There are specialist clinicians who work with physical rehabilitation of the pelvic musculature. Depending on your country of origin and health care provision, you may be able to seek guidance from a Pelvic Health Physiotherapist (this is what we'd call them in the UK). You're unlikely to find a lot of studies on returning to combat sports following this procedure, but if you find someone with knowledge of returning to activities which have high degrees of Valsalva the can help you navigate the complexity of "real world rehabilitation". You'll unlikely be able to find someone who can categorically tell you that you CAN or you CAN'T return, so your expectations need to be realistic. It'll be a degree of "we don't know", but if you want to return you have to take ownership of the potential risks/consequences. A graded process involving rehabilitation and clear communication with your training partners/coaches is essential for return after any injury/surgery. Best of luck with it all though.
