I would recommend having any medical issues resolved before undergoing an elective cosmetic procedure like tummy tuck, and that would include kidney stones. While the condition may be quiescent right now, what if you were to become slightly dehydrated, which sometimes happens following tummy tuck, and the stones worsened? Or if you started to pass a stone following tummy tuck and had intense nausea and vomiting, which often accompanies the passage of a stone together with nearly unbearable pain? I would not tempt fate on an elective case; see your urologist if you are really interested in a tummy tuck and have definitive treatment for your stones first.
