RESUMO
Abtract:Purpose To analyze epidemiological characteristics and pathological types of 1 645 renal biopsies in Jiangsu province. Methods The reports of 1 654 percutaneous renal biopsies performed from January 2009 to June 2013 were retrospectively analysed . Results 1 597 out of 1 645 renal patients were successfully biopsied with a success rate of 97. 1%. Primary glomerular diseases ac-counted for 78. 56% of the total patients, secondary glomerular diseases 18. 71%. IgA nephropathy and mesangial proliferative lession accounted for high percent of primary glomerular diseases. Lupus nephritis was the most frequent pathologic type of secondary glomeru-lar diseases, followed by allergic purpura nephritis and diabetic nephropathy. Mesangial proliferative glomerulonephritis and hyperten-sive renal injury were more common in the Southern than in the Northern Jiangsu province, while acute tubular necrosis and allergic purpura nephritis were less in the Southern Jiangsu province. Conclusions Primary glomerular disease is still the most frequent glo-merular diseases in Jiangsu province, among which the IgA nephropathy was predominated. In secondary glomerular disease, lupus ne-phritis is the most frequent pathological type. The incidences of kidney diseases have geographical variation.
