Case 1: A male infant underwent a sigmoid colostomy for supralevator imperforaie anus. A urological study revealed recto-vesical fistula and urethro-ejaculatory reflux. At 3 months of age the boy had painful swelling on the left scrotum. An acute epididymitis was diagnosed by surgical exploration. The symptoms subsided by oral antibiotics administraticn. Case 2: A newborn baby underwent a sigmoid colostomy for supralevator anorecral malformaion. At 6 months of age he suffered from left scrotal pain and swelling. From the experience of preveous case acute epidiymitis was diagnosed. The administration of oral antibiotics resulted in an improvement of the symptoms. At 11 months of age a urethro-ejaculatory reflux was proven by voiding cystourethrogram. Case 3 : A newborn baby complained of constipation and abdminal distension and a diagnosis of rectal stensis was made at 4 days after his birth. Dilatation of the rectum by bougie was repealed in another hospital. He visited to our Center at one month of age and a colostomy was performed for constipation and colitis. At 4 months of age swelling and redness were observed on his left scrotum. Exploratory operation was performed because there was a doubt of testicular torsion. Acute epididymitis was diagnosed again and he was treated by antibiotics, which resulted disappearence of the symptoms. Acute epididymitis is uncommon in children. The presented three cases of acute epididymitis were associated with anorectal malformation in all. This malformation may be pre-exsisting factors which may induce an acute epididymitis in the special case. Urological examination should be performed in the early course of treatment for anorectal anomalies. If urethroejaculatory reflux was diagnosed, care must be taken to prevent epididymitis and oral administration of antibiotcs should be given before the radical surgery is advisable.
