I am very similar to you 12 weeks post RARP, two weeks of catheter, I am also on Gemtessa (not sure if I should refill it or not)
From what I have come across incontinence can last between 3 and 18 months for many men. We are just getting into the third month. I am going to give mine more time. I see a pelvic floor specialist pt for which I am very thankful.
I can see I am making progress ( morning are better, less tress incontinence, I am working on bladder re-training) I have a long ways to go but am inclined to keep working on pelvic floor rehab, bladder retraining, core training etc before I try an alternative
I wish you good luck
