A 55-year-old woman suffered from right flank pain and had a right giant ureteral stone with hydronephrosis. Ureterolithotomy was performed. The ureteral stone was 11cm long and weighed 45gm.

PURPOSE To evaluate ureteral stenting as a negative predictive factor influencing ureteral stone clearance and to estimate the probability of one-session success in shock wave lithotripsy (SWL) patients with a ureteral stone. MATERIALS AND METHODS We retrospectively reviewed the medical records of 1,651 patients who underwent their first SWL. Among these patients, 680 had a ureteral stone mea...

PURPOSE The purpose of this study was to evaluate the effectiveness of combined ureteroscopic holmium YAG lithotripsy for renal calculi associated with ipsilateral ureteral stones. MATERIALS AND METHODS Between August 2002 and March 2007, retrograde flexible ureteroscopic stone treatment was attempted in 351 cases. Indication for treatment was concurrent symptomatic ureteral stones in 63 pati...

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...

PURPOSE We retrospectively investigated the factors that affect the success of rigid ureteroscopy in the pediatric population for the management of pediatric ureteral stones. PATIENTS AND METHODS We present a retrospective review of 61 consecutive pediatric patients who underwent 66 rigid ureteroscopy procedures for ureteral stone management. The effects of sex, age, stone diameter, stone loc...

OBJECTIVE To derive and validate an objective clinical prediction rule for the presence of uncomplicated ureteral stones in patients eligible for computed tomography (CT). We hypothesized that patients with a high probability of ureteral stones would have a low probability of acutely important alternative findings. DESIGN Retrospective observational derivation cohort; prospective observationa...

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...
