A rare case of adult diphallus with anorectal malformation

We present the case of a 24 year old man who presented with acute urinary retention and found to have diphallus with vertical duplication of penis. Superior phallus was well developed without any urethral meatus whereas inferior phallus was rudimentary but with patent urethra. History of erection was present in superior phallus only whereas patient was voiding urine from inferior phallus. It was associated with anorectal malformation and bilateral pelvic ectopic kidneys. Patient was managed by suprapubic catheter placement and planned for penile and urethral reconstructive surgery. Diphallus very rarely present in adulthood and vertical duplication is very unusual.
