Kidney Flow
Renal Perfusion or an increase in kidney blood flow is the earliest sign that a treatment for PKD is working. This is the outcome from the CRISP study. The CRISP study determined what doctors could follow to determine if a treatment was working for PKD polycystic kidney disease. Prior to the CRISP study researchers had to wait 20 years or more to see if something worked or not.
Body position increases renal perfusion also certain blood pressure medications aides kidney blood flow. An MRA study with gadolinium was used to detect renal perfusion however gadolinium is no longer used with PKD patients or Chronic Kidney Disease CKD patients. A warning was issued by the FDA. Laying down helps perfuse the kidneys with blood. Taking adequate rest helps increase the blood flow to cystic kidneys.
