What is augmentation cystoplasty?

Augmentation cystoplasty, also known as bladder augmentation, is a surgery to make the bladder larger. (The bladder is the organ that holds urine.)

Why is augmentation cystoplasty performed?

Augmentation cystoplasty is performed in people who have trouble urinating because of certain health problems or conditions. These include the following:

  • Incontinence, the inability to hold urine (wetting).
  • The muscles of the bladder are not working properly. For instance, the bladder may not stretch normally, which increases pressure in the bladder. This may cause pressure to back up to the kidneys (reflux), which can cause kidney infections and damage the kidneys. Augmentation cystoplasty can decrease pressure in the bladder.
  • Spasticity (stiffness) of the bladder.
  • Shrinking of the bladder caused by treatments (e.g., radiation) or diseases (e.g., spinal cord injury).

In many cases, augmentation cystoplasty is performed after the patient has performed self-catheterization for a period of time. Self-catheterization is a procedure in which the patient inserts a catheter (a thin, hollow tube) through his or her urethra (the tube through which urine comes out of the body) in order to drain urine.

How is augmentation cystoplasty performed?

Augmentation cystoplasty is a type of abdominal surgery, which means that the surgeon makes an incision (cut) in the patient’s abdomen to get to the bladder (Figure 1).

After making the incision in the abdomen, the surgeon cuts open the bladder at the top to prepare it for enlarging (Figure 2).

The surgeon then removes a section of the small or large intestine (Figure 3); detubularizes (cuts open) that link of bowel (Figure 3), and attaches it to the top of the bladder (Figure 4). The bladder and bowel are then sewn together to make the bladder larger (Figure 5).
