Can 1 centimeter stone be discharged in ureter

The

ureter is a tube that connects the kidney to the bladder, and its diameter is about 3-4 mm. However, the 1 cm stone will get stuck in the ureter, and the diameter of the tube is obviously unable to accommodate it. Therefore, it is difficult for the stone to pass out by itself, and there is a high risk that it may lead to ureteral obstruction and hematuria. If a 1 cm ureteral stone is actively presented to the hospital, an external vibrator or sonic lithotripsy instrument is used to break the stone into smaller particles, which may be expelled from the ureter. If the patient has severe symptoms, endoscopic lithotripsy is usually recommended for improvement.
