Urodynamic evaluation of patients with continent urinary diversion using cecal reservoir and intussuscepted ileocecal valve.

Patients requiring bladder removal for malignant disease have undergone continent urinary diversion employing the ileocecal segment, using the cecum to construct a reservoir and an intussuscepted ileocecal valve as the continence mechanism. Five of these patients have been studied urodynamically and radiographically in the postoperative period. Incontinence was found to be minimal and related only to a prolonged catheterization interval. Passive filling pressure and peristaltic pressure remained low in all patients and was lower than the nipple valve pressure in 4 of 5 patients. A transient increase in reservoir pressure at capacity with peristalsis exceeded the nipple peristaltic pressure in 1 patient and was associated with a small volume of incontinence. This resolved with a shortened catheterization interval. Reflux was not found in any subject studied. These studies indicate that the cecal segment can be used to construct a continent urinary reservoir that provides satisfactory function for the patient while maintaining an acceptable pressure volume relationship.
