### input:
I have pain while urinating especially towards the end of urinating. Sometimes there s the feeling of urgency. Also, when I urinate, there is a whitish sediment that settles to the bottom when I urinate in a cup. The toilet water often looks cloudy. No blood in urine . I often urinate at the first feeling to prevent any infection. I ve had several urine lab test as well as culture. The culture is clear. I ve been on three different does of Cipro as well as three different doses of Diflucan . I am a Peritoneal Dialysis patient. I ve inquired with the Pharmacist whether difulcan gets dialysed out immediately. He checked his book and he said not really. I also drink 6-8 oz of Cranberry Juice and take 2 cranberry pills per day. I try to drink a lot of water -- no soda . This has been going on for about 6 months. I had a cystoscopy and he found no blockage or anything strange in my bladder. However, he excreted a lot of the sediment using saline solution. I would like your thoughts in the matter. Is there anything you know about the my Urologist hasn t tried yet?

### output:

I will start from the beginning. You have acid & are on CARD. Capd presumably is OK, although it would have been better had you mentioned details about that too. The symptom you are experiencing is Stranger & the cause for this & whitish substance appears to be Graveluria. Commonest cause of this condition is stone forming substances like oxalate, uric acid, phosphorus,calcium. This does not suggest infection therefore you may stop antibiotics. You may also stop cranberry tabs & reduce the quantity of cranberry juice to 150-200ml daily. Please mention all the details about your Chat Doctor.
