Vacuum therapy with penile before revision

[Frenchboy]

Hello gentlemen,
Does it wise and don t I risk injury using a Ved before my revision ? I have to wait four months to get my surgery, have lost my residual erection for two years now. Before cylinder erosion I had really nice residual erection around the tubes. Now corporas have both shrunk, what a mess...

I have read that ved could be used before revision surgery, is it better to do it inflated, or uniflated ?
Any advice and testimony really appreciate. Thanks you in advance, Hope you are all well
