This study aims to evaluate vaginal laxity and bladder neck descent in women who have given birth, using non-invasive 2D and 3D transperineal ultrasound. Participants will complete a short questionnaire about pelvic floor symptoms and undergo a pelvic examination. The ultrasound will measure bladder neck position, levator hiatus dimensions, and related pelvic floor structures at rest and during straining. The study will compare findings between women with previous vaginal deliveries and those who had cesarean sections. Participation is voluntary, and all procedures are safe, non-invasive, and similar to routine clinical practice. The results will help better understand pelvic floor changes after childbirth and may improve the management of pelvic floor disorders.
