My doctor said that the fluid is permanent and the way he explained it, it was a result of PAST inflamation, so at least to my understanding he didn't sound like he thought somthing like antibiotics would help at all... He suggested Essure placement as an alternative to surgically removing the tubes. This is a way to block the end of the tubes that goes into the uterus and effectively stop the hydrosapalinx. It is marketed as a premanent birth control option, but there are several studies on using it to treat hydrosaplinx for IVF. If you search arabella's posts, she just had this done and has included a couple links to studies regarding essure placement. I'm actually going to have mine placed later this month!
