Renal. UTI (08-03) Flashcards
FA. what is the way of UT infection?
Ascending
Urethra –> prostate (prostitis) –> bladder (cystitis) –> kidney (pyelonephritis) –> systemis (urosepsis)
Due to this ascention these infections share common microbiologic profiles.
FA. Cystitis presentation?
Dysuria, frequency, urgency, suprapubic pain, WBC in urine (BUT NOT WBC CASTS).
FA. fundamental Pyelonephritis symtoms?
CVA tenderness, flank pain
hematuria, WBC CASTS
Systemic symptoms: fever, chills
FA. Uncomplicated UTI criteria.
Lower UTI is acute, simple cystitis (symptoms in other card) in otherwise healthy, nonpregnant woman who has not failed a/b therapy
FA. Uncomplicated UTI treatment.
TMP-SMX for 3 days
Nitrofurantoin for 5-7 days - only for cystitis, if suspected pyelo, when clearance < 60 ml/min or complicated UTI, dont use nitrof.
FA. Uncomplicated UTI. When culturing?
ONLY when treatment failed
UW. Uncomplicated UTI. when avoid TMP-SMX?
When locaql resistance > 20 proc.
UW. Uncomplicated UTI. What single shot drug?
Fosfomycin single dose
UW. Uncomplicated UTI. When fluoroquinolones?
Only when previously mentioned options cannot be used (TMP-SMX, nitrof, fosfomycin)
FA. Complicated UTI. criteria? summarized
summarized: one that does not meet criteria for uncomplicated.
FA. Complicated UTI. criteria detailed.
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.
FA. Complicated UTI. treatment? stable
fluroquinolones, third-/fourth-generation cephalosporins,
or TMP-SMX
Peroral is hemodinamically stable and can be treated outpatient

Unstable hemodynamic - iv a/bs
IV third-/fourth-generation cephalosporins
typically given, or fluroquinolones

Fluoroquinolines (5-14 days)
extended spectrum eg ampic-sulbactam for more severe
UW. Complicated UTI. sampling
Obtain prior treatment and adjust ab if needed
UW. Uncomplicated UTI. nitrofurantoin complication HY?
Nitrofurantoin induced pulmonary injury 3-9days after drug + rashes + eosinophilia + lung findings

dont use fluoroquinolones
considercefpodoxime, cephalexin, amoxiclave, fosmomycin

what is routinely performed and why in pregnant?
Urinalysis is routinely performed to screen for asymptomatic bacteriuria
FA. pregnancy UTI. increased risk for what?
patients are at increased risk for pyelonephritis and urosepsis
FA. pregnancy UTI.
asymptomatic bacteriuria treatment?
normally does not require treatment;
BUT, due to increased risk for com plications, pregnant women with asymptomatic bacteria are treated with either nitrofurantoin
or amoxicillin
Treatment of cystitis and pyelonephritis would be as for
treatment of complicated UTI
FA. pregnancy UTI.

follow-up culture to confirm
resolution
