Most urinary stones are single stones, i.e., only 1 stone, but some patients can have multiple stones, i.e., multiple stones. The stones are widely distributed, such as kidney stones combined with ureteral stones, or kidney stones combined with bladder stones, so the exact condition of the stones in the body needs to be determined based on the results of the examination. Single stones are usually cured by extracorporeal shock wave lithotripsy or surgery, but multiple stones or stones between different kidneys are more difficult to deal with. For example, for minimally invasive ureteral surgery, stones in one kidney can only be removed first, and then the stones in the opposite kidney can be treated at a later stage after the body has recovered well, or for stones in the same side of the urinary tract, stones in the ureter are usually treated first, followed by stones in the kidney. It is recommended that patients should go to the hospital to improve the relevant examination and assess the condition of the stone, and then develop the appropriate individualized treatment plan.
