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.
Red urine may be a possible sign of cancer along the urinary tract-the growth of fragile blood vessels around the tumour can cause blood to seep into the urine. 'Seeing blood in the urine is associated with cancer in about one in five cases-most commonly bladder cancer,' explains Mr Laniado.
