Prostate enlargement

Prostate enlargement [5] is a natural part of aging for men. Because of its location, an enlarged prostate presses against the urethra and prevents it from emptying urine from the bladder. This leaves you with a persistent urge to urinate and may result in microscopic hematuria.
Cancer
Blood in the urine is sometimes a sign of cancer [6] of the kidney, bladder, or prostate. This usually only happens in the advanced stages of cancer.
Other causes
Certain medications, such as blood-thinners, ant-cancer drugs, and penicillin, may cause visible blood in the urine. Parasitic infections, such as schistosomiasis [7], and inherited disorders [8] like sickle cell anemia, hemophilia, and Alport syndrome can also cause hematuria.
Conclusion
If you observe blood in your urine, you should see a doctor immediately. While the things it could mean may range from mild to life-threatening, only a doctor can make an accurate diagnosis of the cause.
