Aim. Sonography has been brought in percutaneous nephrolithotripsy (PCNL) as an adjunct to or substitute for X-ray to restrict radiation exposure. This study was designed to investigate the possible predictors for the success of the solo sonographically guided PCNL. Methods. 148 consecutive cases were prospectively enrolled. All steps of PCNL were performed solely with sonography guidance under...

OBJECTIVE To compare the efficacy of conventional Percutaneous Nephrolithotomy (PCNL) with two of its modified procedures. METHODS A randomized controlled trial, was performed on 60 patients undergoing PCNL. Cases of renal stone regardless of stone size and configuration, having pre-operative negative urine culture, no coagulopathy, and no visible residual stone in intra-operative fluoroscopy...

OBJECTIVES To review reports focusing on the surgical treatment of staghorn stones in children, as despite all the improvements in the surgical treatment of paediatric urolithiasis the management of staghorn calculi still represents a challenging problem in urology practice. METHODS To evaluate current knowledge about treating staghorn calculi in children, we searched PubMed for relevant arti...

PURPOSE To evaluate the effect of 'Bernoulli maneuver' (bringing the access sheath to horizontal plane) on operative time and stone free rates in patients undergoing mini-percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS All consecutive patients with a solitary kidney stone undergoing a mini-PCNL between 2015 and 2016 were included into this study. Patients were randomized either to ...

PURPOSE The traditional prone positioning of percutaneous nephrolithotomy (PCNL) is associated with various anesthetic and logistic difficulties. We aimed to compare the surgical outcomes of PCNLs performed using our modified supine position with those performed in the standard prone position. MATERIALS AND METHODS A prospective group of 236 renal units (224 patients) undergoing PCNL were inc...

PURPOSE To evaluate the percutaneous access outcomes and complications following percutaneous nephrolithotomy (PCNL) that was obtained by sonographer or urologist at a single academic institution. MATERIAL AND METHODS A retrospective chart review of 259 patients who underwent PCNL was performed. Patients were stratified according to percutaneous access by sonographer (group 1) or urologist (g...

PURPOSE To report our experience of percutaneous nephrolithotomy (PCNL) in patients who were treated previously with open stone surgery. PATIENTS AND METHODS Sixty-six patients with a history of open stone surgery (group 1) were compared with 90 patients without previous surgical intervention (group 2). Both groups were almost similar in demographic profile (age, sex, laterality, stone burden...

OBJECTIVE To investigate the safety and efficacy of extracorporeal shock wave lithotripsy (ESWL) combined with percutaneous nephrolithotomy (PCNL) for treatment of complex renal calculus. PATIENTS AND METHODS Seventy-eight patients diagnosed with complex renal calculus and who accepted treatment in our hospital were consecutively selected. Patients were divided randomly into the observation g...

OBJECTIVES Percutaneous nephrolithotomy (PCNL) is the standard management for large and/or complex urolithiasis, but the standard patient position for PCNL is undecided. With the patient prone PCNL has several drawbacks, while when supine, as described previously, PCNL has mechanical limitations. We describe a modification that aims to overcome these limitations and provide easy access comparab...

OBJECTIVES To determine the percutaneous nephrolithotomy (PCNL) effects on the tissues using the quantification of inflammatory mediators, and to assess their impact on the development of postoperative complications. PATIENTS AND METHODS Prospective observational non-randomized study on 40 patients underwent to PCNL. 50 patients with kidney stone who were treated by extracorporeal shock wave ...
