Had same problem - also radical prostatectomy - now all good - no chemo or radiotherapy.
Can I advise all men over 45 to get at least an annual PSA bloodtest - it is not a very reliable test but it is all there is. If prostate cancer is detected soon enough it is cureable - if too late it is only treatable.All of us will get it if we live long enough so it is really a good idea to be regularly tested.
