welcome to a great site and wonderful forum .....you are ;lucky to find it before your choices are made ... i wish i did it is a great knowledge base!!!
in my case i did not know much or was aware of researching pre surgery...i was monitored for about 2 years by my Urologist , which was mostly experienced with open RP, and due to my age and health i chose an open procedure.
I did consult with a rdiologist that was honest enough to recommand me a surgery again due to my age , health and good chances of recovery since i also had Organ confined cancer i chose open surgery.
At the time i had a choice of doing the DaVincie with my Surgen Partner , but being i trusted my surgen i chose the open procedure, however if i would change anything today it would be researching the DaVinci more and leaning to it for faster recovery, however i will still chose a removal of that thing OUT of my body and start a clean slate.
All procedure will have side effects to some extend , some longer term , and some shorter term , in my case i also wanted to leave the radiation option open JUST IN CASE!!! and did not want to take the chance that my nerves or other organs will be detirioating maybe few years down the road IF the radiation is of a stronger dose ...hjowever i hear alot with success story with other procedures as well
you must do your research, and recovery is slow BUT as you said 80% of success is up to the experiences your surgen have...i am 11 months out , was dry from the day i took my Cathtar out , ED is a longer process but significant improvement is showing in last couple of months as i had a nerve sparing operation...it does take between 6 to 24 months to get back to potency in MOST cases ...some lucky ones can gain it back in 10 weeks sometimes...
Good LUCK!! and keep us posted .... DO YOUR RESEARCH!! and make the choice that ONLY fits YOUR NEEDS !!!
