Urology Flashcards
kick ASS
what are the provider’s 2 main jobs in relation to urology?
1) take care of the bladder to protect the kidneys
2) help assure social confidence
what are the bladder’s 2 main jobs?
1) store urine
2) empty urine
the shape of the bladder is like… ?
an inflated balloon
what works together to successfully store & empty urine & feces?
12-14 different reflex arcs
how do the bladders & bowel function–neurological control?
through a delicate interplay between the:
1) sympathetic nervous system
2) parasympathetic nervous system
(voluntary & involuntary neural control of both urine & feces)
what muscles control bladder/bowel function?
teamwork of many diff muscles, including:
- -detrusor
- -internal sphincter
- -external sphincter (pelvic floor or “bowl”)
what tests can determine if you are performing kegel exercises effectively?
biofeedback
what do kegel exercises do?
help you to control your internal & external sphincter
what is impt to include in a urology history?
- -voiding pattern: frequency, urgency, dysuria, retention, wetting damp or soaked)
- -> St. Vincent’s curtsey (pee-pee dance)
- -stool character & bowel pattern, “corn test”
- -drinking & voiding diary
- -hx of sexual activity or abuse
hallmark of a neurogenic bladder?
drips of urine coming out
what amount of time should be recorded in a drinking & voiding diary?
48 hrs worth is ideal
what should be included in a voiding diary?
- -color, odor, frequency, & volume of urine
- -ECA
what is ECA?
expected capacity for age:
age + 1 or 2 in ounces, for kids 2 and older
what does dark urine indicate?
not drinking enough
w/UTI, what do you treat first?
treat constipation 1st
w/spinal bifida occulta, what urinary problem can occur?
can have a neurogenic bladder
what should you pay attention to on physical exam that may point to urinary issues?
- -low-set ears
- -BP
- -growth
- -edema, pallor, dehydration
- -costovertebral tenderness
- -external genitalia abnormalities
- -sacrum (dimple?) or neurological abnormality
- -reflexes (v. impt!)
what 6 lab tests would you do w/a urinary issue?
1) UA (urinalysis), non-sterile
2) enhanced UA, Neubauer hemocytomer to obtain WBC/mm3 count from uncentrifuged urine
3) Urine culture & sensitivities, C&S
4) Serum BUN
5) Creatinine w/creatinine clearance
6) Serum electrolytes & acid base status
what is impt to remember for urine culture & sensitivities test? (c&s)
must be midstream clean catch or catheterized urine
what does serum BUN measure?
urea concentration in serum
what is the purpose of creatinine w/creatinine clearance test?
estimates glomerular filtration rate
what is serum electrolytes & acid base status test used for?
to check for renal tubular abnormalities
some docs check what for all kids on DDAVP?
Na balance
definition of nocturia
the complaint that the individual has to wake at night one or more times for voiding
DDAVP
Desmopressin
- -reduced urine production
- -used in tx of D.I., bedwetting, nocturia
how should boys prepare for urine specimen collection?
- -wipe meatus w/ 3 different wipes
- -> tip/center to shaft
- -then mid-stream
how should girls prepare for urine specimen collection?
- -wipe meatus w/ 3 different wipes
- -> front to back
- -then mid-stream
how can we avoid mixed flora culture results in girls?
have them take bath or shower before
w/urine specimen collection, what should we always order?
always order UA & C&S
if possible, what should you do before starting antibiotics?
wait for c&s results
what should creatinine levels be in infants?
it is normal for creatinine in infants to be low!
what is an enhanced urinalysis doing?
counting the # of white cells
constipated kids are at high risk for… ?
UTIs
if are holding back poop–are also holding back urine!
5 types of diagnostic tests we can do w/urinary dysfunction?
1) Ultrasonography
2) voiding cystourethrogram (VCUG)
3) IVP (intra venous pyelogram)
4) nuclear imaging scans
5) MRUogram
what does ultrasonography do?
non-invasive structural information
(look for: hydronephrosis, kidney size, scarring, cysts, healthy kidney parenchyma, thickened bladder wall, pre & post-void syndromes)
if high-grade ultrasound was done in utero, do we need to do ultrasonography later for urinary dysfunction?
not needed
what is the first line test for evaluation of renal system?
ultrasonography
what is the only way to diagnose or r/o reflux?
by doing a VCUG (voiding cystourethrogram)
a very difficult test
what does an IVP show?
the structure & function of renal systems
what is a benefit to doing nuclear imaging scans?
involves less radiation than IVP
what is the purpose of a MRUrogram?
studies anatomy & function without radiation
–done w/ and w/out contrast; long study, motion artifact
4 types of “minor” urinary dysfunctions?
1) extraordinary daytime urinary frequency syndrome
2) giggle incontinence
3) stress incontinence
4) post void dribbling
as PNPs, should we order an IVP?
never order this! let specialist do it
extraordinary daytime urinary frequency syndrome is characterized by:
- -voiding every 10-20 min.
- -no incontinence, no dysuria
extraordinary daytime urinary frequency syndrome affects what age group?
3-8 yrs old: generally young school-aged kids
often occurs @ stressful times: going to kindergarten, being bullied at school…
what do we do to treat extraordinary daytime urinary frequency syndrome?
–give time
(once they get rid of stress: goes away! us. self-limiting disease)
–flow/EMG may help teach child
what is giggle incontinence?
embarrassing wetting (not just leaking) assoc. w/giggling & laughter
tx’s for giggle incontinence?
- -anticholinergics
- -ritalin
- -biofeedback to strengthen outlet
- -kegels! (cheaper. to contract & expand pelvic floor)
stress incontinence
incontinence w/running, jumping, & high impact landing
–weakness in outlet
stress incontinence often occurs in:
athletes or obese patients
how can stress incontinence be treated?
- -void prior to activity
- -Biofeedback/kegels to strengthen outlet
post void dribbling
urine accumulation in lower vagina
–urine trickles out as she stands
post void dribbling mainly occurs in:
mostly in obese girls (v. common problem!)
what causes post void dribbling?
poor posture during micturition
may help to straddle toilet/sit backwards or lean forward to exaggerate bladder angle
