PURPOSE We analyzed long-term results after percutaneous nephrolithotomy (PCNL) in patients with impaired renal function. PATIENTS AND METHODS Nineteen (6.3%) of 300 patients who underwent PCNL had serum creatinine values above 1.4 mg/dL before surgery and were considered to have impaired renal function. Success rate of operation, recurrence rate, and(More)

PURPOSE We evaluated factors affecting complication rates of ureteroscopy for pediatric ureteral calculi. MATERIALS AND METHODS We retrospectively evaluated 642 children who underwent ureteroscopy at 16 Turkish centers between 2000 and 2010. Semirigid ureteroscopy was used with various calibers to treat 670 ureteral units in 660 sessions. Complications(More)
This study aimed to compare the results of percutaneous nephrolithotomy (PCNL) in patients with impaired renal function (IRF) and normal renal function (NRF). Records of 300 consecutive patients who underwent PCNL from July 2002 to July 2005 were retrospectively reviewed. Nineteen patients (6.3%) had serum creatinine values higher than 1.5 mg/dl before(More)
PURPOSE We analyzed the results of patients who underwent percutaneous nephrolithotomy (PCNL) for management of kidney stone disease under combined spinal-epidural anesthesia and compared surgical parameters and outcomes with a matched control group who underwent PCNL under general anesthesia.
