Men with black solids in their urine may have stones or old blood clots.
1. Stones: If the patient has a history of kidney stones or bladder stones, and has recently had surgery to break up stones in the urethra, it is possible to discharge black solid material when urinating, and it is necessary to review the ultrasound examination of the urinary tract to see if the stones are discharged.
2. Stale blood clots: after patients with urinary bleeding due to various reasons, although the bleeding condition stops, but the formation of stale blood clots, along with the urine out of the body, may lead to black solid material in the urine.
When black solid material appears in men’s urine, they should immediately go to a regular hospital for detailed examination and treatment, and follow the doctor’s instructions so as not to delay the condition and cause adverse consequences.
