<s>[INST] My creatine level in February 2013 was o.53 with eEGFR Rate of 99. All other baseline tests were normal except for microscopic hematuria. I am 68 now with pseudomonas bacterial UTI that hasn t gone away even with ciprofloxasin. June 2014 creatine level was 0.9. Using same formula as used in 2013, the eEGFR rate is now 66!!! Same lab says Less than 60 indicates chronic renal disease. I know of NO risk factors (drugs, lifestyle, toxins, hospital care) that would make this happen. I look and feel very good.But the UTI isn t going away. Just saw my doctor, cystoscopy scheduled. He was not concerned.Any reason eEFGR could go down so fast??? (I am doing heavy contructioin work in my house.) [/INST] Hi, dairy have gone through your question. I can understand your concern. You should not worry about that.  You may have urinary tract infection. Repeated urinary tract infection may be due to diabetes.  You should check your blood sugar level. Heavy exercise can also cause this.  So don't worry about that.  Repeat your creatinine level and EFR level after a month. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
