continent urinary reservoir
Surgically created internal pouch for urine storage that can be emptied by catheterization through a valve mechanism.
Full Definition
A continent urinary reservoir is a surgically constructed internal urine storage system created from bowel segments, designed to maintain continence through an anti-reflux valve mechanism. These reservoirs are typically created for patients requiring cystectomy or those with congenital abnormalities affecting bladder function. The construction involves creating a low-pressure, high-capacity pouch using intestinal segments, with a catheterizable channel that incorporates a continence mechanism to prevent spontaneous leakage. Common types include the Indiana pouch, Kock pouch, and Penn pouch, each with specific technical variations. Patients empty the reservoir by periodic catheterization through the abdominal stoma.
Usage
Usage note: Specify type (Indiana, Kock, Penn) when documenting specific reservoir construction.
