Hi... My grandfather is of age 86 lives in Kolkata. He has kidney problem where the kidneys are working partially. Creatinine level is 6.5, apart from that he is a heart patient and also has diabetes which are normal(controlled). Apart from dialysis, is there any medication by which he can urinate normally?, As he is of 86 years old, dialysis would be difficult for him. Is there any chance to improve kidneys working condition using only medication? (Someone might be specialist who can help us)  Please suggest me... Thank you.
