Urology/Urethra injury and mucus


I am a 39-year-old man who had a urinary tract infection several years ago. Since then at times I notice clear threads of mucus in my urine which I did not have power to the UTI. Why?this seems to occur when ever I feel irritation in my urethra where I previously had a structure which was dilated. The only thing I have ever been told is that when that structure gets irritatedit could cause some mucus.

Also, I was having relations with my wife and by accident she bit down and it is caused me to have tenderness in my urethra and what looks likemore clear mucus to occur. Is it likely this irritation will go away over time or is it anything to worry about?


Some degree of mucus is not unusual in the urine as the urethra tends to say a little moist, but this is not usually visible.  It sounds like you have a stricture which is a scarred, narrowed area in the urethra.  This stricture can cause a weak stream but usually does not cause excessive mucus production.  I suspect you may have a urethral infection.  Please check with your local physician.  If you notice the stream getting weaker, contact a urologist.
