Stones are usually discharged in less than 1 week after lithotripsy treatment, and the discharge time varies depending on the lithotripsy protocol. Usually, the lithotripsy protocol needs to be chosen according to the size and location of the kidney stone as well as clinical symptoms and physical quality. For stones less than 1.5 cm in diameter, extracorporeal shock wave lithotripsy can be considered. Stones are crushed into multiple small stones, which are discharged one after another with urine, and the time of stone discharge can last about 3-5 days. About 1 week after the procedure, the urological ultrasound should be reviewed to check the stone crushing and stone discharge. If the residual stones are severe, another lithotripsy may be considered. If the stones are large, minimally invasive surgery should be considered to remove the stones through minimally invasive techniques such as ureteral and percutaneous nephrolithoscopy, which can basically remove the stones under direct vision, and if there are a few residual stones, they can also be drained through the drainage tube. During the stone removal process, pay attention to drink more water and exercise more appropriately to promote the urine to discharge the residual stones.
