Undiverting the ileal conduit.

From 1975 to 1981, 46 patients were evaluated for urinary undiversion. Of these patients 27 completed urinary reconstruction. The patients have been followed for 6 to 80 months, with a mean followup of 32 months and a median followup of 23 months. There has been no death and no rediversion has been necessary, although in 1 patient renal function has deteriorated significantly following urinary reconstruction. Postoperative bladder function was normal in patients diverted for dysfunctional voiding or bladder outlet obstruction but children with meningomyelocele required intermittent catheterization postoperatively. With careful patient selection, meticulous surgical technique and compulsive followup urinary undiversion is a safe procedure.
