Outcomes of preputioplasty in patients undergoing TIP urethroplasty (tubularization of incised urethral plate) for distal and mid penile hypospadias.

Abstract：

BACKGROUND:Preputioplasty as a part of hypospadias repair restores the normal appearance of phallus, which is especially important in distal and mid penile hypospadias. However possibility of its inherent complications such as iatrogenic phimosis or preputial breakdown are the cause of controversy and reluctance regarding this procedure.This study evaluates the results of preputial reconstruction with TIP urethroplasty in distal and mid penile hypospadias repair and analyses if preputioplasty may be offered to these patients. MATERIALS & METHODS:In this prospective observational study, 48 cases of distal and mid penile hypospadias underwent TIP urethroplasty and preputioplasty and results were assessed at 2 weeks, 3 months and 6 months. Major complications included preputial dehiscence, tight prepuce (iatrogenic phimosis) and minor complications included ventral tethering, persistent dorsal whorls and redundant prepuce. Data was analysed with Microsoft Excel spreadsheet where descriptive statistics were obtained. RESULTS:Preputioplasty was performed in 48 children with a mean age of 5.1 years. Preputioplasty dehiscence was seen in three (6%) patients, which gave an appearance of irregular prepuce on 6 m follow up. Two patients (4%) were confirmed to have preputial tightness at 3 months but this resolved conservatively in one patient and only one patient (2%) required circumcision for a tight prepuce. Minor complications included ventral tethering, persistence of dorsal whorls and redundant prepuce. Ventral tethering was present in 3 patients (6.25%). Redundant prepuce was observed in 2 patients (4.16%). Additionally, unsightly dorsal whorls were found to be persistent in 2 children (4.16%). None of these patients opted for circumcision. The rest of the children had a cosmetically and functionally normal prepuce. Two patients (4%) developed urethrocutaneous fistula at 3 months' follow-up. CONCLUSION:Preputial reconstruction is feasible with a good cosmetic outcome and minimal complications in patients of distal and mid penile hypospadias undergoing TIP urethroplasty. Mild preputial tightness evolves over time and resolves with conservative measures. In patients with very prominent dorsal whorls and underlying bulky tissues the preputioplasty does not appear to be of satisfactory cosmesis. To help the patient and parents take a well informed decision, it would be useful to explain all possible major and minor foreskin complications, and their rectification.
