BACKGROUND AND PURPOSE Ureteroscopy is nowadays one of the techniques most widely used for upper urinary- tract pathology. Our goal is to describe its complications in a large series of patients. PATIENTS AND METHODS Between June 1994 and February 2005, 2436 patients aged 5 to 87 years underwent retrograde ureteroscopy (2735 procedures) under video and fluoroscopic assistance. We used semirig...

INTRODUCTION The aim of this study was to evaluate the treatment of upper ureteral calculi with extracorporeal shock wave lithotripsy (SWL) in the supine and prone positions. MATERIALS AND METHODS A total of 68 patients with upper ureteral calculi underwent SWL. In 35 patients, the procedure was performed in the supine position (group 1), while in the 33 remainders, it was performed in the pr...

PURPOSE To evaluate the distribution of ureteral stones and to determine their characteristics and expulsion rate based on their location. MATERIALS AND METHODS We retrospectively reviewed computed tomography (CT) findings of 246 patients who visited our Emergency Department (ED) for renal colic caused by unilateral ureteral stones between January 2013 and April 2014. Histograms were construc...

The purpose of this study was to define factors that have a significant impact on the stone-free rate after ESWL. Methods: A total of 417 patients harboring renal or ureteral stones underwent extracorporeal shock wave lithotripsy (ESWL) between October 2008 and July 2012. Eighty five patients were lost on follow up. The remaining (n = 332). All patients were >18 yr of age. Siemens and SLX-F2 el...

INTRODUCTION The aim of this study was to identify predictive factors of success following a single-session of shock wave lithotripsy (SWL) at 3 weeks of follow-up in our center. MATERIAL AND METHODS The medical records of 116 patients with solitary urinary calculi who underwent single-session SWL in our department between October 2007 and August 2009 were reviewed. All preoperative unenhance...

PURPOSE The aim of this study was to evaluate whether long-term, postoperative ureteral stenting is necessary after ureteroscopic removal of stones (URS) during an uncomplicated surgical procedure. MATERIALS AND METHODS We prospectively examined 54 patients who underwent URS for lower ureteral stones from February 2010 to October 2010. Inclusion criteria were a stone less than 10 mm in diamet...

56 percutaneous nephrostomies were evaluated in 50 patients, with a malignant underlying factor in 32 and benign conditions in 24. The clinical indication was decompression for supravesical obstruction with or without azotemia in the majority of cases. Less common indications were management of ureteral fistula, ureteral stricture dilatation, and pelvic stone extraction. Serious complicati...

PURPOSE The treatment of urinary tract stones in obese patients may differ from the treatment of non-obese patients and their success rate varies. Our objective was to compare ureteroscopic treatment outcomes of ureteral and renal stones, stratified for stone size and location, between overweight, obese and non-obese patients. MATERIALS AND METHODS Charts were reviewed for 500 consecutive pat...

Introduction Our aim was to contribute a study that includes a higher patient population to the limited number of studies comparing tamsulosin and silodosin in the treatment of distal ureteral stones. Material and methods Patients who presented with renal colic to the urology emergency clinic and were diagnosed with ureteral stones and followed-up with conservative treatment between January 201...

OBJECTIVE To perform a prospective randomized trial comparing the efficacy and safety of percutaneous nephrolithotomy (PCNL) in the prone and modified supine positions. METHODS Between August 2010 and August 2011, 102 patients with renal calculi and 20 patients with ureteral calculi were randomized to undergo fluoroscopy and ultrasound-guided PCNL procedures in the prone or modified supine po...
