<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 35 year female, healthy. the past 3 years Ive been getting string like white substances every time I urinate. It is not painful. Ive gotten a bladder infection every 6 months for the past 3 years. What could be the cause? How do I get rid of the white substance in my urine?  <response>: Hi, welcome to Chat Doctor forum. Since you are healthy, and this issue is there for 3 years, it is unlikely to have a serious underlying causeI guess you have no hypertensionedema on legsred colored urineincrease or decreased urine output.Anyhow, you can do a urine routine examination. Depending on the result, you may need some blood tests like complete blood countrenal function test. The first thing to be sure before going for these investigations is that, the substances are not coming from your vagina, and get mixed up with urine. I hope you will find this information useful. Thank you.
