BACKGROUND: Success rates in endourological procedures, notably percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS), have demonstrated suboptimal outcomes, leading to more reinterventions and radiation exposure. Recently, the use of intraoperative computed tomography (ICT) scans has been hypothesized as a promising solution for improving outcomes in endourology procedures. With this considered, we conducted a comprehensive systematic review and meta-analysis encompassing all available studies that evaluate the impact of the use of intraoperative CT scans on surgical outcomes compared to conventional fluoroscopic-guided procedures...

Lower urinary tract foreign bodies are often reported but the underlying causes remain intriguing, ranging from unconventional practices to medical interventions. This condition predominantly affects young males and presentations are varied from asymptomatic, lower urinary tract symptoms to acute obstructive renal failure. We report a case of a 48-year-old male presented with lower urinary tract symptoms and obstructive renal failure. Imaging revealed multiple foreign bodies in the pelvic cavity, suggestive of vesical, and urethral lithiasis...

INTRODUCTION: Establishing percutaneous renal access is the key initial step to PCNL; however, learning the technique during surgery for trainees is complicated by the number of approaches used to gain access, limited completion time during a breath hold and attempt to minimize the number of passes through a kidney. There are many training models for percutaneous access commercially available all with their respective limitations. Our objective was to develop a low cost, high fidelity percutaneous access training model that addresses existing limitations and can be used with both ultrasound and fluoroscopy guidance...

Objective To perform a systematic review to assess the incidence of reoperation rate for residual/regrowth adenoma after transurethral surgeries for benign prostatic enlargement. Materials and Methods A systematic literature search was performed on 12th November 2023 using Cochrane Central Register of Controlled Trials, PubMed, and Scopus. We only included randomized studies comparing monopolar(M)/bipolar(B) TURP vs Ablation vs Enucleation procedures. Incidence of reoperation was assessed using the Cochran-Mantel-Haenszel Method and reported as risk ratio (RR), 95% confidence interval (CI), and p-values...

OBJECTIVE: To evaluate the long-term functional and oncological outcomes following robotic partial (RAPN) and radical nephrectomy (RARN). MATERIALS AND METHODS: A retrospective review was performed on 1816 patients who underwent RAPN and RARN at our institution between January 2006 and January 2018. Patients with long-term follow-ups of at least 5 years were selected. Exclusion criteria included patients with a previous history of partial or radical nephrectomy, known genetic mutations, and whose procedures were performed for benign indications Statistical analysis was performed with results as presented...

Introduction Artificial intelligence tools such as the large language models (LLMs) Bard and ChatGPT have generated significant research interest. Utilization of these LLMs to study epidemiology of a target population could benefit urologists. We investigated whether Bard and ChatGPT can perform a large-scale calculation of the incidence and prevalence of kidney stone disease. Materials and Methods We obtained reference values from two published studies which used the National Health and Nutrition Examination Survey (NHANES) database to calculate the prevalence and incidence of kidney stone disease...

Introduction Ureteral stents can cause significant patient discomfort, yet the temporal dynamics and impact on activities remain poorly characterized. We employed an automated tool to collect daily ecological momentary assessments (EMA) regarding pain and ability to work following ureteroscopy with stenting. Our aim was to assess feasability, and better characterize the postoperative patient experience. Methods As an exploratory endpoint within an ongoing clinical trial, patients undergoing ureteroscopy with stenting were asked to complete daily EMAs for 10 days postoperatively, or until the stent was removed...

OBJECTIVE: To assess the outcomes of redo laparoscopic pyeloplasty (RLP) in pediatric patients with recurrent ureteropelvic junction obstruction (UPJO) in contrast to redo open pyeloplasty (ROP). Additionally, evaluate the feasibility and efficacy of RLP as a treatment modality for recurrent UPJO in children. MATERIALS AND METHODS: The data of 44 patients from March 2012 to March 2022 who underwent redo pyeloplasty were retrospectively reviewed. In Group RLP, the children underwent RLP, while ROP was attempted in Group ROP...

INTRODUCTION AND OBJECTIVE: Renal transplantation is the treatment for end stage renal disease that offers better quality of life and survival. Among the possible complications that might affect allografts, urolithiasis might have severe consequences, causing acute kidney injury(AKI) or septic events in immunocompromised patients. Allograft stones might be treated with percutaneous nephrolithotomy(PCNL). The aim of this Cochrane style review was to assess the safety and efficacy of PCNL in patients with renal transplant...

UNLABELLED:   Abstract Purpose: We herein describe the superficial preprostatic vein anatomy and determine its relationship with the accessory pudendal artery. MATERIALS AND METHODS: We reviewed 500 patients with localized prostate cancer who underwent conventional robot-assisted radical prostatectomy between April 2019 and March 2023 at our institution. Superficial preprostatic vein was defined as "any vein coming from the space between the puboprostatic ligaments and running within the retropubic adipose tissue anterior to the prostate toward the vesical venous plexus or pelvic side wall...
