Nephrosis



  1. General information
    1. Autoimmune process leading to structural alteration of glomerular membrane that results in increased permeability to plasma proteins, particularly albumin
    2. Course of the disease consists of exacerbations and remissions over a period of months to years
    3. Commonly affects preschoolers, boys more often than girls
    4. Pathophysiology
      1. Plasma proteins enter the renal tubule and are excreted in the urine, causing proteinuria.
      2. Protein shift causes altered oncotic pressure and lowered plasma volume.
      3. Hypovolemia triggers release of renin and angiotensin, which stimulates increased secretion of aldosterone; aldosterone increases reabsorption of water and sodium in distal tubule.
      4. Lowered blood pressure also stimulates release of ADH, further increasing reabsorption of water; together with a general shift of plasma into interstitial spaces, results in edema.
    5. Prognosis is good unless edema does not respond to steroids.
  2. Medical management
    1. Drug therapy
      1. Corticosteroids to resolve edema
      2. Antibiotics for bacterial infections

      4. Ankle edema
    3. Anorexia, vomiting, and diarrhea, malnutrition
    4. Pallor, lethargy
    5. Hepatomegaly
  4. Nursing interventions
    1. Provide bed rest.
      1. Conserve energy.
      2. Find activities for quiet play.
    2. Provide high-protein, low-sodium diet during edema phase only.
    3. Maintain skin integrity.
      1. Do not use Band-Aids.
      2. Avoid IM injections (medication is not absorbed into edematous tissue).
      3. Turn frequently.
    4. Obtain morning urine for protein studies.

Nephrosis (Nephrotic Syndrome)

  1. General information
    1. Autoimmune process leading to structural alteration of glomerular membrane that results in increased permeability to plasma proteins, particularly albumin
    2. Course of the disease consists of exacerbations and remissions over a period of months to years
    3. Commonly affects preschoolers, boys more often than girls
    4. Pathophysiology
      1. Plasma proteins enter the renal tubule and are excreted in the urine, causing proteinuria.
      2. Protein shift causes altered oncotic pressure and lowered plasma volume.
      3. Hypovolemia triggers release of renin and angiotensin, which stimulates increased secretion of aldosterone; aldosterone increases reabsorption of water and sodium in distal tubule.
      4. Lowered blood pressure also stimulates release of ADH, further increasing reabsorption of water; together with a general shift of plasma into interstitial spaces, results in edema.
    5. Prognosis is good unless edema does not respond to steroids.
  2. Medical management
    1. Drug therapy
      1. Corticosteroids to resolve edema
      2. Antibiotics for bacterial infections
      3. Thiazide diuretics in edematous stage
    2. Bed rest
    3. Diet modification: high protein, low sodium
  3. Assessment findings
    1. Proteinuria, hypoproteinemia, hyperlipidemia
    2. Dependent body edema
      1. Puffiness around eyes in morning
      2. Ascites
      3. Scrotal edema
      4. Ankle edema
    3. Anorexia, vomiting, and diarrhea, malnutrition
    4. Pallor, lethargy
    5. Hepatomegaly
  4. Nursing interventions
    1. Provide bed rest.
      1. Conserve energy.
      2. Find activities for quiet play.
    2. Provide high-protein, low-sodium diet during edema phase only.
    3. Maintain skin integrity.
      1. Do not use Band-Aids.
      2. Avoid IM injections (medication is not absorbed into edematous tissue).
      3. Turn frequently.
    4. Obtain morning urine for protein studies.
    5. Provide scrotal support.
    6. Monitor I&O, vital signs and weigh daily.
    7. Administer steroids to suppress autoimmune response as ordered.
    8. Protect from known sources of infection.

Enuresis

  1. General information
    1. Involuntary passage of urine after the age of control is expected (about 4 years)
    2. Types
      1. Primary: in children who have never achieved control
      2. Secondary: in children who have developed complete control and lose it
    3. May occur at any time of day but is most frequent at night
    4. More common in boys
    5. No organic cause can be identified; familial tendency
    6. Etiologic possibilities
      1. Sleep disturbances
      2. Delayed neurologic development
      3. Immature development of bladder leading to decreased capacity
      4. Psychologic problems
  2. Medical management
    1. Bladder retention exercises
    2. Behavior modification, e.g., bed alarm devices
    3. Drug therapy: results are temporary; side effects may be unpleasant or even dangerous
      1. Tricyclic antidepressants: imipramine HCI (Tofranil)
      2. Anticholinergics
  3. Assessment findings
    1. Physical exam normal
    2. History of repeated involuntary urination
  4. Nursing interventions
    1. Provide information/counseling to family as needed.
      1. Confirm that this is not conscious behavior and that child is not purposely misbehaving.
      2. Assure parents that they are not responsible and that this is a relatively common problem.
    2. Involve child in care; give praise and support with small accomplishments.
      1. Age 5-6 years; can strip bed of wet sheets.
      2. Age 10-12 years: can do laundry and change bed.
    3. Avoid scolding and belittling child.

Hypospadias

  1. General information
    1. Urethral opening located anywhere along the ventral surface of penis
    2. Chordee (ventral curvature of the penis) often associated, causing constriction
    3. In extreme cases, child's sex may be uncertain
  2. Medical management
    1. Minimal defects need no intervention
    2. Neonatal circumcision delayed, tissue may be needed for corrective repair
    3. Surgery performed at age 3-9 months; 2 years of age for complex repairs.
  3. Assessment findings
    1. Urinary meatus misplaced
    2. Inability to make straight stream of urine
  4. Nursing interventions
    1. Diaper normally.
    2. Provide support for parents.
    3. Provide support for child at time of surgery.
    4. Post-operatively check pressure dressing, monitor catheter drainage, assess pain.

Undescended Testicles (Cryptorchidism)

  1. General information
    1. Unilateral or bilateral absence of testes in scrotal sac
    2. Testes normally descend at 8 months of gestation, will therefore be absent in premature infants
    3. Incidence increased in children having genetically transmitted diseases
    4. Unilateral cryptorchidism most common
    5. 75% will descend spontaneously by age 1 year
  2. Medical management
    1. Whether or not to treat is still controversial; if testes remain in abdomen, damage to the testes (sterility) is possible because of increased body temperature.
    2. If not descended by age 8 or 9, chorionic gonadotropin can be given.
    3. Orchipexy: surgical procedure to retrieve and secure testes placement; performed between ages 1-3 years.
  3. Assessment findings: unable to palpate testes in scrotal sac (when palpating testes be careful not to elicit cremasteric reflex, which pulls testes higher in pelvic cavity)
  4. Nursing interventions
    1. Advise parents of absence of testes and provide information about treatment options.
    2. Support parents if surgery is to be performed.
    3. Post-op, avoid disturbing the tension mechanism (will be in place for about 1 week).
    4. Avoid contamination of incision

Exstrophy of the Bladder

  1. General information
    1. Congenital malformation in which nonfusion of abdominal and anterior walls of the bladder during embryologic development causes anterior surface of bladder to lie open on abdominal wall
    2. Varying degrees of defect
  2. Assessment findings
    1. Associated structural changes
      1. Prolapsed rectum
      2. Inguinal hernia
      3. Widely split symphysis
      4. Rotated hips
    2. Associated anomalies
      1. Epispadias
      2. Cleft scrotum or clitoris
      3. Undescended testicles
      4. Chordee (downward deflection of the penis)
  3. Medical management: two-stage reconstructive surgery, possibly with urinary diversion; usually delayed until age 3-6 months
  4. Nursing interventions: preoperative
    1. Provide bladder care; prevent infection.
      1. Keep area as clean as possible; urine on skin will cause irritation and ulceration.
      2. Change diaper frequently; keep diaper loose fitting.
      3. Wash with mild soap and water.
      4. Cover exposed bladder with Vaseline gauze.
  5. Nursing interventions: postoperative
    1. Design play activities to foster toddler's need for autonomy (e.g., Play-Doh, talking toys, books); child will be immobilized for extended period of time.
    2. Prevent trauma; as child gets older and more mobile, trauma more likely; teach parents to avoid areas such as sandboxes.

Vesicoureteral Reflux

  1. General information
    1. Regurgitation of urine from the bladder into the ureters due to faulty valve mechanism at the vesicoureteral junction
    2. Predisposes child to
      1. UTIs from urine stasis
      2. Pyelonephritis from chronic UTIs
      3. Hydronephrosis from increased pressure on renal pelvis
  2. Assessment findings: same as for urinary tract infections
  3. Nursing interventions for surgical reimplantation of ureters
    1. Assist with preoperative studies as needed (IVP, voiding cystourethrogram, cystoscopy).
    2. Provide postoperative care.
      1. Monitor drains; may have one from bladder and one from each ureter (ureteral stents).
      2. Check output from all drains (expect bloody drainage initially) and record carefully.
      3. Observe drainage from abdominal dressing; note color, amount, frequency.
      4. Administer medication for bladder spasms as ordered.
