Hello and hope you are doing well.
The post op inflammation and swelling could be causing the pain. As this settles, the pain should come down. Sometimes the pain could be due to an infection, so if the pain is worsening or if you develop additional symptoms like fever please consult your doctor. The stent will be removed through cystoscopy. In the meantime take OTC pain killers to help with the pain and plenty of oral fluids.
Hope this helped and do keep us posted.
