Is Dorsal Inlay Graft (DIG) With TIP Repair Superior to TIP Alone for Primary Hypospadias?
Sponsor: Mohammad Daboos
Summary
This prospective, randomized study included all patients who presented with primary hypospadias without chordee, Patients were randomized into two groups as group 1 or group 2,Group 1: Repaired with standard TIP repair as described by Snodgrass Group 2: Repaired with TIP with GIP using preputial graft. In both groups the functional outcomes were primarily compared regarding meatal position, shape, and the functional outcomes of the neourethra, in addition to other complications such as UCF, wound complications, cosmetic results and the need for a second surgery. the investigators aimed to investigate whether GIP with TIP repair is superior to TIP, as described by Snodgrass in different types of UP and to provide an overview of the technical aspects of current TIP repair practices.

Repaired with standard TIP repair as described by Snodgrass
Urethroplasty was performed over a 6-8 Fr Nelaton catheter (according to patient age and glans size) using 7/0 subcuticular continuous suture. Adequate meatus was left around the urethral catheter at the glans tip, followed by spongioplasty and a second-layer dartos fascia coverage. Mucosal collar approximation and skin closure Glanular closure was then initiated with deep but superficial stitches using 7/0 or 6/0 polyglactin suture, and mucosal suture closure. Skin closure was achieved by preparing viable skin while avoiding midline skin closure by preparing a vascularized preputial skin flap to avoid skin coverage complications with subsequent UCF
Repaired with TIP with GIP using preputial graft
The urethral plate was deeply incised from the glans tip, extending downwards beyond the junction between the plate and the hypospadiac meatus Graft fixation The graft was then spread to cover the raw area and fixed to the edges of the urethral plate.
