I am trying to understand how urostomy (or ileal conduit) works. ureter is a sterile environment. what keeps bowel content from leaking into the ureter? thanks.

The ileal conduit is just a piece of the small intestine cut away and used do divert the urine by attaching the ureters to it and then the other end as a stoma. It isnt attached to the GI system at all, just borrowed a piece of it as path for urine to exit the body, does that make sense?

So the 3rd pic from the left (Cleveland Clinic source) shows it for you - like PP said, it's a total bypass.

that bit of bowel is no longer in the bowel-- they take a bit out, sew the remaining bowel back together to go back about its normal business, then use the section they took out to become the ileal conduit.

I get it now. thank you.

I had the same question. Thanks for posting!
