Correlation Between the Change in the Antero-posterior Diameter of the Pelvic Side and the Incidence of Post-partum Urinary Incontinence

Recruiting

• Conditions: Postpartum Urinary Incontinence

• Registration Number: NCT06812806
• Lead Sponsor: IRCCS Azienda Ospedaliero-Universitaria di Bologna

Brief Summary

During pregnancy, the strength of the pelvic floor muscles may decrease, which can lead to musculoskeletal changes that may facilitate the onset of urinary incontinence. The investigators decided to conduct this study firstly to analyze, through simple ultrasound indices, how the contractile capacity of the pelvic floor muscles affects postpartum urinary incontinence; secondly to study the correlation between the use of perineal gymnastics, the incidence of postpartum urinary incontinence, and the strength of floor contraction.

Detailed Description

As part of the gynecologic ultrasound that is routinely performed, a transperineal scan will be performed, at rest and during maximal contraction to measure the lower portion of the pelvic floor groove. I order tho achieve this, doctors will illustrate to participants first verbally and then with the visual aid of the ultrasound monitor, how to contract the pelvic floor muscles. Transperineal ultrasound is performed by placing the ultrasound probe covered by a sterile glove at the level of the labia majora. Such ultrasound does not involve internal investigations and is in no way painful. The duration of the additional ultrasound scan involves a few minutes. In addition, in order to assess the presence of typical symptoms of urinary incontinence, the participant will undergo a standardized validated questionnaire in the Italian language, called ICIQ-UI SF, consisting of a series of questions that will investigate the type of urinary incontinence, its severity and its impact on her quality of life in the four weeks prior to administration. After delivery, the participant's medical records will be consulted and some data regarding the participant (age, ethnicity, height, weight, BMI, parity, gestational age at the time of delivery), the delivery (duration of stage II labor, mode of delivery, any vagino-perineal laceration and its degree) and the newborn (weight and head circumference measurement) will be recorded.
