Pelvic Floor Dysfunction; Vaginal Laxity; Bladder Neck Descent in Parous WomenVLBNDUSNCT07491224
Evaluation of Vaginal Laxity and Bladder Neck Descent in Parous Women Using 2D and 3D Transperineal Ultrasound
An observational study of Pelvic Floor Dysfunction; Vaginal Laxity; Bladder Neck Descent in Parous Women, run by Assiut University.
Trial summary
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. Read more about this study

Study population: The study population consists of parous women attending the Women's Health Hospital, Urogynecology and Advanced Ultrasound units. Participants will include women with at least one vaginal delivery or only cesarean deliveries, aged 18 years or older. They will be recruited to assess pelvic floor function and anatomical changes using 2D and 3D transperineal ultrasound.

About this study
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.
Read the detailed description
Pelvic floor dysfunction is a common condition affecting women after childbirth, often resulting in vaginal laxity, bladder neck descent, and related pelvic floor symptoms such as urinary incontinence and sexual dysfunction. This observational cross-sectional study will assess 185 parous women, aged 18 years or older, using both 2D and 3D transperineal ultrasound. Participants will complete the Pelvic Floor Distress Inventory-20 questionnaire and undergo a pelvic examination using the POP-Q system after bladder emptying. Ultrasound measurements will include bladder neck height, retrovesical angle, levator hiatal dimensions, levator ani muscle integrity, and other related parameters at rest and during Valsalva maneuver. Women will be categorized based on mode of delivery (vaginal vs cesarean) and results will be analyzed to determine correlations between pelvic floor anatomy and symptom severity. The study aims to provide a comprehensive understanding of pelvic floor alterations in parous women, which may inform clinical assessment and management strategies for pelvic floor dysfunction.
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Vaginal Delivery (VD) | Women who have had at least one vaginal delivery. Participants will undergo pelvic floor evaluation including 2D and 3D transperineal ultrasound, complete the Pelvic Floor Distress Inventory-20 questionnaire, and undergo POP-Q clinical examination. No therapeutic interventions are assigned. | |
| Cesarean Section (CS) | Women who have had only cesarean deliveries. Participants will undergo pelvic floor evaluation including 2D and 3D transperineal ultrasound, complete the Pelvic Floor Distress Inventory-20 questionnaire, and undergo POP-Q clinical examination. No therapeutic interventions are assigned. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Levator Hiatal Area
Levator hiatal area will be measured using 2D and 3D transperineal ultrasound in the midsagittal plane. Measurements will be taken at rest and during maximal Valsalva maneuver to assess pelvic floor anatomy in parous women and compare between vaginal delivery and cesarean section groups.
Measured: Measured once during ultrasound assessment after bladder emptying
