Pathophysiology
Most perirenal abscesses are caused by urinary tract infections that start in the bladder, spread to the kidney, and then spread to the area around the kidney. Other causes of perirenal abscess include surgery in the urinary tract or reproductive system and bloodstream infection.
The primary pathogens involved in a kidney abscess include the following:
- Enterobacter species
- Escherichia coli
- Klebsiella species
- Proteus mirabilis
- Pseudomonas species
- Streptococcus faecalis
- Staphylococcus aureus
