Thanks again everyone, lots to consider but I have a lot more idea going forward and hopefully be better prepared.
Hopefully I will have the results of my second urine sample this time tomorrow and get the all clear. I do still have some discomfort with my upset stomach, after taking laxitive on and off for few days, I am now too regular. Hopefully if my urine sample comes back negative then these other issues will not prevent me from going ahead. I will discuss these issues with my Urology department. Cheers again. Regards Dave
