Extracorporeal shock wave lithotripsy; Efficacy of in situ echoguidance in upper and lower ureteral calculi

ABSTRACT

amanullah7860@yahoo.com. To assess efficacy of ESWL as a single modality in upper and lower ureteric calculi. department of Nephro-Urology Chandka Medical College Hospital, Larkana. January 2003 to April 2006. 62 patients underwent ESWL. Upper and lower ureteral calculi were treated by using Dornier MPL-9000 Lithotripter with ultrasound localization. Among 62 cases 56[90.3%] patients had upper ureteric calculi, whereas 06[9.7%] patients had lower ureteric calculi. Size of stones ranged from 0.5 mm to 18mm having mean size of 10mm. All patients were followed for period of 6 weeks. Of these 62 patients 58 patients were stone free at the end of 2 weeks follow up. In 2 cases stones failed to fragment, where as 2 cases failed to attend out patient department for follow up. This study concluded that in situ echoguided ESWL was effective modality of treatment for upper and lower ureteric stones. Localization of ureteric stones with ultrasound has the advantage of elimination of radiation exposure to the patient and lithotripsy team
