Bobdog, I had a laser procedure to remove calcium stones in my prostate and bladder neck in January, 2017, and have been incontinent ever since. Basically my internal sphincter (ie. the bladder neck) was compromised during the removal of these stones. In 2011 I had radiation treatment for prostate cancer, which effects the ability of tissue to heal. If the tissue in your bladder neck that is responsible for continence is missing, due to removal of the tissue during surgery, my guess is that you will not fully recover.
As you heal from the surgery your continence is likely to improve somewhat. During the first year after my surgery I had at least 6-7 UTI's. Whenever I get one my leakage increases significantly. I still deal with this problem, just not as much as during that first year.
