OBJECTIVE: To identify risk factors of perinephric hematoma following extracorporeal shockwave lithotripsy (SWL) for renal calculi through combined analysis of two randomized controlled trials. PATIENTS AND METHODS: This post-hoc analysis included adult patients with solitary renal calculi ranging from 5 to 15 mm, treated with SWL between 2016 and 2022. All patients received cross-sectional imaging (either non-contrast computer tomography scan or magnetic resonance imaging) two days post-SWL to assess the presence and severity of perinephric hematoma...

PURPOSE: Previous studies have demonstrated an association between video-gaming experience (VGE) and improved robotics skills. We aimed to evaluate the initial learning curve for the Ily® robotics system (Sterlab, Sophia Antipolis, France) when applied to flexible ureteroscopy (FU) among both medical students and urology surgeons. METHODS: There were two groups, surgeons and students. An initial questionnaire was completed detailing basic demographics and experience...

BACKGROUND: Undetectable circulating tumor DNA (ctDNA) is an obstacle to performing comprehensive genomic profiling in daily practice to identify genomic alterations. We investigated the associations between clinicopathological factors and undetectable ctDNA using a commercially available comprehensive genomic profiling assay in metastatic prostate cancer. PATIENTS AND METHODS: Patients treated with systemic treatment for metastatic prostate cancer were included...

BACKGROUND: Vesicoureteral reflux (VUR) is a common urologic complication of pediatric kidney transplant, though there is little data on the effect of VUR on histologic graft changes or graft survival. METHODS: All pediatric patients who received a kidney transplant from 2007 to 2020 were selected for retrospective chart review. All participants underwent a voiding cystourethrogram (VCUG) at a 6-month post-transplant. Patients were then categorized into two groups based on vesicoureteral reflux grade: no/low-grade VUR (grades 0-2) and high-grade VUR (grades 3-5)...

OBJECTIVES: This study aims to develop a prognostic model that estimates the post-operative risk of cancer-specific mortality in patients with bladder cancer who underwent radical cystectomy (RC). METHODS: We analyzed the data from patients with bladder cancer who had undergone radical cystectomy without receiving adjuvant chemotherapy across 36 institutions in the Japan Urological Oncology Group. The data were randomly split into training (N = 1348) and validation sets (N = 674) in a 2:1 ratio...

Benign prostatic hyperplasia (BPH) is a chronic disorder that inflicts severe symptoms on middle-aged men. The current study compared the effects of tadalafil and tamsulosin on urological parameters after 3 and 6 months of therapy. A retrospective case-control study was conducted, in which 100 patients with moderately severe BPH were divided into two groups based on their treatment: 50 patients were given tamsulosin 0.4 mg/day and group 50 patients were administered tadalafil 5 mg daily. All patients continued therapy for approximately 6 months, and their urological parameters were assessed at baseline and after 3 and 6 months...

The placement of ureteral stents plays a crucial role in the treatment of ureteral strictures, therefore requiring high material performance standards. In addition, depending on the etiology of ureteral strictures, there are significant differences in the retention time of ureteral stents, thus requiring different degradation rates for the stents. Therefore, it is crucial to develop stent materials with high performance and controllable degradation rates. This study explores the potential of Zn-2Cu-0.5Fe-xMn alloy as a ureteral stent material, utilizing the antibacterial effect of copper ions, the strengthening effect of Fe element on Zn-based alloys, and the accelerated degradation effect of Mn element...

BACKGROUND: Overactive bladder (OAB) syndromes are a vital global issue linked to sleep disturbances and insomnia. This survey explores the relationship between these health burden issues and their risk factors. METHODOLOGY: A survey-based study was conducted among Makkah city citizens' in April 2023. A standardized tool of OAB symptom score and Insomnia Severity Index was used to screen participants. The collected data were statistically analyzed using SPSS. RESULTS: Overall, 529 participants were enrolled in this survey with mean = 37...

OBJECTIVES: Klinefelter syndrome (KF) is a group of chromosomal disorders with at least one extra X chromosome in male individuals that leads to infertility and diminished hair growth in affected males. In this study, we present a case series of 16 nonmosaic KF and an extensive literature review. PATIENTS AND METHODS: This is a retrospective study including 16 nonmosaic Klinefelter Syndrome patients that underwent micro-testicular sperm extraction (m-TESE) at our center between January 2016 and December 2022...

INTRODUCTION: In estimated glomerular filtration rate equations (eGFR), the race multiplier (RM) yields greater eGFR values and may assign less severe chronic kidney disease (CKD) stages to black individuals. When deciding on appropriateness for partial nephrectomy (PN), patients with CKD are often considered a relative or absolute indication. We hypothesize that the eGFR RM may have ramifications for patients being counseled for radical nephrectomy (RN) versus PN to manage their renal tumor...

INTRODUCTION: Office-based procedures under local anesthesia are not a popular and well-accepted concept in pediatric urology except for newborn circumcision. There is limited literature on the utilization of office-based procedures under local anesthesia in pediatric urology. In this study, we present our experience of office-based procedures under local anesthesia from a tertiary center. MATERIALS AND METHODS: This is a retrospective study of the patients who underwent meatotomy and penile adhesion release in the clinic under local anesthesia between January 2017 and August 2022 by a single surgeon in a tertiary center...

INTRODUCTION: Urolithiasis is a common and recurrent condition with a rising global incidence. Stones typically develop in the upper urinary tract, primarily the kidneys. Various factors such as age, gender, diet, fluid intake, climate, occupation, genetics, and metabolic diseases influence stone formation. Stones can vary in size and location, causing obstruction, urine stasis, and complications such as infection. The prevalence of urolithiasis in Saudi Arabia has significantly increased in recent decades, and the study aims to determine the current prevalence and composition trends of urolithiasis, guide treatment and prevention strategies, as well as understand predictors of occurrence and recurrence...

OBJECTIVES: The objectives of this study were to detect whether the use of alpha-blockers in posterior urethral valve (PUV) pediatric patients after valve ablation will improve the persistent obstructive symptoms despite the absence of obstruction and if there are associated side effects of its use. PATIENTS AND: Methods: A prospective, single-blinded randomized study was conducted at the urology department of two hospitals on 50 male children between September 2019 and June 2021 with PUV...

OBJECTIVES: To examine the relationship between clinical patient characteristics and the severity of the disease course in patients hospitalized due to urinary bladder tamponade. The severity was assessed based on hemoglobin (Hgb) levels upon admission, the requirement for red blood cell transfusion (RBCT), and length of hospital stay. MATERIALS AND METHODS: A retrospective analysis was conducted at a single center, involving 75 patients who were hospitalized due to urinary bladder tamponade...

OBJECTIVES: The objective is to compare the safety and efficacy of retrograde intrarenal surgery (RIRS) and ultrasound-guided (US-guided) shock wave lithotripsy (SWL) for the treatment of radiolucent lower pole calculi of 1-2 cm. MATERIALS AND METHODS: This prospective randomized study was performed at our tertiary care urology institute of Benha University Hospitals; cases were randomized either to undergo RIRS (Group A) or US-guided SWL with a triple focus system (Group B)...
