Renal Pediatrics Flashcards
Gross hematuria DDx
Kidney stones Trauma AV malformation Renal vein thrombosis Acute tubular necrosis IgA nephropathy Alport nephritis Glomerular nephritis
Acute post strep GN
Decreased C3
Renal vein thrombosis
Neonates
Abdominal mass

Cyclosporine
Oncologic drugs
Heavy metals
IgA nephropathy
Most common hematuria
Normal C3
Alport nephritis
Eye and ears too

hemoglobinuria or myoglobinuria
No RBC casts
Non-glomerular
Systemic Glomerular with low C3
