Clinical Grade of Obstetric Anal Sphincter Injuries and Prediction of Mode of Birth Recommendations: A 20-Year Retrospective Analysis.

ABSTRACT:

Objective

To determine whether assessment of symptoms and clinical grade of obstetric anal sphincter injuries (OASIs) is predictive of subsequent endoanal ultrasound (EAUS) and anal manometry (AM) findings to guide mode of birth recommendations.

Design

Twenty-year retrospective analysis.

Setting

Tertiary urogynaecology unit.

Population or sample

Women (n = 607) with a history of OASI in the second half of a subsequent pregnancy, 2002-2022.

Methods

A St Mark's Incontinence Score (SMIS), AM and EAUS were completed. An elective caesarean section (ELCS) was recommended if there was an external anal sphincter (EAS) defect and an incremental maximum squeeze pressure (IMSP) < 20 mmHg.

Main outcome measures

Accuracy, sensitivity, specificity, negative and
