When the patient stood up, the catheter fell out.The balloon must have come off prior to then.We were doing the sensations test and the rectal balloon was inflated slowly.We never filled the balloon past 300 cc but the patient did not have a sensation of filling.We surmise that the balloon came off during that filling.We were going to do the expulsion test by injecting 50 cc of air into the rectal balloon and have the patient attempt to expel it in the restroom.But when the patient got up off the exam table to go to the restroom, it was then that the catheter fell out of the rectum and the balloon was missing.The doctor tried to find the balloon digitally, but could not feel it.The patient was also asked to try to expel it by straining, but the balloon was not expelled.The patient was instructed to try to expel it at home over night, but if she did not do so, she was to return to the clinic and the doctor was going to use a scope to try and find it.We do not know the outcome after this.
