Introduction:
We present an alternative procedure for distal hypospadias consisting of urethral mobilization and glandular disassembly, named GUD-technique.
Material And Methods:
After circumcision and exposure of distal dysplastic urethra, it is entirely mobilized from corpora and glans. Glans is deconstructed and incised in midline producing two wings almost not connected to glandular urethra at all. The urethra is then mobilized cranially and sutured to the tip of glans. Glans wings embrace the distal urethra producing a refurbished conical glans.
Discussion:
Koff et al. published a technique consisting of extensive urethral mobilization for hypospadias repair. Mitchell & Blagi and Perovic et al. reported on complete penile disassembly for epispadia repair as a way to complete release of the rotation of the penis and treat chordee bringing the urethra to a more functional location. We incorporated these two principles in GUD. The rationale is to avoid suture urethroplasty, simply repositioning the mobilized urethra distally and working aggressively on glans disassembly creating a more conical and cosmetic glans. The aggressive deconstruction of glans makes this technique unique.
Conclusion:
We are convinced that this operation can be regarded as a genuine alternative to distal hypospadias after performing 100 cases in 3 years of experience.

Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...
