OBJECTIVE To plan a prospective comparative case-control designed study aiming to compare minipercutaneous (miniperc) and retrograde intrarenal surgery (RIRS) for a renal calculus of size 1-2 cm. PATIENTS AND METHODS A total of 64 cases (32 in each arm) underwent miniperc and RIRS during the study period from March 2009 to April 2011. The primary and(More)
OBJECTIVE To compare micropercutaneous nephrolithotomy (microperc) and retrograde intrarenal surgery (RIRS) for the management of renal calculi <1.5 cm with regard to stone clearance rates and surgical characteristics, complications and postoperative recovery. PATIENTS AND METHODS Seventy patients presenting with renal calculi <1.5 cm were equally(More)
OBJECTIVE To establish the efficacy of early removal of a nephrostomy tube after percutaneous nephrolithotomy (PCNL), to challenge the wisdom of tubeless PCNL, as we hypothesized that it would result in a shorter hospital stay, comparable benefit and safety, while maintaining the option of check nephroscopy ensuring far superior stone clearance. PATIENTS(More)
PURPOSE To our knowledge we report the first technical feasibility and safety study of 1-step percutaneous nephrolithotomy using the previously described 4.85Fr all-seeing needle (PolyDiagnost, Pfaffenhofen, Germany). We defined microperc as modified percutaneous nephrolithotomy in which renal access and percutaneous nephrolithotomy are done in 1 step using(More)
INTRODUCTION The purpose of this study was to compare in a randomized fashion the clinical outcomes following standard laparoscopic and laparoendoscopic single-site (LESS) donor nephrectomies. MATERIALS AND METHODS Fifty voluntary renal donors who met the inclusion and exclusion criteria were randomized to standard laparoscopic (group A) and LESS (group(More)
BACKGROUND AND PURPOSE Large amounts of irrigating fluid are used during percutaneous nephrolithotomy (PCNL). This use may be associated with migrating calculus debris, infection, and fluid absorption. This study evaluated the presence of fluid absorption during PCNL, its clinical and biochemical significance, and maneuvers to reduce it. PATIENTS AND(More)
PURPOSE OF REVIEW To review the recently published literature related to miniperc. RECENT FINDINGS Miniperc has generated lot of enthusiasm in the last few years. Miniperc utilizes tract size of 20 F or less, hence the complication rates are much less. Hematocrit drop is significantly reduced and blood transfusion rates have gone down. Reduced pain and(More)
OBJECTIVE To review the development of the technique of percutaneous nephrolithotomy (PCNL), for ease of learning and development of instrumentation for staghorn calculi at our centre since 1991, and to assess the results and outcomes. PATIENTS AND METHODS We retrospectively analysed the hospital records of 773 patients (632 males and 141 females, 834(More)
BACKGROUND AND PURPOSE Staghorn stone volume and its distribution within the collecting system, "staghorn morphometry," predicts the requirement of tract and stage for percutaneous nephrolithotomy (PCNL) monotherapy. The purpose of the study was to develop a CT urography staghorn morphometry-based prediction algorithm to predict tract(s) and stage(s) for(More)
OBJECTIVES To assess the role of transarterial embolization (TAE) and critically appraise its feasibility and efficacy in the management of non-neoplastic renal hemorrhage. Percutaneous TAE is an effective method for the control of hemorrhage, irrespective of the cause. Injury to the renal artery or its branch, after trauma or during open or percutaneous(More)
