At the Mommy Makeover Institute of Hawaii, any patient having a grouping of procedures that go over four hours gets a Foley caterer. This caterer and the urometer bag connected to it allow both the surgeon and the anesthesiologist the ability to know whether a patient is producing an adequate amount of urine to demonstrate her kidneys are correctly functioning while under anesthesia. It also prevents potential damage to one's bladder because fluids are being put into your circulatory system, however without a catherer, there is no way to get the fluids out safely.The compilation of surgeries that go to make a Mommy Makeover can be done safely as long as the Board Certified plastic surgeon and the Board Certified anesthesiologist follow standard surgical procedures.
