Summary: | Objective
To propose a new classification system (Urman‐Vitale Classification System) for intrauterine adhesions (IUAs) and to evaluate anatomical and fertility outcomes after hysteroscopic adhesiolysis accordingly.
Methods
A retrospective analysis of consecutive patients treated over 11 years by a single operator in a tertiary care hospital. Women with sonographic suspicion of IUAs were scheduled for hysterosalpingography (HSG) and hysteroscopy for confirmation and treatment. IUAs were divided into five classes according to symptoms, ultrasound, HSG findings, and postsurgical hysteroscopic appearance. Hysteroscopic adhesiolysis was performed using a bipolar cutting electrode in an office setting. Evaluated outcomes were restoration of the uterine cavity, clinical pregnancy, pregnancy loss, and live birth rates.
Results
A total of 227 patients (479 procedures) were included. Mean number of hysteroscopies increased in frequency with class of adhesions from Class 1 to Class 5 (1.0 ± 0.2 vs 2.3 ± 0.5; P = 0.001). Full restoration of the cavity was achieved in 100% of patients with Class 1 compared with 18.5% for Class 5 (43/43 vs 5/27; P = 0.001). Clinical pregnancy (Class 1 vs Class 4: P = 0.034; 1 vs 5: P = 0.006; 2 vs 5: P = 0.024) and live birth (Class 1 vs Class 4: P = 0.001; 1 vs 5: P = 0.006; 2 vs 4: P = 0.007; 2 vs 5: P = 0.0208) rates decreased with increasing severity of IUAs. Pregnancy loss rate was related to IUA severity (Class 1 vs Class 4: P = 0.012; 1 vs 5: P = 0.003: 2 vs 4: P = 0.014; 2 vs 5: P = 0.021).
Conclusion
A classification based on symptoms, imaging findings, and postsurgical macroscopic appearance of the uterine cavity could be useful in predicting prognosis and fertility in women with IUAs.
Synopsis
A new classification for intrauterine adhesions based on symptoms, imaging, and hysteroscopic appearance of the uterine cavity could simplify postsurgical prognosis and fertility. |
