Conditions that obstruct the flow of urine, such as kidney stones, tumors, or enlarged prostate (in men), can cause blood in the urine.
Symptoms may include difficulty urinating, lower abdominal pain, and urinary urgency.
Infections of the bladder or kidneys can lead to inflammation and irritation of the urinary tract lining, resulting in hematuria.
Symptoms may include fever, chills, abdominal pain, and frequent urination.
