Skin flap technique in formation of urinary conduit stoma

Island pedicle graft in stomal stenosis: a new technique

Pinpoint obstructive stenosis of the urinary stoma was treated in 5 patients after ileal conduit urinary diversion and in 2 with cutaneous ureterostomy. All 7 patients underwent a single-stage stomal revision with the use of 1 or more island pedicle skin grafts to increase stomal diameter. In each instance the stomal opening was enlarged sufficiently to relieve obstruction and morbidity. During patient followup from 18 months to 7 years no revised stoma has required subsequent intubation nor has stenosis recurred.
