Congenital anterior urethral diverticulum and recurrent urinary tract infection.

A patient with congenital anterior urethral diverticulum is described. He showed recurrent lower urinary tract infection, but he did not have severe upper urinary tract abnormalities. One-stage resection and urethroplasty were successfully performed before the upper urinary tract change developed. Anterior urethral diverticulum should be considered as a cause of recurrent lower urinary tract infection in young children.
