hi, my father had an operation for stone in his right kidney in 2003, in 2010 he suffered again the same problem but this time stone were found in his both kidneys, bladder. due to which his blood urea went above 80 and cretenine above 5. then he had an laser operation by 2010....... after that he had some problems in urine for few days. now there are no stones but his right kidney is slightly deformed and urea and creatnine are increased................... we have taken doctors prescriptions, but i want a healthy diet chart for him. he has blood sugar, blood preasure. he is 52 year old......
