Extracorporeal shock wave lithotripsy was performed in 231 patients for 13 months with Dornier MPL 9000 lithotriptor. The 231 patients had renal ( 48.9%) or ureteral (51.1%) stones varying from 0.6 to 4.4cm (mean 1.2cm) in size. Among 231 patients, 184 patients (79.7%) completed the treatment with 1 session and the number of treatment sessions increased in larger stones and in situ impacted ureteral stones, with an average of 1.3 sessions. The success rate (rate free of calculi plus that of clinically insignificant residual fragments) was 98.3 %. No general or regional anesthesia was required but parental analgesics were required in 22.9% of the treatment sessions. There were no significant complications in any patient. Therefore, extracorporeal shock wave lithotripsy with Dornier MPL 9000 lithotriptor is considered to be a safe and efficient procedure for initial treatment of urinary stones.

Leiomyoma of the urethra is a rate entity. We experienced a case of leiomyoma in the female urethra recently. A 45 year old multiparous woman was admitted to the Department of Urology, National Police Hospital with the chief complaints of painless mass on the anterior lip of the external urethral meatus and contact bleeding. The mass was enucleated surgically and confirmed to be a leiomyoma pathologically.
