Pyonephrosis (Greek pyon "pus" + nephros "kidney") is an infection of the kidneys' collecting system. Pus collects in the renal pelvis and causes distension of the kidney. It can cause kidney failure.[1]

Signs and symptoms

The clinical presentation of an affected individual is, but not limited to the following:[2]

  • Painful urination
  • Fever
  • Nausea

Cause

Pyonephrosis is sometimes a complication of kidney stones, which can be a source of persisting infection. It may also occur spontaneously. It can occur as a complication of hydronephrosis or pyelonephritis.[citation needed]

Diagnosis

CECT is investigation of choice.

Treatment

This requires drainage, best performed by ureteral stent placement or nephrostomy.[citation needed] Surgery - Nephrectomy, if the ureter affects - Nephroureterectomy. If the second kidney is not healthy, only drainage of the kidney or puncture nephrostomy is performed.
