Ileal trigonal urinary diversion: 5-year followup evaluation

We anastomosed the intact, undisturbed vesical trigone to the isolated ileal conduit in 24 patients, most of whom have been followed for 5 years. None of these patients has had any pyelographic evidence of upper tract deterioration. There have been no episodes of pyelonephritis, no hydronephrosis, no renal stones and only 4 of the 46 renal units have demonstrated reflux. These data indicate unsurpassed protection of the upper tracts in those patients with neurogenic bladder dysfunction.
