Q

what does a U/A or dipstick detect?

A
  • Leukocyte esterase
  • Enzyme released by leukocytes -> reflects pyuria
  • Nitrites

Presence of enterobacteria -> converts urinary nitrate into nitrite
-False positives with bladder analgesics (Ex: Phenazopyridine - pyridium)

-WBC, RBC, Protein

Q

most common pathogen for pyelonephritis?

17
Q

other pathogen for pyelonephritis? (HINT: think common in healthcare)

A

pseudomonas -> someone with indwelling catheter

18
Q

pathogenesis of pyelonephritis?

A
  • Begins with colonization of the vaginal introitus with fecal flora
  • Ascends into bladder, ureters, kidney
  • Can have seeding from bacteremia
19
Q

pyelonephritis signs and sx’s

A

UTI sx’s but more body sx’s - these people are much more sick!!!

Dysuria, Frequency, Urgency, Suprapubic pain, Hematuria

Fever, Chills, Flank pain, CVA tenderness, Nausea/Vomiting

20
Q

pyelonephritis labs?

A

U/A, urine culture, CBC (elevated w/left shift)

Blood cx - sepsis

21
Q

imaging for pyelonephritis?

A

none unless think there is a renal mass, then get renal US

22
Q

indications for hospitalizations for pyelonephritis

A

fever hasn’t gone down, sepsis, unable to take meds PO, urinary tract obstruction

23
Q

pyelonephritis treatment?

A

Fluoroquinolones (only PO recommendations for outpatient)
-Cipro, Levo

Alternative Treatments:
-Bactrim PO, Augmentin PO, Cefpodoxime PO

24
Q

symptomatic tx for pyelonephritis?

A
  • Phenazopyridine
  • Motrin, acetaminophen
  • Anti-emetics -> Zofran
  • IV fluids
25
acute cystitis in pregnant women and pyelonephritis in pregnant women are considered what?
complicated
26
signs and sx's of acute cystitis in pregnant women?
usually asymptomatic (but still get treated)
27
what are you looking for in UA's for UTI and pregnancy?
Looking for ketones b/c babies don't like ketones
28
outpatient treatment for UTI and pregnancy?
- Macrobid - Augmentin - Cefpodoxime - Fosfomycin
29
what meds should be avoided in the treatment of UTI and pregnancy?
FLUOROQUINOLONES!!!
30
UTI in pregnancy usually due to what?
anatomic changes during pregnancy Pressure on bladder, increase in size of ureters due to smooth muscle relaxation, immunosuppression
31
traditionally treated UTI in pregnancy for how long?
24 hours
32
inpatient tx's for UTI in pregnancy?
- IV beta-lactams - Penicillin derivatives - Cephalosporins (Cefazolin; Ceftriazone)
33
what is asymptomatic bacteriuria?
UTI found w/out sx's
34
what is urine normally in asymptomatic bacteriuria?
sterile
35
prevalence of asymptomatic bacteriuria increases with?
age -Elderly walking around with UTIs and don't know it
36
asymptomatic bacteriuria most common in?
pregnant women
37
asymptomatic bacteriuria tx?
- Appropriate to treat and screen in pregnant women and patients undergoing urologic procedures - Use of antibiotics same as cystitis - Don't treat the elderly, but will treat pregnant women
