E3 UTI Flashcards
4 risk factors he told us to know for genitourinary infections
- urologic instrumentation and catheterization
- urinary tract obstruction
- neurogenic bladder
- renal transplantation
most common pathogen for every type of UTI
E COLI**
what are 2 bacterias that are common pathogens for complicated UTIs?
enterococcus
pseudomonas
clinical presentation of UTIs is very obvious so im just saying im not making shit for that
okay
T or F:
smelly or turbid piss is correlated with infection
false, this alone does NOT mean a UTI, some people might just have smelly piss
T or F:
hematuria can occur in some cases and is typically classified as a complicated UTI
FALSE AGAIN, this alone does not mean UTI
clinical pres, complicated UTI:
5 ish things?
- classic UTI sxs present but not always
- fever
- malaise
- altered mental status
- urinary incontinence
- change in appetite
4 things for clinical pres of complicated UTI - catheter-associated
- classic UTI sxs often NOT present
- pain over kidney and bladder
- fever
- lethargy/malaise
3 underlined things for diagnosis of UTI and pyelonephritis
cystitis sxs
pyelonephritis sxs
microbiologic criteria
what are the 4 cystitis sxs for diagnosis of UTI
- dysuria
- inc piss frequency
- inc piss urgency
- suprapubic heaviness/pain
what are the 3 pyelonephritis sxs for diagnosis of UTI
- fevers/chills/rigors
- CVA tenderness (flank pain)
- malaise
i have no idea wtf the microbiologic criteria stuff means for diagnosis of UTI so
yeah idk >10^5 of >1 bacterial species from a clean void
> 10^3 of >1 bacterial species from a catheter (placed in last 48 hours)
4 key components related to diagnosis of UTI for urinalysis
- bacteria present
- WBC present (>10 cells/hpf)
- leukocyte esterase present
- nitrite may or may not be present
what bacteria converts nitrates to nitrites?
enterobacterales ***
what are the 4 most commonly used drugs for UTI treatment
- nitrofurantoin*
- bactrim
- FQs -> cipro/levo
- fosfomycin
only used for uncomplicated UTIs
A. nitrofurantoin
B. bactrim
C. FQs -> cipro/levo
D. fosfomycin
A and D *
what are the 5 beta lactams that can be used for UTI tx
- cephalexin
- cefadroxil
- cefpodoxime
- amox/clav
- amoxicillin
which can only be used for UTI tx after susceptibility is confirmed
- cephalexin
- cefadroxil
- cefpodoxime
- amox/clav
- amoxicillin
amoxicillin alone
The threshold of __% is the resistance prevalence at which the agent is no longer recommended for
empirical treatment
20% *
duration of therapy for uncomplicated UTI
3-7 days
duration of therapy for complicated UTI
7-14 days
which of the following have a resistance rate to e/coli >20% and should not be used empirically
a. nitrofurantoin
b. bactrim
c. cipro
d. cephalexin/cefadroxil
e. cefpodoxime
f. amox/clav
B and C*
common drug options for empiric UTI tx in the hospital
- amp + gent*
- cefazolin +/- gent
- ceftriaxone
- cefepime

T or F:
if a pt is experiencing bacteremia w/ their UTI you should have a longer duration of tx
false
3 rec tx options for prostatitis
- FQs

what is the duration of tx for prostatitis
2-4 weeks damn
2 criteria for recurrent UTI *
- 3 or more infections in 1 year
- 2 or more infections in 6 months
T or F:
prophylactic antibiotic use is possible for recurrent UTIs
true
if he asks anything about which antibiotic to use to determine susceptibility of another the common choice was cefazolin
cool i’ll keep that in mind, thanks past cole
there were two drugs he said he hates for treating UTI what were they
cipro and cefdinir (dont pick these on the exam unless nothing else makes sense at all)
