The use of small intestine in bladder reconstruction.

Reconstruction of the bladder is a treatment available to patients who have a diseased or damaged bladder, and small bowel is the most commonly used tissue. Augmentation cystoplasty increases the total bladder capacity, whereas substitution cystoplasty replaces the whole organ. This is either drained through a continent cutaneous stoma or is reanastomosed to the urethra as an orthotopic reconstruction. Although the treatment for invasive bladder cancer has not changed greatly in the last few decades, the use of orthotopic bladder reconstruction allows for a great improvement in the quality of life for patients who undergo cystectomy. These reconstructive techniques can also be offered to patients with other forms of pelvic malignancy that involve the bladder.
