Thanq for ur question, But u have not mentioned ABT clear signs and symptoms and since wen ur father is having this problem.... And not told regarding on what allopathic medicines he is..!? Wether he has swelling in lower limbs,? Putting edema?? Less urine flow?? Ect assemet is needed... As his creatin level is high as much it suggest that kidney is failing to excrete the products sufficiently..and serum creatinine level in blood suggest kidney failure chances as high.. becz healthy kidney will excrete creatine.. The difference of creatinine in blood and urine will make sure how actually kidney is working.. Depend on that kidney transplantation choice can be opted... Hope it's helpful for u.. With regards...
