How the urinary system normally works
When the body carries out its normal functions, waste materials collect in the blood. The blood is continuously filtered by the kidneys to remove the waste matter.
This produces urine, which moves from the kidneys via the ureters to the bladder where it is stored. Urine is passed from the bladder via the urethra.
With a urostomy
Instead of being passed via the bladder, urine comes down the ureters from the kidneys and is diverted to come out of an opening (stoma) in the abdomen. A watertight pouch is fitted over the stoma to collect the urine.
How the stoma is formed
The surgeon takes a small piece of the ileum (part of the small intestine) and uses it to create a tube or spout (called an 'ileal conduit').
The rest of the ileum is rejoined so that your digestive system works just as it did before.
The two ureters are diverted from the bladder and are ‘plumbed’ into the ileal conduit, which then opens onto the abdomen.
