Abstract Background: Spontaneous rupture of the urinary bladder (SRUB) is a rare condition characterized by bladder rupture without any trauma or previous instrumentation. Diagnosing SRUB can be challenging, leading to potential delays in treatment and significant morbidity. Case description: We present a case of a 75-year-old male with a complex medical history, including atrial fibrillation, systemic lupus erythematosus, antiphospholipid syndrome, and chronic anticoagulation, who developed sudden onset gross hematuria and abdominal pain following bilateral internal iliac artery angioembolization for a spontaneous pelvic hematoma in the setting of supratherapeutic anticoagulation. Extraperitoneal bladder perforation was confirmed by CT cystogram.… More >

Abstract Background: Studies have indicated an association between inflammatory factors (IFs) in the blood and the development of bladder cancer (BC). This study aimed to explore the correlation and clinical significance of IFs with the pathological grading of BC. Methods: A retrospective analysis was conducted on the preoperative blood routine results, postoperative pathological findings, and baseline information of 163 patients. Patients were divided into high-grade and low-grade groups based on pathological grading. Group comparisons and logistic regression analyses were performed using R software version 4.1.3 to explore the relationships between IFs and BC pathological grading. Results: The… More >

Abstract Objectives: Initial treatment for Non-Muscle Invasive Bladder Cancer (NMIBC) has remained mostly unchanged in recent decades. Cryotherapy with CO₂ has been commonly used in medicine for many years. In this study, we present the results of a pre-clinical study aimed at developing a novel cryoablation device to treat superficial low-grade bladder lesions. Methods: Following initial technical and developmental studies, a rigid cryotherapy device was developed. A technical and efficacy assessment was conducted utilizing the porcine model. Overall, twenty-six ablation areas (up to four per animal) were evaluated. Following an initial routine cystoscopy, the bladder irrigation medium… More >

Abstract Objectives: Treatment of patients with lower urinary tract symptoms (LUTS) is often challenging. In men, the origin of LUTS, in particular overactive bladder (OAB) symptoms, is often due to prostate enlargement. However, patients with chronic prostate inflammation (CPI) also frequently experience OAB. Thus far, it is not known if the inflammation per se or concomitant prostate enlargement is the underlying cause of LUTS. Currently, we aim to examine if there is any correlation between CPI and the persistence of OAB symptoms in patients with benign prostate hyperplasia (BPH). Methods: Fifty-one men underwent transurethral resection of… More >

Abstract Background: The COVID-19 pandemic disrupted healthcare systems globally, raising concerns about delayed cancer diagnosis and treatment. In France, transurethral resection of bladder tumors (TURBT) was prioritized in national urology guidelines to ensure the timely management of urothelial carcinoma. This study aimed to assess the impact of care reorganization on tumor staging, recurrence, palliative care, and mortality in bladder cancer patients from the pre-pandemic through late-pandemic periods. Methods: We conducted a retrospective multicenter study including all patients who underwent TURBT with histologically confirmed urothelial carcinoma between April and December of 2019 (pre-pandemic), 2020 (early pandemic), 2021… More >

Abstract While cystolitholapaxy for bladder stones is commonly performed using a transurethral approach, large or complex stone burdens in patients with complex lower urinary tract anatomy may make this inefficient or infeasible. Percutaneous cystolitholapaxy is a safe, effective, minimally invasive alternative for diverse indications, including patients with benign prostatic hyperplasia, urethral stricture disease, closed bladder neck, continent catheterized channel, or other urinary diversion. In this article, we review the indications for and advantages of percutaneous cystolitholapaxy and describe our step-by-step technique for this procedure, including representative imaging and favored equipment. We also discuss preoperative and postoperative More >

Abstract Background: Studies have reported the special value of PANoptosis in cancer, but there is no study on the prognostic and therapeutic effects of PANoptosis in bladder cancer (BLCA). This study aimed to explore the role of PANoptosis in BLCA heterogeneity and its impact on clinical outcomes and immunotherapy response while establishing a robust prognostic model based on PANoptosis-related features. Methods: Gene expression profiles and clinical data were collected from public databases. Spatial heterogeneity of cell death pathways in BLCA was evaluated. Consensus clustering was performed based on identified PANoptosis genes. Cell death pathway scores, molecular, 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 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 Background: Bladder augmentation is often necessary to address poorly compliant and low-capacity bladders which can result from Posterior Urethral Valve. Traditional techniques are limited by complications from using bowel tissue, thus in the setting of a megaureter, ureterocystoplasty is favorable. Methods: We present a case of Teapot ureterocystoplasty, which improves vascular protection of the ureter by leaving the distal 3 cm of the ureter tubularized. Cystograms demonstrated bladder capacity improvement from 50 mL to 180 mL post-operatively. Additionally, creatinine stabilized after a peak of 250 µmol/L. Result and Conclusion: This patient is doing well at 4.5-year More >
