OBJECTIVES To evaluate the efficacy and safety of mini- percutaneous nephrolithotomy (PCNL) in the treatment of large impacted proximal ureteral stones. METHODS We retrospectively reviewed the outcomes of 163 patients who underwent mini-PCNL between January 2006 and August 2010. Mean age was 48.6 years and mean stone size was 18.4 mm. Hydronephrosis and/or hydroureterosis appeared in all pati...


 Background. Kidney stones are one of the three most common cases in urology. The best standard management for kidney with stone burden >20mm is PCNL (percutaneous nephrolithotomy), a minimal invasive method that uses percutaneous access to remove stones. One complications was bleeding which can be caused by several factors , them burden.Objective. look at relationship hemoglobin drop ...

INTRODUCTION Paediatric percutaneous nephrolithotomy (PCNL) has revolutionised the treatment of paediatric nephrolithiasis. Paediatric PCNL has been performed using both adult and paediatric instruments. Stone clearance rates and complications vary according to the technique used and surgeon experience. We present our experience with PCNL using adult instruments and a 28Fr access tract for lar...

OBJECTIVE To compare the efficacy of tubeless percutaneous nephrolithotomy (PCNL) using double-J stent and tubeless PCNL with external ureteral catheter in decreasing post-PCNL complications. METHODS This prospective randomized comparative study includes 148 cases with kidney stones. They were operated by either tubeless PCNL with double-J stent (Group 1) or tubeless with ureteric catheter (G...

OBJECTIVES To assess the feasibility of performing percutaneous nephrolithotomy (PCNL) with the patient supine. Although PCNL with the patient prone is the standard technique for treating large (>2 cm) renal stones including staghorn stones, we evaluated the safety and efficacy of supine PCNL for managing large renal stones, with special attention to evaluating the complications. PATIENTS AND...

BACKGROUND The aim of this study was to evaluate the efficacy of superselective renal artery embolization in patients with bleeding into the urinary system. MATERIAL/METHODS From 2007 to 2012, 20 patients were treated with superselective renal artery embolization for bleeding after percutaneous nephrolithotomy (PCNL), nephron-sparing surgery (NSS), including 1 patient with AVF after PCNL. Dur...

Minimally invasive percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) are both alternatives for PCNL to treat renal calculi. This study is aimed at comparing the stone-free rate (SFR) and other surgery parameters of two approaches for treating upper urinary calculi. We performed this meta-analysis in September 2016 by searching studies about mini-PCNL and RIRS for...

PURPOSE Re-procedure in patients with history of open stone surgery is usually challenging due to the alteration in the retroperitoneal anatomy. The aim of this study was to determine the possible impact of open renal surgery on the efficacy and morbidity of subsequent percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS From March 2009 until September 2010, 120 patients underwent PCNL....

The prevalence of stone disease is increasing in the US. With evolving technology, trends surgical techniques, including ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), and shockwave lithotripsy (SWL), remain unclear. objective this study was to evaluate management a US commercial population. A retrospective analysis conducted using IBM MarketScan Commercial Claims Encounters Database....
