Abstract:
Objective To summarize and analyze the pathological data of 431 cases of renal biopsy from Quzhou, Zhe-jiang and to discuss the epidemiological characters via pathological distribution in Quzhou. Methods A total of 431 patients with kidney diseases hospitalized between January 2012 and December 2014 by our hospital were reviewed and their epidemiological characters and distribution of pathological patterns were analyzed. Results Among the 431 speci-mens, 181 cases were from males (42.0%), and 250 were females (58.0%, male/female=1:1.38). As to the clinical types of disease, the most common disease was nephrotic syndrome (NS, 178 cases, 41.3%), followed by chronic glomeru-lonephritis (CGN, 142 cases, 32.9%). As to the etiologic classification, a majority of 342 cases were primary glomeru-lonephritis (PGN, 79.3%), 77 cases were secondary glomerulonephritis (SGN, 17.9%), 11 cases were tubulo-interstitial disease(TID, 2.6%), and 1 case was renal transplantation disease(0.2%). Among the PGN patients, IgA nephropathy (IgAN) and membranous nephropathy(MN) were most commonly observed, accounting for 32.7%and 24.5%, respectively. Of the SGN patients, lupus nephritis(LN) was most common, accounting for 40.2%, which was followed by Henoch-Schonlein purpura nephritis (HSPGN, 18.2%) and hepatitis b virus-associated glomerulonephritis (HBVGN, 13.0%). Conclusion PGN is the most common etiological factor of kidney biopsy, with IgAN and MN at most. LN is the main type of SGN, followed by HSPGN and HBVGN. In Quzhou, Zhejiang, the incidence rate is higher in young adults, indi-cating that special attention should be paid on IgAN, MN and LN in prevention and treatment of kidney diseases.
