<prompt> The pathological feature in Wegeners granulomatosis on renal biopsy is:Nodular glomerulosclerosisFocal necrotizing glomerulonephritisGranulomas in the vascular wallGranuloma of parenchyma of kidney  <response>: Wegeners Granulomatosis : The renal lesions range from a mild early disease, where glomeruli show acute focal necrosis with thrombosis of isolated glomerular capillary loops focal and segmental necrotizing glomerulonephritis. Advanced glomerular lesions are characterized by diffuse necrosis and parietal cell proliferation to form crescents crescentic glomerulonephritis.
