[|Human|] I am 44 year old female.  Had gall bladder removed 1 month ago.  Lots of sludge and stones in gb and bile ducts.  Since surgery I have noticed that I am passi png White powder with urine.  No other symptoms other than tiredness.  Do you know what this may be?  Is it related to stones?
[|AI|]  Dear Madam had gall bladder surgery one month back, I would be interested to know if you had any catheterization for urination at that time (although unusual in laparoscopic surgery these days)? White powder in urine may be due to urine infection, casts or may be renal stone. You should under urine routine examination, urine culture and X-ray PUB to undergo evaluation for urine complaints. Gb stones and cholecystectomy has no connection with white powder in urine. Regards Chat Doctor.
