چکیده
BACKGROUND An intravenous urogram (IVU) has traditionally been considered mandatory before treating renal and ureteric stones by extracorporeal shock wave lithotripsy (ESWL). This study was designed to see whether there is a difference in complications and the need for ancillary procedures in patients managed by ESWL for renal and ureteric calculi, according to preoperative imaging technique. METHODS This retrospective study compared 133 patients undergoing ESWL from January 2001 to July 2002. Patients were divided into three groups according to the preoperative imaging technique used: i) IVU; ii) non-contrast enhanced helical computed tomography (UHCT); and iii) ultrasound (US) + X-ray kidney, ureter and bladder (KUB). The groups were matched in terms of age and gender, as well as location, side and size of stones. RESULTS There was no statistically significantly difference for number of ESWL sessions, number of shock waves and use of ancillary procedures between the three groups. The stone-free rate was 98% for the IVU and UHCT groups, and 97% for the US + X-ray KUB group. CONCLUSIONS The complication rate and need for ancillary procedures was comparable across the three groups. Patients imaged by UHCT or US + X-ray KUB prior to ESWL for uncomplicated renal and ureteric stones do not require IVU.

Background and purpose: Extracorporeal shock wave lithotripsy changed the treatment of renal stones. Beacause the widespread usage of ESWL (extra Corporeal shock wave lithotripsy) in the treatment of the Urinary tract stones, the effects of these waves on the surrounding tissues are not compeletly understood and it is the origin of so many studies. Materials and methods: In this prospectiv...

Two hundred and fifty patients with 290 stones presenting to the Department of Urology were treated with the Candela MDL 2000 Laser Lithotripter. Overall stone clearance rate was 95%. The more proximal the calculus the lower the success rate. Ninety eight percent of stones in the lower ureter, 95% of mid ureteric and 91% of upper ureteric stones were cleared. The major complication was perforat...

BACKGROUND Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive treatment of urinary stones which breaks them, by using externally applied, focused, high intensity acoustic pulse, into smaller pieces so that they can pass easily through ureter. Shock wave generation, focusing, coupling and stone localisation by fluoroscope or ultrasound are the basic components of ESWL. ESWL has some ...
