Mituhashi, Youji, Ohmura, Gen, Amano, Youko[Abstract]　We developed a new catheter stent as a safe, easy and effective treatment method for cervical stenosis. Two postmenopausal women with pyometra were treated using a new catheter stent. The cervical canal is identified with a uterine sound under ultrasound guidance. A sterilized catheter stent using a nelaton catheter is then placed in the cervical canal for 3 months because of increasing re-stenosis of uterine cervix placing the another catheter within 2 months. Resolution of pyometra was achieved in both patients immediately after catheter stent insertion. At follow-up after removal of the tube, there was no evidence of recurrence of cervical stenosis. The new catheter stent can be placed for a long period and removed easily without any sutures or specialized instruments. There is no need for general anesthesia during our management procedure, which is beneficial in the office setting. This temporary catheter stent is both effective and safe in the treatment of cervical stenosis.
