transurethral ureterolithotripsy (tul) is a frequently used procedure in urology departments. many urologists perform tul without antibiotic prophylaxis; however the use of chemoprophylaxis before tul remains a controversial issue in urology. thisstudy was carried out to assess the safety of omitting antibiotic prophylaxis prior to tul. in a prospective randomized clinical trial from january 20...

BACKGROUND AND PURPOSE Endoscopic lithotripsy is often prolonged secondary to the retrograde migration of calculous fragments. Various balloons, baskets, and other devices have been used to prevent this migration. Our purpose is to analyze the effect of the Accordion(®) on stone migration and overall efficiency during lithotripsy. PATIENTS AND METHODS We prospectively evaluated 21 patients wi...

Objectives. We compared outcome and complications after uncomplicated ureteroscopic treatment of distal ureteral calculi with or without the use of ureteral stents. Materials and Methods. 117 patients, prospectively divided into three groups to receive a double j stent (group 1, 42 patients), ureteral stent (group 2, 37 patients), or no stent (group 3, 38 patients), underwent ureteroscopic trea...

A single-board certified urologist with training and experience in anesthesiology was assigned to treat 502 patients (185 with renal stones, 317 with ureteral stones) using the Dornier Compact Delta lithotripter under general or epidural anesthesia. Data were obtained regarding stone location, stone size, shockwave use, stone-free rate, and complications. In all, 502 stones were treated with th...

BACKGROUND Stone retropulsion represents a challenge for intracorporeal lithotripsy of ureteral calculi. The consequences are an increased duration and cost of surgery as well as decreased stone-free rates. The use of additional tools to prevent proximal stone migration entails further costs and risks for ureteral injuries. We present the simple technique of using a coil of the routinely used g...

PURPOSE We have clarified the usefulness of extracorporeal shock wave lithotripsy for patients with ureteral stone in an outpatient clinic. PATIENTS AND METHOD One hundred ten patients with ureteral stone were treated using a small focused piezoelectric lithotriptor (Toshiba ESL-500A). No anesthesia and no associated therapy was applied to all patients. RESULTS Ninety eight patients (89.1%)...

Ureteral stents are one of the most commonly used urologic devices with the purpose of establishing and maintaining ureteral patency. They are also associated with a number of complications including infection, migration, stent-related symptoms, and encrustation, leading to lithiasis. Prolonged stent dwell time is associated with a greater degree of these complications. We present the case of a...

from sep. 1984 to aug. 1990,99 patients were treated for ureteral stone using the urekroscope. in five patients ureteroscopy was repeated for a second stone. in one patient the procedure was diagnostic in nature and in the rest of the patients it had a curative value. in 60 patients the stone was removed by electrohydraulic and basket combination and in25 cases, dilatation alone was enough. rat...

OBJECTIVES To calculate the efficiency quotient (EQ) of the latest mobile Storz Modulith SLX-F2 lithotripter and to identify the factors determining the stone-free rate. METHODS A retrospective review of a prospectively collected database of the first consecutive 533 patients undergoing shock wave lithotripsy (SWL) from June 2009 to February 2010 was performed. A total of 16 patients with rad...

BACKGROUND Animal studies have shown that nicotine affects the peristalsis of the ureter. The aim of the study is to analyze the effect of smoking on spontaneous passage of distal ureteral stones. METHODS 88 patients in whom distal ureteral stone below 10 mm diameter diagnosed with helical computerized tomography enhanced images were reviewed. Patients were grouped as either smokers (n:33) or...
