10 Cyst Symptoms
Blood in the Urine
Discovering a cyst on the kidneys may initially cause alarm, but they are rarely harmful and common occurrences. The fluid-filled sacs that form on the kidneys seldom cause complications. However, if they grow to a considerable size they may cause pain, become infected or cause other symptoms such as blood in the urine.
Blood in the urine, known as hematuria, occurs due to the kidneys or other parts of the urinary tract allowing blood cells to leak into the urine.
