Acute glomerulonephritis (AGN) is an inflammation of the glomeruli in the kidneys that can result from infections or injuries. There are two types: focal affects some glomeruli while diffuse affects all glomeruli and can lead to renal failure. Diseases that can cause glomerulonephritis include various types of vasculitis, lupus, and immunoglobulin A nephropathy. Acute renal failure (ARF) is the rapid loss of kidney function that occurs when waste builds up due to kidney damage or blockages. There are three types of ARF based on the cause: pre-renal from low blood flow, post-renal from blockages
