D. A small urine reservoir is surgically created from a short piece of small intestine. The ureters are attached to one end of this piece. The other end is brought out through a stoma.
Explanation:
An ileal conduit surgery, also known as a urostomy, is meant to create an artificial opening called stoma, for diverting the urine of an individual where normal drainage through the bladder and/or urethra is not feasible.
The literal meaning of the term comes from ileum (referring to the last part of the small intestine that connects to the large intestine) and conduit (meaning a channel to aid the flow of a fluid, here, urine).
In this surgery, a small portion of the small intestine (ileum) and attached near the surface of the patient's abdomen through an artificially created opening (stoma). The ureters are attached to the other end. The passage of the urine is now: kidneys --> ureter --> ileal conduit --> stoma --> urostomy bag (collecting pouch attached at the outer end).
