Let's see if I can help with some of your questions.
How long will surgery take? Really depends on what is being done, my TAH/BSO lasted a little over 2 hrs. (everything was removed)
What all will be removed? Only your doctor will be able to answer this one.
Adomnial incision? Vaginal? TAH=abdominal incision w/either a bikini cut just above the pubic bone or a vertical cut below the belly button down to pubic bone.
How long will I be in the hospital? TAH 2 to 5 days is normal/ TVH outpatient to overnight.
How long on bed rest? Straight bed rest is very rare, they want you up and walking to be able to expell your gas and get things moving again.
Any meds I need to stop taking prior to surgery? The doc will give you a list of what you can and can not take and when to stop meds if needed.
Do I need to start taking a vitamin? Ask your doc, also ask if you need to take iron pills.
What meds will I be on in the hospital? At home for pain? Again, it will depend on your doc and your history.
Will I wake up in alot of pain? You might, but I didn't. In fact I was never in pain once I woke up in recovery, they still pumped me with meds though.
Will I keep my appedix? Probably, I did.
Will I have a catheder(not sure of spelling)? If you have a TAH you most certainly will but don't worry, you will be very glad you don't have to get up right after surgery. No getting out of bed while on a pain pump.
If ovaries removed when will I start HRT? Ask your doc, I started mine the day after my op.
If I keep 1 ovary how long will it take to work post-op? Everyone is different so no one can give you an answer for sure.
Will I need prep before surgery..(shave, enema, etc...)? Most of us do have pre-op orders, just make sure you follow YOUR doc's orders to the T and no one elses.
When can I drive? This will be up to your doc but not usually until you are able to forcefully slam on a break pedal without pain.
How long off work? TAH 6 to 8 weeks/TVH can't remember.
What weight will I be able to lift once I am home? No more than a gallon of milk in most cases.
Hope this helps, I am 6 months post op and I for one have no regrets. I love the fact that I do not live life around my period any longer.
