PURPOSE To correlate the presence of secondary signs of non-enhanced computed tomography (NECT) in renal units harboring ureteral calculi with intraoperative findings and treatment outcome after holmium:yttrium-aluminum-garnet laser (Ho:YAG) ureterolithotripsy. SUBJECTS AND METHODS Two-hundred patients were prospectively included after ureteral calculi were detected on NECT. All patients unde...

OBJECTIVES We conducted a retrospective study to evaluate the efficacy and outcome of shock wave lithotripsy versus semirigid ureteroscopy in the management of the proximal ureteral stones of diameter exceeding 15 mm. METHODS During the 2009-2014 study period, 147 patients presenting with the proximal ureteral stones exceeding 15 mm in diameter were treated. Both shock wave lithotripsy and ur...

PURPOSE To evaluate the hypothesis that prophylactic insertion of Double-J stents after uncomplicated transurethral lithotripsy (TUL) can decrease the number of episodes of renal colic and their intensity in patients with recurrent ureteral stones (those with three or more episodes of stone formation). PATIENTS AND METHODS During a prospective randomized clinical trial from May 1999 to Januar...

Treatment of ureteral calculi has dramatically changed over time. Open surgery was the method of choice before the 80s, however, two events strongly influenced the management of ureteral lithiasis: the development of rigid ureteroscopy and the application of shock waves. Since then, many papers have been published to assess the efficacy of each technique. They take into account several endpoint...

PURPOSE Extracorporeal Shock Wave Lithotripsy (ESWL) has shown successful outcomes for ureteral stones. We investigated predictive factors for failure of ESWL for treating ureteral stones. MATERIALS AND METHODS A total of 153 patients who underwent ESWL between July 2006 and July 2009 for ureteral stones diagnosed by non-enhanced spiral computed tomography were divided into two groups: (group...

To evaluate the impact of ureteral stenting history to the outcomes of extracorporeal shockwave lithotripsy, we retrospectively analysed patients who underwent shockwave lithotripsy with Dornier Gemini lithotripter between September 2010 and August 2012. Forty seven patients (group A) who had a double J stent which was removed just before the procedure were matched-paired with another 47 patien...

INTRODUCTION The AUA/EAU Ureteral Stones Guideline Panel reported that the stone free rate for the proximal ureteral stones is around 81% when treated by either SWL or ureteroscopy (URS).Complication rates, most notably ureteral perforation and long-term complications of URS such as stricture formation rates, have been reduced to < 5%. Moreover, impacted ureteral calculi are more difficult to f...

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 determine the efficiency of slow delivery rate of shockwaves (SW) on stone fragmentation and treatment outcomes in patients with renal and ureteral calculi. PATIENTS AND METHOD Using the Siemens Lithostar Multiline, we treated 843 patients (229 renal and 614 ureteral stones) at a fast delivery rate (120 SW/min, between October 2003 and August 2006), 448 patients (139 renal and 309 ...

Objective: To assess the efficacy and safety of extracorporeal shock wave lithotripsy or pneumatic ureteroscopic lithotripsy for lower ureteral stones therapy, we sought to identify and summarize randomized controlled trials that were used to treat distal ureteral stone. Methods: Eligible studies were identified from electronic databases. Database search, quality assessment, and data extraction...
