The ductus arteriosus is a normal fetal artery connecting the main body artery (aorta) and the main lung artery (pulmonary artery). The ductus allows blood to detour away from the lungs before birth. Every baby is born with a ductus arteriosus. After birth, the opening is no longer needed and it usually narrows and closes within the first few days.
Welcome to our Guide for men who have noticed blood in their urine. The medical term for blood in the urine is hematuria. Urine that contains blood can appear pink, red, maroon, or even have a dark smoky color that looks like cola. You may or may not see blood clots, which can look like coffee grounds. Rarely, red urine may be caused by certain foods or medicine.
According to the Kidney Cancer Association, hematuria is the most common sign of kidney cancer. If you have blood in your urine, you may see pink, brownish, or even a red discoloration. Often even a small amount of blood can cause a color change. But, sometimes there is such a miniscule amount of blood that only a lab can detect blood during a urinalysis. Other causes of blood in the urine are bladder infection, kidney stone, cysts, or inflammation. If you see blood in your urine, it may be time to see your doctor.
