hi. noted history of gallstones and prescription of ursocol. what your doctor did is what you call conservative management of your gallstones. and yes, nothing is wrong with that. are you experiencing any signs or symptoms (abdominal pain, nausea, vomiting, fever, jaundice, tea-colored urination) recently? and how frequent do these symptoms occur? if there are occurrence and/or progression of symptoms despite the decreasing size of stones in your ultrasound report, it is best if consult with a doctor, preferably a gastroenterologist or a general surgeon, for physical examination and clinical evaluation. other diagnostics such as liver function tests, blood count, bilirubins will be recommended as needed. management (medical and/or surgical if indications are found) will be directed accordingly. definitive management of gallstones is cholecystectomy or surgical removal of gallbladder. it may be done laparoscopically (goldstandard) or thru open technique. low fat low salt diet is also advised. hope this helps. good day!! ~dr.kaye
