How many ureterostomy stomas are typically created?

• A. Two stoma sites on the right side
• B. Two stoma sites, one for each ureter
• C. Three stoma sites
• D. One stoma site on the left

Answer: (B)

Ureterostomy typically requires a stoma for each ureter, because each (kidney) ureter needs its own channel to drain urine to the outside of the body. When both ureters are diverted directly to the skin, you end up with two stomas—one opening for each ureter—usually placed on opposite sides of the abdomen for independent drainage and easier care. This setup contrasts with a urinary conduit, where the ureters drain into a single intestinal segment that exits through one stoma. So the common scenario is two stoma sites, one for each ureter.
