What could cause presents of white particles in my urine?

Two days ago, I have noticed some white particles in my urine. First, I wasn’t sure because I thought I didn’t see good, but after I urinate in a bottle, I become pretty sure that there are really some white bumps in my urine.
That surprised me a lot, because I didn’t had an opportunity to see anything like this before.
I was a little frightened because I didn’t know what could cause this. So I’m asking you. Can maybe a bacterial infection cause an appearance of such particles or some sexually transmitted disease?
If anyone had similar symptoms- please help!

You are right about one thing-that is a very uncommon situation but, I insure you that you don’t have any reasons to be worry.
First of all, these particles are in most cases caused by urinary infection but infection of an upper parts and that’s way you probably don’t have any urinary infection symptoms.
I suggest you to get some antibiotics and then check your urine for possible particles.
I must mention that cause of your particles can be urolithiasis. Urolithiasis is condition when stones block your urine passing and can cause ammoniac particles in urine.
So, visit your doctor and determine right cause of those particle and you will not what is the next step in order to cure your self.
