Kidney stones trying to poop and not being able to poop may be caused by the stone getting stuck in the end section of the ureter and irritating the rectum, but it may also be caused by concurrent intestinal disorders. If the kidney stone is dislodged into the ureter, it becomes ureteral stone. If the stone is stuck in the end of the ureter during the process of moving, it may cause severe pain in the lower back and abdomen, accompanied by nausea and vomiting, etc. Because the end of the ureter is close to the rectum, it may irritate the rectum, and the symptom of wanting to poop but can’t poop out may occur. In addition, if kidney stones occur with gastrointestinal diseases such as enteritis, the symptom of wanting to poop but not being able to do so may also occur. Therefore, if you have kidney stones, you need to go to the hospital to have a relevant examination in order to clarify the cause of the disease and then treat it.
