Conversation: The conversation between human and AI assistant.
[|Human|] When I urinated a small dark-colored something came out with the urine. This has happened several times. I fished the last one out and looked at it under a magnifying glass and found it to be fibrous. Its not a kidney stone. Any idea what it is?I have had a history of kidney stones and recently very frequent unination at night, sometimes as often as five or six times. I am 51 years old.
[|AI|]  Dear Patient, your clinical history and symptoms (dark purines, frequent urination, history) are very suggestive for an ongoing UTI or a parent stone in upper urinary tract. Moreover, often stones are expression of Otis, which may be coexisting. Thus, in your case, I would recommend urine culture, urinalysis, a renal US and three urine pap tests taken every 24h. In this way, you will get your urinary tract investigated. Let me know the results for further considerations, take care,
