My friend was hospitalized last week with high blood pressure and grade 4 hypertension retinopathy. Later after all tests doctor told it's stage 5 chronic kidney disease and his serum creatinine is 5.6. He never got any symptoms and no family history too about this. Is it curable ? Can transplantation gives 100% cure to this ? He is just 24years old. Please suggest what have to be done and how to overcome​ it.
