Rezum Q&A
Q.Are there any precautions after the procedure?
A.A catheter may need to be maintained for approximately 2–3 days after the procedure. Even after catheter removal, some pain and minor bleeding during urination may occur, but these typically resolve within 1–2 weeks.
Q.How much pain is there during and after the procedure?
A.The procedure is performed under local or sedation anesthesia, so pain during the procedure is minimal. Temporary urinary symptoms such as urgency and frequency may occur for a few weeks during recovery.
Q.When can I return to daily activities?
A.Most patients can return to normal daily activities within a few days after the procedure. Strenuous exercise is recommended to be avoided for about 1–2 weeks.
Q.Can erectile dysfunction or sexual function issues occur after the procedure?
A.Clinical studies confirm that Rezum preserves sexual function, including both ejaculatory and erectile function. This is one of the key advantages over traditional surgical methods.
