symptoms persist after 48-72 hours of appropriate antibiotics
recurrent symptoms within a few weeks of TX
urinary analgesics
may mask S&S of UTI's that don't respond to therapy. little clinical role because pt's respond quickly to antimicrobial therapy
alternate therapies with little efficacy results
cranberry juice
topical estrogens
lactobacilli

3 drugs for uncomplicated cystitis Tx - first line
nitrofurantoin - 5 days
Bactrim - 3 days
fosfomycin - 1 dose
second line options for uncomplicated cystitis Tx
fluoroquinolones - 3days
levofloxacin - 250-500mg QD
ciprofloxacin - 250mg bid
ciprofloxacin ER - 500mg QD
beta-lactams - 3-7days
augmentin
cefaclor
cepodoxime
4 general rules of complicated cystitis
individualize Tx
always culture and narrow therapy based on
worry about more pathogens
longer duration of Tx 5-14 days
PO options for complicated cystitis - empirical therapy
fluoroquinolones
levofloxacin - 750mg QD - 5 days
ciprofloxacin - 500mg BID - 7-14 days
ciprofloxacin ER - 1g QD - 7-14 days
IV options for complicated cystitis - empirical therapy
levofloxacin - 500-750mg - 5days
ceftriaxone - 1000mg daily - 10-14 days
carbapenems - 1000mg QD - 10-14 days
aminoglycosides - 7mg/kg QD - 10-14 days
gentamicin
PO Tx for pyelonephritis
fluoroquinolones

symptoms of UTI
7 S&S of CA-UTI
fever
chills
altered mental status
malaise
flank pain
costovertebral angle tenderness
pelvic discomfort
3 signs that aren't indicative of CA-UTI
odorous urine
cloudy urine
pyuria
2 points on CA-UTI cultures
don't draw unless symptomatic
obtain culture prior to Tx
culture from fresh catheter
organisms - polymicrobial & multidrug resistant pathogens
4 guides when choosing an antibiotic for CA-UTI
severity of infection
local resistance patterns
culture results
choice is usually similar to Tx of complicated UTI
Tx durations for CA-UTI
typically 7-14 days
7days if respond to initial Tx
10-14 days if delayed response to initial Tx
Levofloxacin - 5 days may be adequate
Diagnosis of asymptomatic bacteruria in men and women

who do we screen for asymptomatic bacteruria
pregnant women - 1 screen early in pregnancy
prior to urologic procedures
who don't we screen for asymptomatic bacteruria
pre-menopausal, non-pregnant women
diabetic women
older adults (community and institutionalized)
spinal cord injuries
catheterized pts
when would pyuria be an indication for Tx of asymptomatic bacteriuria
children
pregnancy
treat 3-7 days
followed by periodic screening for reoccurence
certain urologic procedures (TURP)
initiate shortly prior to procedure
only continue if catheter remains
catheter-acquired bacteriuria persisting 48 hours after removal of catheter
Tx for UTI's in pregnancy
cephalosporins 5-7 days
nitrofurnatoin 5-7 days
augmentin 5-7 days
2nd line - Bactrim 5-7 days
is there a cephalosporin to avoid in pregnancy and why
ceftriaxone - kernicterus
nitrofurantoin in pregnancy
avoid use after 37 weeks due to hemolytic anemia
Bactrim in UTI in pregnancy
avoid in 1st trimester due to CV malformations
avoid in last weeks of pregnancy due to kernicteus
differentiate between reinfection and relapse in terms of when occurs
reinfections - > 14 days after last UTI
relapses - within 14 days
7 behavioral tips for preventing reinfections
less sex
avoid spermicides
pee after sex
fluids
no jungle wiping
avoid douching
avoid tight fitting underwear
3 biologic mediators for the prevention of reinfections
cranberry
topical estrogen
D-mannose
prophylactic antimicrobials for reinfections in women
if they have had
3 or more UTI's in the past 12 months
2 or more UTI's in the past 6 months
must be confirmed by urine culture
single dose prophylaxis regimens for UTI's
Bactrim 1/2 SS tablet x 1 dose
TMP 100 mg x 1 dose
nitrofurantoin 50-100mg x 1 dose
cephalexin 250 mg x 1 dose
continuous prophylaxis for UTI's
bactrim 1/2 SS tab QD or 3 times weekly
levofloxacin 500 mg QD
nitrofurantoin 50-100mg daily
TMP 100 mg QD
duration and follow up of continuous prophylaxis fo UTI's
continue antibiotics for mo. then observe
may follow urine cultures monthly
if symptoms develop, pt should be treated for UTI
7 S&S of prostitis
fever
chills
malaise
myalgia
dysuris
pelvic or perineal pain
cloudy urin
microorganisms of prostitis
E.coli - 50-80 % of all cases
klebsiella
proteus
enterococcus sp.
pseudomonas sp.
acute prostatitis outpatient treatment
fluoroquinolones - 2-6 weeks
levo - 750 mg QD
cipro - 500 mg BID
cipro ER - 1G QD
bactrim - 2-6 weeks
160/800mg BID
general rule of switching from IV to PO meds for most conditions
