Abstract Introduction: Radical cystectomy with pelvic node dissection remains the standard of care for muscle-invasive bladder carcinoma (MIBC); however, there is a growing interest in bladder preservation alternatives among the elderly population. Guidelines indicate that partial cystectomy (PC) combined with pelvic node dissection (LND) can be considered as an alternative in carefully selected individuals. Using the National Cancer Database, we analyzed the overall survival (OS) between PC with and without LND among octogenarians. Methods: We identified octogenarians with localized muscle-invasive bladder carcinoma (cT2-3N0M0) and urothelial histology who underwent PC with or without LND between 2004 and… More >

Abstract Introduction: When conservative treatments fail, botulinum toxin A (BoNT-A) is an option for refractory idiopathic overactive bladder (OAB). This review evaluates the efficacy, safety, and predictive factors for BoNT-A in this situation. Material and Methods: A literature search up to January 2025 was performed using PubMed, Google Scholar, and Embase to assess efficacy, safety, and predictors of adverse events (AE) related to BoNT-A. The risk of bias was assessed using the Risk of Bias 2 (RoB 2) tool for randomized studies and the Critical Appraisal Skills Programme (CASP) checklist for cohort studies. The quality of the… More >

Abstract Background: Primary renal myoepithelial carcinoma is an exceptionally rare malignancy with limited data on optimal treatment, particularly in metastatic settings. Case Description: In 2020, Shenoy reported a dramatic response in a case of metastatic myoepithelial carcinoma with Ewing sarcoma breakpoint region 1-POU class 5 homeobox 1 (EWSR1-POU5F1) fusion arising from the left kidney using the Ewing Sarcoma vincristine, doxorubicin, cyclophosphamide/ifosfamide, etoposide (VDC/IE) chemotherapy regimen. Ten months post-treatment, the patient showed ~90% reduced disease burden on imaging. Subsequent treatment included consolidation vincristine, cyclophosphamide/ifosfamide, etoposide (VC/IE) chemotherapy, surgical resection of the remnant tumor, and follow-up imaging. Conclusion: The More >

Abstract Background: Transrectal (TR) and transperineal (TP) biopsies are commonly used methods for diagnosing prostate cancer. However, their comparative effectiveness in conjunction with machine learning (ML) techniques remains underexplored. This study aimed to evaluate the predictive accuracy of ML algorithms in detecting prostate cancer using data derived from TR and TP biopsies. Methods: The clinical records of patients who underwent prostate biopsy at King Saud University Medical City and King Faisal Specialist Hospital and Research Centerin Riyadh, Saudi Arabia, between 2018 and 2025 were analyzed. Data were used to train and test ML models, including eXtreme… More >

Abstract Introduction: Distal ureteral obstruction has classically been managed by ureteroneocystostomy (UNC). The feasibility and success of robotic primary ureteroureterostomy (UU) for benign obstruction appears promising with several benefits over UNC but is poorly studied. Robotic repair offers superior visualization and precision, allowing for minimal ureteral dissection. Here we report on our experience and short-term outcomes. Materials and Methods: We identified patients who underwent robotic distal ureteroureterostomy for benign distal ureteral obstruction at our institution from 2020–2024. Etiology, stricture length, and post-operative outcomes were recorded. All patients had renal ultrasound (US), diuretic renography, or cross-sectional imaging within… More >

Abstract Introduction: We examined the pathology and safety outcomes associated with the extent of pelvic lymph node dissection in patients with high-risk prostate cancer undergoing radical prostatectomy. Materials and Methods: We retrospectively identified men with prostate cancer who underwent robot-assisted radical prostatectomy with pelvic lymph node dissection between May 2016 and September 2021. Cases were categorized using Current Procedural Terminology (CPT) codes (38571) for extended lymph node dissection and super-extended lymph node dissection (38572). Using logistic regression, we compared the groups on a number of factors, including recurrence. Results: Super-extended lymph node dissection had significantly higher median… More >

Abstract Aim: The aim of this study was to investigate the factors affecting treatment success in children that got either pyeloplasty or J stent placement in ureteropelvic junction obstruction (UPJO). Patients and Methods: The study comprised 126 patients who either J stent placement or pyeloplasty performed by the same physician for UPJO from 2012 to 2022. The criteria for surgical intervention adhered to the European Association of Urology (EAU) recommendations. Symptomatic patients with verified obstruction, with a split renal function (SRF) over 40%, low-grade hydronephrosis (Society of Fetal Urology grade 2), and an obstructive segment measuring less… More >

Abstract Background: Bladder augmentation is frequently required to manage poorly compliant, low-capacity bladders resulting from posterior urethral valves (PUV). While traditional enterocystoplasty techniques are limited by complications associated with bowel tissue use, ureterocystoplasty presents a favorable alternative in patients with concurrent megaureter. Methods: We describe a novel teapot ureterocystoplasty technique that enhances ureteral vascular preservation by maintaining a 3 cm distal ureteral segment in its detubularized configuration. Postoperative outcomes demonstrated significant improvement, with cystographic bladder capacity increasing from 50 to 180 mL. Renal function stabilized following a transient creatinine elevation to 250 μmol/L. Result and Conclusion: At More >

Abstract Polyorchidism is a rare anomaly of the male urogenital tract characterized by the presence of one or more extra testes. Supernumerary testes can often present with coexistent conditions, including cryptorchidism, inguinal hernia, and torsion. We report a case of a pediatric patient with initial concern for intra-scrotal left testicular torsion on ultrasonography who was ultimately found to have torsion of an intra-abdominal supernumerary testis. He underwent scrotal exploration with bilateral orchiopexy and laparoscopic excision of the torsed gonad. This case highlights a unique presentation of polyorchidism with incongruent descent of an ipsilateral supernumerary testis. More >

Abstract Introduction: Benign prostatic hypertrophy (BPH) is a common condition affecting men later in life, significantly impacting quality of life (QOL). Surgical intervention is often pursued when medical management fails, but patient satisfaction with outcomes varies. Decisional regret can affect perceived success and patient satisfaction post-surgery. This study evaluates the relationship between post-surgical symptoms and decisional regret across BPH procedures. Methods: A prospective, multicenter cohort study included 54 patients undergoing BPH surgery between March 2023 and February 2024. Patients completed the International Prostate Symptom Score-QOL (IPSS-QOL) scale preoperatively and at least three months postoperatively, along with… More >

Abstract Inflatable penile prosthesis (IPP) implantation is the gold standard treatment for patients with erectile dysfunction who are refractory to medical therapy. The standard placement of the reservoir in the space of Retzius (SOR) may be contraindicated in patients with prior pelvic or abdominal surgery due to altered anatomy and increased risk of complications. This has led to the development of alternative ectopic reservoir placement techniques. In this narrative review, we summarize the literature on various ectopic reservoir approaches, including low and high submuscular placements, submuscular techniques with counter incisions or transfascial fixation, midline submuscular placement, More >
