Background: Reoperation for failed hypospadias has been considered to be seriously problematic. The dense fibrotic tissue causes difficulties in wound healing and increases the rate of complications. The tubularised incised-plate urethroplasty (TIPU) method has become a preferred method for all varieties of hypospadias in the past decade. However, fistulas are still one of the most common complications of this technique. The aim of this paper was to present the preliminary results of TIPU procedure with double de-epithelised dartos flaps in failed hypospadias repair., Materials and Methods: All patients were treated between January 2009 and August 2010 by the same procedure, utilising TIPU with double de-epithelised dartos flaps. Vascularised ventral dartos flaps harvested from each side of the penis with their vascular supply were transposed to cover the suture line by wrapping them from either side of the penis., Results: There were 21 boys with failed hypospadias: 20 had previously undergone TIPU, and one Koyanagi repair. Patients presented with very large fistulas in four and dehiscence in 17. Repair of the failed hypospadias using TIPU with double de-epithelised dartos flaps was quite successful, with no fistula recurrence or dehiscence observed., Conclusion: The preliminary results showed that TIPU with double de-epithelised dartos flaps is a useful method of successfully repairing failed hypospadias.

Purpose: We analyzed a new urethra preserving approach, double-cross flap protection, during tubularized incised plate urethroplasty. We compared the results of 57 patients treated with this new procedure and 80 patients treated with 2 different techniques., Materials and Methods: We studied 137 patients with hypospadias between October 2002 and March 2008. Patients were divided into 3 groups. Group 1 consisted of 40 patients (mean age 50 months) undergoing tubularized incised plate urethroplasty. Group 2 included 40 patients (mean age 48 months) undergoing tubularized incised plate urethroplasty with dorsal subcutaneous flap. Group 3 consisted of 57 patients (mean age 39 months) undergoing tubularized incised plate urethroplasty with 2 de-epithelialized preputial flaps twisted ventrally and sutured individually over the neourethra. All patients were operated on by the same surgeons. Statistical analysis of postoperative complications was performed by ANOVA and chi-square test., Results: In Group 1 fistula developed in 6 patients (15%) and was associated with stenosis of the neourethra in 4 (10%). In Group 2 fistula developed in 4 patients (10%). In Group 3 no fistula was observed, but mild stenosis of the neomeatus developed in 3 patients (5.3%), which was treated with dilation. Thus, the incidence of fistula in group 3 was significantly less (p = 0.015)., Conclusions: Double-cross flap protection is safe and significantly reduces the incidence of postoperative fistula.

Objective The aim of this study was to analyze retrospectively the 9-year experience of a single institution in the use of the double cross flap technique to interpose a double dartos flap to protect the neourethra with the aim of preventing fistula formation. Patients and methods Between October 2005 and September 2014 a total of 127 children with distal and midshaft primary hypospadias underwent tubularized incised plate urethroplasty by means of a double dartos flap obtained with a double cross flap to protect the neourethra. A Foley catheter was left in situ for 7 days. Success was defined as no incidence of complications requiring reintervention, along with good cosmetic result. A questionnaire was administered to estimate parental satisfaction. Parents were asked to evaluate the cosmetic appearance of the penis as good, acceptable, bad, or indifferent. Results The patient age at the time of surgery ranged from 12 months to 10 years (median 39 months). Three patients exhibited fistula at follow-up (2.3%). In two patients a glandular dehiscence of the urethroplasty occurred (1.5%). Mild stenosis of the neomeatus occurred in three patients (2.3%). No penile iatrogenic rotation occurred. A 'good' cosmetic result was reported by 68.5% of parents, acceptable by 22.8%, bad by 3.9% and indifferent by 4.7% of parents as per the parental questionnaire. Conclusion The double cross flap technique is not the panacea to prevent fistula formation in hypospadias surgery. Nevertheless, it offers an unquestionable advantage in terms of avoidance of fistula formation. The experience and skills of the surgeon performing urethroplasty remain the mainstay for best results.

Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Cyanoacrylates are tissue glues which polymerize when getting in contact with blood or water, creating a tight closure. It is usually used as octyl or butyl-cyanoacrylate, and in pediatric age it is applied to close tension free wounds, and it is as an alternative to conventional sutures. Its applications are in the management of low fistula-in-ano, or in the treatment of ano-rectal fistula; other uses include endoscopic treatment in the first episode of variceal bleeding, sutureless circumcision, and the closure of laparoscopic trocar site wounds. Lapointe SP et al. had applied n-butyl-cyanoacrylate glue to repair 'early fistulae' which occurred after urethroplasty with a good result. Our experience emphasizes that n-butyl cyanoacrylate may be applied to repair, not only 'early fistulae', but also the long standing ones with good results. OBJECTIVES • To evaluate urethrocutaneous fistula repair after urethroplasty using n-butyl cyanoacrylate (NBCA) in an outpatient setting. • To compare results of application of NBCA in 'early' and long-standing fistulae. PATIENTS AND METHODS • From January 2003 to December 2006, 13 children (mean age 36 months) were treated in our Outpatient Department for urethrocutaneous fistula, which occurred after hypospadias repair. • We analysed the data dividing the patients in two groups: group A comprised six children (mean age 22.6 months) that developed a fistula within 2-3 days of catheter removal after urethroplasty ('early' fistula) and group B comprised seven children (mean age 42.6 months) with long-standing fistulae. • In all patients, a multilayer of NBCA was applied, attaching the edges of the fistula taking care to perform a scarification of the edges of the fistula in patients in group B before the application of the glue. RESULTS • Four patients in group A and three patients in group B had definitive fistula repair (seven of 13), and six of the 13 had fistula recurrence. • Fistulae of ≤2 mm were more easily repaired than fistulae of >2 mm (five of seven vs two of six). • Fistulae that tended to recover were those that responded to the first applications. CONCLUSIONS • In this experience the use of NBCA as a minimally invasive treatment for fistula repair gave good results for repairing fistulae. • These preliminary results encourage the use of NBCA as a first non-surgical attempt to repair urethrocutaneous fistulae especially if the fistula is ≤2 mm. • The failure of this procedure does not compromise a possible subsequent surgical repair.
