Summary:
Objective: The aim of the study is to evaluate the role of
spongiosal tissue with dartos flap coverage for preventing
Urethrocutaneous Fistula (UCF) formation in the Snodgrass
technique.
Materials and Methods: It is a prospective study, performed
on 35 patients of mid penile and distal hypospadias aged 15
months to 144 months who underwent urethroplasty in the
Snodgrass technique using spongiosal tissue and dartos flap
for neourethral coverage.
Results: Among 35 patients, Age ranged from 15 months to
144 months (mean 85.94 months). Chordee was corrected by
penile degloving alone in 11 patients, partial mobilization
of urethral plate with spongiosum in 20 patients and 4
patients required dorsal plication. Glans groove was deep in
19 patients, shallow in 13 patients and no groove noticed in
3 patients. Sixteen patients had narrow urethral plate (<8mm)
and 19 patients had adequate urethral plate (>8mm).
Urethrocutaneous Fistula (UCF) was encountered in five
patients (14.28%), meatal stenosis in two patients (5.71%),
and partial glanular dehiscence in one patient.
Conclusions: Approximation of spongiosal tissue along with
dartos flap as the intermediate layer for neourethral coverage
reduces fistula formation.
Key words: Hypospadias, UC fistula, Meatal Stenosis,
Spongioplasty, Dartos Flap.
