Brief Summary

This is a single-center prospective cohort study sponsored by the University Hospitals Leuven (UZ). Women will undergo a pelvic floor ultrasound and will be asked to fill out a questionnaire at the time of their admission into the labour suite, at the postpartum check-up and 12 months postpartum.

The primary objective is to correlate self-reported symptoms of Pelvic Floor Dysfunction (PFD) (binary outcome) at one year after delivery with structural changes to the Pelvic Floor Muscles (PFM) and postpartum evidence of levator avulsion (binary indicator) as measured by TransPerineal UltraSound (TPUS).

Secondary objectives are to compare demographical and obstetrical variables between patients suffering from PFD symptoms or pelvic floor injury (documented one year after delivery) and those who do not; to record how patients manage and cope with PFD including recovery and compliance with Pelvic Floor Muscle Training (PFMT) as prescribed in the standard pathway of peripartum care; and to use of TPUS images for the development of artificial intelligence tools for automated image analysis.

Primary outcomes are PFD symptoms one year after delivery and injury to the PFM evidenced by POP-Q and TPUS. The demographic variables and information about the pregnancy and the delivery will be obtained from the medical records.

The presence and severity of PFD will be measured using standardized self-reporting tools: Pelvic Organ Prolapse Distress Index (POP-DI), Patient Assessment Constipation-SYMptoms (PAC-SYM), International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-SF), St. Mark's Incontinence Score (SMIS), Female Sexual Function Index (FSFI), Female Sexual Distress Scale - Revised (FSDS-R). FSFI is a widely used generic tool with sufficient granularity and validated in a large number of languages. FSDS-R assesses the construct "personal distress", which has been considered as an additional important aspect contributing to sexual dysfunction of women.

PFD, as a clustered outcome, being the presence of any kind of pelvic floor dysfunction symptoms, will be defined as POP-DI score of ≥11 OR ICIQ-SF score of ≥1 OR SMIS score of ≥1 OR FSFI score ≤ 26.55 OR FSDS-R score ≥11.

Primary Outcome Measures
NameTimeMethod
Anal Incontinenceone year postpartum

St Mark's Incontinence Score (SMIS) ≥1 (score range 0-24, higher scores mean worse anal incontinence)

Constipation according to the Rome IV criteriaone year postpartum

Must include two or more of the following:\*\* Straining during more than ¼ (25%) of defecations Lumpy or hard stools (Bristol Stool Form Scale 1-2) more than ¼ (25%) of defecations Sensation of incomplete evacuation more than ¼ (25%) of defecations Sensation of anorectal obstruction/blockage more than ¼ (25%) of defecations Manual maneuvers to facilitate more than ¼ (25%) of defecations (e.g., digital evacuation, support of the pelvic floor) Fewer than three SBM per week Loose stools are rarely present without the use of laxatives Insufficient criteria for irritable bowel syndrome

Urinary incontinenceone year postpartum

International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-SF) score of ≥1 (score range 0-21, higher scores mean worse urinary incontinence)

Sexual dysfunctionone year postpartum

Female Sexual Function Index (FSFI) score ≤ 26.55 (score range 2 to 36, worse scores mean worse sexual function) OR FSDS-R score ≥11 (score range 0 to 52, with higher scores indicating more sexually related distress)

Secondary Outcome Measures
NameTimeMethod
bladder neck mobility1 year

axial descent of the bladder neck during Valsalva manoeuvre

levator hiatus antero-posterior diameter (cm)1 year
levator hiatus latero-lateral diameter (cm)1 year
anal sphincter injury1 year

residual defect of at least 30 degrees on Tomographic Ultrasound Imaging

levator avulsion1 year

complete avulsion is defined as complete detachment of the puborectalis part of the levator ani muscle from the inferior pubic ramus on 3 out of 8 tomographic ultrasound imaging slices of the pelvic floor during contraction

levator hiatus surface (cm2)1 year
co-contraction1 year

approximation of the dorsal puborectalis to the symphysis pubis during Valsalva manoeuvre

pelvic organ descent1 year

descent of bladder/cervix/ampulla rectalis under the level of the symphysis pubis
