INTRODUCTION Renal artery pseudoaneurysms may arise as a complication of percutaneous nephrolithotomy (PCNL). Prompt recognition and treatment is essential to arrest haemorrhage which may be life threatening. CLINICAL PICTURE A patient with chronic aortic dissection and malrotated right kidney underwent PCNL for right renal calculus. He developed delayed gross haematuria. TREATMENT Angiogra...

OBJECTIVE To compare the outcome of treatment planning using multislice computed tomography (CT) or intravenous urography (IVU) for supine percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS The study included 60 patients with renal stones, all treated by supine PCNL, between March 2011 and October 2012. The patients were divided randomly into two equal groups; in group 1 30 patients ha...

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...

OBJECTIVE From the trainers' perspective percutaneous nephrolithotomy (PCNL) is one of the most challenging endourological procedures. In this review we examine the problems arising when training residents in PCNL, and how to facilitate this process. METHODS The recommendations are derived from discussions and consensus during the First European Urolithiasis Society (EULIS) meeting held in Lo...

OBJECTIVES To present the chronological development of the different positions described for percutaneous nephrolithotomy (PCNL), in an attempt to identify the reasons for their development and to highlight their specific advantages and disadvantages. METHODS Previous reports were identified by a non-systematic search of Medline and Scopus. RESULTS The classic prone position for PCNL was fi...

This article addresses the respective roles of shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), ureteroscopy (URS), open surgery and laparoscopy as they pertain to the management of lower pole calculi, an area of ongoing controversy. Lower pole stones that are symptomatic, locally obstructing, infection related, or increasing in size require intervention. Smaller, asymptomatic...

INTRODUCTION Percutaneous nephrolithotomy (PCNL) can involve establishing more than one access into the urinary collecting system. The present study examined whether multiple percutaneous accesses results in a more severe reduction in renal function than that after single-percutaneous access. METHODS Adult female pigs were anesthetized, and percutaneous access to the left urinary collecting s...

CT-guided percutaneous renal access has been described as a safe and effective access technique in patients with complex anatomy, including ectopic kidney, retrorenal colon, spinal dysraphism, hepatomegaly, and splenomegaly. In comparison to conventional intraoperative fluoroscopic-guided access, CT imaging allows for delineation of surrounding structures that are at risk for injury during perc...

Received January 2010 Accepted February 2010 INTRODUCTION Percutaneous renal procedures have become an established approach for diagnosis and treatment of a number of renal pathologic lesions. Hemorrhage and vascular lesions are the most serious complications. The reported incidence of postoperative hemorrhage requiring selective angio-embolization for bleeding control is 1.2%.(1) Delayed bleed...
