Hematuria: Hematuria is blood in the urine. You need a complete urologic evaluation that can involved bladder testing, a kidney scan, and sometimes other urine testing. It is important in this case to rule out cancer, especially if you are a smoker.

Hematuria: Blood in the urine can be several things. Kidney stones or stones in the ureters (tubes leading from the kidneys to bladder) can cause blood. A bladder polyp can do the same thing if it ruptures. A prostate infection or bladder infection can lead to the same. Now.."a lot of sand"; he is likely referring to casts in the urine or sediment from the kidneys. You may need to see a urologist.
