TUBULARIZED INCISED PLATE URETHROPLASTY FOR ONE-STAGE HYPOSPADIA REPAIR IN CHILDREN AT HASAN SADIKIN HOSPITAL BANDUNG

Objective: To determine the outcome of tubularized incised-plate (TIP) urethroplasty for one stage hypospadia repair in children. Material & methods: A 7-year retrospective experience at Hasan General Sadikin Hospital Bandung on the outcome of tubularized incised plate for one-stage hypospadias repair in children during 2009-2015. Results: A total of 102 children was undergone one stage hypospadias repair with TIP urethroplasty. The mean age was 6.97 years old. As much as 65 (63.72%) children had distal, and 37 (36.28%) children had proximal hypospadia. The mean length of surgery was 112.56 minutes. Post operative complications was rarely found, consisting of 5 (6.32%) children had urethrocutaneus fistula formation and 11 (13.9%) children had haematoma. 4 (10.81%) children with proximal hypospdia and 1 (1.53%) children with distal hypospadia had urethrocutaneus fistula formation. 4 (6.15%) children with distal hypospadia and 7 (18.91%) children with proximal hypospadia had haematoma. Conclusion: Tubularized incised-plate (TIP) urethroplasty for one stage hypospadia repair in children was highly effective with rare complications comparable with recently published study.

Hypospadias Surgery

BackgroundTubularized incised plate urethroplasty is the most common hypospadias repair technique. However, there are unanswered questions and debates about the anatomical prognostic factors affecting the repair outcomes. This study tried to address some of the problems in the studies compromising the results of the current body of literature.MethodsA prospective cohort of 101 males aged 1–3 years undergoing primary distal to mid-shaft hypospadias repair were enrolled in the study. Complications including edema, erection, inadvertent removal of the urethral stent, surgical wound infection, bladder spasm, hematoma, and hemorrhage were evaluated. Studies in the current literature were reviewed to achieve a better perspective for future investigations.ResultsPersistent complications were found in 16 cases (15.8%) including fistula formation, the persistence of chordee, meatal stenosis, glans, and urethral dehiscence. The mean follow-up time was 6.6±3.4 months. In the single-variable analysis, the meatal location, the length and width of the urethral plate, and the reversible acute postoperative events were significantly associated with the complications. Furthermore, fistula formation was associated with acute surgical site infection (p<0.001). However, the multivariable regression study revealed the presurgical meatal location to be the only statistically significant factor (p=0.03). Notably, the glans diameter or glanular groove shape, urethral plate dimensions, or presence of mild chordee were not independently associated with the outcomes (p>0.05).ConclusionsOur study on the toddlers with hypospadias surgery revealed that the location of urethral meatal was the main predicting factor in the development of major complications. Furthermore, the fistula formation at the infected surgical site emphasizes the importance of postsurgical care.

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.

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
