The most common cause of hematuria in humans with urinary tract stones is that the stones scratch the mucous membrane of the urethra in the process of discharge, which leads to the appearance of hematuria. In this case, patients can drink more water and urinate more often. If localized encapsulated stones are formed and remain stuck in place for a long time, timely and effective lithotripsy surgery is also required. In other cases, the urinary tract infection is secondary to a urinary stone, and the patient will experience more obvious symptoms of bladder irritation, such as urinary frequency, urinary urgency, and urinary pain. If urinary stones are complicated by urinary tract infection, the patient should first be treated for the urinary tract infection, and only after the infectious inflammation is completely cured can the treatment of the stones be carried out. There are also factors that the human body itself has abnormal coagulation function, when there are urinary stones repeatedly irritate the mucosa of the urethra, it is easy to have blood flow than ordinary people, so patients also need to clarify whether the coagulation function is abnormal.
