There are 2 general types of kidney disease - one is Chronic Kidney Disease (CKD) which is caused by the usual things like diabetes, high blood pressure, arteriosclerosis, polycystic kidney disease, etc. and then there is Acute Kidney Disease (AKD) which is caused by trauma, medications, extreme blood loss, etc. Acute Kidney Disease can require dialysis temporarily but then, because it is acute, kidney function can resume.
