<s>[INST] Hi, I am Chitrendra Gaur. My father is 67 years old and have one kidney and one stunt also in Heart. The mentioned surgeries was done 7 years ago. Now he has been examined and tested for Kidney disease where he found Blood Urea 43, and Albumin in Urine +++.Kindly suggest how to get rid of these.Regards [/INST] According to the history your father is suffering from chronic kidney disease. But you didn't give me the history whether he has single kidney since birth or removed later due to infection. Whatever may be the reason, he is having protein leakage in urine. If the existing kidney size is normal, he needs renal biopsy if necessary. Consult good nephrologist nearby. All the best. If you have any questions feel free to consult me </s>
