When bladder cancer is invasive, all or part of the bladder may need to be removed. This operation is called a cystectomy.
Partial cystectomy: If cancer has invaded the muscle layer of the bladder wall but is not very large and only in one place, it can sometimes be removed along with part of the bladder wall without taking out the whole bladder. The hole in the bladder wall is then closed. Nearby lymph nodes are also removed and examined for cancer spread. Only a small portion of people with cancer that has invaded the muscle can have this surgery.
The main advantage of this surgery is that the person keeps their bladder and doesn’t need reconstructive surgery (see below). But the remaining bladder may not hold as much urine, which means they will have to urinate more often. The main concern with this type of surgery is that bladder cancer can still recur in another part of the bladder wall.
Radical cystectomy: If the cancer is larger or is in more than one part of the bladder, a radical cystectomy will be needed. This operation removes the entire bladder and nearby lymph nodes. In men, the prostate and seminal vesicles are also removed. In women, the ovaries, fallopian tubes (tubes that connect the ovaries and uterus), the uterus (womb), cervix, and a small portion of the vagina are often removed along with the bladder.
General anesthesia (where you are in a deep sleep) is used for either type of cystectomy.
Typically, these procedures are done through a cut (incision) in the abdomen. You will need to stay in the hospital for about a week after the surgery. You can usually go back to your normal activities after several weeks.
In some cases, the surgeon may operate through several smaller incisions using special long, thin instruments, one of which has a tiny video camera on the end to see inside the pelvis. This is known as laparoscopic, or “keyhole” surgery. The surgeon may either hold the instruments directly or may sit at a control panel in the operating room and maneuver robotic arms to do the surgery (sometimes known as a robotic cystectomy). This type of surgery may result in less pain and quicker recovery because of the smaller incisions. But it hasn’t been around as long as the standard type of surgery, so it’s not yet clear if it is equally as effective.
It is important that any type of cystectomy be done by a surgeon with experience in treating bladder cancer. If the surgery is not done well, the cancer is more likely to come back.
