Full Answer

Kidney stones are solid crystal masses that form in kidneys, urinary bladder, urethra or ureters, and are always accompanied with pain, states Healthline. Other than bloody urine, kidney stones may cause frequent urination, nausea and vomiting, odor in the urine, and high body temperature. Benign prostatic hyperplasia is the inflammation of the prostate gland, which causes exertion of pressure on the urethra. The pressure compresses the urethra, hindering urine flow through it, and eventually causing bloody urine, among other symptoms such as difficulty starting urination and a feeling that there is urine in the urinary bladder even after urination.

Urinary tract infections commonly occur when bacteria, viruses and fungi attack the kidneys, urethra, urinary bladder or ureters, and include cystitis, urethritis and pyelonephritis, notes Healthline. Besides bloody urine, these infections may cause burning sensation while urinating, frequent urination accompanied with little urine passage, and pain in the pelvis and rectum among women and men respectively. Obstructive uropathy is a condition in which a person experiences little or no flow of urine in the ureter as a result of blockage of the tube, leading to bloody urine and other symptoms.
