[Clinical experience and results in the treatment of 4402 patients with solitary urinary calculi with the extracorporeal shock wave lithotripter Dornier MFL-500].

OBJECTIVES

To report the series of our Urology Department in the treatment of urinary stone disease with extracorporeal lithotripsy as well as the effectiveness of the Dornier lithotripter MFL-5000.

METHODS

6.602 patients were treated by extracorporeal lithotripsy during 12 years with a total of 17.120 sessions. We examined the treatment outcome of 4.402 patients with a solitary stone, accordingly to stone size and localization.

RESULTS

There were no major complications and only 43 patients experienced "calle litiásica". We treated 4.402 stones. For all stones, independently of size and localization, 2615 (59.4%) were treated in one session, 801 (18.2%) required two sessions, 379 (8.6%) 3 sessions, 213 (4.8%) 4 sessions and 373 (8.4%) 5 or more sessions.

CONCLUSION

The Dornier MFL-5000 lithotripter successfully treated urinary stone disease in patients of all age groups with a retreatment rate and number of sessions per stone similar to other studies, without analgesia or anesthetic procedures, except in the younger age group.
