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
