Abstract

Objective— To report a surgical technique for creation of a urethral conduit using a preputial indirect flap.

Study Design— Case report.

Animals— Male Doberman Pinscher (6 weeks old).

Methods— A urethral conduit was constructed using a multistage preputial indirect flap in a dog with severe perineal hypospadias.

Results— Successful transfer of a perineal located urethral meatus to a more anatomically normal inguinal location was achieved with a preputial flap. The procedure was performed to aid control of recurrent urinary tract infections after anal and urethral separation in a dog with imperforate anus, urethrorectal fistula, and proximal perineal hypospadias.

Conclusions— Creation of a urethral conduit from a tubed bipedicle flap using redundant preputial tissue eliminated fecal contamination of the urethral meatus, aiding control of urinary tract infection. A good functional and cosmetic outcome was achieved.

Clinical Relevance— This technique should be considered in aiding control and prevention of urinary tract infections in dogs with proximal perineal hypospadias where a preputial remnant exists.
