Blood in urine needs further investigation. In order to determine the cause and how to treat it, Dr. David Samadi recommends to rule out kidney cancer and kidney stones followed by a urine test for bladder cancer detection. Also, you may need to do a procedure called a cystoscopy. The purpose of the procedure is to diagnose, monitor and treat conditions affecting the bladder and urethra. This procedure can really save your life! What causes blood in urine? As with many cancers, bladder cancer’s precise causes are unknown. However, research has demonstrated that a variety of cancer-causing agents found in the urine may facilitate the development of the disease. Cigarette, cigar and pipe smoking have been shown to be a causal factor in roughly 50% of bladder cancer occurrences. Please Contact a Doctor if Any of These Symptoms Occur: • Uncomfortable temporary retention of urine; • Inflammation of the lumbar area; • Spasms or pain in the pelvic area or groin; • Chronic bladder inflammation.
