Hello Thanks for query. You have doubt that you have Kidney Failure. Creatinine level of 1 itself indicates that your kidneys are functioning normal and nothing to be worried about it. As regards increased frequency of urination this is common after the menopause and is due to what is called as Urehtral Senosis.(Narrowing of Urethral Passage ) The most probable cause of UTI may be due to Post Menopausal Urethral Stenosis which is very common in females after menopause. After the age of menopause there is generalized atrophy of all Genito Urinary Organs which also involves urethral passage causing narrowing of the urethral passage (Urethral Stenosis).Because of the urethral Stenosis there is incomplete emptying of the bladder during urination and some amount of urine always remains in the bladder what is called as residual urine .This stagnated residual urine is a source of infection causing UTI. I would suggest you to consult qualified Urologist for clinical assessment and get endoscopic examination of bladder (Cystoscopy) and Urethral Calibration done .This will to dilate your urethral passage and help in complete emptying of bladder and there by prevent getting UTI repeatedly.
