Three common types of urinary diversion?

• A. Colostomy, Ileostomy, Nephrostomy
• B. Sigmoidostomy, Jejunostomy, Enterostomy
• C. Urostomy, Ureterostomy, Vesicostomy
• D. Vesicostomy, Colostomy, Ileostomy

Answer: (C)

Urinary diversions redirect urine away from the bladder to an opening on the abdomen so urine can be collected in a bag. The three commonly discussed types are:

• Urostomy: a stoma created for urine to exit the body, usually after the bladder is removed or not usable. The urine is diverted through a conduit (often an ileal conduit) to a skin opening with a collection pouch.

• Ureterostomy: urine is redirected directly from the ureters to the skin surface, bypassing the bladder altogether. This creates one or two stomas for urine drainage.

• Vesicostomy: the bladder itself is brought to the abdominal wall to drain urine through a stoma, which can be temporary or for specific pediatric or clinical situations.

Other options like colostomy or ileostomy involve fecal drainage, and nephrostomy drains urine directly from the kidney without a skin stoma designed for long-term urinary diversion. The listed three are the urinary diversions that involve creating a skin-stoma for urine flow.
