Hello and welcome to HCM. Thank you for your query. From your urine analysis it clearly indicates the presence of a urine tract infection (UTI), but I am sure you have been informed about this as your query is about UTI s. Now coming to your query, the cause for UTI s are many, but let me list some of the most common ones for you relating to your age and sex. They are: -As females have genitalis that is more exposed, this makes them more vulnerable to UTI s than men -Sexual intercourse is another common cause -Use of urinary catheters -Diabetes -Kidney stones -Kidney disorders -Spermicide use -Long duration s of being seated -Travel and many more. I would suggest you visit your doctor who will initiate a course of antibiotics (in case of bacterial source) and anti-fungals (fungal source), pain management medication (if pain is present) and a potassium chloride based solution (alkalizer syrup) which will help in relieving symptoms of UTI. You could also request for a urine culture examination, which will provide information on the infection-causing organism, this in turn helps in selecting the most suitable mode of treatment. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
