Unfortunately, for a man with non nerve-sparing RP to regain erections without some assistance, some nerves have to have been left behind in error ... they can not replicate out of thin air. On that basis, it would be interesting to know what proportion of the 13% went on to have a recurrence.
Not sure that robotic surgery would have a positive influence as all the data so far has shown that outcomes in terms of continence, EF and margins are slightly worse with robotic or standard keyhole than with open surgery.
Our uro also tells me that one of the biggest problems they have with collating outcomes data post-RP is the significant proportion of men who say that they have regained erections when they haven’t - apparently, asking the partners produces a different story.Still, an interesting review of the literature.
