Bleeding post Stent removal, ureterosco.

Hi, I had went under PCNL for kidney stone (20 mm approx) removal from my Left Kidney 35 days ago. A stent was placed which was removed 20 days ago & ureteroscopy was also done. Since then I have been on Faronem +Veltim-s for a week, Then I was on zenflox+Alfoo for another week and now I am on Uripil. Initially right after the stent removal, I experienced severe burning in urethra while urinating and after that with blood discharge at high level. But as I continued taking the above prescribed medication from my surgeon it decreased gradually. One of the major problem was I felt severe discomfort during erection. Still today as I am on uripil, It burns while urinating, 1-4 drops of blood pass out right at the end of urination and erection still hurts. Kindly suggest..
