Following ureterostomy, urine needs to be collected in bags. Several designs are available. One popular type features an open bag fitted with an anti-reflux valve, which prevents the urine from flowing back toward the stoma. A urostomy bag connects to a night bag that may be attached to the bed at night.
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, congenital defects that cause urine to back up into the kidneys, or urinary incontinence.
A common feature of the three first, and most common, types of urinary diversion is the ureteroenteric anastomosis. This is the joining site of the ureters and the section of intestine used for the diversion.
The tube in (A) and the pigtail in (B) are marked with white arrows. [ 1 ] A nephrostomy or percutaneous nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system ( renal pelvis ). [ 2 ]
Surgical procedures that involve the creation of an artificial stoma have names that typically end with the suffix "-ostomy", and the same names are also often used to refer to the stoma thus created. For example, the word "colostomy" often refers either to an artificial anus or the procedure that creates one.
A tube is typically also placed in the urethra or through a suprapubic opening to ensure full urine drainage and to rest the bladder during recovery. [25] The tubes are generally removed and the channel is ready to use with intermittent catheters in 4–6 weeks, [25] provided that a medical professional first instructs on how to catheterize. [23]

Ureterocutaneostomy is a type of incontinent, cutaneous urinary diversion.It provides a basic urinary diversion for preventing ureteral obstruction.Ureterocutaneostomy is usually preferred in infants/children as a temporary diversion whose metabolic status is inadequate for reconstructive surgery or palliative care of bladder carcinoma patients.
