The new one incision hole surgery is suppose to dramatically lessen the amount of nerve damage. There are lots of men who have had surgery that have recovered and have a useable member. I would not take the risk on focal therapy because long term data does not support its use. “Need for Retreatment: About 20% of men may require additional treatments (either a repeat focal session or whole-gland treatment) within 5 years. “. (From the Cleveland clinic). Surgery cure is about the 91-95% range. Sad to say there are no guarantees, but more based on a case by case by competent surgeon and oncologists.
