I am a 22 yr old male. I underwent Right URS + Lithotripsy for a 1.7cm stone in my right ureter. The doctor placed a double J stent and said that he'll remove it after 4 weeks. Four days after the operation, I noticed urine droplets in my pants, my doctor said that it was because my stent has displaced a little bit. Yesterday as I was sleeping I had a feeling of nightfall, when I woke up my penis was erect and there was a pain in the lower part of penis but no ejaculation. I got curious and masturbated today, I got orgasm but not a single drop of semen ejaculated. Its been nine days since the stent was placed. I've read somewhere this can happen due to stent resting on prostrate or due to swelling in bladder after operation. I need expert advice on this. Is the ejaculation problem really due to the stent? Please help.
