I have a question about kidney function. I had a urinary tract infection about two years ago. From that period, I am doing blood tests to evaluate the kidney function every 15 days. My urine test is always within normal range, and no protein or glucose has been found. My blood creatinine and urea are also within the normal range. Creatinine goes from 70 to 88, and urea is always steady at 4 to 5. The eGFR last time was 130 using creatinine and cystatin from the blood. My question is, can kidney function degrade so fast? Do I need to check it so often? The doctor that suggested to do checks on a regular basis is not a specialist in urology. He just told me that kidney diseases do not show symptoms until it is too late. I am not diabetic, my blood pressure is normal, and no one in my family has any issues with kidneys. How often should I check my kidney function? Thank you very much.

Thanks for your answer. I do not think that I am suffering from any disease. I just had a urinary tract infection, and there was some increase of leukocytes in the urine, so the doctor said that it is a regular UTI. Everything else was fine, and that it is a good thing to check the kidney function, to be sure there was no damage. Even then my urea and creatinine were in the normal range. Maybe it was not kidney related. Is once a month good for a checkup? And can you tell me what other tests except for urea, creatinine, and regular urine check, should I do? After that UTI, I did a 24-hour urine check and creatinine clearance, and all were within normal range. My eGFR from that test was 160. So can kidney function degrade fast, and is it necessary to do monthly checks if all reports are within normal range?
