Patients with urinary tract stones usually do not suffer from intestinal obstruction, but in extreme cases, such as retroperitoneal abscesses caused by urinary tract stones, or retroperitoneal infections causing perinephritis, intestinal obstruction can be caused, which is a dynamic intestinal obstruction. Because the nerves that govern intestinal peristalsis pass through the retroperitoneum, if there is retroperitoneal infection, the nerves can be stimulated to produce intestinal paralysis, and then the patient will not have intestinal peristalsis, resulting in abdominal distension, nausea, vomiting and other symptoms. If there is only a simple urinary tract stone and no retroperitoneal infection, then the intestinal obstruction is not related to the urinary tract stone. However, if there is extensive retroperitoneal infection combined with urinary tract stone, then the intestinal obstruction is related to the infection caused by the urinary tract stone, and these need to be further evaluated and diagnosed in the hospital after examination.
