Patients and doctors are confused about the management of small intrarenal stones. If we don’t treat it, it will cause pain and hematuria frequently, and we have to worry about its growth; if we treat it, it is extracorporeal shock wave lithotripsy, but sometimes the lithotripsy can’t be removed, but if we use surgery, we think it is not worthwhile, so usually doctors will let patients wait for observation. However, our clinical observation shows that the stones will definitely grow bigger and bigger, and grow more and more. When the stone grows, we can only do percutaneous nephrological surgery, which is a significantly higher risk of surgery. More importantly, stones in the kidney can sometimes cause unpredictable damage to kidney function, causing hydronephrosis and kidney atrophy, as well as inducing chronic infections that can lead to decreased kidney function. As a foreign body in the body, stones can also stimulate inflammation in the kidney and, in rare cases, induce squamous kidney cancer. In our daily work, we also encounter patients who suffer from uremia caused by untreated kidney ureteral stones, in which case the cost of health and money will be even higher. At present, our recently introduced ureteral soft lithotripsy and stone extraction technology is most suitable for dealing with small intrarenal stones, which just allows for early treatment of kidney stones, thus enabling doctors and patients to achieve a two-pronged treatment strategy.
