Depending on your age and risk factors- it is always a good idea to see a doctor and determine if a colonoscopy is indicated. ...Read more

Had a UTI last month went away. Urine culture today shows negative. Still have urgency and frequency for over a month and couple weeks will it go away?

Had a UTI last month went away. Urine culture today shows negative. Still have urgency and frequency for over a month and couple weeks will it go away?

Urgency & frequency: Let's clear up a common misunderstanding. Unless you're pregnant, there's no need to get a urine culture after finishing a course of antibiotics because we're not going to treat asymptomatic bacteriuria in adults, certainly, not in those who have an indwelling catheter. But you still have UTI symptoms despite negative urine culture so you need to get tested for sexually transmitted diseases. ...Read more

Can you still have urethritis if your urine cultures are coming back negative, after having a uti, that I got treated for and urine culture now (-).

Yes: Urethritis is inflammation of urethra. As such, it has several causes, most frequently urinary tract infection such as bladder or kidney infection. Sexually transmitted disease/infection are another common cause of urethritis. However, typical urine culture won't look for std/stis. You'll need separate testing for those bacteria & virus which cause std/stis. ...Read more

I feel burning in urine for since last 2 year. My urine culture report 3 times & GUTB culture is nagetive. I do sex frequently. Sometime urine is cloudy?

Missing the Point: The most common problem in men with these symptoms is not TB nor it is a bladder or prostate infection. It is Chlamydia and/or gonorrhea.

The leukocytes and nitrates do not represent an actual bacterial infection but other viral, chemical, or environmental reasons for a positive result 3.
