Partially de-epithelialized preputial flap (triangular soft tissue flap): an aid to prevent coronal urethrocutaneous fistulae.

A technique is described to fashion a partially de-epithelialized preputial flap, also called triangular soft tissue flap (TSTF), to cover the neourethra in the region of glans, corona and subcorona. This highly vascular TSTF acted as a mechanical barrier against coronal fistula formation in 16 subcoronal hypospadiacs aged 3-12 years who underwent Snodgrass tubularized incised plate urethroplasty. None had complications at 1-year of follow-up.
