One tube short doesn't matter?  Surgery is always risky. We don't know all the effects of lopping off a fallopian tube. When it is necessary, of course, it should be done. But if it can be saved and a less intrusive, less risky method is available, it is always preferable. "Going under" is not trivial, and neither is recovery from abdominal surgery. You seem to minimize very real risks. As has been said upthread, there are many states in which non-Catholic hospital and clinic care involves lengthy travel and thus is not an option.  

If hospitals were charities that are sponsored and supported by the church to meet a glaring need, you may have a point. But hospital systems are businesses, first and foremost. Catholic values are just lip service, far down on the list for Catholic health care organizations (ask any employee) while revenue streams and competitive advantage are at the top. It's not like women (or men for that matter) are requesting reproductive services from a church.
