catheterizable channel
A surgically created conduit from the bladder to the skin surface that allows intermittent catheterization while maintaining continence.
Full Definition
A catheterizable channel, also known as a continent catheterizable stoma, is a surgically constructed conduit that connects the bladder to the abdominal wall or other accessible location, allowing patients to perform clean intermittent catheterization while maintaining continence between catheterizations. Common techniques include the Mitrofanoff appendicovesicostomy (using appendix), Monti procedure (using small bowel), and Yang-Monti modification (using reconfigured bowel). These channels typically incorporate an antireflux mechanism and are essential for patients with neurogenic bladder, exstrophy-epispadias complex, or those who have undergone bladder neck reconstruction.
Usage
Usage note: Distinguish from simple urinary diversions; emphasize the continent nature of these procedures.
