An eight-week-old male Boston terrier presented for penile desiccation and urine pooling in the prepuce due to congenital hypospadias. An advancement flap was created from the dorsal mucosa of the incompletely formed prepuce and sutured circumferentially to construct a longer distal preputial mucosa. V- to Y-plasty of the ventral abdominal skin was utilised to create the preputial skin overlying the mucosal flap. Urethrostomy and partial penile amputation were also performed. Following surgery, the clinical signs of penile desiccation and preputial urine pooling resolved and acceptable cosmetic appearance was achieved. This technique may be considered for glandular or penile hypospadias or following resection of the ventral aspect of the distal prepuce when inadequate tissue is present for a simple two-layer closure of the preputial mucosa and skin.
