How much is enough Dialysis?
Hemodialysis treatments usually last about 3 1/2 to 4 hours, and they are done three times a week.
Your doctor will give you a prescription that tells you how much treatment you need. Studies have shown that getting the right amount of dialysis improves your overall health, keeps you out of the hospital and enables you to live longer. Your dialysis care team will monitor your treatment with monthly lab tests to ensure you are getting the right amount of dialysis. One of the measures your dialysis care team may use is called urea reduction ratio (URR). Another measure is called Kt/V (pronounced kay tee over vee). Ask your dialysis care team what measure they use and what your number is.
Our goal is: URR >65% or Kt/V above 1.2
I feel fine, why should I check my URR?
In the short run, some people may feel okay without adequate dialysis. In the long run, not getting enough causes complication and leads to higher risk factors (infections, anemia, cardiac complications).
What if my URR is not enough?
Your adequacy can be improved in a few ways. The dialyzer filter can be changed to a large more efficient dialyzer for you. The blood flow to your access can be increased. Your access can be improved from a catheter to a fistula or a graft. If these donít work to improve your URR or Kt/V, your time can be increased.
There are some studies that show patients who get more dialysis time feel better, eat better and are more active.
