Abstract

Background: Hypospadias is an abnormality of anterior urethral and penile development in which the

urethral opening is ectopically located on the ventral aspect of the penis proximal to the tip of the glans

penis, which, in this condition, is splayed open. [1] The urethral opening may be located as far down as in the

scrotum or perineum. The penis is more likely to have associated ventral shortening and curvature, called

chordee, with more proximal urethral defects.

Aim: To compare the outcome of using tunica vaginalis flap to dartos flap in proximal two stage hypospadias

repair in reducing post-operative complication (dehiscence and fistula).

Materials and Methods: In the defined period of January 2015 to June 2018, 47 male patients with clinical

diagnosis of penoscrotal hypospadias, The age of the patients range from 2 years to 10 years, All these

cases were managed in 2 stages repair with buccal mucosal graft, with either tunica vginalis flap (group A)

(25 cases) , or preputial dartos flap (group B)(22 cases) as a second cover over new tubularized urethra. We

compared between these two groups regarding complications rate.

Result: we observed that tunica vaginalis flap was better than dartos flap (although it was statistically non

significant p value 0.214 > 0.05) specifically in fistula formation.

Conclusion: we observed that tunica vaginalis flap had excellent outcome when used as a second layer over

the neourethral suture line in term of decrease the fistula rate and wound dehiscence because of its good

vascular features
