Test shows that there is very little blood flow when flaccid and even erect flow is weak. Positive is that no venous leak cause no outflow
You may have ruptured an arteriole that branches from the cavernous artery. These small helecine arterioles fill the sinusoidal( cells) to provide plump engorged erections that fill the cavernosa to the max and that triggers the prevention of outflow. The growth of cavernosa and corpus spongiusm tightens and constricts the deep dorsal vein, which gives you a pipe-like turgid erection.
The color US Doppler will still show adequate filling BUT 70% is not optimum or acceptable.
I’ve sustained small glans and slight 5% curve ( mild Peyronie) from excessive pressures during penis pumping. Nothing over 15mm-Hg but still too long at 10-15 for too many sessions.It’s been over 8 years for me but I still keep my hope/faith.
I think that the only way to fix this would be to transplant new corpora tissue in the future. Lots of tissue engineering is being worked on constantly.
I’m not trying to scare you and I’m not saying with complete certainty !
However if your test shows no venous leakage, and your incoming arteries are not compromised ( good flow velocities), it could very well be that these small arterioles have been compromised.
We both would need a real good technician that can see any other remnants of said injury as advancement in technology has allowed visualization of hemodynamics at the sub-millimeter level.
