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.
