Nefropatia na infância: estudo morfológico / Nefropathy in childhood: a morphological study

RESUMO

O presente trabalho analisou 992 biópsias de pacientes menores de 16 anos de idade no período de 1980 a 1994. As biópsias de pacientes do sexo feminino representaram 47,08% do total. As indicações clínicas para a biópsia mais frequentemente encontradas foram síndrome nefrótica, síndrome nefrítica e hematúria isolada. As glomerulopatias proliferativas representaram o diagnóstico anatomopatológico mais comum. O diagnóstico morfológico mais freqüentemente associado com a síndrome nefrótica foi a glomeruloesclerose focal e segmentar e aquele mais relacionado à hematúria isolada foi a glomerulopatia proliferativa por IgA.

ABSTRACT

In the present paper 992 renal biopsies of patients under 16 years of age were analysed in the period of 1980 though 1994. Biopsies of female patients accounted for 47,08% of all biopsies. The most freguent clinical conditions that prompted the biop- sies were nephrotic syndrome, hematuria as a sole symptom and nephritic syndrome. The proliferative glomerulopathies were found to be the most common pathologycal diagnosis. The mor- hological diagnosis most freguently associated with nephrotic syndrome was focal and segmental glomerulosclerosis and the one most often related to hematuria as a sole symptom was IgA proliferative glomerulosclerosis.
