Can primigravid stress urinary incontinence be predicted by translabial urethral motion profile ultrasonography?

To determine SUI prevalence and its association with urethral and bladder neck mobility among late third-trimester primigravid women. Stress urinary incontinence (SUI) is a relatively common urogynecological disorder in pregnant women that significantly disrupts their quality of life. Although its prevalence is increasing along with gestational age, there have been reports of underreporting due to various reasons. Therefore, a diagnostic modality is needed to determine the presence of SUI in such a population. A total of 209 late third-trimester primigravid women included in the study between November 2016 and July 2019 were examined by translabial ultrasound. Bladder neck descent (BND), retrovesical angle (RVA), urethral rotation (RoU) and funneling were observed in each patient. SUI was diagnosed using a cough stress test and Questionnaire for Urinary Incontinence Diagnosis (QUID). Thirty-five subjects from each group were randomly selected for further analysis. Among 209 late third-trimester primigravid women, SUI was observed in 57 patients (prevalence 27.3%). The RVA and funneling of the SUI group were significantly higher than the control group (P < 0.05). The BND and RoU were similar between groups. Identified risk factors of SUI were body mass index >23 kg/m2 and the presence of funneling in the translabial ultrasound. The prevalence of SUI among late third-trimester primigravid was 27.3%. Positive funneling and higher BMI were shown to be the independent risk factors for SUI.
