Diphallus is a rare anomaly and accompanying anomalies vary from bifid scrotum, bladder exstrophy, imperforate anus and colo-rectal anomaly such as duplication, and other associated anomalies.


A 2-day old infant is reported with imperforate anus and complete duplication of recto-sigmoid colon, rectal pouch, doubling of the genitalia with completely formed penis (diphallus), double bladder, urethra and hypospadias. No family history of abnormalities was noted. The patient underwent several operations: laparatory and colostomy at 3rd day of life, and after clinical and paraclinical investigations, cystoplasty, ureteral reimplantation and resection of left phallus were carried out when 4 months old. At the age of 1 year, after colostogram and total colon evaluation, laparatomy, resection of duplicated recto-sigmoid colon, and pull-through was carried out; 3 months later colostomy closure was performed and the patient discharged without complications.


The patients with diphallus have to be examined carefully because of the high incidence of other systemic anomalies. Treatment of diphallus usually includes excision of the duplicated penile structure, its urethra, and repair of associated anomalies.
