Pediatric - Genitourinary Flashcards
Pediatric Genitourinary System:
How does it differ from adults?
- Kidneys large in relation to abdomen until adolescence
- Urethra is shorter
- Female infants urethra opening in close physical proximity to rectum increases risk for infections
- GFR slower infant and young toddler – less able to concentrate urine and reabsorb amino
- acids increased risk for dehydration during times when fluid loss or decreased fluid intake
- Bladder capacity newborn 30mLs – adult capacity by 12mos of age 270mLs
- Average 1yo voids 400-500mLs /day vs Adolescent 800- 1400 mLs / day
- Infant or toddler voids 9-10 x/day vs by age 3 same as adult 3-8x/day
- Reproductive organs immature
Pediatric Genitourinary System Assessment:
Health History
- Pregnancy hx of mother: polyhydramnios,oligohydramnios, DM, HTN, ETOH or drug use
- Birth hx: single umbilical artery, abdominal mass, chromosome
- abnormality or congenital malformation
- Fhx: renal disease, chronic UTIs, renal calculi or parental enuresis
- HPI: when sxs started, assoc symptoms, progression of sxs,
- voiding patterns, age of TT, incontinent episodes
- Pmhx: spina bifida, myelomeningocele, past UTIs, surgeries
- Adolescent female: menarche, sexual behaviors
Pediatric Genitourinary Assessment,
cont. (HPI)
- dysuria, frequency, urgency, blood in urine, incontinence, changes in voiding pattern, Urine odor, discharge, edema, masses in groin, scrotum or abdomen, flank or abdominal pain, cramps, N/V, back pain, poor growth, wt gain, fever, trauma
Pediatric Genitourinary Assessment, cont. (Physical Assessment)
inspect: growth pattern, pruritis, edema (periorbital/general)
external genitalia rash, constant dribble of urine, displaced
urethral opening, discharge, labial fusion (females), scrotal sac
(male) edema, enlargement, discoloration
palpate: abdomen - masses, tenderness include CVA, scrotum -
bilateral testicles, masses, circumcised?
Pediatric Genitourinary Structural Disorders: Bladder Exstrophy
- congenital
- Bladder open (inside out) and exposed outside of the abdomen/rectus muscles separated
- Pelvis may be malformed
- Dx: prenatal US
- Tx: Surgical repair within days of birth
- occasionally urinary reservoir vs repair of bladder
Pediatric Genitourinary Structural Disorders, cont. - Bladder Exstrophy
(Nursing Assessment)
- Bright red bladder on outside of abdomen
- Draining urine
- Skin breakdown
- Malformed urethra
- Malformed penis (males)
Pediatric Genitourinary Structural Disorders, cont.
(Bladder Exstrophy) - Nursing Management
- Preventing Infection
- Preop: supine position, bladder kept moist, covered with sterile plastic bag, soiled diapers changed, sponge bathe
- Post op: urinary catheter/suprapubic catheter
*
- Post op: urinary catheter/suprapubic catheter
- Preventing Skin Breakdown
- Preop: protective barrier creams
- ostomy nurse consult
- positioning or bracing if pubic arch separated
- Maximizing Comfort:
- Post op: Meds for bladder spasms
- Risk for bleeding:
- Post op: urine bloody should clear within a few days
- If urinary reservoir:
- Post op: stoma catheterization 4x/day
- Educate parents
- mucus-like urine and cloudy
- HR for Latex allergy
- latex free catheters
- latex free gloves and other supplies
Pediatric Genitourinary Structural Defects, cont. -
Hypospadias
Urethral opening on undersurface (ventral surface) of penis
Pediatric Genitourinary Structural Defects, cont. - Epispadias
Urethral opening on dorsal surface of penis
Pediatric Genitourinary Structural Defects, cont.
- Hypospadias: Urethral opening on undersurface (ventral surface) of penis
- Epispadias: Urethral opening on dorsal surface of penis
- If left uncorrected, urine stream inaccurate from standing position, Erectile dysfunction and/or interfere with the deposition of sperm (infertile)
- Surgical correction: 6mos -12mos of age
- Defer circumcision till after repair
Pediatric Genitourinary Structural Defects, cont. - (Nursing Assessment Hypospadias/Epispadias)
*** Nursing Assessment Hypospadias/Epispadias:
report of unusual urine stream or observance
* Inspect placement of urethral meatus
* Inspect for chordee
* Inspect/palpate for testes
* Nursing Management Post op:
* Urinary drainage via tube or stent while site heals
* Tube taped with penis in upright position prevent stress on incision
* Antispasmodics
* Double diapering – inner contains stool, outer urine (see Nursing procedure 21.2)
Obstructive Uropathy - Pediatrics
(Hydronephrosis)
Pelvis and Calyces of kidney dilated increased fluid
Causes: congenital
result of obstruction
secondary to vesicoureteral reflux
Complications: renal insufficiency
HTN
renal failure
Obstructive Uropathy – Pediatrics
Nursing Assessment (Hydronephrosis)
- Health hx may include FTT, hematuria, presence of abdominal mass, sxs of UTI
- Physical exam BP, palpation may reveal enlarged kidneys or distended bladder
- Treatment: dependent on severity may be watch and wait, may need surgery to correct the cause ie blockage or correct reflux
Obstructive Uropathy – Pediatrics, cont.
(Vesicoureteral Reflux)
- Urine from the bladder flows back up into the ureters
- Reflux occurs during bladder contraction with voiding
- Uni- or bi- lateral
- Increased pressure placed on kidney can lead to renal scarring and HTN later in life
- Primary VUR: congenital
Secondary VUR: other structural or functional problems ie neurogenic bladder, bladder
dysfunction or bladder outlet obstrutction
Approx 30-50% children with UTI have VUR
Goal of Management:
Preventing pyelonephritis and subsequent renal scarring
Antibiotic prophylaxis
Good voiding habits and hygiene practices
Surgery if Grade 3-5
Pediatric Genitourinary Disorders, cont.
(Urinary Tract Infection)
- Most commonly affects the bladder
- Common organism: E. coli
- Others: Klebsiella, S. aureus, Proteus, Pseudomonas,
- Haemophilus
- Bacteria enters in an ascending manner
- Contributing Factors: urinary stasis, not completely emptying bladder with voids, decreased fluid intake, sexually active female teen
- If untreated may lead to pyelonephritis
- Presentation UTI:
- Infants: fever, irritability, vomiting, FTT or jaundice
- Children: fever, vomiting, dysuria, frequency, hesitancy, urgency and/or pain
- Diagnostics UTI: UA and cx
