Doctor Paulo Egydio is a world authority on Peyronie's Disease, which was the subject of his doctoral thesis.
He is the inventor of the famous Egydio technique to correct PD and a personal hero of mine.
His Medical Center in Brazil welcomes patients from all over the world.
More on the Egydio technique:

It looked to be quite interesting Flavio. However, the English translation was pretty awful, so I could not understand much of his discussion.
His explanation of a venous leak seemed to be in line with what I have discovered. That a venous leak is just CVOD. Which means it is anything that causes the venous occlusive mechanism in the penis to fail.
Even strong psychogenic factors can cause the venous occlusion mechanism to fail, simply because the smooth muscle in the erectile tissues is unable to relax due to the inhibitory forces working excessively. This prevents sufficient blood to flow into the sinusoidal spaces which will not create enough internal pressure to compress the veins under the tunica. The term venous leak is used very loosely by urologists to explain why you have ED. IMO it’s just like saying you have ED!
I did find the prosthesis explanation interesting as well. It appears from what I could understand that he preserves some of the corpus cavernosum (unlike what happens with a pump style implant). The prosthesis works like an aid to this rather than a complete replacement. This is interesting as it almost replicates what most other mammals have in their penis; a bone, to assist with erectile function. During our evolution we lost the bone in our penis’s. This is one reason why our erectile function is more inclined to be less reliable and more prone to failure as we depend solely on our hydraulic mechanism rather than a combined structure as our relatives have. This most likely occurred due to our standing and moving on just two feet, a bony penis would have become a hindrance and would most likely get damaged more easily during episodes of hunting and or fighting.
