Definition of "Cystectomy"
Last modified: 11 hours
It means surgical removal of some sort of bag. It usually refers to the bag which holds urine, the bladder. But it can also relate to a sac which holds fluid, called a cyst. Or the bag which holds bile, the gallbladder.
If it's got cancer.
. Does that mean that you'll need to pee as the kidneys create urine, which is... continuously 
?
Exactly. So that's why we might need to redirect the urine from the kidneys to a special section of the intestine that we detach for this purpose. So we can do this with a part of the small intestine, or the large intestine. We then either bring a section out so we can get rid of the stored urine, or we can get the patient to let the urine out with a straw, called catheterization. Later on, we can reattach it to the uterus and urethra. And using the original muscle control, we can empty the artificial bladder as we do normally.
Cystectomy (from Grek "kystis" meaning "pouch" or "bladder", "ektome" meaning "excision"
is surgical removal of all/part of the urinary bladder. Cystoprostatectomy is the combination of a cystectomy (removal of the urinary bladder), and a prostatectomy (removal of the prostate gland).
It can also rarely refer to removal of a cyst, or the gallbladder (i.e. where bile is stored after being produced by the liver).
Patient information
What is cystectomy?It means surgical removal of some sort of bag. It usually refers to the bag which holds urine, the bladder. But it can also relate to a sac which holds fluid, called a cyst. Or the bag which holds bile, the gallbladder.
The prostate is sometimes removed together with the bag that holds urine? Why, and what is it?
Because the prostate is located just underneath the bladder. The prostate is the gland which makes a milky alkaline fluid that makes semen alkaline.
Purpose
- Bladder cancer, most commonly
Patient information
Why on earth would you want to take out the bag that holds urine?If it's got cancer.
Method
- After the bladder is removed, an ileal conduit urinary diversion (i.e. diverts urine, where the ureters are surgically resected from the bladder, and a ureteroenteric anastomosis is made to drain the urine into a detached section of the small intestine, which itself is brought out through an opening in the abdominal wall) is necessary
- Alternatively, a pouch is constructed from a section of the ileum/colon, which can act as a form of replacement bladder, storing urine until the Pt desires to release it, which can be achieved by either abdominal straining or self catheterization
- Future Tx for this condition may involve a full replacement with an artificial bladder (aka neobladder), which involves a loop of intestine surgically fashioned into a pouch and placed in the location of the original bladder. It is then attached to the uterus and urethra, thus simulating the function of the original organ. They kidneys filter the urine into the neobladder which can often be emptied by muscle control

Wait. If the bladder holds urine, and you take that out. Houston, we have a problem. Does that mean that you'll need to pee as the kidneys create urine, which is... continuously ?Exactly.
