[citation needed] There are four common types of ureterostomies:[citation needed] Ureterostomy patients may have the following tests and procedures as part of their diagnostic work-up: The quality, character, and usable length of the ureters is usually assessed using any of the following tests: The pre-surgery evaluation also includes an assessment of overall patient stability.

One popular type features an open bag fitted with an anti-reflux valve, which prevents the urine from flowing back toward the stoma.

The adhesive does not need to be removed frequently from the skin, and can remain in place for several days while the bag is changed as required.

Risks during surgery include heart problems, pulmonary (lung) complications, development of blood clots (thrombosis), blocking of arteries (embolism), and injury to adjacent structures, such as bowel or vascular entities.

If plastic tubes need inserting, their malposition can lead to obstruction and eventual breakdown of the opening (anastomosis).

Normal results for a ureterostomy include the successful diversion of the urine pathway away from the bladder, and a tension-free, watertight opening to the abdomen that prevents urinary leakage.

They reported one complication per four patients (6.3%), including a case requiring open drainage, prolonged urinary leakage, and common ureteral death (necrosis).
