neobladder
Pronunciation: NEE-oh-blad-der
Continent urinary reconstruction using intestinal tissue to create a new bladder reservoir after cystectomy.
Full Definition
A continent form of urinary reconstruction performed after radical cystectomy, involving the use of intestinal segments (typically ileum) to create a spherical, low-pressure reservoir that replaces bladder function. The neobladder is anastomosed to the urethra, allowing patients to void through the urethra and maintain continence. Various techniques exist, including the Studer, Hautmann, and T-pouch procedures. Patient selection requires adequate renal function, sufficient urethral length, absence of urethral malignancy, and ability to perform clean intermittent catheterization if needed. Complications may include incontinence, retention, metabolic acidosis, and urethral stricture.
Usage
Usage note: Specify technique when known; emphasize continent nature and distinguish from conduit diversions.
