General Illness Information
Kidney Infection, Acute (Pyelonephritis, acute)
Common Name: None Specified
Description: Pyelonephritis is a bacterial infection of the kidney. It can be serious because of the important function of the kidneys and because the infection may enter the bloodstream. In women who are pregnant it may cause premature labor.
Kidney infections are much more common in women than men.
Causes: Most kidney infections result from lower urinary tract infections, usually bladder infections. Bacteria can travel from the vagina or anus into the urethra and bladder. Because of the location and size of their urethra, women are more prone to have bladder infections than men. In both men and women, lower urinary tract infections may spread to the kidneys, causing pyelonephritis.
Congenital abnormalities of the genito-urinary system and also kidney stones can predispose people to get pyelonephritis.
Prevention: For females:
- After bowel movements, always wipe from the vaginal area toward the rectum (front to back).
- Urinate within 15 minutes after sexual intercourse.
- Don’t hold urine; when you have the urge to void, do so.
- Increase fluid intake.
- Avoid bubble baths.

Diagnosis & Treatment
