OBJECTIVE: The aim of this study was to report the functional outcome after endoscopic management of neobladder complications. MATERIALS AND METHODS: Out of 197 patients who underwent radical cystectomy and orthotopic ileal neobladder reconstruction between 2007 and 2013, 30 patients with delayed postoperative complications were enrolled in this study. Complications were in the form of: eight patients with outflow obstruction, 12 with ureteroenteric stricture, nine with neobladder calculi and one with an isolated recurrent papillary tumor inside the neobladder...

OBJECTIVE: This study compared the effect of endourological procedures with or without the Amplatz sheath (AS) on cystolithotripsy. METHODS: We retrospectively analysed 18 patients who underwent treatment for bladder stone over 30 mm. This study consisted of two groups, namely, patients who underwent cystolithotripsy with an AS (AS group) and those who underwent standard procedure without an AS (SP group). The stone-free rate, total energy used for operation, operation time, days of admission after operation, and complication of both groups were compared...

INTRODUCTION: Fluoroscopy is widely used during endourologic procedures and is associated with treatment required radiation exposure. Our objective was to estimate patient radiation exposure during fluoroscopy with either a fixed table or portable C-arm using a validated anthropomorphic adult male model. MATERIALS AND METHODS: A validated male anthropomorphic model was placed supine on both a cystoscopy operating room table and a fixed fluoroscopy table unit. Metal oxide semiconductor field effect transistor dosimeters were placed at 20 organ-specific locations in the model to measure organ specific dosages...

BACKGROUND: Almost all endourologic procedures use fluoroscopic imaging in some steps, which exposes both the patient and the surgical team to considerable amounts of radiation. Primary reports on results of a simple direct visual endoscopic access sheath placement technique which does not use fluoroscopy at all are presented. MATERIAL AND METHODS: First a semi-rigid ureteroscopy was carried out up to the renal pelvis, then the access sheath (36 cm, 11/13 Fr) without the obturator was placed over a 7...

REVIEW
Nicholas R Rocco, Jack M Zuckerman
Postprostatectomy vesicourethral anastomotic stenosis (VUAS) remains a challenging problem for both patient and urologist. Improved surgical techniques and perioperative identification and treatment of risk factors has led to a decline over the last several decades. High-level evidence to guide management is lacking, primarily relying on small retrospective studies and expert opinion. Endourologic therapies, including dilation and transurethral incision or resection with or without adjunct injection of scar modulators is considered first-line management...

Background: The use of ureteroscopy in the management of urolithiasis is well established. Ureteral avulsion is a rare but challenging complication of the procedure. Postureteral injury strictures are a common result of such injuries and are typically managed with reconstructive surgery or endoscopically with polymer stent. This case represents the first effective management of ureteral avulsion and subsequent ureteral stricture using a Memokath ureteral stent. Case Presentation: A 54-year-old gentleman presented to the Department of Urology with right loin pain as a result of right renal calculi, previously treated with extracorporeal shockwave lithotripsy...

PURPOSE: To compare intra- and post-operative outcomes of endourological live surgical demonstrations (LSDs) and routine surgical practice (RSP) for urinary stones. METHODS: Consecutive ureterorenoscopic (URS) and percutaneous (PNL) urinary stone procedures over a 5-year period were reviewed. Procedures were divided into LSDs and RSP. Differences between the groups were separately analysed for URS and PNL. Primary outcomes included intra- and post-operative complication rates and grades...

Introduction: Following kidney transplantation, persistent cases of obstructive uropathy from neoureteral stenosis, at the reimplantation site, may require management with permanent, long-term Double-J stenting, following failed open surgical and minimally invasive procedures. We report our experience of the use of Cook Resonance(®) metallic ureteral stent to manage such cases endourologically. Materials and Methods: Medium-term follow-up of two cases requiring long-term ureteral stenting. Medical records, operative details, and radiologic data were reviewed...

INTRODUCTION: Supine percutaneous nephrolithotomy (PCNL) has become increasingly widespread during the last 2 decades. The aim of this study was to analyze the transition from prone to mainly supine PCNL in 2 endourologic centers. MATERIAL AND METHODS: We retrospectively analyzed data on 214 consecutive supine PCNLs divided into the first (2011-2013) and last (2014-2016) 3 years of this study. The first 27 cases were also included in a randomized controlled trial (RCT) by comparison with 24 prone PCNLs...

BACKGROUND: Double-J stents (DJSs) are widely used in urology practice, and removal of these stents can sometimes be forgotten. AIMS: We aimed in this study to investigate whether indwelling time of DJS can predict which treatment modality is required for removal of the stent from the body. STUDY DESIGN: A multicenter, retrospective observational study. METHODS: The data of 57 patients who were treated for forgotten ureteral stents between January 2007 and December 2014 were evaluated retrospectively...

Bilateral obstructing ureteric calculi is a rare cause of acute renal failure. Although urolithiasis in later pregnancy is not uncommon, the development of bilateral obstruction secondary to ureteric calculi in the first trimester is rare and poses difficulty to diagnosis and management. Symptoms of diseases and physiological changes associated with pregnancy can obscure diagnosis of urolithiasis and obstructive uropathy. Advances in minimally invasive endourology afford intervention with reduced risk to fetal health...

BACKGROUND: Percutaneous nephrolithotomy remains the standard of care for kidney stones larger than 2cm. Therefore, setting a prognosis for complete stone resolution through this method is essential. The prognostic tools available have limited prediction.

PURPOSE OF REVIEW: Simulation training for stone surgery is now increasingly used as part of training curricula worldwide. A combination of low and high fidelity simulators has been used with varying degrees of 'realism' provided by them. In this review, we discuss low and high fidelity simulators used for ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) stone procedures with their advantages, disadvantages and future direction for endourological simulation surgery. The final goal will be to understand whether or not 'realism' has to be considered as a critical element in simulation for this field...
