To determine whether the lower ureteral stone has been discharged from the body can be determined by physical examination, laboratory tests, imaging tests and other ways. 1. Physical examination: when the patient has no pain in the abdomen, the ureteral stone may have been discharged from the body, but this can not be sure that the stone must be discharged. 2. Laboratory examination: laboratory examination is mainly to check the blood and urine routine, especially in the urine routine there are no red blood cells, after the discharge of the stone within a short period of time after the urine test red blood cells can disappear. If the patient’s test results are not abnormal, the stone may have been discharged. 3. Imaging: Imaging mainly through ultrasonography, abdominal X-ray film, CT scan and other ways to check, you can clearly see the patient’s ureteral stones have been discharged from the body. Patients with ureteral stones should consult a doctor in time and follow the doctor’s instructions for examination. If the stone is not expelled, the patient should follow the doctor’s instructions for treatment.
