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.

To assess the consequence of tubularized incised plate urethroplasty on primary hypospadias repair. Total of 42 male patients underwent hypospadias repair in AL-Diwaniyah Teaching Hospital/Iraq. from April 2016 to April 2018. The levels of the hypospadias defect, age at operation, type of sutures and dressing, type of catheter and time of removal and complications were verified. Tubularized incised plate urethroplasty done for all patients and mean patients age at operation was 4.4 years (range 1 year to 8year). Postoperative follow up was 1 to 3 months. Generally, meatal stenosis, dehiscence due to infection and an urethrocutaneous fistula occurred in 3,2and 6 patients, respectively. T.I.P. urethroplasty has come to be the favourite surgical procedure of distal hypospadias cases at our hospital. The technique has a small number of complications in addition to prove success and adaptability that continue to increase its application.

Background/purpose: The tubularized incised plate urethroplasty (Snodgrass technique) presents the procedure of choice for distal hypospadias repair. Fistula formation is the most common complication with various rates. Avoiding overlap of suture lines in the Snodgrass repair is critical to minimize fistula formation through second-layer coverage of the neourethra. We compared the outcome of double- layer dartos flaps to flapless procedure in the tubularized incised plate urethroplasty for distal hypospadias repair to assess the effectiveness of dartos flap in this method.Methods: Our study included 28 patients aged upto 12 years who were treated with tubularized incised plate urethroplasty for distal hypospadias in Shaheed Suhrawardy Medical College Hospital from April 2010 to December 2011. They were divided into two groups. Group A (14 patients) had double dartos flap coverings. Group B (14 patients) had no dartos flap covering. The dissected dorsal dartos flap was bisected vertically to form two pedicle wings. Each wing was rotated laterally from either side of the glans to cover the neourethra ventrally in a double-layer fashion.Result: Mean follow up period was 9 months. In Group A, one patient (7%) developed fistula and one (7%) superficial skin necrosis. On the other hand three (21%) patients developed fistula and one patient (7%) meatal stenosis in group B, who were treated with Snodgrass procedure without using dartos flap. All successful repaired hypospadias patients of both groups had a cosmetically normal looking circumcised penis with ventrally slit meatus.Conclusions : Double dartos flaps covering of the neourethra is a simple procedure and could be effective for the prevention of urethrocutaneous fistula after tubularized incised plate urethroplasty.J.

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

Background. Hypospadias has a wide spectrum of penile abnormality requiring surgical correction. Most of the cases are of anterior variety and the surgical technique depends on constructing a neo urethra. Snodgrass or Tubularized Incised Plate (TIP) urethroplasty is one of the most popular techniques of urethroplasty which depends on the existing healthy, adequate and intact urethral plate. Different tissues have been described to cover the neourethra as second layer in literature. In this study we modified the TIP urethroplasty by covering the neourethra with 2 layers of pedicled prepucial mucosa or Dartos flap. Objective. To see the outcome of modified Snodgrass or TIP urethroplasty in anterior mid and proximal penile hypospadias. Materials and method. Total 88 patients were operated by modified Snodgrass technique or modified TIP urethroplasty from January 2012 to July 2016. Coronal, subcoronal, distal penile, mid penile and proximal penile hypospadias were included in the study. Every patient underwent modified TIP urethroplasty and outcomes were assessed. Results. The mean age of the patients were 28.34±14.98 months, ranges from 6.5 to 65 months. 9 (10.2%) patients of our series develop urethrocutaneous fistula, 5 (5.68%) patients develop meatal stenosis and 1 (1.1%) patient developed neourethral stricture. Conclusion. TIP urethroplasty is a versatile method to correct penile hypospadias. Covering of the neourethra with prepucial mucosa secure the neourethral anastomosis. The author declares that there is no conflict of interest. Key words: Hypospadias, TIP urethroplasty, Prepucial mucosa.
