quick update on my situation
Had another bladder neck incision, 3rd one, seems to just get narrower, fibrous growth - they had to use some force to open it up.
Had a supra pubic catheter put in- working well, and a relief after the pain of self catheterisation.
Had a urodynamic assessment and await the results on that.
2 litres of pee overnight on first night so was obviously retaining a fair bit. feel loads better.
Really not looking like my bladder neck will be ok, will discuss options in time i suppose.
All the best to everyone
Dave
