OBJECTIVES To compare extracorporeal shock-wave lithotripsy (ESWL) with endoscopic lithotripsy to establish the more efficacious and cost-effective treatment for ureteral calculi. METHODS The records of 112 patients with primary ureteral calculi treated at one center with either ESWL or endoscopic lithotripsy were retrospectively reviewed. Follow-up data at 1 and 3 months were obtained in all...

Thirty patients (16 men and 14 women) with cystine urinary stones were treated by extracorporeal shock wave lithotripsy (Dormer HM-3) from December 1984 through October 1989. The average patient age was 35.2 years with a range of 14 to 59 years. Seventy per cent of these subjects had had previous open surgical operations for stones. The cases consisted of 7 ureteral stones and 37 renal stones, ...

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...

Background: Urinary calculi have serious implications in urology. Lower ureteral stones can cause obstructive uropathy and subsequent deterioration of renal function. Because the patient’s symptoms stone size do not predict loss function because there is no clear time threshold for irreversible damage, treatment should be strongly considered any patient with stones. In this study we are compari...

For midureteral and distal-ureteral tumors not amenable to endoscopic resection, distal ureterectomy with ureteral reimplantation is a treatment option. When ureteral length is insufficient for direct reimplantation, additional length can be gained with either a psoas hitch or a Boari flap. We describe our technique for robot-assisted laparoscopic distal ureterectomy and ureteral reimplantation...

PURPOSE This retrospective study evaluated the unenhanced multi-detector computed tomography (MDCT) findings of urinary system calculi and the secondary signs associated with ureteral stones in children. MATERIALS AND METHODS The study included 87 children (54 boys, 32 girls) with a mean age of 89 months (range: 5 months to 16 years) who were referred to us from various departments and were e...

Urolithiasis can result as a complication of urinary diversión, favored by urinary stasis, intestinal mucus, urinary tract bacteriuria, the metabolic derangements and the presence of foreign bodies. We present a 52- year-old male who underwent radical cystectomy with construction of a Bricker uretero-ileostomy. 5 years later he was found with a forgotten ureteral stent, a 6 cm calculi occupying...
