Importance of renal biopsy in patients aged 60 years and older: Experience from a tertiary care hospital.

This study outlines the importance of renal biopsy in elderly and describes the clinical and pathologic spectrum of renal diseases in patient ≥60 years. All patients (age ≥60 years) undergoing renal biopsies from January 2011 to December 2014 were included in this retrospective study. The clinical presentation and biochemical findings were recorded, and the patients were grouped based on their clinical presentation. Renal biopsies were also evaluated. The mean age of patients was 67.7 ± 6.4 years with a male:female ratio of 3:1. The most common clinical manifestation was nephrotic syndrome (37.4%) followed by rapidly progressive renal failure (RPRF) (20.6%). Amyloidosis and membranous nephropathy were two most common diagnoses in patients with nephrotic presentation whereas pauci-immune crescentic glomerulonephritis and cast nephropathy were common in patients presenting with RPRF. Clinical diagnosis differed from the histopathological diagnosis in 32% cases of nephrotic syndrome. There was good agreement between clinical diagnosis and histology in cases with RPRF. In 73% cases of elderly with (Type II) diabetes suspected of having nondiabetic renal disease clinically, renal biopsy showed evidence of diabetic nephropathy. Renal biopsy is essential in the diagnosis of renal diseases even in elderly. Amyloidosis and membranous nephropathy are common causes of nephrotic syndrome in elderly. Renal biopsy is very useful in diagnosing cast nephropathy and amyloidosis as they a...
