Glomerular alterations in idiopathic haematuria--ultrastructural and morphometric analysis.
Re-evaluation of kidney biopsies has been done along with morphometric analysis of glomerular basement membrane thickness (G.B.M.) in 41 cases of idiopathic haematuria, in whom the initial routine light, immunofluorescent and electron microscopic examination had not shown any significant alterations. Extreme attenuation of G.B.M. (mean thickness of 2581 +/- 488 A) had been found in thirty one patients in contrast to mean GBM thickness of 4295 +/- 470 A found in control group. Absence of any history of familial haematuria in these patients distinguished them from hereditary nephropathies and hence categorized under the term thin basement membrane nephropathy. Follow up of these patients for upto 8 years had shown persistence of symptoms without further deterioration of renal function as well as morphology.
