Peritoneal dialysis
After a few hours, the solution, along with the accumulated waste, is drained from the belly into an empty bag. The used solution can be disposed of in a toilet or tub. The process is then repeated with a fresh bag of dialysis solution. Fresh solution exhibits a higher efficiency in waste absorption, but over time, its filtering ability decreases. Hence, the process of emptying the used solution and refilling the belly with fresh solution needs to be repeated four to six times daily, which is referred to as an exchange.
