2004 Nov;94(8):1188-95. Review.
Hypospadias
is repaired by paediatric surgeons, paediatric urologists, adult reconstructive
urologists and plastic surgeons. This review is unique in representing all four
specialities, to provide a unified policy on the management of hypospadias. The
surgeon of whichever speciality should have a dedicated interest in this
challenging work, ideally having an annual volume of at least 40-50 cases. The
ideal time for primary repair is at 6-12 months old, although when this is not
practicable there is another opportunity at 3-4 years old. A surgical protocol
is presented which emphasises both functional and cosmetic refinement. Using a
logical progression of a very few related procedures allows the reliable
correction of almost any hypospadias deformity. A one-stage repair is used when
the urethral plate does not require transection and its axial integrity can be
maintained. Occasionally, when the plate is of adequate width and depth, it can
be tubularized directly using the second stage of the two-stage repair. When
(usually) the urethral plate is not adequately developed and requires
augmentation before it can be tubularized, then that second-stage procedure is
modified by adding a dorsal releasing incision +/- a graft (alias Snodgrass and
'Snodgraft' procedures). The two-stage repair offers the most reliable and
refined solution for those patients who require transection of the urethral
plate and a full circumferential substitution urethroplasty. From available
evidence this protocol combines excellent function and cosmesis with optimum
reliability. Nevertheless, it would be complacent to assume that these gratifying
results will be maintained into adult life. We therefore recommend that there
is still a need for active follow-up through to genital maturity.
