Purpose: To compare the success rate of the simple two-layered “Goldstein and Hensle techniques” and the triple-layered ‘pants-over-vest’ repair for denovo fistula post hypospadias repair. Patients and Methods: A randomized controlled trial was carried out for denovo post hypospadias fistula. Inclusion criteria were patients with age ≥ 6 months and all repairs were done at least after 6 months from the primary repair. Patients will be allocated into 2 groups, patients will undergo simple two-layered closure (Group 1), while in Group II; patients will undergo triple-layered double flap closure, the pants-over-vest repair. The primary outcome is success which defined as no fistula recurrence within 6 months post the repair. All patients were followed up at 1,3, and 6 months. The function assessment was done for successful cases in both groups either voiding or cosmetic outcomes. Results; A total 91 patients met the inclusion criteria between November 2021 to December 2023. Patients were grouped according to fistula site to distal (85%) and proximal (15%). Fistula was characterized according to size (>2mm and <2mm) and number (single and more than one). The overall success rate was 62.5% in simple two layered repair versus 82.5% in triple-layered with significant difference (p>0.039) during follow up. No patients had any major complications during the early or delayed postoperative periods. There was no impaction on success rate regarding the age of patients, fistula characters, and duration to fistula repair. The majority of patients in both groups were satisfied with micturition in more than 90%. PVR in all cases is insignificant. The PPPS showed no significant difference between the two groups in terms of total score (p>0.95). Conclusions: The triple-layered repair technique was better than the simple repair technique regarding recurrent fistula formation with comparable high satisfaction in functional and cosmetic outcomes. The significant success rate in the repair with the addition of a waterproofing layer recommended that rather than being saved for later use, this interposition layer should be used as soon as possible to reduce a recurrence.
