title: Epidemiologic data of adult native biopsy-proven renal diseases in Croatia.
abstract: OBJECTIVE
  There is a paucity of epidemiological data on biopsy-proven renal disease in Croatia. The purpose of this report is a review of clinical and histological data, over a period of 15 years, from the single biggest adult native renal biopsy center in Croatia.
  
  
  METHODS
  This report includes data from 922 adult native renal biopsies in patients referred from the whole country and performed in our center from 1996 till February 2012. Data on age, gender, serum creatinine, urine sediment, 24-h proteinuria, clinical syndrome and histological diagnosis were collected and analyzed retrospectively. In all patients, light, immunofluorescence and electron microscopic analysis was performed.
  
  
  RESULTS
  The median age of the patients was 48 years (interquartile range 36-59 years), and the majority of patients were men (57.8 %). The most common indication for renal biopsy was nephrotic syndrome (40.3 %) followed by asymptomatic urinary abnormalities (31.7 %). The most common biopsy-proven renal disease in total was IgA glomerulonephritis (19.3 %), followed by focal segmental glomerulosclerosis (FSGS) (15.8 %) and membranous glomerulonephritis (9.2 %). In men, similar results were found, while in women, the most common were hereditary nephritis (13.4 %), FSGS (12.9 %) and connective tissue disease-related glomerular disorders (11.6 %).
  
  
  CONCLUSIONS
  The presented data are an important contribution to the better understanding of the epidemiology of biopsy-proven renal disease in Croatia and Europe throughout comparison with other registry data. This data should be the basis for the formation of Croatian Registry of Renal Biopsies.
