A surgically constructed urinary reservoir, usually made from a segment of small bowel, that is used to replace a bladder removed during radical cystectomy. It is surgically connected to the patient’s native urethra and typically maintains urinary continence, while limiting or eliminating the need for self-catheterization. Neobladders are often used after bladder cancer surgery as an alternative to a urostomy. They cannot be used in patients whose malignancy involves the distal urethra.
A term used to describe the formation of a urine reservoir constructed from intestinal tissue, enabling excretion.
