Treatment:

Treatment of a perirenal abscess includes drainage of the pus, either by a catheter placed through the skin or via surgery. Antibiotics should also be given, initially through a vein (IV).

Expectations (prognosis):

In general, prompt diagnosis and treatment of perirenal abscess should lead to a good outcome. If present, kidney stones must be treated to avoid further infections.

In rare cases, infection can spread beyond the kidney area and into the bloodstream, which can be deadly.

Complications:

A possible complication is a continuing infection, if kidney stones are present.

Calling your health care provider:

Call your health care provider if you have a history of kidney stones and develop a fever, chills, burning with urination, or abdominal pain. Also call if you develop a urinary tract infection.
