I realized that I had a urethral stricture at the position of the fossa navicularis (about 1 inch from tip of penis). At about 10 days post surgery my stream became very narrow. Cystoscopy confirmed this. I was given a few options for treatment, including more surgery. Instead I decided on weekly self catheterization using Fr14-16 catheters to keep the stricture from reforming.

More than likely the stricture occurred due to the tools used for this transurethral procedure. Good luck.
