Are Vaginal Tears, Common With Robotic Hysterectomy?

I HAD A ROBOTIC HYSTERECTOMY IN SEPTEMBER AND THIS LAST WEEK ENDED UP WITH A TEAR AFTER INTERCOURSE WITH MY HUSBAND. THE DOCTOR SAID THAT SHE MADE MY VAGINAL CUFF TOO THIN. DOES THIS SEEM TO BE A GROWING PROBLEM WITH ROBOTIC HYSTERECTOMY AND HOW DO I KNOW IF THIS IS GOING TO HAPPEN AGAIN?
