Peds Nephrology Flashcards
What criteria must be met to diagnose pediatric CKD?
GFR <60 for > 3 months
or
GFR >60 + evidence for structural damage (albuminuria, proteinuria, pathologic abnormalities on histology or imaging)
Most common cause of pediatric CKD?
Congenital diseases (60% of cases)
Name 5 congenital diseases that can cause pediatric CKD.
Obstructive uropathy Renal hypoplasia Renal dysplasia Reflux nephropathy PKD
What is the second most common cause of pediatric CKD?
glomerular disorders
Name 3 causes of glomerular disorders?
FSGS
Membranoproliferative glomerulonephritis
Minimal change disease
Presenting signs and symptoms of non-glomerular pediatric CKD?
Polyuria
Elevation in serum Cr
Poor growth
Presenting signs and symptoms of pediatric glomerular CKD?
Tea or cola colored urine (hematuria, RBC casts)
Edema
Elevation of serum Cr
Elevated BP for age
What imaging study would you order for suspected pediatric CKD?
Ultrasound
When managing pediatric CKD, you want to treat reversible kidney dysfunction. What are some reversible causes of kidney dysfunction?
Decreased perfusion to kidneys (hypotension, volume depletion, some medications) Nephrotoxic drugs (NSAIDs, contrast, aminoglycosides)
How do you slow progression of pediatric CKD?
Same as adults - ACEI/ARB for kids with HTN + proteinuria
Symptoms of pediatric CKD?
Anorexia, fatigue, N/V, pericarditis, bone and mineral disease, decreased neurocognitive function.
What are some examples of mineral bone disease that can occur secondary to pediatric CKD?
Growth failure, AVN, skeletal fractures/deformity/pain, vascular calcification
Treatment for mineral bone disease?
Diet, calcium binders, vitamin D2/D3, Vitamin D analogs
Renal replacement therapy should be considered at what GFR?
GFR <30
1st line renal replacement therapy?
Kidney transplantation
2nd and 3rd line renal replacement therapies?
2nd: Peritoneal dialysis
3rd: Hemodialysis
Examples of obstructive uropathy?
Stricture
Stones
Stenosis
Posterior ureteral valves
What is reflux nephropathy (vesicoureteral reflux)?
Retrograde passage of urine from the bladder to the upper urinary tract
What is renal dysplasia?
Malformed kidneys on a microscopic level
T/F? Kidneys with renal dysplasia are usually normal in size
False - usually smaller than normal
