title: Management of ileal conduit stomal obstruction: a urodynamic study.
abstract: Urodynamic perfusion studies have shown that edema or incrustation and ulceration may produce stomal obstruction in patients with ileal conduits. High emptying pressures may be present before there is any increase in the residual or conduit capacity, or before upper tract deterioration has occurred. Nine patients with early stomal obstruction were treated medically with acidification of the urine in the collecting bag and were compared to 6 patients who had stomal obstruction owing to irreversible changes and who were treated by surgical revision. In both groups emptying pressure returned to normal after treatment.
