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...

A twenty-eight-year-old female with a history of suprapubic pain and recurrent urinary tract infections presents for urology referral with a kidney, ureter, and bladder radiograph showing a 4.4 cm bladder calculus and 6.5 cm distal left ureteral stone. She underwent effective cystolitholapaxy of the bladder stone. Endourologic attempt (left ureteroscopy) was unsuccessful because of ureteral sto...

From July, 1987 to Oct, 1989 , 104 patients underwent 111 transurethral ureteroscopy procedures at the Air Force Medical Center. All intramural ureters were dilated by flexible metal dilators. The overall success rate for ureteral stone removal was 95.8 per cent. Ureteroscopy was done for evaluation of gross hematuria, strictures, ureteral stent, and ureteral and pyelocalyceal tumors. The ...

PURPOSE Since the holmium:yttrium-aluminum-garnet (Ho:YAG) laser is the flexible lithotrite of choice for ureteral stones, its application to ureteral strictures associated with ureteral calculi is convenient. The results of Ho:YAG laser endoureterotomy in this specific setting have not been defined. We report our experience with Ho:YAG laser endoureterotomy of ureteral strictures associated wi...

PURPOSE For treating proximal ureteral calculi, treatment decision has been known still difficult to choose ureteroscopic lithotripsy (URS) or shockwave lithotripsy. The aims of our study are to identify the possible predictors for necessity of URS and to propose the Gachon University Ureteral Narrowing scoring system (GUUN score) as a helpful predictor. MATERIALS AND METHODS We evaluated 83 ...

30 cases of obstructing proximal ureteral stones at the level of L3-L5 which could not be pushed back into the pelvis and passed by a guide wire under epidural anesthesia, were removed percutaneously with the rigid ureteroscope. Multiple stones in one ureter, bilateral ureteral stones and a ureteral stone of a solitary kidney were removed successfully in one session showing the reliability...

OBJECTIVE To assess the success rates of endoscopic management of upper ureteral stones using semirigid ureterorenoscopy and holmium: YAG laser lithotripters. METHODS A total of 74 patients with an established diagnosis of upper ureteric stone and scheduled for endoscopic ureteral stone treatment were retrospectively evaluated. Failure was defined as the inability to contact or fragment the s...

Urinary colics from calculosis are frequent and intense forms of pain whose current pharmacological treatment remains unsatisfactory. New and more effective drugs are needed to control symptoms and improve stone expulsion. Recent evidence suggested that the Nitric Oxide (NO) / cyclic guanosine monophosphate (cGMP)/phosphodiesterase type 5 (PDE5) system may contribute to ureteral motility influe...
