INTRODUCTION: Patients with ileal conduit urinary diversions are at an increased risk of long-term upper urinary tract (UUT) complications, including anastomotic strictures, infections, and urolithiasis. The reconstructed urinary system poses challenges for endoscopic manipulation. We present and describe our dual-center experience in performing retrograde ureteroscopy to treat or diagnose UUT abnormalities in patients with ileal conduit incontinent diversion. PATIENT AND METHODS: We performed a retrospective analysis of medical records for all patients with previous urinary diversion who underwent retrograde ureteroscopic procedures via the ileal loop in our institutions over a 9 year period (between June 2007 and August 2016)...

INTRODUCTION: Urinary stone disease is a major urological condition. Endourologic techniques have influenced the clinical approach and outcomes. Open surgery holds a historic importance in the management of most conditions. However, complex kidney stone burden may be amenable to successful results with open stone surgery. In this article, we report our eighteen cases of complex urinary stone disease who underwent open stone removal. MATERIAL AND METHODS: A total of 1701 patients have undergone surgical treatment for urinary stone disease in our clinic between July 2012 and July 2016, comprising eighteen patients who underwent open stone surgery...

CONTEXT: In an effort to reduce morbidity related to percutaneous nephrolithotomy (PCNL), some investigators have progressively introduced miniaturised approaches. The development of miniaturised nephroscopes facilitated widespread dissemination of these techniques and a significant expansion of the role of PCNL in endourology. OBJECTIVE: To discuss the different techniques comprising modern PCNL and identify the pros and cons of each of them. EVIDENCE ACQUISITION: Data for this review were identified through a search of PubMed, including studies published in the last 20 yr in core clinical journals in English...

INTRODUCTION: The lens of the eye is extremely susceptible to radiation and long-term exposure can induce cataract formation. Our objective was to explore the risk of cataract formation for urologists at our institution. METHODS: A retrospective review of a multi-surgeon database of fluoroscopic cases between 10/2013 to 12/2014 was queried. Procedures were performed by different subspecialties and ranged from stent insertion/ureteroscopy to percutaneous nephrolithotomy...

Background Simulation based technical-skill assessment is a core topic of debate, especially in high-risk environments. After the introduction of the E-BLUS exam for basic laparoscopy, no more technical training/assessment urological protocols have been developed in Europe. Objective We describe the methodology used in the development of the novel Endoscopic Stone Treatment step 1 (EST s1) assessment curriculum. Materials and Methods The "full life cycle curriculum development" template was followed for curriculum development...

Before making a treatment decision for patients presenting with a urethral stricture, following anamnesis and general examinations, appropriate diagnostics are necessary. This includes at least uroflowmetry and cystourethrography and the use of ultrasound and cystoscopy may be of additional help. The curative treatment of a urethral stricture is always an operation. Besides endourological procedures, open surgery for urethral reconstruction is also performed. This article aims to give an overview about the necessary diagnostic measures and the pros and cons of the different operative therapies...

INTRODUCTION: With advances in endourology, open stone surgery for staghorn calculi has markedly diminished. Anatrophic Nephrolithotomy (AN) is performed for complex staghorn stones which cannot be cleared by a reasonable number of Percutaneous Nephrolithotomy (PNL) attempts. AIM: To assess the indications and outcomes of AN in the modern era. MATERIALS AND METHODS: Between April 2008 and July 2015, AN was done in 14 renal units in 13 patients...

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: Current treatment practices within the field of endourology require the routine use of radiation exposure to provide adequate imaging during urologic procedures. One such procedure requiring repeated radiation exposure during treatment is ureteroscopy. We set out to compare estimated fluoroscopic radiation exposures employing fixed table and portable C-arm fluoroscopy. MATERIALS AND METHODS: A cross-sectional dosimetry phantom model was placed supine on both fixed fluoroscopy and standard operating room tables...

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...
