14mm ureteral stones are usually amenable to extracorporeal lithotripsy, but contraindications and special circumstances need to be ruled out. Extracorporeal lithotripsy is the release of energy through the shock wave generated by the extracorporeal lithotriptic machine to achieve the purpose of breaking the body stone. It is suitable for the treatment of kidney stones and ureteral stones. In the exclusion of contraindications, the whole ureteral stone can be extracorporeal shock wave lithotripsy, for the diameter of less than 10 millimeters of the upper ureteral stone preferred extracorporeal shock wave lithotripsy, greater than 10 millimeters of stones can be considered minimally invasive surgical treatment can be considered to perform extracorporeal shock wave lithotripsy. Pregnancy, uncorrected bleeding disorders and coagulation disorders, and severe cardiopulmonary disease are contraindications to ECT. In addition to the contraindications to extracorporeal shock wave lithotripsy, minimally invasive surgery is the preferred clinical option for ureteral calculi as large as 14 mm. If extracorporeal shock wave lithotripsy is chosen, the following conditions should be excluded: (1) hard stone with CT value higher than 1000; (2) renal insufficiency or obvious infection; (3) ureteral stenosis or obstruction distal to the stone; (4) polyp encapsulation for long time of obstruction; (5) combined with perirenal effusion or sole kidney need to relieve ureteral obstruction as soon as possible. Before extracorporeal lithotripsy treatment, relevant examinations such as coagulation time, platelet count, electrocardiogram, etc. should be done, and patients should be informed that some patients may have pain during lithotripsy. Symptoms such as hematuria, subcutaneous bleeding and pain may occur after lithotripsy, so consult the doctor promptly if there is any abnormality. For patients with 14mm ureteral stone, it is recommended to go to regular hospitals, combine with relevant examinations and choose the appropriate treatment plan.
