From January 1985 till June 1989, 222 patients with ureteral stones, underwent ESWL treatment. 109 patients were treated with the original Dornier HM3 under general or epidural anaesthesia and 113 patients were treated with the modified Dornier HM3 under anglosedation. 156 stones were in the upper ureter, 15 in the middle ureter, 51 in the lower ureter. We performed a total of 269 ESWL treatments. Out of 109 patients treated with the original HM3 and 113 patients treated by the modified HM3 12 (11%) and 28 (24.7%) needed, respectively, two or more ESWL sessions. In 89.9% and 88.5% of the patients, respectively, has been performed an ureteral manipulation before the treatment to push up or to localize the stone. The treatment was unsuccessful in 10 patients of whom 3 underwent anterograde lithotripsy by percutaneous access, 4 transureteral lithotripsy and 3 surgery. At three months the percentage of patients stone free was as follows: original HM3 patients 88% modified HM3 patients 92.9%. The extracorporeal lithotripsy is now-day the treatment of choice for the ureteral stone without any limitation, due to the stone localisation. The clinical use of modified HM3 on ureteral stones didn't low our success rate, but increased the shock wave out of session.
