Is it serious if a man suddenly urinates blood?

Whether a man's sudden hematuria is serious or not usually depends on the specific cause, and conclusions cannot be made blindly.

Male urinary tract infection or urinary tract stones and other benign diseases cause hematuria, which is generally not serious. Cooperating with the doctor to use antibiotics or removing the ureteroscope through surgical treatment, most of them can have a curative effect, which will help the hematuria stop and the body return to a healthy state, and will not cause harm to one's own life and health.

Hematuria caused by malignant urethral tumors or kidney tumors in patients is generally more serious, cannot be completely cured, and can easily shorten the patient's life cycle. It is necessary to cooperate with the doctor to treat it through various methods such as surgery or chemotherapy.
