Nephritis includes acute glomerulonephritis, acute glomerulonephritis and chronic glomerulonephritis, each with different chances of developing uremia. Acute glomerulonephritis has a very small chance of developing into uremia, at most 5%, and the majority of patients have a very good prognosis and are basically able to recover. In acute glomerulonephritis, the disease progresses more rapidly and is more dangerous, with about 1/3 of patients developing chronic renal failure and eventually uremia. Chronic glomerulonephritis is a more moderate disease, but the prognosis is the worst, as long as the disease is not cured, 100% of patients will definitely develop uremia. The main purpose of interventional therapy is to slow down the progression of kidney function and enter the uremic phase as late as possible, so that the quality of survival of patients will be greatly improved.
