<s>[INST] Hi doctor,My 66 year old father suddenly got a high fever and in few days we discovered he has a urinary tract infection. He is a diabetic and on insulin. He is a very disciplined person when it comes to his health. He checked his creatinine levels early this year and it was in the normal range. After admitting him to the hospital, his fever was gone and the doctor said he would go home in two days. His creatinine is increasing every day and has reached from 1 to 4 in three days. Same is the case with urea which is 125. The doctors are asking for a temporary dialysis to be started immediately, but we are not sure. Please help. [/INST] Hello. I am sorry to hear about your father. Hope this has helped alleviate your concerns. For further queries consult a nephrologist online --> </s>
