Evaluation of Tunica Vaginalis Free Graft as a Better Alternative to Tunica Vaginalis Pedicled Flap for Providing Waterproof Cover in Stage II Hypospadias Repair

BACKGROUND: Tunica vaginalis (TV) flap has been used by many surgeons as a waterproof layer to cover neourethra. We present our experience in using free TV graft as an alternative to TV flap for providing waterproof cover in second-stage hypospadias repair. MATERIALS AND METHODS: A retrospective rev...

description BACKGROUND: Tunica vaginalis (TV) flap has been used by many surgeons as a waterproof layer to cover neourethra. We present our experience in using free TV graft as an alternative to TV flap for providing waterproof cover in second-stage hypospadias repair. MATERIALS AND METHODS: A retrospective review of ten patients with severe hypospadias who underwent Stage II hypospadias repair over a period of 15 months was carried out. Free TV graft was used to cover neourethra in all the patients. RESULTS: The median age of patients was 3.5 years. Six patients had proximal hypospadias with severe chordee and four patients had peno-scrotal hypospadias. Eight patients had undergone Byars procedure and two patients had undergone Bracka's procedure during the first stage repair in the same institute. The mean operative time for Stage II repair using free TV graft was 150 min (standard deviation ± 15 min). All patients passed urine in good stream following stent/feeding tube removal. The average duration of hospital stay was 11 days. None of our patients developed urethrocutaneous fistula. Only one patient had superficial surgical site infection. All patients are well on follow-up after 6 months. CONCLUSION: Free TV graft could be used in place of TV flap as an intermediate waterproof cover to reduce the incidence of urethrocutaneous fistula in staged II hypospadias repair; however, studies involving a larger number of patients would be required to draw conclusions.
