Question: what is the difference between pyelonephritis and glomerulonephritis?
Answer: Pyelonephritis is characterized by the inflammation of the renal interstitium associated with the collecting system, renal calyces and renal pelvis but not the glomerular tissues. Pyelonephritis (PN) is the most common renal disease and, after chronic glomerulonephritis, the second most common cause of renal failure.
