ureterostomy [u-re″ter-os´tah-me]

creation of a new outlet for a ureter.

cutaneous ureterostomy a type of urinary diversion in which one or both ureters are detached from the bladder and brought through the abdominal wall to form a stoma. A collection pouch fitted with a belt is then worn snugly against the abdomen and over the “ureteral buds” or stomas to collect the urine as it passes through the ureters.



Indications for ureterostomy include malignancy or trauma that necessitates removal of the bladder, congenital defect or absence of portions of the urinary tract, and neurogenic bladder in which other devices for the collection of urine have proved unsatisfactory.

Patient care is similar to that for any patient with a diversion of urinary flow and is primarily concerned with teaching the patient how to care for the appliance and avoid complications arising from the creation of the stoma. See also ileal conduit.

Cutaneous ureterostomy. From Lammon et al., 1995.
