What is vesicoureteral reflux (VUR)?
abnormal retrograde (backward) flow of urine from bladder into upper urinary tract
Any time there is stenosis of a ureter, what happens to the kidney?
it becomes smaller, "hydronephrosis"
What is the purpose of doing an ultrasound on a child with a UTI?
check anatomical features of the GU
What is urethral stenosis related to?

The risk of UTI's ________ with alteration of defense mechanisms.
increase

-repeated UTI's (are they colonized with this bacteria, or is this new?)

such as fatigue or anorexia
What should we suspect when there is blood-tinged urine?
kidney involvement
In a urinalysis, what is the most significant finding that would diagnose a UTI?
+ nitrites--they are a byproduct of E. coli
What does an elevated specific gravity (>1.025) indicative of?
dehydration
What does a decreased specific gravity (<1.001) indicative of?
dilute (did you fluid resuscitate? well hydrated?)
What is the normal specific gravity in a UA?
1.001 to 1.025
What is the normal amount of proteins in a UA?
< 20mg/dL

conclude?
UTI
Why are nitrites not always seen on a UA in an infant?
because they are urinating so much
If you do a clean catch UA, what amount of WBC's would be indicative of a UTI?
at least >50 WBC's
What types of diagnostic studies are done to monitor the GU system?
-ultrasound
-urinalysis
-urine C&S
-BUN/Creatinine
-voiding cystourethrogram (VCUG/VCG)
If you have a patient who is <2 years old with a febrile UTI, what must be done per guidelines?
ultrasound; make sure anatomy is normal
What is the care of a UTI?
-ultrasound (if first febrile UTI)
-sent home with prophylaxis: low dose Bactrim
-set up appointment for a voiding cystourethrogram
What is a voiding cystourethrogram?
-fill child's bladder with dye
-monitor for retrograde flow of bladder dye into the ureters
-reflux is graded
Is Bactrim prophylaxis a good idea in children?
a meta-analysis revealed decreased septic UTI's, but no change in renal scarring
What is the problem with patients on prophylaxis Bactrim?
patient might present with an illness, but the UA doesn't show infection (must wait 24 hr for urine
culture)
