I can't answer for the O/C part, but if they have incontinence problems, there is physical therapy for that. I would not do surgery or go on Enablex/Detrol/Vesicare, etc until trying the physical therapy. I'm doing it currently. I could be the pelvic floor is not responding to signals about "holding it'. For whatever reason. Childbirth can affect it. Big babies can put a lot of weight on the area and stretch it too far.
Healing in Motion, in Ann Arbor, has a wonderful staff, good results, and I would recommend it.
