I'm not sure what: you mean by "your twists," but if you're talking about twisting exercises, it sounds muscular (back), not from your kidneys. If you're not sure, see your doctor to be examined. If you're having blood in your urine, that could be a sign of kidney disease and you should definitely get that checked.
