I have been having tiny black or brown particles in urine for about 3 weeks now. I have no pain urinating except every so often I have to urinate frequently. What could this be?

These particles can parts of kidney stone & blood clots

Bacterial infection can also be associated with it.

Please get your urine tested.

I have been increasing my water intake the last few days and am seeing hardly any particles anymore. My doctor did a dipstick and a urinalysis. Everything was within normal parameters except I had a higher SG of 1.025. The only change was my doctor had me switch from a newer BP drug (Fosinopril with sodium with a diuretic) back to my old BP med (Fosinopril 20 mg) due to excessive urinization. What could be causing these particles and will they go away completel? Do I need to see a nephrologist or a urinologist?
