Evaluation of pelvic floor using 2D and 3D Transperineal Ultrasound

Pelvic floor dysfunction (PFD) is a prevalent condition affecting women worldwide and includes pelvic organ prolapse, stress urinary incontinence (SUI), fecal incontinence, sexual dysfunction, and vaginal laxity. Vaginal laxity is increasingly recognized as a distressing symptom negatively affecting quality of life and sexual satisfaction. It has been strongly associated with levator ani muscle overstretching and enlargement of the levator hiatus, particularly following vaginal delivery. Pregnancy and childbirth are major contributors to pelvic floor trauma \[2\]. Vaginal delivery may result in levator ani muscle injury, bladder neck descent, urethral hypermobility, and widening of the levator hiatus. These anatomical alterations predispose women to stress urinary incontinence and pelvic floor weakness. Transperineal ultrasound has emerged as a reliable, non-invasive, and reproducible modality for assessing pelvic floor structures. Two- and three-dimensional ultrasound techniques allow accurate measurement of bladder neck mobility, retrovesical angle, levator hiatus dimensions, and levator ani integrity during rest and Valsalva maneuver. However, limited studies have addressed the combined evaluation of vaginal laxity and bladder neck descent using both 2D and 3D transperineal ultrasound in parous women. Therefore, this study aims to evaluate these parameters and correlate them with mode of delivery and pelvic floor dysfunction symptoms
