A Change in Diagnosis of Abdominal Pain.

A 17-year-old female was admitted to the hospital with symptoms of right-sided abdominal and flank pain, slight dysuria, and tactile temperature. Her presumptive diagnosis was pyelonephritis. She weighed 73.5 kg and had had a previous normal pregnancy. Pathology revealed multiple yellow calculi with thickened wall of the gallbladder, consistent with chronic pyelonephritis. She continued to have intermittent symptoms and underwent laparoscopic cholecystectomy 2 months after admission.
