High-Density Surface Electromyography Assessment of Pelvic Floor Dysfunction in Women with Interstitial Cystitis/Bladder Pain Syndrome.

Up to 85% of women with interstitial cystitis/bladder pain syndrome have pelvic floor dysfunction and hypertonicity. Current evaluation methodologies lack objective measures of pelvic floor muscle activity. We examined the ability of using intravaginal high-density surface electromyography to quantitatively, objectively and noninvasively map pelvic floor muscle activity and innervation zone locations in patients with interstitial cystitis/bladder pain syndrome. Fifteen women with interstitial cystitis/bladder pain syndrome and 15 controls underwent 2 sessions of digital pelvic examinations and high-density surface electromyography assessments. The root mean squared amplitude of high-density surface electromyography was first calculated, and the resting root mean squared ratio was then calculated by normalizing the resting electromyography root mean squared to the peak electromyography amplitude reached during maximum voluntary contraction. Innervation zone distributions were obtained from decomposed high-density surface electromyography signals. The correlation between the root mean squared ratio and interstitial cystitis/bladder pain syndrome symptom scores and pelvic floor muscle alignment were investigated in patients with interstitial cystitis/bladder pain syndrome and healthy controls. Women with interstitial cystitis/bladder pain syndrome demonstrated significantly increased resting root mean squared ratios compared to controls (0.155±0.048 vs 0.099±0.041, p=0.0019). Significant correlations were found between resting root mean squared ratio and patient reported pain (rs=0.523, p=0.003), interstitial cystitis symptom (rs=0.521, p=0.003) and problem indices (rs=0.60, p <0.001). In addition, women with interstitial cystitis/bladder pain syndrome were more likely to have shortened pelvic floor muscles (80%, 12 vs 13.3%, 2, p <0.01). Women with shortened pelvic floor muscles demonstrated significantly higher resting root mean squared ratio compared to those with normal pelvic floor muscle length (0.155±0.046 vs 0.107±0.040, p=0.0058). Intravaginal high-density surface electromyography offers an objective and quantitative strategy to noninvasively assess pelvic floor muscle dysfunction in women with interstitial cystitis/bladder pain syndrome. Abundant spatiotemporal muscle activity information captured by high-density surface electromyography allows for mapping innervation zone distributions for major pelvic floor muscles.

Defecation versus pre- and post-defecation Valsalva maneuvers for dynamic MR assessment of pelvic floor dysfunction.

To compare prevalence and severity of multi-compartment pelvic floor dysfunction between supine magnetic resonance defecography with defecation (MRD) and supine dynamic MRI during Valsalva, both with and withoutrectal distention. This was an IRB-approved, HIPAA-compliant retrospective review of consecutive patients referred for MR Defecography. MRD protocol included imaging at rest, during pre-defecation Valsalva (Pre-DV), defecation (Def), and post-defecation Valsalva (Post-DV). The Post-DV images were performed after complete evacuation either during the defecation acquisition or, in cases where patient was unable to defecate during the examination, in a conventional toilet. Size of cystocele, vaginal prolapse, anorectal (AR) descent, and enterocele were measured on all acquisitions relative to the pubococcygeal line. Rectocele size was recorded in anteroposterior dimension. The presence or absence of rectal intussusception (RI) was documented. The prevalence, absolute size, and grades of prolapse, rectocele, and RI were compared between the acquisitions using pair-wise ANOVA, Friedman, Dunn pair-wise, and Cochran-Mantel-Haenszel tests. 30 patients were included in the final analysis. Higher prevalence of cystocele, vaginal prolapse, enterocele,AR descent grade 2 or higher, rectocele grade 2 or higher, and RI were seen on Def compared to Post-DV and Pre-DV. Cystocele, vaginal prolapse, enterocele, AR descent, and rectocele sizes were significantlylarger on Def compared to Post-DV by 0.7-1.95cm (p ≤ 0.007). Prolapse in all compartments and rectocele size were significantly larger on Def compared to Pre-DV (p < 0.0001). Cystocele, vaginal prolapse, and enterocele sizes were significantly larger on Post-DV compared to Pre-DV (p < 0.0001). There were significant differences in grading of all types of prolapse and rectocele between the various acquisitions of MRD (p < 0.0001). Cystocele, AR descent, and rectocele grades were significantlyhigher on Def compared to Post-DV (p range ≤ 0.0002). Grading of all types of prolapse and rectocele was significantlyhigher on Def compared to Pre-DV (p < 0.0001). Cystocele, vaginal prolapse, and enterocele grades were all significantly higher on Post-DV compared to Pre-DV (p ≤ 0.0007). Defecation images during supine MRD elicit higher prevalence and size of prolapse of all pelvic compartments in comparison to both pre- and post-defecation Valsalva images. Post-defecation Valsalva images show largersize of anterior and middle compartment prolapse than pre-defecation Valsalva images. Functional evaluation of pelvic floor dysfunction with MRI should include image acquisition during defecation. If Valsalva images are acquired, these should be performed after the defecation acquisition and without rectal distention.

Role of Dynamic MRI in Assessment of Pelvic Floor Dysfunction in Females

Introduction: Pelvic floor dysfunction is a major medical and social problem. Dynamic MR imaging of the pelvic floor is an excellent tool for assessing functional disorders of the pelvic floor. Findings reported at dynamic MR imaging of the pelvic floor are valuable for selecting patients who are candidates for surgical treatment and for choosing the appropriate surgical approach. Aim of the work: To highlight the role of dynamic MRI as a non-invasive method in the assessment of pelvic floor dysfunction in females. Methods: Dynamic and static MRI were performed in 20 female patients complaining of pelvic organ prolapse and/or stress urinary incontinence or defecation disorder. Full history was taken and clinical examination performed and findings compared with MRI results. Results: Good concordance was found between dynamic MRI and clinical examination in all three compartments, it was 75% in the anterior compartment, 80% in the posterior compartment, 65% in enteroceles and 75.0% in the middle compartment. Conclusion: MR imaging provides excellent soft tissue contrast to ensure adequate diagnosis of the muscular and fascial defects responsible for pelvic floor dysfunction.

Total pelvic floor ultrasound for pelvic floor defaecatory dysfunction: a pictorial review.

Total pelvic floor ultrasound is used for the dynamic assessment of pelvic floor dysfunction and allows multicompartmental anatomical and functional assessment. Pelvic floor dysfunction includes defaecatory, urinary and sexual dysfunction, pelvic organ prolapse and pain. It is common, increasingly recognized and associated with increasing age and multiparity. Other options for assessment include defaecation proctography and defaecation MRI. Total pelvic floor ultrasound is a cheap, safe, imaging tool, which may be performed as a first-line investigation in outpatients. It allows dynamic assessment of the entire pelvic floor, essential for treatment planning for females who often have multiple diagnoses where treatment should address all aspects of dysfunction to yield optimal results. Transvaginal scanning using a rotating single crystal probe provides sagittal views of bladder neck support anteriorly. Posterior transvaginal ultrasound may reveal rectocoele, enterocoele or intussusception whilst bearing down. The vaginal probe is also used to acquire a 360° cross-sectional image to allow anatomical visualization of the pelvic floor and provides information regarding levator plate integrity and pelvic organ alignment. Dynamic transperineal ultrasound using a conventional curved array probe provides a global view of the anterior, middle and posterior compartments and may show cystocoele, enterocoele, sigmoidocoele or rectocoele. This pictorial review provides an atlas of normal and pathological images required for global pelvic floor assessment in females presenting with defaecatory dysfunction. Total pelvic floor ultrasound may be used with complementary endoanal ultrasound to assess the sphincter complex, but this is beyond the scope of this review.

The investigation and treatment of female pelvic floor dysfunction.

25% of all women report involuntary loss of urine, and 7% may require treatment. This review is based on a selection of pertinent literature, including guidelines and Cochrane reviews. The assessment of pelvic floor dysfunction in women begins with a basic evaluation that is followed by special diagnostic tests if indicated. The physician taking the clinical history should inquire about the patient's behavior, personality, social and other stressors, and eating and drinking habits, as well as any mental disorders that may be present, including anxiety disorders, depression, somatization disorders, and disorders of adaptation. Conservative treatment consists mainly of lifestyle changes, physiotherapy, and medication. Stress incontinence is most commonly treated with pelvic floor exercises, with a documented success rate of 56.1% vs. 6% without such treatment (relative risk 8.38, 95% confidence interval 3.67-19.07). If incontinence persists, surgery may be indicated ( implantation of suburethral tension-free slings, or colposuspension). Feedback and biofeedback training can be used to treat an overactive bladder. If these techniques and drug therapy are unsuccessful, botulinum toxin injections can be considered. Well-validated treatments for pelvic floor dysfunction are available. Psychosomatic factors must be taken into account and can have a major effect on treatment outcomes.

Role of perineal ultrasound in the evaluation of urinary stress incontinence and pelvic organ prolapse: A systematic review

A review of the international literature on urogynecology was performed to focus on the actual role of perineal ultrasound. It is an increasingly used tool for the assessment of pelvic floor dysfunction and incontinence. In recent years ultrasound studies have predominated but there is little information on normal values and confusion on methodology and measurements. The aim of this study is to report the data available in the Literature about ultrasound as investigational evaluation helpful in diagnosing of urinary incontinence and urethral hypermobility, to document pelvic floor anatomy and to assess anatomic and functional changes after surgery. A MEDLINE search was conducted using combinations of heading terms: perineal, ultrasound, pelvic floor, urinary incontinence, pelvic organ prolapse. Ultrasound has become an indispensable diagnostic procedure in urogynecology. Perineal, introital, and endoanal ultrasound are the most recommended techniques and the results comprise qualitative and quantitative findings. These are important for determining the localization of the bladder neck and vesico-urethral junction and also for pre- and postoperative comparisons, and moreover for clinical applications and scientific investigations. There are as yet little data and there is a need to find in the near future more standard and objective parameters for the diagnosis of urinary incontinence. They will be obtained by means of more accurate analysis and comparison of the parameters, leading to a more clinically useful diagnostic test and assuring reliable and reproducible results.

Magnetic resonance imaging of the pelvic floor.

Magnetic resonance imaging is a novel noninvasive imaging modality for the assessment of pelvic floor dysfunction. It relies on static sequences with a high spatial resolution to study muscle morphology (levator ani) and fast imaging dynamic sequences during contraction, rest, and straining. Prolapse of the various pelvic compartments is detected with respect to organ position relative to the pubococcygeal line during dynamic phases. Compared with clinical examination, its input appears to be especially invaluable in the posterior compartments (peritoneal and digestive) and to assess complex prolapses involving more than one pelvic compartment. It is also useful for understanding postsurgical recurrences.

Clinical assessment of pelvic floor dysfunction in multiple sclerosis: urodynamic and neurological correlates.

We present a study on the clinical assessment of pelvic floor dysfunction in 30 female patients with proven multiple sclerosis (MS). A scoring system for pelvic floor muscle testing by digital vaginal palpation is proposed. The concept of pelvic floor spasticity in MS is introduced. The relationship of our findings with the neurological findings and urodynamic data is presented. Pelvic floor spasticity correlates well with the presence of detrusor-external sphincter dyssynergia and with more severe spinal cord disease.
