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.
Signs and symptoms
The clinical presentation of an affected individual is, but not limited to the following:
- Painful urination
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.
CECT is investigation of choice.
This requires drainage, best performed by ureteral stent placement or nephrostomy. Surgery - Nephrectomy, if the ureter affects - Nephroureterectomy. If the second kidney is not healthy, only drainage of the kidney or puncture nephrostomy is performed.
