neobladder

neobladder

 [ne″o-blad´er]
a continent urinary reservoir made from a detubularized segment of bowel or stomach, with implantation of ureters and urethra; used to replace the bladder after cystectomy.

ne·o·blad·der

(nē'ō-blad'ĕr),
Surgically constricted (usually using stomach or intestine) replacement for urinary bladder.

neobladder

A urinary diversion (UD) procedure in which a diseased bladder is replaced with one created from intestine that empties via the urethra.

Pros
Similar to natural voiding (i.e., best quality of life compared to other forms of UD); considered the procedure of choice for selected patients with bladder cancer; post surgery, voiding/urinating is relearned.
 
Cons
High rate of complications; complete emptying of the neobladder may require catheterization at the end of each void; careful patient selection is mandatory.
