THE FREQUENCY of congenital malformations of the urinary tract is well appreciated. Patent urachus is one of several anomalies of the umbilical stump and its embryologic constituents. It occurs rarely enough in a female baby to warrant reporting, with a review of the embryology, diagnosis, and treatment of the lesion.

Report of a Case  This was a Negro female infant (Register No. 124033). the product of the spontaneous delivery of a full-term, uncomplicated pregnancy. The patient was brought to USAF Hospital Andrews at age 10 days because of passage of urine from the umbical stump since separation of the cord on the previous day. Questioning revealed that there was umbilical drainage only during micturition per urethra. On physical examination, a projection of the umbilical cord stump was covered with skin except for its distal extremity which was granulating cleanly. It appeared remarkably like a penis, as seen in Fig 1.
