Patients with kidney stones need to decide on a treatment plan based on the size of the stones, which determines whether hospitalization is necessary. For kidney stones smaller than 1.5 cm, extracorporeal shock wave lithotripsy can be utilized, allowing the patient to avoid hospitalization. After treatment, the patient can go home, where it is advised to engage in physical activity, drink plenty of water, and urinate frequently to facilitate the expulsion of the stones. A follow-up ultrasound of the urinary system should be conducted one week later at the hospital to monitor the status of the stone expulsion. If the stones are larger than 1.5 cm, surgical treatment is required, which necessitates hospitalization.
