Extracorporeal shock wave lithotripsy (ESWL) for urinary tract stones using Dornier MFL 5000, performed by the technician.

As the only lithotripsy centre at a University Hospital in the most crowded city of Turkey, we have a big number of patients with urinary stones. Between April 1990 and August 1993, 2680 sessions of treatment were done to 1257 renal units. Our study reveals that the results obtained by the performance of an experienced technician are just as reliable as those obtained by an experienced urologist.
