Polycystic Kidney 1
Originally uploaded by Rev. Day-Bu.
A kidney damaged by Polycystic Kidney Disease. In a nutshell, PKD is a genetic disease in which cysts grow on the outside of the kidney. The cysts grow larger and larger, gradually damaging the kidney's filters which remove toxins from the bloodstream. PKD causes bad, constant pain, and ultimately--though it can take years--the kidney will fail.
