Ileal substitution bladder can be used for life. Ileal Substitute Bladder is an excellent substitute bladder approach for bladder tumors, which has very few complications, low likelihood of bilateral ureteral stenosis, generally does not tend to lead to fluid retention in the kidneys, effectively reduces acidosis, and stores urine formed by the kidneys in the substitute bladder to achieve the function of urinary control. The ileal pronephric bladder can be used continuously as long as there is no tumor invasion or no obstruction. In the case of obstruction of the ileal pronephric bladder, it is recommended that bilateral ureteral stenting tubes be implanted under the guidance of ureteroscopy, which can effectively improve the function of drainage of urine.
