Re: urethral stricture surgery question
You will not get 50% chance of cure with a repeat urethrotomy - especially when you've had recurrence in just a few months. A repeat urethrotomy now is a palliative treatment only. I'm not allowed to quote sources in the medical literature here, but believe me, there are lots and lots of them.
Under ideal conditions, with a short (<1cm), superficial, previously untreated, single stricture, located in the bulbar urethra, a urethrotomy might have a 50% chance of cure, though that's somewhat questionable.
If the same stricture had been treated with an anastomotic urethroplasty - excising the strictured section - you might well have an 80-90% chance of cure.
If the stricture is longer (and doing urethrotomies will tend to extend the stricture), urethroplasty might require tissue grafts. This may not give as good a chance for permanent cure, but it still has far better long-term success rates than repeat urethrotomy.
In my own case, after failed urethrotomies, I had urethroplasty with buccal mucosa graft in 2006, on two strictures (the original one, and another one resulting from the previous surgery). Doing well so far.
I am always horrified when I read the experiences of people who keep on having urethrotomies and dilatations over and over again, year after year. Personally, I would never go back to that. Even if I do need another procedure in the future, I would absolutely stick with urethroplasty again.
