EurekAlert -- Morbidly obese patients who undergo a particular type of gastric bypass surgery called Roux-en-Y gastric bypass (RYGB) are at an increased risk of developing kidney stones – small, pebble-like deposits that can result in severe pain and require an operation to remove them – earlier than previously thought. These stones develop in patients within only a few months following the procedure rather than several months to years, according to research published in the June issue of the Journal of the American College of Surgeons.
