Patients with kidney stones who always want to defecate are advised to go to the hospital for examination. It is possible that the stones have been discharged into the lower part of the ureter, which causes a feeling of bladder irritation and rectal irritation, so the patient will always have a feeling of defecation. Ultrasound examination is needed to clarify whether the stone has already entered the ureter. If the stone has already discharged into the ureter, especially near the bladder end of the ureter, it is a normal situation for the patient to have the feeling of always wanting to defecate. However, if the location of the kidney stone has not changed and is still present within the kidney, the urge to have a bowel movement at this time is considered to be due to other diseases and requires a related examination at a gastroenterology or anorectal surgery department to clarify the cause. It may be due to a lesion in the rectum itself or infectious diarrhea that causes the urge to have a bowel movement. For the existing kidney stones, extracorporeal shock wave lithotripsy, medication and surgery can be considered to remove the stones as soon as possible to prevent further infection, hydronephrosis and kidney function damage.
