GU Flashcards

1
Q

Variations in the pediatric GU system: infants

A

Tubules have less surface area = decreased water absorption
More prone to excess fluid volume and dehydration. Cannot concentrate urine very well
Immature renal system = inability to handle increased protein intake
Sodium excretion is lower = less able to adapt to Sodium loss or excess
UOP 1-2 ml/kg/hour

Q

Inguinal hernia

A

Occurs when abd tissue extends into the inguinal canal
Palpable non-tender mass proximal to the scrotum
One of the most common conditions in children
Surgery is required immediately if hernia becomes incarcerated
Otherwise surgery can wait and is usually done after 3 mos. of age

21
Q

What is vesicoureteral reflux (VUR)

A

The retrograde flow of urine from the bladder to the kidneys resulting in urine reflux into the renal pelvis causing causing hydronephrosis and kidney damage

22
Q

Types of VUR

A

Primary VUR: congential anomaly

Vomiting

24
Q

VUR treatment

A

Prophylactic antibiotics
Surgical resection of ureter
Prevention of UTI’s/pylonephritis
Bladder emptying education

Routine VCUG and cultures

25
Q

VUR diagnostics

A

Urinalysis
Urine culture
Renal/bladder ultrasound
VCUG

26
Q

UTI

A

Infection involving the kidneys, ureters, bladder or urethra
Escherichia coli is responsible for 90% of all UTI’s

27
Q

UTI diagnostics

A

UA (blood, nitrites, WBC, bacteria)
Culture w/ sensitivity

28
Q

Teach girls to wipe front to back
Keep hydrated
No bubble baths
Cotton underwear
Urinate before and after sex
No “holding it”

31
Q

Pathology of acute glomerulonephritis

A

Infection: post skin or pharynx infection with group A strep
Immune response: inflammation of glomeruli and obstruction from strep antibodies

Pathology of nephrotic sydrome

A

Initial cause unknown –>
Glomeruli become permeable to proteins –>
Massive proteinuria & hypoalbuminemia –>
Decreased osmotic pressure –>
Fluid shifts into interstitial fluid –>
Kidneys conserve Na and water –>
Massive edema –>
Liver increases lipid production –>
Hyperlipidemia

44
Q

What is primary enuresis

A

Most common
Child has never had a dry night
D/T maturational delay and small fx of bladder
Not associated with stress

45
Q

What is secondary enuresis

A

Child begins bedwetting after being relatively dry for 3-6 months
IS associated with stress and psychiatric issues
Also can be D/T infection or sleep disorders

46
Q

What is diurnal enuresis

A

Daytime incontienence
Usually d/t holding urine
Can be secondary to constipation, stress, UTI, and laughing

47
Q

What is nocturnal enuresis

A

Nighttime bedwetting
Typically subsides on it’s own by 6 years of age
Can be secondary to increase of fluid intake at night, sleep apnea, UTI, constipation, emotional stress, sexual abuse

48
Q

Management of diurnal enuresis

A

Rule out physical causes
Beh training:
Set voiding schedule
Increase fluids during day to increase frequency

49
Q

Management of nocturnal enuresis

A

Rule out physical causes
Limit fluid intake after dinner
