Guide To The Causes Of Blood In Urine (Hematuria)

Polycystic Kidney Disease

Hematuria may develop due to polycystic kidney disease, a disorder where numerous fluid-filled sacs or cysts develop in the kidneys. These cysts take up space, crowding out and damaging the healthy cells that make up the kidney tissues. Polycystic kidney disease makes it difficult for an affected individual's kidneys to do their job and filter waste from the blood that flows through them. The kidneys in an affected individual may become enlarged and can fail as a complication of polycystic kidney disease. The fluid-filled cysts in the kidneys can cause the small vessels in the glomeruli to rupture or become damaged. This malfunction allows blood to leak into the urine being produced. Blood remains in the urine as it flows through the ureters to the bladder and exits the body.
