Thanks for getting back to me, Andy and Pratap,
Andy, regarding the Stamey test, apparently no infection was found (I should say that I'm presently in Spain and interacting with the medical staff here can sometimes be a little difficult. Luckily you can download all of your test results from the Health Service app.). The only thing mentioned was that urogenital flora was detected in the seminal liquid but my GP said that was at normal background levels - apparently, no bacterial culturing was carried out. I realise this might cast doubt as to whether I have chronic prostatitis (CP); nevertheless, the only way I've been able to fight the swelling and reduced urine flow is by taking a course of antibiotics (it's worked twice before), thus suggesting a bacterial component to my problem. Anyway, my next urology appt. isn't until late October so I've been wondering if there is another antibiotic that might be effective against CP, or if I should be doing something else.
Pratap, regarding the radical prostatectomy (RP), I think the next time I see the urologist I will reluctantly ask him to go ahead with surgery (originally I was offered Active Vigilance, Radiotherapy or an RP, and I chose AV). My main concern re. surgery is if there are post-op urinary infections. I know it takes months to regain all function and that a certain percentage of people are unlucky with longer-term ED or incontinence. My dread would be to have repeated urinary infections requiring multiple courses of antibiotics, and the harm that can do to one's body overall. On the plus side, I'd be able to exercise properly again at some point - since the biopsy, any strenuous activity has led to swelling, discomfort, and affected urine flow.
The only other thing to mention is that I'm back to live permanently again in the UK when I'm 60 (in just over a year). I had hoped I could stay relatively stable on AV until then so that I could face any surgery back at home in Oxford, where I'm told the urology dept. staff are really good. However, after this current course of antibiotics, I fear I will be dealing with debilitating CP again relatively soon and be forced to ask them to intervene surgically.
Thanks again for your input, any advice you have is very much appreciated.
All the best to you,
Simon R
