The purpose of this study is to compare primary repair procedure with those that use bio-concordant materials in the treatment of urethrocutaneous fistula. Twenty-five New Zealand rabbits were randomly placed into five groups (primary repair, free graft, allograft fascia lata, alloderm and bovine pericardium repair groups). A single dose of 20 mg/kg of ceftriaxon was applied intramuscularly as a prophylactic dose. Urethrocutaneous fistula was formed on midpenile level. Later, while primary repair was applied in one group, repair with free grafts and with other bio-concordant materials were performed in other groups. Urinary diversion was not used in any of the rabbits. The macroscopic observation was evaluated with urethrography obtained 21 days after the operation and then the rabbits were sacrificed. A total point was obtained by awarding a point to each good parameter in the histopathological evaluation and all the groups were compared. The urethrographic findings and macroscopic examinations were normal in all groups. In histopathological examinations, ranging from the best to worst results, bovine pericardium group (8 points) had a better total score than primary repair group (7 points), allograft fascia lata group (7 points) and alloderm group (7 points). The free graft group had the worst total point (6 points). Bio-concordant materials can be used in urethrocutaneous fistula repair as an alternative to primary repair or to the grafts obtained from body tissues.
