There is indeed a urology forum on this site that I moderate as well.
Diarrhea is a side effect of gallbladder surgery. Sticking with a low-fat diet, as well as smaller portion size, can help abate the symptoms.
I am not aware of the excess bile salts/diarrhea being associated with uric acid stones. Those with the metabolic syndrome (i.e. high triglycerides and obesity) can have an increased incidence of bile acid stones.
I would discuss this question with your personal physician.
Followup with your personal physician is essential.
