A 6.5mm stone in the ureteral shift is usually associated with metabolic abnormalities, urinary tract obstruction, infection, etc. It can be treated conservatively or surgically in conjunction with the cause. 1. Abnormal metabolism: Metabolic abnormalities that lead to high levels of oxalic acid or uric acid in the urine may lead to stone formation. The causative factor should be removed as soon as possible. If the content of uric acid and oxalic acid is too high, oral medication can be taken to promote the excretion of uric acid and oxalic acid, such as benzenesulfonic acid and phenylbromarone. 2. Urinary tract obstruction: when the urinary tract obstruction occurs, resulting in ureteral stenosis, easy to form stones. It is recommended to do more exercise and drink more water, which can accelerate the excretion. Patients with more serious obstruction need to undergo obstructive resection, and then take extracorporeal shock wave lithotripsy treatment. 3. Infection: for example, urethritis, pyelonephritis, etc., may cause the ureteral shift at the stone. Oral antibiotic treatment for this factor, such as cefadroxil capsules, levofloxacin capsules, etc., after the elimination of inflammation can assist in the expulsion of stones, such as the inability to expel, the feasibility of percutaneous nephrolithotomy. Ureteral migration of 6.5mm stones, can first go to the hospital to check, analyze the cause of the disease and then carry out treatment. Specific medication regimen should be carried out under the guidance of physicians to avoid unauthorized use.
