I had brachytherapy 20 years ago for elevated PSA.  So far, PSA has remained at essentially zero.  Shortly after that treatment I developed gross terminal hematuria in the form of a clot every 3 months or so.  No other symptoms.  Two years ago on the advice of my physician I had a complete workup to try to find the cause.  Urology scope, Cat scan, the works.  No cause found. 

Two months ago while in Florida I returned to the urologist who did my initial workup for brachytherapy.  He did a cystoscopy and found a "weak spot" in my bladder that he treated with cauterization.  Overnight my penis atropied to the size of a 7 year old's.  Not being circumcised I have trouble finding the darn thing to pee.  Erection is nonexistent.

Viagra doesn't produce anything but a headache.  Stimulation produces nothing but embarrassment. 

Can anything be done?
