T

12

Most common serious bacterial infection in infants younger than 24 mo of age who have fever without an obvious focus

Clinical pyelonephritis

13

A renal mass caused by acute focal infection without liquefaction

Acute lobar nephronia

14

A rare type of renal infection characterized by granulomatous inflammation with giant cells and foamy histiocytes

Xanthogranulomatous pyelonephritis

15

Management for Xanthogranulomatous pyelonephritis

Partial or total nephrectomy

16

T/F Cystitis does not cause fever

T

17

Acute hemorrhagic cystitis often is caused by

E. coli

18

Acute hemorrhagic cystitis often is caused by E. coli has also been attributed to

Adolescent girls

20

Asymptomatic bacteriuria is most common in what gender

Female

21

T/F Asymptomatic bacteriuria does not cause renal injury

T, except in pregnant women in whom, if left untreated can result in symptomatic UTI

22

T/F Nearly all UTIs are ascending infections

T

23

Children of any age with a febrile UTI can have acute pyelonephritis and subsequent renal scarring, but the risk is highest in what age group

Younger than 2 years old

24

Risk factors for UTI

Female gender, Uncircumcised male, Vesicoureteral reflux*, Toilet training, Voiding dysfunction, Obstructive uropathy, Urethral instrumentation, Wiping from back to front in girls, Bubble bath?, Tight clothing (underwear), Pinworm infestation, Constipation, Bacteria with P (type II) fimbriae, Anatomic abnormality (labial
adhesion), Neuropathic bladder, Sexual activity, Pregnancy

25

In girls, UTIs often occur at the onset of toilet training because of

Bladder/bowel dysfunction that occurs at that age

26

T/F According to the 2011 American Academy of Pediatrics (AAP) Clinical Guideline for children 2-24 mo, in children who are not toilet trained, a catheterized or suprapubic aspirate urine sample should be obtained

T

27

T/F If the child is symptomatic, a UTI is possible, even if the urinalysis result is negative

T

28

T/F Infection can occur in the absence of pyuria

T

29

T/F Pyuria can be present without UTI

T

30

Sterile pyuria (positive leukocytes, negative culture) may occur in what conditions

1) Partially treated bacterial UTIs 2) Viral infections 3) Renal tuberculosis 4) Renal abscess 5) UTI in the presence of urinary obstruction 6) Urethritis as a consequence of a sexually transmitted infection 7) Inflammation near the ureter or bladder (appendicitis, Crohn disease), or 8) Interstitial nephritis (eosinophils)

31

T/F Refrigeration is a reliable method of storing the urine until it can be cultured

T

32

With a renal abscess, the white blood cell count is markedly elevated to ___

>20,000-25,000/mm3

33

T/F Sepsis is not common in pyelonephritis, hence blood cultures should not be drawn before starting antibiotics

F

34

Indication for hospitalization of child with UTI

Dehydrated, vomiting, unable to drink fluids, 1 mo of age or younger, complicated infection, urosepsis is a possibility

35

UTI: Treatment with ___ is particularly effective against Pseudomonas spp., and alkalinization of urine with sodium bicarbonate increases its effectiveness in the urinary tract.
