Ch. 24 Flashcards
cryptorchidism
- 1 or 2 testicles without descent by age 6 months
- Testes that are not palpable or not easily guided into the scrotum
- Managed by observation as testes may descend within the first year
- surgical repair if testes do not descend (recommended around 1 yr old by AAP)
enuresis
uncontrolled bed wetting
- higher incidence in B>G
- usually ceases btwn 6-8 years
- primary vs secondary
epispadias
- Less frequent than hypospadias; EXTREMELY RARE!!
- Dorsal (top) surface urethral opening (if seen in females opening is between clitoris and labia or on abdomen)
- Congenital
- Surgical repair is required….no circumcision
hypospadias
- Urethral opening is located below the glans penis or anywhere along the underside of the penile shaft (ventral opening)
- congenital
- hereditary
- 1/300 births
- Requires surgical correction around 6-12 months old (normal adult sexual functioning)…no circumcision
- Nursing assessment of every male newborn
hydrocele
- Presence of peritoneal fluid in the scrotal area
- May be indicative of an inguinal hernia
- Common in newborns but may not resolve until the end of infancy
- May prevent teste from descending
- Resolves spontaneously
- Surgical repair if continues into toddlerhood
neurogenic bladder
lack of bladder control due to nerve, spinal, brain injury
- MS
- spinal cord injury
- CP
catheter to empty bladder
oliguria v anuria
decreased urine output
v
no urine output
phimosis
the inability to retract the foreskin from the glans on the penis
- okay in newborn phase
- should retract by 3 years old
- may require circumcision to correct
paraphimosis
when foreskin is trapped behind the corona of the glans penis
pyelonephritis
inflammation of upper urinary tract and may involve kidneys
pyeloplasty
surgery performed when the tube that drains urine from the kidneys to the bladder is blocked
- if not corrected causes loss of kidney function, infections, and pain
renal insufficiency
poor function of the kidneys
- may be due to reduction in blood flow to the kidneys (renal artery disease)
vesicoureteral reflux (VUR)
- backwards ureteral flow of urine
- can be uni or bilateral
- normally affects the ureterovesical junction
GU physical exam: inspection
- general appearance
- physical growth (wt, ht, or length, Tanner staging)
- skin assessment
- LOC
- external genitalia
- abdomen: distention/mass
what are you “inspecting” when looking at the external genitalia?
- diaper rash
- placement of urethral opening
- discharge
- urine dribbling
- swelling
- bruising
GU physical exam: percussion and palpation
- distention/masses
- CVA tenderness (push on flank- assess for pain, if yes could be kidney infection)
GU physical exam: auscultation
- heart sounds
- HR- tachycardia?
- BP (machine <3, manual >3)
- lung sounds if child seems “puffy” (think pulmonary edema)
- bowel sounds
a + murmur is seen in children with what disorders?
- anemia
- renal disease
HTN is a sign of what GU disease?
renal disease
hypoactive or absent bowel sounds could mean what?
peritonitis
urine output: infants
9-10x/day
urine output: preschoolers
4-8x/day
*need reminders
expected urine output is calculated with what formula?
UO = 1ml/kg/hr
*newborns will produce 1-2ml/kg/hr; after 1 month, 1ml/kg/hr
1 gram of wet diaper = ___ mL of urine
1mL of urine
when is bladder capacity close to that of an adults?
12 years
normal urine characteristics: urine specific gravity
USG: 1.005-1.020
in-hospital hydration status; normal intake status
normal urine characteristics: appearance
clear, pale, yellow/gold
should be transparent straw color with minimal odor
normal urine characteristics: pH
avg. 6 (5-8)
- want the urine to be closer to 5 (more acidic to prevent infection)
acid base balance
abnormal urine lab characteristics
presence of:
- protein
- glucose (diabetes)
- ketones
- leukocyte esterase
- nitrites
- WBCs (< 1-2 is normal- irritation)
- RBCs (< 1-2 is normal- irritation)
- Bacteria
- Casts
pediatric issues related to GU
- can be difficult to examine (restraint)
- urine collection is complicated by age and determination of child
- conflict is created btwn parental teaching r/t exposed “private parts” and the need to perform exams, lab specimen collection, and nursing interventions
DDAVP (desmo-pressin)
action: antidiuretic hormone effect; causes renal tubule to increase H2O absorption leading to decreased volume of urine
indication: nighttime enuresis
nursing implications with DDAVP (desmo-pressin)
- nasal spray may cause irritation, nausea, flushing, or headache
- administer at bedtime alternating nostrils
- PO is preferred at bedtime
Lasix
action: inhibits reabsorption of sodium/chloride; leads to increased excretion of H2O and lytes
indication: nephrotic syndrome
nursing implications with Lasix
- give with food/milk
- monitor BP, renal function, lytes (esp. K+)
Albumin (IV)
action: results in fluid shift from interstitial to intravascular space
indication: nephrotic syndrome
nursing implications with Albumin (IV)
- use filter on IV tubing
- rapid infusion can cause vascular overload
- monitor VS
- observe for cardiac failure and pulmonary edema
antibiotics for a UTI are
not always appropriate for use in children
- some are, some aren’t
corticosteroids
indication: nephrotic syndrome
action: induces remission and promotes diuresis
ie. prednisone
what % of children respond to prednisone within 2 weeks?
90%
after remission of proteinuria, how long is prednisone continued for?
another 6 weeks at lower doses
IVIG
medication used for nephrotic syndrome
renal diagnostic studies
- UA
- Urine C&S
- BUN
- uric acid
- creatinine
- KUB
- IVP
- VCG/VCUG
- renal scan
- cystogram
- retrograde pyelogram
- ultrasound
- CT scan
- MRI
- renal arteriogram
- renal biopsy
renal biopsy
removal of a small piece of the kidney to examine the tissue
ultrasound
can be used on abdominal area or back to get a picture/scan of kidneys, bladder, ureters
VCG/VCUG
- a voiding cystourethrogram uses a small amount of radiation to make images of a person’s urinary system
- these images help doctors see problems in parts of the urinary system: bladder, urethra, ureters
creatinine
elevated in renal disease
infant: 2-5.5
child: 0.3-0.7
adolescent: 0.5-1
uric acid
elevated in renal disease
2-5.5
BUN
elevated in renal disease
newborn: 4-18
infant, child: 2-5.5
