title: Typical MPGN with few urinary abnormalities.
abstract: We describe the concurrent appearance of membranoproliferative glomerulonephritis (MPGN) in renal biopsy samples and normal urinary sediment without hematuria, proteinuria, or renal dysfunction in 1 child and asymptomatic microscopic hematuria without significant proteinuria or renal dysfunction in 2 children who were subsequently followed up for many years. The only other abnormality detected was hypocomplementemia. This is the first report of biopsy-proven typical MPGN in patients with few urinary abnormalities. A renal biopsy should be considered in children with hypocomplementemia, regardless of urinalysis findings, to exclude MPGN.
