The stone cannot urinate, which means that the stone is blocked in the urethra. In this case, there are three ways to deal with the problem: 1. If the stone is stuck in the external orifice of the urethra, it can be crushed with a vascular clamp and then removed. 2. If the stone is stuck in a deeper position, it can be effectively pushed into the bladder through the upper ureter and then crushed by extracorporeal shock wave lithotripsy. 3. The stone is then broken up with the holmium laser. After shattering, the stones are flushed out of the body through the cystoscope. In this case, it is recommended to keep a urinary catheter in place after surgery, drink more water and take anti-inflammatory drugs to effectively promote the complete discharge of the stones and effectively prevent infection.
