Infection: a medical condition resulting from the presence of bacteria or other germs.
Inflammation: swelling, redness, and pain resulting from irritation or infection.

Prostate: walnut-sized gland in the male reproductive system that produces fluid for semen.
Pyelonephritis: an infection of the kidney(s).
Back to topRecurrent UTI: urinary tract infection that returns after the initial infection is treated, but is caused by a new strain or type of bacteria (different from the original one).
Relapse: urinary tract infection that returns after the initial infection is treated and is caused by the same infecting bacteria as the original infection.
Back to topSexually transmitted disease (STD): any disease transmitted by sexual contact, which is either caused by microorganisms that survive on the skin or mucous membranes of the genital area, or transmitted through semen, vaginal secretions, or blood during intercourse.
Susceptibility: a test to determine the activity of antibiotics against microorganisms that have been isolated and identified from cultures. (May be performed in conjunction with urine culture.)
Sterile: free of bacteria or other germs (organisms).
Suprapubic tenderness: uncomfortable pressure above the pubic bone.
Systemic: relating to the whole body.
Back to topUncomplicated UTI: urinary tract infection that develops in people who are otherwise healthy and have no urinary tract abnormalities.
