Tubularized Reconstructed Plate Urethroplasty: An Alternative Technique for Distal Hypospadias Repair.

To report current results of a new surgical technique, tubularized reconstructed plate urethroplasty (TRPU) in distal hypospadias repair which allows the tubularization of urethral plate without incision or grafting. This study is a prospective single surgeon series. Between January 2019 and March 2020, total of 158 patients underwent hypospadias repair, and 29 selected patients had TRPU procedure. Demographic data, duration of follow-up, complications were recorded. A vertical incision is made starting from halfway up the glans. This incision creates a diamond like defect which enables wedge removal of a segment of spongiosum tissue from the base of urethral plate extending to the hypospadiac meatus. Vertical incision is closed horizontally. The urethral plate is stretched and loosened from the base and re-secured into its bed using quilting stitches. Reconstructed urethral plate ensures the required width to allow the formation of neourethra of adequate circumference, followed by a formal glansplasty. Preoperative glans width was 13.4 ± 0.9 mm, urethral plate width was 6.1 ± 0.9 mm. Mean postoperative follow-up period was 13.6 months. All patients had successful functional outcome and cosmetically satisfying appearance. None of the patients required meatal calibration. The total complication rate was 3.4%. Native urethral plate itself is used as a natural flap to increase the surface area of the urethral plate in this new perspective of urethroplasty method. We believe that TRPU procedure provides an alternative approach for the formation of neourethra and it is a successful and relatively simple procedure with low complication rates, good cosmetic results and promising successful functional short-term outcome.
