Introduction: Several techniques have been described for the repair of hypospadias but without any definitive privilege of one technique over the others. The choice of the repair remains largely dependent on the judgment and personal experience of the operating surgeon.
Aim of Study: The aim of this study was to identify the most commonly encountered complications following tubularized incised plate (TIP) urethroplasty and their rate of occurrence in relation to different forms of hypospadias.
Patients and Methods: This study was conducted on patients with different degrees of hypospadias (ranging from distal penile to scrotal hypospadias) who underwent primary TIP urethroplasty. All included cases were operated by the same surgeon (the author) at two tertiary centers for pediatric surgery during the period 2007 through 2016. Data analysis was performed in a retrospective manner based on retrieved medical records, in addition to saved digital photography documenting the preoperative phenotypic severity of the hypospadiac phallus, operative steps, appearance at follow-up visits, postoperative investigations, and reoperations.
Results: We retrieved data of 193 patients with different degrees of hypospadias who underwent a primary TIP urethroplasty during the 10-year period of the study. All cases in the study completed their early postoperative follow-up (at 1 and 4 weeks). Approximately 40% of cases completed more than 1-year follow-up (mean: 2.3 years, median: 2 years). Rate of reoperation was 21.7% (20 cases for fistula, five recurrences of chordee, one meatal stenosis, and 16 skin refashioning and correction of penoscrotal interposition). All cases who returned for reoperation underwent urethral calibration under anesthesia±cystoscopy.
Conclusion: TIP urethroplasty is a versatile technique that can be used for the repair of different degrees of hypospadias with low rate of complications. The main limitation is the presence of considerable chordee (moderate or severe) when urethral plate preservation and dorsal penile plication might be a suboptimal way of management that is liable for recurrence of the ventral curvature
