Abstract

Introduction: Hypospadias is a congenital anomaly, for which number of procedures had been described. We compared Mathieu’s flip flap, Onlay transverse preputial flap urethroplasties with Tubularized incised plate urethroplasty (TIP) as described by Snodgrass. This had been reported with the better results of meatal cosmesis and lesser complication rates.

Methods: These three procedures were done in patients, who had coronal, subcoronal, distal penile hypospadias, mid penile and proximal penile hypospadias in which urethral plate was not removed for the chordee correction. Following points were assessed. Meatal stenosis, Urethrocutaneous Fistula, Penile edema, Glanuar dehiscence ,Wound dehiscence

Results: Total 74 boys with mean age 6.22 years ± 4.26 were included in this study  Mathieu’s urethroplasty (n=14), Onlay (n= 23) and Snodgrass TIP urethroplasty (n=37) . Meatal stenosis occur in one patient each in Mathieu’s and Onlay procedure as compared to Snodgrass TIP (n= 7) out of which 6 patients improved later on, with meatal dilatation. 15 patients developed fistula in TIP repair as compare to total 12 patients in Mathieu’s and Onlay procedure. Five patients had dehiscence of glans in Mathieu, and Onlay procedure as compared to Snodgrass procedure in which none of the patients had glans dehiscence and it is statistically significant (P < 0.05).

Overall complication rate came out to be 24.3 % in TIP procedure as compare to 32.4% in Mathieu’s and Onlay procedure in combined. It was found that chances of improvement in TIP were higher by 48.33%.

Conclusion: It is concluded that TIP is as good as Mathieu’s and Onlay procedure with slight advantage of its use in reoperative surgery and cosmetic look and high chances of improvement in TIP.

Keywords: Mathieu’s flip flap; Onlay transverse preputial flap urethroplasty; Tubularized incised plate urethroplasty (TIP).
