The number of years that nephritis can keep is related to the pathological type of nephritis, concomitant symptoms and complications. In the case of microscopic lesion type or mild thylakoid nephritis, the prognosis is generally better, with slower progression of lesions and later onset of renal failure. The prognosis is poorer in the case of membranous capillary nephritis, focal segmental glomerulosclerosis and severe membranoproliferative nephritis, in which treatment is often ineffective and the disease progresses more rapidly, leading to chronic renal failure, which usually lasts about 5 to 10 years. If accompanied by significant hyperlipidemia, glomerular hypercoagulable state, the prognosis is even worse. Nephritis should also prevent recurrent infections as well as venous thrombosis, so as not to affect the prognosis, so in the treatment of patients should actively prevent complications.
