collecting system. Early in one’s experience, a catheterized approach may be beneficial for maximizing successful access with minimal complications. Once a level of comfort with percutaneous anatomy is achieved, a noncatheterized approach may be a natural evolution to performing percutaneous nephrolithotomy. A larger randomized study would assist in determining the value of pre-procedure cathet...

PURPOSE The cost-effectiveness of shock wave lithotripsy monotherapy, percutaneous nephrolithotomy and combined sandwich therapy in the treatment of staghorn calculi was examined. MATERIALS AND METHODS The cost-effective index, which estimates the average cost of making 1 patient stone-free, was computed for the various treatment options. Data for effectiveness of each therapy were used as av...

INTRODUCTION Intrarenal pseudoaneurysm is a rare, yet clinically significant, complication of percutaneous nephrolithotomy. A high index of clinical suspicion is necessary in order to recognize pseudoaneurysm as the cause of delayed bleeding after percutaneous nephrolithotomy and angiography confirms the diagnosis which allows endovascular management. CASE PRESENTATION We present a case of a ...

PURPOSE To evaluate the clinical value of computed tomography angiography (CTA) in reducing the risk of hemorrhage associated with mini-percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS A total of 158 patients with renal or ureter stones who had undergone mini-percutaneous nephrolithotomy were retrospectively enrolled into this study from May of 2011 to April of 2014. Group 1 (65 pat...

Background: Although percutaneous nephrolithotomy is most commonly performed with fluoroscopic access, yet, phobia and risks of radiation exposure are 2 important dilemmas. Herein the feasibility of flank position ultrasound guided percutaneous nephrolithotomy for management of renal stones was assessed. Methods: Between September 2012 and June 2016, 250 cases (134 males and 116 females) with r...

A JJ stent is inserted antegradely after percutaneous renal procedures like percutaneous nephrolithotomy (PCNL) for renal calculus disease, and for endopyelotomy for pelvi-ureteric junction obstruction. We describe a technique for antegrade stent insertion after PCNL.

Abstract Background Renal stones are a prevalent urological disorder with various treatment options, including minimally invasive techniques such as Standard-PCNL (S-PCNL) and Mini-percutaneous nephrolithotomy (M-PCNL). This study aims to compare the efficacy safety outcomes of M-PCNL S-PCNL for managing renal calculi. Methods randomized enrolled 60 patients stones, comparing (Group A) B) proce...

OBJECTIVES To assess the implications of different nephrolithometry scoring systems (NLSS) on clinical practice of endourologists to predict stone-free status (SFS) after percutaneous nephrolithotomy (PCNL). METHODS A web-based survey was sent to members of the Endourological Society. Demographic and practice pattern data were collected. Multiple-choice and open-ended questions were used to a...
