Answer 2

I'm no expert on pigs, but I think all mammals use pretty much the same system.  Urine produced by a fetus exits the body the same way it always does--the previous poster gave the pathway.  There can be no urine until after the renal system is developed, after all.

The urine is present in the amniotic sac--it is in fact most of what is called the "amniotic fluid".  The fetus actually swallows and re-eliminates it on a continuous bases.  (The fluid does not normally go into the lungs because they are not yet completely developed and are unexpanded in the fetus.  Aspiration of amniotic fluid or of meconium--the first bowel movement--is a serious complication in some births.)
