A urostomy is a surgical procedure which diverts the normal flow of urine from the kidneys and ureters into a specially created stoma. To create the stoma the surgeon will isolate a short piece of your small intestine from which a tube or spout (known as a ileal conduit) will be created. The two ureters will be plumbed into this spout which will be brought to the surface of the abdomen. Urine will continue to pass through the stoma, completely bypassing the bladder. The bladder may or may not be removed. A urostomy is permanent.
