The goal of this observational study is to evaluate the reproducibility of new 3D/4D ultrasound volume analysis techniques in the assessment of anal sphincter integrity and thickness in both pregnancy and immediate postpartum. The negative impact that OASISs (Obstetric Anal Sphincter Injuries), and possible subsequent anal incontinence, have on women's quality of life has stimulated research in this field in recent decades. However, there are still few studies concerning the topic. The transperineal approach by means of the transvaginal probe in the study of the pelvic floor, anal sphincter and related lesions has helped us to make strides in our knowledge of the anatomy of the pelvic floor and in defining the lesions that may affect it.
