A nephron is a very thin tube that collects blood and filters out a variety of impurities. This is the process that leads to the creation of urine. In some individuals this process does not function properly. Doctors call this dysfunction renal parenchymal disease, but it is not really a single disease. It is a condition that stems from a variety of other causes, such as polycystic kidney disease, interstitial nephritis and hydronephrosis. These are not the exclusive causes.
