Whether the urinary stone is discharged or not can be confirmed by the patient’s subjective feeling, routine urinalysis, ultrasonography, X-ray examination and so on. 1. Subjective feeling: after the stone is discharged, the patient can feel that the obstruction disappears, and the urination is more freely than before the stone is discharged. In addition, patients can also feel the disappearance or weakening of lumbar pain and lumbar distension. 2. Urine routine examination: urine routine examination is a routine examination for patients with urinary tract stones. Kidney stone patients can have microscopic hematuria and elevated urine leukocytes after renal colic. When the patient’s stones are discharged, the relevant indicators can be improved. 3. Ultrasonography: ultrasonography is not harmful to patients. The echo of stones can be observed under ultrasound. When the patient discharges the stone, the echo of the original stone can be found to disappear through ultrasound observation. In addition, ultrasound can also observe the X-ray negative stones (uric acid stones, etc.), so as to further confirm whether the stones are discharged. 4. X-ray examination: X-ray examination can see the shadow of the stone, generally speaking, the higher the calcium content of the stone, the more obvious the shadow. Patients with discharged stones can find the disappearance of the stone shadow through this examination. However, there are some stones that cannot be detected by X-ray, such as uric acid stones, which are called X-ray negative stones. This type of stone requires ultrasound examination to confirm whether or not it has been discharged. For patients who need to confirm whether the stones are discharged or not, they should go to the relevant departments of regular hospitals as soon as possible, and be examined by specialized physicians, so as to avoid misdiagnosis and aggravation of the condition.
