Penile injury: Artery leaks blood so can't get hard. Anyone else

Was having sex with my girlfriend last summer and wrenched my penis (long story).

Have not been able to get erections since. They finally diagnosed it as an "post Traumatic AV fistula"
at the base of the penis. Meaning, the artery where the blood would go to fill up and make the Penis hard,
that artery has a hole and leaks blood into the vein next to it.

My urologist has never even seen a case like this. There are radioligical surgeons who can plug that hole,
but the success rate is between 10-30%! That seems crazy to me!

In this age of micro surgeries, there has to be a way to repair this.

Anyone else have a problem like this?

Thank you
