An “Institute Ethical Committee” approval was obtained. All children presented to the Department of Paediatric Surgery and Paediatric Urology with hypospadias were considered for the study. The children with only severe hypospadias (Proximal penile, Penoscrotal, Scrotal, and Perineal) were recruited for the study. All the children were operated by a single surgeon. The children with proximal penile hypospadias underwent Snodgrass repair. The children with Penoscrotal, Scrotal, and Perineal hypospadias underwent two-stage Bracka’s repair. Before the first stage, children with a small penis and/or glans received 100 IU/kg human Chorionic Gonadotropin twice weekly for three weeks and subsequently underwent chordee repair. Preoperative human Chorionic Gonadotropin was given in those patients where the penis was small and it was felt that an increased the size would make the surgery easier and therefore improve the outcome both in terms of function and cosmesis. The second stage repair was performed after six months.</p><p id="par0015" class="elsevierStylePara elsevierViewall">In all the patients, TVF was used to buttress the urethroplasty. On completion of the urethroplasty, the testis was delivered into the wound (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>A). A flap of the parietal layer of Tunica-Vaginalis was harvested taking care not to damage the vas and vessels. It was ensured that the length of the flap was long enough to prevent any torsion or chordee from the flap itself (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>B). The tip of the flap was tucked between the layers of glanuloplasty using 6−0 polydioxanone suture (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>C, D). A few tucking sutures were placed to fix the rest of the TVF (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>E). The TVF was covered by skin (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>F). The children were discharged home after three days. The urethral catheter was removed after eight days.

One hundred and forty-five (47%) had Penoscrotal hypospadias and 35 (11%) had Scrotal hypospadias with significant chordee requiring excision of urethral plate.
