[Extracorporeal shock wave lithotripsy monotherapy for a renal stone in a 15-month-old child].

A 15-month old child visited our hospital with the chief complaint of macroscopic hematuria. Intravenous pyelography (i.v.p.) revealed a right renal stone (20 x 18 mm) with hydronephrosis and hydroureter. Extracorporeal shock wave lithotripsy (ESWL) was performed twice using a SEMENSE LITHOSTER for the stone. A cardboard and a towel were used to protect the lung and for focusing the shock waves. We achieved complete stone clearance with the ESWL monotherapy. I.v.p. and voiding cystography (VCG) after ESWL revealed disappearance of right hydronephrosis and hydroureter and no reflux. As of June 1995, his general condition is good and there are no recurrent stones.
