A 8-year-old male child with complaint of hematuria was reported. Cystoscopy demonstrated a periodically dilating right ureteral orifice. Excretory urography associated with pneumoretroperitoneum revealed a so called “snake cap” at the terminal portion of right ureter. Ureterocelectomy was done and the postoperative course of the patient was uneventful.
Only 11 cases of ureterocele in infants and children have been reported in Japan. The reason why much more cases have not been reported is attributed to the fact that the pediatric urology has not yet well developed in Japan.
It was emphasized that cystoscopic examination should be conducted in any child with persistent pyuria.
