Urostomy

A urostomy is a stoma (artificial opening) for the urinary system. A urostomy is made to avail for urinary diversion in cases where drainage of urine through the bladder and urethra is not possible, e.g. after extensive surgery or in case of obstruction.

Techniques

Techniques include:

• Ileal conduit urinary diversion, in which the ureters are surgically resected from the bladder and a ureteroenteric anastomosis is made in order to drain the urine into a detached section of ileum (a part of the small intestine). The end of the ileum is then brought out through an opening (a stoma) in the abdominal wall. The urine is collected through a bag that attaches on the outside of the body over the stoma.
• Indiana pouch

A "continent urostomy" is an artificial bladder formed out of a segment of small bowel. This is fashioned into a pouch, which can be emptied intermittently with a catheter. It avoids the need for a stoma bag on the urostomy.

Indications

Urostomy is most commonly performed after cystectomy, such as may be necessary in, for example, bladder cancer. Other indications include: Severe Kidney Disease; Accidental Damage or Injury to the urinary tract; Surgical Complications because of non-related pelvic or abdominal surgery; Congential defects that cause urine to back up into the kidneys; Continual and Severe Leakage from the bladder - incontinence.
