Which classification system is used to categorize uterine fibroids?

The FIGO classification system is specifically designed to categorize uterine fibroids, also known as leiomyomas. It organizes fibroids based on their location within the uterus, which can be critical for management and treatment decisions. This classification divides fibroids into subserosal, intramural, and submucosal types, each having different implications for symptoms, potential complications, and approaches to treatment.

The emphasis on the anatomical position in the FIGO classification aids clinicians in predicting patient outcomes and selecting appropriate surgical techniques or medical management. Understanding the location and type of fibroids is essential, as submucosal fibroids, for example, are often associated with heavier menstrual bleeding and infertility, whereas subserosal fibroids may lead to different clinical presentations.

In contrast, the other classification systems mentioned do not pertain specifically to uterine fibroids. The ACOG classification primarily addresses various obstetric and gynecological conditions, the TNM classification is used for staging cancers based on tumor size, lymph node involvement, and metastasis, and the BIRADS classification focuses on breast imaging assessments. Therefore, the FIGO classification is uniquely suited for categorizing uterine fibroids based on clinically relevant criteria.
