Surgical technique for midshaft hypospadias has evolved since the time of Horton and Devine. The most common type of repair that is currently used is the tubularized incised plate urethroplasty, which is a modification of the Thiersch-Duplay hypospadias repair. The authors review the steps of this procedure in detail and discuss troubleshooting for issues that may arise during the repair. Alternatives for chordee correction and skin coverage are reviewed. The authors briefly discuss outcomes and possible complications. In addition, there is a step-by-step video of a midshaft hypospadias repair that highlights the surgical technique. This review contains 9 figures, and 23 references.

Introduction Several urethroplasties have been employed in the surgical treatment of hypospadias. Neourethral strictures are among the most common postoperative complications that often require reoperation. Materials and Methods We created a hypospadias model in New Zealand white male rabbits through a hypospadias-like defect and acute repair. A total of 24 animals were randomly allocated into three groups: tubularized incised-plate urethroplasty (TIPU) group (8), perimeatal-based flap urethroplasty (Mathieu) group (8), onlay island flap urethroplasty (onlay) group (8), and corresponding surgical procedures were immediately performed to reconstruct neourethra. The rabbits were killed postoperatively at 5 days, 2 weeks, 6 weeks, and 3 months, respectively. The penile tissue was harvested for histological and biochemical investigations to evaluate the expressions of transforming growth factor β1 (TGF-β1) and α-smooth muscle actin (α-SMactin) in all groups. Results All rabbits were operated on uneventfully. The amount of collagen content was increased in the Mathieu and onlay groups than in the TIPU group (p < 0.05). Biochemical analysis showed that the expression of TGF-β1 in the TIPU group was decreased compared with the two other groups at 2 or 6 weeks postoperatively (p < 0.01). The expression pattern regarding α-SMactin was similar at 6 weeks or 3 months postoperatively (p < 0.01). Conclusion The neourethra repaired by TIPU was practically resumed to normal anatomy and scarring was less apparent than the two other groups. Therefore, TIPU is considered as a relatively rational approach for hypospadias repair. The activity of fibroblasts has been increased in the long term, which may be the pathogenesis of neourethral stricture following hypospadias repair.

Background: Hypospadias surgeries are often complicated with fistulas, meatal stenosis and disruptions. We report our series of redo surgeries for failed primary repairs. Methods: We prospectively observed all the redo hypospadias repairs done by the principal author between 2013 and 2017. Thiersch-Duplayurethroplasty was done if the urethral plate was adequately wide and intact; tubularized incised plate (TIP) urethroplasty was performed if the urethral plate was intact but, narrower than 8 mm; 2 stage procedures were done with oral mucosal graft (OMG) if the urethral plate was deficient or scarred with significant chordee. Result: There was a total of 31 patients. Age ranged from 18 months to 15 years (mean 8.05 ±4.27 years). Sixteen (51.61%) patients underwent only one surgery, 10 (32.26%) patients underwent 2 surgeries, 2 patients (6.45%) underwent 3 surgeries, and 3 patients (9.68%) underwent 4 surgeries prior to presenting to us before our redo surgeries.We had performed TIP urethroplasty in 16 (51.61%) patients, meatal based flap urethroplasty in 12 (38.71%), OMG followed by urethroplasty in 2 (6.45%), and repair of urethra-cutaneous (UC) fistula in 1 (3.23%) patient. Ten (32.26%) Complications occurred in 8 (25.80%) patients. Unsuccessful repair was noted in 03 (9.67%) patients (UC fistula 1, glans dehiscence with UC fistula 1, and glans dehiscence 1). Conclusion: Thiersch-Duplay and TIP repair can be successfully performed in redo hypospadiassurgeries with acceptable complication rate. OMG graft can be reserved for cases with gross scarring of the urethral plate. Keywords: Failed hypospadias repair; Tubularized incised plate urethroplasty; Thiersch-Duplay; Outcome
