If you are talking just terms if body contouring you need a more comprehensive procedure to get the "best results". On the other hand you can still get a reasonably good result and either lose weight afterward to help the remaining contour issues or do the rest later. However, you apparently have sought this procedure in order to combine the bladder tack and the plastic surgery into the same anesthesia. That means that the operative time is extended due to the fact that you now have two operative teams that have to each set up and prepare the surgical site , do the procedure , and they follow each other. It is not done simultaneously. So, the plastic surgeon will follow the Ob-gyn and thus by the time he starts you will have already been under anesthesia for at least an hour if not more. So, it's not that you don't need lipo elsewhere, it's that it isn't safe to come in and do a truly comprehensive case of body contouring after another procedure , so your doctor is trying to give you most of what you want, yet keep you safe. If you want " the best results" and as you say " want as much gone as possible" ,you need to do the more comprehensive case another time and have lipo abdominoplasty (Saldanha technique) with UAL of your hips , flanks, and abdomen.This will allow you to have "as much gone as possible in one session". However, if you primarily want the convenience if a combined procedure then you are fine, but don't hold the surgeon to a standard that can't be met within the context of the combined scenario.
last if all, keep in mind the way doctors are rated on the Internet by rating sites are quite different than the way doctors rate other doctors. We tend to rate doctors by years of experience, surgical outcomes, safety, and inclusion in prestigious societies. Ratings sites are all over the map with everything from whether the doctors kept them waiting or even if someone in the office seemed short with them. In addition there are now doctors who are hiring companies to fabricate ratings and have even offered patients free services in exchange for high ratings. Due to these issues, we refrained from soliciting reviews from our patients. The fact that your Ob-gyn recommended the surgeon is good. The ratings on the Internet unfortunately are totally unreliable. Look for Society memberships , board certification , and such things over ratings. I wish you all the best.
