The hematuria caused by kidney stones needs to be combined with the length of time the stones have been irritating the body. Kidney stones cause patients to have hematuria, mainly due to the stimulation of the mucous membrane of the urinary tract by the stones, especially in the process of stone activity, which can damage the mucous membrane and lead to hematuria. Patients may also be accompanied by abdominal pain, urinary frequency, urinary urgency and other symptoms, which need to be clearly diagnosed by ultrasound examination of the urinary tract. If the stone is large and relatively stable, the duration of hematuria is shorter and may last for a few minutes. If the stone falls into the ureter, it will repeatedly irritate the ureter with hematuria until the stone is completely removed from the urethra, and the hematuria will slowly ease. Therefore, when a patient has hematuria in the naked eye, he should seek medical examination in time to clarify the location and size of the stone and then consider how to treat it. In addition, patients should pay attention to drink more water and exercise in moderation, which can promote the discharge of small stones and can effectively prevent the stones from continuing to develop.
