Topography Guided Repair Versus TIP for Distal Hypospadias
Sponsor: Alexandria University
Summary
This study compares two surgical techniques used to repair distal hypospadias in children: topography-guided repair (TGR), a newer approach, and tubularized incised plate (TIP) repair, a commonly used standard technique. Children with distal hypospadias were randomly assigned to receive one of the two procedures. Researchers assessed early surgical complications, need for additional surgery, and postoperative appearance and function during follow-up visits over 12 months. The study aims to determine whether TGR can be safely adopted by surgical teams other than its developer and to guide larger future studies.

Topography Guided Repair
Topography-guided repair is a surgical procedure for primary distal penile hypospadias. The repair involves identification and mobilization of the spongiosal pillars, excision of the ventral hypoplastic urothelial sheet, approximation of the spongiosal tissue over a silicone catheter, and subcuticular closure of the glanular wings. An 8-Fr silicone catheter is maintained for 7 days after surgery.
Tubularized Incised Plate Repair
Tubularized incised plate repair is a surgical procedure for primary distal penile hypospadias. The urethral plate is incised in the midline and tubularized to create a neourethra, followed by glans closure using 6-0 polyglactin sutures. An 8-Fr silicone catheter is maintained for 7 days after surgery. Postoperative dressing and wound-care protocols are the same as in the topography-guided repair group.
