Surgical Management of Perineal Hypospadia in a Dog

A three year old, crossbred intact dog was presented with history of urinary incontinence for past 3 days. On physical examination, external urethral orifice was opening at the ventral surface of the penis rather than the tip of glans with bifid scrotum, hence the case was diagnosed as hypospadias. The cause of the hypospadias is not known, it is presumed that the affected foetus may secret inadequate quantities of testosterone or that there may be inadequate conversion of testosterone to dihydrotestosterone in the target tissues of the urogenital sinus and external genitalia. In the present case, prepupial sheath was incomplete hence reconstructive surgery of the penile prepupial sheath was performed to cover the exposed dry penis and animal recovered uneventfully.
