Has anyone had TGR surgery for cystocele?

I am due to have surgery and feeling very anxious after previous failure of sacrocolpopexy to correct prolapse.I have been offered either traditional repair or tissue guided regenerative surgery with biomesh as a graft which dissolves after 3 months. 

I have opted for the TGR surgery which my UK surgeon says will do no harm even if it fails.(50% chance) Has anyone had this type of surgery with success? Recovery tips? 

What is a TGR ? X

Tissue guided regeneration. Using biological graft as a splint whilst own tissue heals. Graft/ mesh dissolves after 3 months after which time your own body has hopefully produced enough collagen to keep the repair strong. The principle is to detach and realign your own tissue. Had op.
