(80 cards)
1
Q
urinary tract infection (UTI)
A
- involves any portion of the lower urinary tract (ureters, bladder, urethra, prostate)
- due to high virulence bacteria overcoming normal host bacteria
- may also be due to immunocompromised host
2

- prostatitis
3
Q
upper UTI
A
•inflammation of kidney pelvis
Ex: pyelonephritis
4
Q
cystitis
A
