Abstract
This is a report of two cases of congenital vesical diverticula in infants. Case 1 is a 2-month-old boy with acute urinary retention and consequent acute renal failure, and case 2 is a 5-month-old boy with urinary tract infection due to left vesicoureteral reflux. Thirtyeight other cases of infants and children in the Japanese literature are reviewed. Congenital vesical diverticula are more frequent in male (38 of 40 cases), and mainly located around the ureteral hiatus (32 of 40 cases). Acute urinary retention and urinary tract infection are the main presenting symptoms of vesical diverticula.
