As I understand it, venous stripping seeks to cure E.D. by restricting the leakage (venous leakage) that drains the corpus cavernosum in the tunica albuginea. That leakage deflates the erection.
Venous stripping might work. But you should rigorously determine if it is likely to.
Ask, and get definitive answers before proceeding. There IS downside risk!
Of course, if your E.D. is NOT caused by leakage, this treatment misses the mark completely and will be a complete failure.
If your leakage is NOT in the veins treated, it will be like patching an inner tube in the wrong place. Complete failure.
Note that "venous leakage" is not the only leakage that could be taking place. If your tunica leaks, you are patching the wrong place. Complete failure.
If the vein(s) treated ARE the problem, you may get relief. That relief may or may not be permanent. Partial success or temporary success or temporary partial success. Or maybe 100% success.
So, you try to get a pinpoint diagnosis. Is my problem VL? If so, exactly where is the leakage and is that location treatable? Is there any other leakage going on (if you don't patch all the leaks, the treatment will not succeed very well)?
Granted that VL/VS surgery is less invasive and destructive than an implant, but to do it right you must lay the groundwork.
The auto mechanic's "hit or miss" method; your engine doesn't run right? Lets start randomly fixing parts and see if anything works - swap out the spark plugs, No? swap out the starter motor. No? Replace the thermostat. No? change the fuel filter. Hey! what do you know!. It worked. (Note that chose more-invasive solutions first, but not the most invasive one-rebuild the engine.)
