Patients were stratified into four 5\u2010year periods (2005\u20132009, 2010\u20132014, 2015\u20132019, and 2020\u20132024) based on biopsy date.

The mean age was 67.9\u2009\u00b1\u20095.7\u2009years, with a male\u2010to\u2010female ratio of 1.4:1. The proportion of elderly patients undergoing renal biopsy increased significantly across the four periods (19.1%, 22.5%, 33.9%, 38.9%;\n                      <jats:italic>\u03c7<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200960.160,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01). Nephrotic syndrome (NS) was the most common indication for biopsy, although its proportion declined over time. In contrast, the proportion of biopsies performed for chronic kidney disease (CKD) increased substantially. Primary glomerular nephropathy (PGN), secondary glomerular nephropathy (SGN), and tubulointerstitial nephropathy (TIN) accounted for 54%, 39.9%, and 6.1% of all cases, respectively. The most prevalent cause of PGN was membranous nephropathy (MN), and the leading pathological types of SGN included diabetic nephropathy (DN), antineutrophil cytoplasmic antibody\u2010associated vasculitis (AAV), and hypertensive nephropathy (HTN). Throughout the study period, the proportion of PGN decreased significantly (64.6%, 64.9%, 54.1%, 42.6%;\n                      <jats:italic>\u03c7<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200918.5,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), driven by a decline in MN (34.1%, 39.6%, 32.6%, 23%;\n                      <jats:italic>\u03c7<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200910.015,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.018).
