If it is just decreased a little, it could be a variant of normal. If it is absence of any fluid, it could be rupture of the membranes, absence of the kidneys, non function of the kidneys, genetic disorders or several others. If there is no water at all, inserting a needle into the amnion and infusing saline solution, can make it much easier to see the fetus. It also will allow one to withdraw some of the saline at the end and send it for chromosome anaysis of the fetal cells it will pick up. If the saline runs out the vagina as fast as it is run in, this proves rupture of the membranes. RDB
