I Am Scheduled For Surgical Repair For Prolapsed Bladder On

I am scheduled for surgical repair for prolapsed bladder on April 1st. The surgery will involve hysterectomy to make room for prolapse repair. I am getting nervous about the mesh to be used in this repair along with removing healthy female organs. I really have no problems with prolapse but was told by a VA doc that I should get repair done "while there was viable tissue available to work with ." I am 69 years old. Should I go ahead with surgery or would it be ok to wait til I have problems. thank you so much
