Transurethral cystolitholapaxy in children.

Five boys, 5 to 9 (mean 6) years old, who had primary vesical stones underwent transurethral cystolitholapaxy. All stones were disintegrated by the 3F metal probe of the Swiss Lithoclast, which is perfectly adapted to the working channel of the 10F and 12F pediatric cystoscopes. A 13F sheath was then used to wash out the stone fragments. The mean stone diameter was 1.1 cm, and the mean operating time was 15 minutes. A 1-day hospital stay was recorded for all patients with no morbidity. During a follow-up period of 3 to 13 (mean 7) months, there were no micturition disturbances and no urinary tract infections, and uroflowmetry findings were normal. On the basis of this initial experience, we believe that transurethral cystolitholapaxy by Swiss Lithoclast is a potential alternative to cystolithotomy in selected pediatric cases.
