The fact that your bladder had to be pulled up (? stress incontinence) and your uterus is falling down (prolapse) suggests that you have a loose or dysfunctional pelvic floor. This is usually associated with multiple pregnancies.
A Tummy Tuck will NOT interfere with your pelvic floor except for a temporary increase in the intra-abdominal pressure and, barring any other serious medical issues or contraindications, could probably be done safely today. However, it would be a shame to have you have a flat tummy from a Tummy Tuck and then require having a Hysterectomy or formal bladder suspension through your new flat abdomen.
I would check with your GYN and Urologist or Uro- Gyn to see if you may benefit from any of these procedures BEFORE a Tummy Tuck is done. If this is the case, I would get the GYN procedures done first and then proceed with a Tummy Tuck either at the same time or a few months later, depending on your risk factors.
This would result in a much flatter new you without having a potential scar hanging over your head.
Good Luck.
