If you want to know whether the stone is discharged or not after lithotripsy, you need to judge according to the type of lithotripsy surgery and the symptoms. Commonly used surgical methods include extracorporeal shock wave lithotripsy, open surgery, minimally invasive surgery, etc. After the surgery, you can combine the visual observation and auxiliary examination to find out whether the stone is discharged or not. 1. Extracorporeal Shock Wave Lithotripsy: This method utilizes shock waves to pulverize the stones, which will be discharged along with the urine after they become fine particles. At this time, you can observe whether there is abdominal pain, hematuria, whether there are gravel-like particles in the urine, etc., but also through the auxiliary examination, such as ultrasound, CT and so on. 2. Open surgery: If the patient adopts open surgery, the doctor will take out the whole stone during the surgery, and then, through ultrasound and CT examination, if there is no more stone, it means that the stone has been taken out completely. 3. Minimally invasive surgery: If minimally invasive surgery is used, the surgery will crush the stones, and then the stones will be suctioned and discharged. Generally, such stones are relatively small, and the patients will visualize the removal of the stones, which can also be checked by auxiliary examinations such as ultrasound and CT. To summarize, due to the choice of different methods of stone crushing, the discharge is also different, the patient can consult the attending physician.
