Causes of a blood clot, or hematuria, in male urine include urinary tract infections, kidney stones and an enlarged prostate, states Healthline. Patients with this condition should receive medical treatment to prevent other health conditions such as cancer and kidney disease.
Urine that contains blood appears red, pink or maroon, and the patient may or may not see blood clots, reports Drugs.com. Infections in the urinary tract occur when bacteria enter the body through the urethra, the tube that carries urine from the bladder. The bacteria multiply in the bladder, causing symptoms such as pain and burning with urination, strong-smelling urine and a persistent urge to urinate, notes Mayo Clinic.
Kidney stones, which are crystals that form from urine, are also a common cause of hematuria. They develop in the bladder or the kidneys, causing pain and blockage that result in blood in urine, states Healthline. Additionally, an enlarged prostate, which is a male gland located just below the bladder and near the urethra, compresses the urethra, blocking urine flow. Symptoms include an urgent need to urinate, difficulty urinating and blood in the urine, reports Mayo Clinic.
Other causes include kidney disease, cancer of the bladder or kidney, medications such as aspirin and blood thinners, and blood disorders such as hemophilia and sickle cell anemia, according to Healthline.
