Pak J Med Res Jan ;49(4):127-30.

Objectives: To report our experience with Dornier MPL9000X Lithotripter in terms of safety, efficacy and complications in the management of upper urinary tract stones. Study design: Retrospective study. Study period and place: From 19th April 1998 to 15 August 2007 in the department of Nephrology, Chandka Medical College, Larkana. Patients and Methods: All patients who had renal calculi up to 2.5cm in size were selected for extra corporeal shock wave lithotripsy with Dornier MPL 9000 on the basis of clinical examination, laboratory investigations, X-Ray, intravenous urography and ultrasonography. Simple analgesics /sedation were used before the procedure, except in children where general anesthesia was used. Results: A total of 1965 patients were treated with 3930 sessions (Average 4.1 sessions per patients). Male to female ratio was 1.8:1. Average age of the patients was 35.3 years. The average stone burden was 1.8cm in diameter. Stone did not break in 3.3% cases, where as in 53(2.69%) cases partial fragmentation had occurred. Over all success rate was 84%. About 10.2% cases were lost to follow up. Complications like colic/ pain, transient haematuria and stein Strasse was observed in 33%, 17% and 2.5% respectively. Conclusions: Extra corporeal shock wave lithotripsy for renal calculi was simple, safe and effective in selected group of patients.
