Abstract
Objective: To describe the ‘Bird-Winged Coronal-Collar Skin re-arrangement modification’ of the Tubularized Incised Plate (TIP) urethroplasty to preserve the inner preputial skin on the ventral surface of the penile shaft. Material and Method: Study Group: Prospective review of the results of a single surgeon with Bird-Winged Coronal-Collar skin re-arrangement modification of TIP urethroplasty (n=111; mean age 4.9 years) of distal (n=76) and mid-penile (n-35) hypospadias (mean follow-up 37 months). Control Group: Retrospective review of a single surgeon’s results of distal and mid-penile hypospadias repair with standard TIP urethroplasty (2007-11). Outcome parameters (to compare non-inferiority of the modified technique): Urethro-cutaneous fistula (UCF) at voiding trial and follow-up at 3 months, wound infection, complete dehiscence, local edema, meatal stenosis and quality of urinary stream. Statistical analysis was done with the Fischer Exact Test. Results: With this technique, the authors could provide an inner preputial cover on the ventral/ ventro-lateral aspects of distal penile shaft in all but one patient (complete dehiscence). The results of ‘bird-winged coronal-collar skin re-arrangement’ modification were not-inferior/ comparable to those of standard TIP urethroplasty. Conclusions: The modification is technically feasible and reproducible and the overall results of urethroplasty were not inferior to the standard TIPS procedure.
