Painful burning after ejaculation 1 year after PVP.

Hi. I am 62 yrs. old. In Aug. '07 I had PVP surgery after suffering 9 years with symtoms of an enlarged prostate. The operation was successful. My stream is strong and I get up only once at night to urinate. I got my life back. I don't have "urgency" issues and kayak, travel and basically enjoy life. I experienced many of the common post op complications, including the need for catheterization several days after surgery, passing blood clots and intense burning while urinating. After 6 months everthing was fine, except for one lingering problem. I experieced a burning sensation after ejaculation. I returned to my Doctor for some answers and he was baffled. The burning ranges from very intense to very mild. Now, 14 months after the sugery, I still have this lingering problem and no answers. Can anyone help?

Thanks,

JoeGil
