Periods usually stand in for menstruation. A small amount of bleeding may occur during stone removal, but usually not as much as with menstruation. For patients with stones in the urinary tract, by repeatedly releasing energy to break up the stones in the body, so that they are discharged from the body with the urine, if the energy to break up the stones is relatively large or the brittleness of the local capillaries is relatively large, then the symptom of hematuria will occur, but not as much as menstrual blood, usually lasting 2-3 days can be relieved on their own. If the patient bleeding like the usual amount of menstrual bleeding, we should be alert to the occurrence of urethral injury or ureteral injury, if the symptoms of blood in the urine can not be relieved, it is recommended that the patient go to the urology department of the regular hospital as early as possible to improve the ultrasound and other related examinations, to clarify the cause of the disease under the guidance of the doctor to be actively treated.
