A replacement bladder can potentially be created by your surgeon. This is known as bladder reconstruction or neobladder surgery. Your doctor will use a section of your colon to form a sac-like structure similar to your previous bladder. It can store pee, which implies you should be able to pass urine as previously. However, the urine may contain bacteria that enter your bloodstream through open wounds in your abdomen. This could lead to infection of your new bladder. Further, there is no muscle tissue in the colon that can help it contract like normal bladder tissue can. So when you go to the bathroom, the colon has nothing to do with how full your body gets. It leaks urine and loses water. Instead, the surgeon will attach blood vessels from other parts of your body to the colon portion that will function as the new bladder. The vessels supply blood to the colon segment, which grows in size over time. This procedure is done while you are under general anesthesia. You will spend the night in the hospital after this operation. You need to know that this type of surgery is considered major abdominal surgery and is very risky. There is a very good chance that you will die during this operation or soon after it. In fact, the mortality rate for this procedure is about 10 percent. This means that one out of ten people who have this surgery will not live beyond two years.
