Abstract
During the 4 year peirod from September 1, 1984 through August 31, 1988, a total of 1, 866 patients with calui of the urinary tract (125 patients had bilateral calculi) were subjected to extracorporeal shock wave lithotripsy (ESWL) with a DORNIER HM3 ESWL apparatus. Follow-up was performed factor 1, 056 cases 3 or more months after complete elimination of the calculi, and data were obtained for 343 of them. Lithiasis was found to have recurred after ESWL in 30 cases, with a recurrence rate of 11.1%.
Recurrence was seen in 16.9% of cases with multiple calculi and 6.5% of cases with a single calculus. The difference wa statistically significant. Surgical removed of calculi or spotaneous discharge of calculi had been experienced in 50.0% of the reccurent cases and 27.8% of the non recurrent cases. The difference was also statistically significant. Stone size, stone location and urinary tract infection were unrelated to the recurrence.
