The mean time interval Background before presentation was 22 hours. All patients Penile fracture is a relatively rare acquired urologic presented with the classical symptoms of penile pain, condition which may occur following blunt trauma to swelling and detumescence. All patients had immediate an erect penis. The aim of the study is to review the penile exploration and repair of tunica albuginea via a presentation, management and outcome of penile circumferential sub- coronal incision. The mean period fractures in a tertiary hospital in Nigeria over a 7 year of follow up after repair was 9.3 weeks.

The mean age of the patients was 32.3 years. Blunt trauma during sexual intercourse was the mechanism Key words of trauma in 5 patients. In one patient it was due Penile fracture, Tunica Albuginea, Repair, Outcome Introduction The penis consists of two corpora cavenosa and a Penile fracture is a rare urologic condition which corpus spongiosum, which contains the urethra. occurs when there is a tear in the tunica albuginea The corpora are capped distally by the glans. A covering the corpora cavernosa as a result of blunt fascial sheath, the tunica albuginea encloses each trauma to an erect penis (1,2). It occurs usually corpus while a thick envelope, the Buck’s fascia during vigorous sexual intercourse when the erect surrounds the corporeal bodies.

Beneath the skin of the penis, the Colle’s injury include falling on an erect penis, rolling over fascia extends from the base of the glans to the on an erect penis during sleep, masturbation and urogenital diaphragm and continues as the Scarpa’s other forms of penile manipulation (2,3,4).

Five out of the 6 patients sustained penile hematoma is limited to the penile shaft if the Buck’s fracture during sexual intercourse, while in one fascia over the tunica albuginea is intact.
