patients often have multiple predisposing conditions, including diabetes or antimicrobial exposure. While candiduria can be relatively common in this population, urinary tract fungal balls are a rare entity. Hospitalists should be aware of this rare complication in patients presenting with funguria. Case Presentation. We present a case of a 44-year-old male with type II diabetes, chronic hepatitis C secondary to injection drug use, and chronic kidney disease who developed a urinary tract fungal ball leading to fungemia and subsequent bilateral chorioretinitis, additionally complicated by emphysematous cystitis and pyelonephritis. Additional invasive treatment options beyond typical antifungals are often required in the case of urinary tract fungal ball, and in this case, bilateral nephrostomy tubes and micafungin were employed. Hospital course was complicated by C. tropicalis fungemia with subsequent bilateral fungal chorioretinitis on dilated fundus exam. This was effectively treated with cyclogyl and prednisolone drops along with bilateral voriconazole injections. Follow-up imaging and cultures showed resolution of fungemia, urinary tract masses, and chorioretinal infiltrates; however, recurrent polymicrobial UTIs continue to be an issue for this patient. Conclusions. Special multidisciplinary management is required in the treatment of urinary tract fungal balls with subsequent fungemia, including nephrostomy tubes, antifungal irrigation, ureterorenoscopy, and more powerful antifungals such as amphotericin B and 5-flucytosine. This management draws from a myriad of specialties, including urology, infectious disease, and interventional radiology. Additionally, the literature has demonstrated that only approximately half of patients with fungemia receive an ophthalmologic evaluation. Ophthalmologic and urologic cooperation is essential in the case of obstructive uropathy leading to fungemia as the obstructive uropathy must be relieved and these patients should receive a dilated fundus exam.

  • Renal Angiomyolipoma Mimicking a Well-Differentiated Retroperitoneal

    • Abstract: A 37-year-old Burmese woman presented with an incidentally found retroperitoneal fat-containing tumor. The tumor was 9 cm in the longest diameter, surrounding the right kidney, and composed of homogenous adipose tissue with thickened septum-like structures and spotty nonadipose structures, which were enhanced on contrast-enhanced computed tomography and magnetic resonance imaging. The tumor did not show either a beak sign or synchronous angiomyolipoma-like lesion in the kidneys. The tumor had irregular septa, thin blood vessels, and spotty small soft-tissue nodules. The tumor did not contain any heterogeneously enhanced solid lesions suspicious for dedifferentiated liposarcomas. Based on these imaging findings, a clinical diagnosis of a well-differentiated liposarcoma was made. Under the consensus of a multidisciplinary cancer board, she was recommended to undergo core-needle biopsy to confirm the clinical diagnosis. However, she declined to undergo biopsy for financial reasons. She underwent kidney-sparing retroperitoneal tumor resection. Histopathologically, the tumor was an angiomyolipoma with positive immunostaining for HMB45 and Melan A. The present case suggests the importance of core-needle biopsy prior to surgical intervention for retroperitoneal fat-containing tumors.

  • Abnormal Adrenal Mass Presents as Proximal Epithelioid Sarcoma

    • Abstract: Epithelioid sarcoma (ES) is a rare malignant mesenchymal neoplasm that accounts for less than one percent of all soft-tissue sarcomas. Only two cases of ES involving the adrenal gland were found after a literature review. We report a case of an 82-year-old female initially presenting with right flank pain who was subsequently found to have an incidental left adrenal mass on CT imaging. After appropriate diagnostic workup, the patient underwent surgical resection. A diagnosis of ES was made from the histopathological analysis. The characteristic findings of ES are epithelioid cells with rhabdoid morphology and moderate eosinophilic cytoplasm. Immunohistochemical findings are significant for positive staining for epithelial markers, cytokeratins, vimentin, and CD34, and loss of INI-1 stain. Due to the aggressive nature and limited data of ESs, the standard treatment continues to remain wide surgical excision.
