Male ligation, also known as vasectomy, involves local infiltration anesthesia, then ligation of the vas deferens after it is located, and final suturing of the wound. It is recommended to consult the urology department in time and decide after the doctor’s comprehensive evaluation with the condition. Clinically, vasectomy is a type of vasectomy; first of all, it is necessary to improve the chest CT, liver and kidney function, electrocardiogram and other tests under the guidance of the doctor, to rule out contraindications to surgery. Before the surgery, local infiltration anesthesia is required under the doctor’s guidance. After the anesthesia takes effect, a local incision is made and the vas deferens is found for separation, then the seminal vesicle is perfused, and the vas deferens is fixed with vas deferens fixation forceps through the skin externally and hooked out of the body, and ligature is performed in the middle; finally, the vas deferens is retracted and the incision is closed, thus completing the vasectomy surgery. After the surgery, it may cause bleeding, infection, nodules, sexual dysfunction, reproduction and other complications; therefore, it is necessary to pay attention to local care, and should go to regular hospitals in time for consultation and treatment after any uncomfortable symptoms appear.
