Doctors do not recommended dialysis until a person has only 10 to 15 percent of his kidney function remaining, states the National Kidney Foundation. A person with stage 3 kidney disease still has 30 to 59 percent of his kidney function, according to Guy's and St Thomas' NHS Foundation Trust.
There are five stages of chronic kidney disease, explains WebMD. Staging is based on glomerular filtration rate, a measure of how quickly the kidneys are able to filter waste products and fluid from the blood. Stage 3 kidney disease is characterized by kidney damage with moderately reduced kidney function. A person with stage 3 kidney disease should be monitored regularly and treated for complications as necessary.
Dialysis is not indicated until someone enters kidney failure, reports WebMD. Dialysis filters fluid and waste products out of the blood, doing the work of the damaged kidneys, explains the National Kidney Foundation. Before undergoing hemodialysis, a person with kidney failure must have minor surgery to create access for the dialysis tubing. During a hemodialysis session, blood leaves the body via one tube and enters the dialysis machine. The machine filters the blood before returning it to the body via the other tube. A person in kidney failure usually receives dialysis treatments three times per week.
