PURPOSE To evaluate the safety and efficacy of spinal anesthesia compared with general anesthesia in patients who underwent percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS One hundred patients with American Society of Anesthesiologists (ASA) score <3 were randomly divided into two groups according to the type of anesthesia. Spinal anesthesia was(More)
OBJECTIVE We present our experience with percutaneous nephrolithotomy (PCNL) for management of large renal calculi in children less than 5 years old, and determine its safety and efficacy when using an adult-size device. PATIENTS AND METHODS Twenty patients younger than 5 years old underwent PCNL between August 2003 and July 2008. After retrograde(More)
PURPOSE A randomized clinical trial was designed to compare the efficacy, success rate and surgical complications of percutaneous nephrolithotomy (PCNL) and laparoscopic pyelolithotomy (LP). MATERIALS AND METHODS Sixty patients with renal pelvic stones larger than 2 cm were randomly divided into two groups of LP and PCNL. All patients were followed up to(More)
BACKGROUND Management of staghorn renal stones is still challenging. We present our experience with laparoscopic anatrophic nephrolithotomy as an alternative option for management of staghorn renal calculi. PATIENTS AND METHODS Twenty-four patients with staghorn renal calculi underwent 25 laparoscopic anatrophic nephrolithtomy procedures. Characteristics(More)
Long-term effects of percutaneous nephrolithotomy (PCNL) on renal function have been evaluated in many studies but there are little data on the renal effects of PCNL immediately after surgery in human patients. The aim of this study was to evaluate estimated glomerular filtration rate (GFR) during the first few days after PCNL. From July to September 2008,(More)
INTRODUCTION Improvement in laparoscopic skills requires practicing, and it is mostly beneficial when live animal models are considered for use. Apart from pelvic trainer, dogs and rabbits are used as the animal models for training laparoscopic surgeries at our center. Every effort is made to keep the animals alive after surgery. MATERIALS AND METHODS(More)
The use of laparoscopic partial nephrectomy (LPN) in patients with tumours >4 cm remains to be further evaluated. We report our experience with LPN in tumours >4 cm compared with tumours ≤4 cm. This is a retrospective study of data from all LPN patients operated from 2003 to 2008. Inclusion criteria were a single organ confined contrast enhancing(More)
BACKGROUND AND OBJECTIVES Major vascular injury is the most devastating complication of laparoscopy, occurring most commonly during the laparoscopic entry phase. Our goal is to report our experience with major vascular injury during laparoscopic entry with closed- and open-access techniques in urologic procedures. METHODS All 5347 patients who underwent(More)
CASE REPORT A 26-year-old woman presented primarily with a transient left flank pain with no accompanying hematuria and urinary symptoms. Ultrasonography showed a 36-mm hypoechoic mass with dimensions in the middle part of her left kidney. Computerized tomography (CT) confirmed an enhanced hypodense mass of 30 × 25 mm in the middle lateral part of the left(More)
OBJECTIVE It was intended to demonstrate the update report of our experience with laparoscopic management of ureteropelvic junction obstruction by division of the aberrant vein and cephalad relocation of the crossing artery in a large group of patients with long-term follow-up. PATIENTS AND METHODS Three hundred and twenty-nine patients were candidate to(More)
