The Efficacy and Safety of Disposable Balloon Uterine Stent in Patients With Asherman Syndrome

Randomized, Controlled Trial to Assess the Efficacy of Disposable Balloon Uterine Stent and Foley Catheter in the Prevention of Adhesion Reformation After Hysteroscopic Adhesiolysis

Asherman's syndrome is characterized by the presence of intrauterine adhesions (IUA) as well as symptoms such as amenorrhea, hypomenorrhea, pelvic pain, and infertility. The gold standard for the treatment of intrauterine adhesions is hysteroscopic intrauterine adhesions. The recurrence of intrauterine adhesions is a major challenge in clinical practice. The isolation of barriers in the uterine cavity may be a measure to reduce postoperative re adhesion, but the effect of different devices is different. Therefore, this study was conducted.

The Foley catheter is usually inserted into the uterine after a hysteroscopic adhesiolysis and removed after on the 5-7th day after surgery. Several investigators demonstrated its favorable effect in the recurrence of adhesion after the treatment of intrauterine adhesion. Disposable balloon uterine stent is specially designed to fit into the cavity of the uterus, and usually removed on the 7th day after surgery.
