Urinary stone infections discharging blood and blood spots may be associated with stones cutting through the mucous membrane of the urethra, as well as urinary tract infections. If there is a stone in the urinary system, when the stone is large or has irregular angles, it rubs excessively against the mucosa during the flow of urine, causing the mucosa to ulcerate and bleed. There may be blood mixed in the urine, which may appear as blood and blood spots. When combined with urinary tract infection, the pathogenic bacteria stimulate the mucosa, which can cause mucosal congestion, redness, swelling, bleeding, and the appearance of blood in the urine, usually accompanied by frequent urination, urinary urgency, urinary pain and other symptoms. When urinary stone infections appear hematuria, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
