Renal. UTI (08-03) Flashcards

1
Q

FA. what is the way of UT infection?

A

Ascending

Urethra –> prostate (prostitis) –> bladder (cystitis) –> kidney (pyelonephritis) –> systemis (urosepsis)

Due to this ascention these infections share common microbiologic profiles.

Symptoms same as in uncomplicated.
Everything depends on populations which are at higher risk for complexity.

pregnant
patient with comorbidities (such as diabetes),
infants and toddlers, and male sex;

immu­nocompromise or stents or urinary catheters, as well as those with recurrent or refractory UTls

A complicated UTI would also be any patient with systemic symptoms of UTI that might suggest pyelo­ nephritis.
