Onlay free preputial graft for mid and distal penile hypospadias Onlay free preputial graft for mid and distal penile hypospadias Onlay free preputial graft for mid and distal penile hypospadias Onlay free preputial graft for mid and distal penile hypospadias Onlay free preputial graft for mid and distal penile hypospadias ABSTRACT ABSTRACT ABSTRACT ABSTRACT ABSTRACTTubularized free preputial graft for hypospadias repair had been tried in the past and discarded due to high incidence of graft shrinkage causing stricture formation. We have tried to revive the technique using onlay method thus avoiding stricture formation. The technique was used in 33 subjects (Group A) and compared with 33 subjects in control group (Group B) in whom other techniques of urethroplasty were used. The study was a randomized controlled trial. The mean length of the free preputial graft was 22.06 + 4.68 mm (16-35 mm) and breadth was 9.0 + 1.32 mm (7-11 mm). Fistulae developed in 3 patients in group A out of which one healed spontaneously. In group B, 6 patients had fistula formation. Complications developed in 18% cases in group A and 50% cases in group B. There was significant difference between the cosmetic results (p < 0.05) with 58% excellent results in group A and 27% in group B. Free preputial graft onlay urethroplasty has better functional and cosmetic results. KEY WORDS: Hypospadias, Free preputial graft, Onlay urethroplastyHypospadiology is an over expanding field as none of the current methods of urethroplasty have been proved su perior over the others in terms of achieving the goal of excellent functional and cosmetic results. We have de scribed our experience with free inner preputial full thick ness onlay graft urethroplasty in mid and distal penile hypospadias and compared our results with currently used technique.

BACKGROUND Aims and Objectives-To study and compare the outcome of Onlay Preputial Island Flap (OIF) and Tubularised preputial Island Flap (TIF) urethroplasty in children with hypospadias. MATERIALS AND METHODS Observational comparative study conducted between August 2004 and January 2007; 45 children with hypospadias underwent single stage urethroplasty, 27 children without chordee underwent OIF and 18 with chordee underwent TIF. The outcome and complications were noted and compared. RESULTS Complications were seen in 7 children of OIF group (25.9%) and 8 children of TIF group (44.4%). The overall commonest complication was Urethrocutaneous Fistula (UCF). Fistula rates were higher in the OIF group (22.2%), whereas strictures were only seen in the TIF group (22.2%). There was one flap necrosis in the TIF group (5.5%). CONCLUSION OIF and TIF are popular single stage procedures and are reliable techniques in hypospadias repair. In our prospective observational study, OIF had low complication rate when compared to TIF. UCFs were seen in the OIF group and stricture in the TIF group.

“…Since Duckett rst described the transverse preputial island ap urethroplasty (TPIF), the surgical procedure for repairing hypospadias has been widely used [10]. However, the disadvantage of the operation is that the learning curve required to grasp this technique is steep, as well as intractable complications [11][12][13][14].…”

Purpose: To evaluate the indications and postoperative complications of our new modified Duckett urethroplasty.Methods: A total of 133 patients with proximal hypospadias who underwent repair of the modified Duckett urethroplasty from February 2016 to February 2021 were reviewed. The median age of patients was 3 years (range 1-16). All patients had severe chordee. One senior experienced pediatric urologist performed all the surgeries. Catheter was removed 14 days after the surgery.Results: The location of the urethral meatus was proximal penile in 26 patients (19.5%), penoscrotal in 60 (45.1%), scrotal in 31 (23.3%), and perineal in 16 (12.0%). The mean length of the urethral defect was 4.5 cm (range 2.5-10). The median duration of follow-up was 46 months (range 8-67). Complications occurred in 31 patients (23.3%), including urethra-cutaneous fistula in 22 (16.5%), urethral stenosis in 7 (5.3%), and urethral diverticulum in 2 (1.5%). No recurrent chordee were found in all cases. All patients who developed complications were treated successfully at our hospital. Conclusion: Our modified Duckett urethroplasty showed functionally and cosmetically favorable outcomes, with a lower incidence of postoperative complications. To the best of our knowledge, the novel Duckett technique is a feasible and suitable option for patients who suffer from proximal hypospadias with severe chordee and dysplasia of the urethral plate.
