Abstract:
Extracorporeal shock wave lithotripsy monotherapy was performed in 72 renoureteral units from 66 patients with the Northgate SD-3 lithotriptor using ultrasound stone localization between June 21, and August 25, 1989. Of 72 cases renal stones were 46 cases( 63.9% ) and ureteral stones 26 cases ( 36.1% ). No regional or general anesthesia were necessary but sedatives or analgesics were required in most patients. Among 67 cases who completed extracorporeal shock wave lithotripsy, the success rate of treatment(rate free of calculi plus that of clinically insignificant residual stone fragments) was achieved 100% below 20mm, 87.5% in 21-30mm and 100% over 31mm and the total mean success rate was 97%. 23 cases( 31.9% ) were required auxiliary procedures such as Double-J stent in 14 cases, push up procedures 6 cases and stone basket 3 cases. Poet-lithotripsy complications were transient macroscopic hematuria in 90%, renal colic 20.8%, steinstrasse 13.9%, fever 6.9% and subcapsular hematoma 2.8% and these complications were controlled with conservative management. We suggest that extracorporeal shock wave lithotripsy monotherapy with the Northgate SD-3 lithotriptor was considered to be effective and safe procedure for the initial treatment of urinary stone.
