The clinical and histopathologic findings in 225 Irish adults with nephrotic syndrome were reviewed. Membranous nephropathy was the most common lesion found (28%), followed by proliferative glomerulonephritis (17%), and focal sclerosing glomerulonephritis (16%). Minimal change disease was the least frequent cause for idiopathic nephrotic syndrome (12%). The major secondary cause of nephrotic syndrome was amyloidosis (13%). The patients were analysed for the predictive value of the level of renal function, presence or absence of hypertension, and the degree of proteinuria. It was not possible to determine the nature of the underlying lesion giving rise to the nephrotic syndrome using any of these variables. There was also no significant difference between primary and secondary glomerular disease with regard to these factors. It is concluded that renal biopsy remains the only definitive method of establishing the underlying lesion causing idiopathic nephrotic syndrome.
