Conditions

Urinary stone treatment with shock wave lithotripsy Urological and Genital Diseases Calculus of lower urinary tract

Interventions

Shock wave lithotripsy of ureteral and renal calculi. Duration of treatment is about 1h and there is only one single treatment per patient. The follow up is done by ultrasound, blood samples, x-rays
