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.
It might be a bladder or kidney stone, bobbling around causing irritation of the lining and therefore blood. Or it may be an early warning sign of a kidney cancer, ureteral cancer or even a bladder cancer. Whatever the cause, blood in the urine is not normal at any time and must be evaluated. Sure, if there is an infection, and thereâs no more blood after the infection is treated, then no further assessment is necessary. But that is because there was an obvious cause of blood, that when treated, resolved.
