Association of urinary and anal incontinence with measures of pelvic floor muscle contractility.

OBJECTIVE: To assess the association between clinical and sonographic measures of pelvic floor muscle (PFM) function and symptoms of urinary and anal incontinence (AI). METHODS: This was a retrospective study of women seen at a tertiary urogynecological unit. All women had undergone a standardized interview, clinical examination including Modified Oxford Scale (MOS) grading, urodynamic testing and four-dimensional translabial ultrasound (TLUS). Cranioventral shift of the bladder neck (BN) and reduction in the hiatal anteroposterior (AP) diameter were measured using ultrasound volumes acquired on maximal PFM contraction, blinded against all clinical data. RESULTS: Data from 726 women with a mean age of 56 ± 13.7 (range, 18-88) years and a mean body mass index of 29 ± 6.1 (range, 17-55) kg/m(2) were analyzed. Stress (SI) and urge (UI) urinary incontinence were reported by 73% and 72%, respectively, and 13% had AI. Mean MOS grade was 2.4 ± 1.1 (range, 0-5). Mean cranioventral BN shift on TLUS was 7.1 ± 4.4 (range, 0.3-25.3) mm; mean reduction in AP hiatal diameter was 8.6 ± 4.8 (range, 0.3-31.3) mm. On univariate analysis, neither MOS nor TLUS measures were strongly associated with symptoms of urinary incontinence or AI; associations were non-significant except for BN displacement/SI (7.3 mm vs 6.5 mm; P = 0.028), BN displacement/UI (6.85 vs 7.75; P = 0.019), hiatal AP diameter/AI (9.6 mm vs 8.5 mm; P = 0.047) and MOS/SI (2.42 vs 2.19; P = 0.013). CONCLUSIONS: In this large retrospective study we did not find any strong associations between sonographic or palpatory measures of PFM function and symptoms of urinary incontinence or AI.

The bother of anal incontinence and St. Mark's Incontinence Score.

BACKGROUND: Patient self-report is important in the assessment of the impact of anal incontinence (AI) on quality of life. This study aimed to (1) determine the correlation between total St. Mark's Incontinence Score (SMIS) and a single-item visual analogue scale (VAS) for bother from AI, and (2) determine the correlation between individual components of SMIS and VAS. METHODS: This is a retrospective study conducted on a cohort of 516 women seen for symptoms of lower urinary tract and pelvic floor dysfunction between January 2013 and August 2014. If a woman responded "yes" to the question "Do you experience any leakage from the back passage/anus?" they were considered to have AI, and the SMIS was administered. They were also asked "How much are you bothered by these symptoms?" to assess bother from AI by VAS. Statistical analyses were performed using Spearman's correlation and Mann-Whitney U test. RESULTS: Eighty-four (16.3 %) women reported AI with a mean SMIS of 11 (SD ± 5.11, range 2-24) and median bother of 5 (VAS 1-10). There was a fair correlation between VAS for the bother from AI and SMIS (Spearman's r = 0.523, p < 0.001). Fecal urgency, impact on lifestyle, and use of pad/plug were significantly associated with VAS (p = 0.05, p = 0.002 and p < 0.001, respectively). CONCLUSIONS: There is a fair, positive correlation between VAS for bother from AI and SMIS. Patients' bother from AI is strongly associated with its impact on lifestyle as quantified by individual SMIS components.
