Overview
Pyonephrosis (Greek pyon "pus" + nephros "kidney") is an infection of obstructed renal collecting system leading to accumulation of pus in the renal collecting system. Pus collects in the renal pelvis and eventually causes destruction of the renal parenchyma[1]. Pyonephrosis is sometimes a complication of renal stones, which can be a source of persisting infection. It may also occur spontaneously.
It needs an early diagnosis and immediate intervention as it may progress to Urosepsis. Treatment may require drainage, best performed by nephrostomy.
Pathophysiology
Pyonephrosis can be seen as a complication of acute pyelonephritis, usually seen with complete or incomplete obstruction of tubules. Obstruction of ureter and renal pelvis causes dilatation of tubular system which in turn leads to hydronephrosis. The dilatation of the tubular system serves as a nidus for infection because the pathogens multiply easily in obstructed and dilated tubules leading to suppurative inflammation.
