ileal conduit
Pronunciation: IL-ee-al KON-doo-it
Urinary diversion technique using a segment of ileum to create a conduit between ureters and abdominal wall stoma.
Full Definition
An ileal conduit is a type of urinary diversion procedure commonly performed after radical cystectomy for bladder cancer. This technique involves harvesting a 15-20 cm segment of terminal ileum, which is then configured as a conduit to connect the ureters to a stoma on the abdominal wall. The ileal segment is not used as a reservoir but simply as a conduit for urine flow, requiring external collection with an appliance bag. While considered the gold standard urinary diversion for many years, the ileal conduit has been associated with long-term complications including stomal problems, metabolic acidosis, and upper tract deterioration. Alternative diversions include continent urinary diversions and orthotopic neobladders, though patient selection depends on various factors including cancer stage, patient age, and functional status.
Usage
Usage note: Note spelling 'ileal' (relating to ileum) not 'ileac' (relating to iliac).
