UTIs Flashcards
urinary tract infection
bacterial colonization of lower urinary tract with characteristic clinical signs
cystitis
bladder inflammation
bacterial cystitis
bacterial bladder infection
subclinical bacteriuria
presence of bacteria in urine (positive urine culture) without clinical signs
is subclinical bacteriuria more common in cats or dogs
dogs - usually with concurrent comorbidities
RARE in cats
is subclinical bacteriuria commonly treated
no - usually no treated unless it is a urease producing bacteria, systemic disease, or azotemic
hematuria
blood in the urine
pollakiuria
small amounts of urine, frequently
dysuria
painful urinations
periuria
inappropriate urinations
stranguria
straining to urinate
polyuria
increased volume of urine
urinary incontinence
unconscious urine leaking (increased sense of urgency)
is systemic disease a sign of a UTI
NO - a sign of pyelonephritis or prostatitis
sporadic bacterial cystitis
three or less UTIs in one year
NO known urinary tract/systemic comorbidities
recurrent UTIs
greater than three UTIs in one year
often associated with comorbidities
can be reinfection or relapse
reinfection vs relapse
reinfection: urinary tract was sterile then reinfected with NEW organisms
relapse: (persistent) urinary tract was NOT completely sterilized, recurs with the same organism
are UTIs more common in dogs or cats
dogs
what bacteria are dogs most susceptible to
E. coli
staphylococcus
what do cats with lower urinary tract signs typically have
feline idiopathic cystitis (FIC)
what are the physical exam findings of UTI
mostly normal - possibly thickened bladder, firm urethra, check prostate and vulva
defense against UTIs: urine
antimicrobial properties - high osmolality, highly acidic (low pH)
defense against UTIs: urethra
hydrokinetic washout
high pressure urination helps clear bacteria out from urethra
defense against UTIs: bladder
hydrokinetic washout, bactericidal (immunoglobulins)
