The Use of an Intra-Vaginal Pressure Sensor Device To Evaluate Changes in Intra-Vaginal Pressure Profiles Pre and Post Pelvic Organ Prolapse Surgery
2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019Co-Authors: Laura Pedofsky, David Budgett, Poul M. F. Nielsen, Jackie Smallridge, Lynsey Hayward, Jennifer KrugerAbstract:Outcomes on pelvic Floor Function after pelvic Floor surgery are difficult to quantify. Urinary incontinence affects 25% of women, with 12% of these women requiring surgical intervention to relieve symptoms. However, quantitative measurement of pelvic Floor Function following surgery is not currently available. This work considers the use of an intra-vaginal pressure sensor array to measure the vaginal pressure profile as a means to quantify surgical outcomes. An observational cohort study is underway to evaluate changes in vaginal pressure profiles pre and post pelvic organ prolapse surgery.

Pelvic Floor Function in nulliparous women using three-dimensional ultrasound and magnetic resonance imaging.
Obstetrics and gynecology, 2008Co-Authors: Jennifer Kruger, Bernadette Murphy, Sw Heap, Hans Peter DietzAbstract:OBJECTIVE: To compare biometric measures of pelvic Floor Function obtained using three-dimensional (3D) ultrasound and magnetic resonance imaging (MRI) in a group of nulliparous asymptomatic young women. METHODS: Twenty-seven asymptomatic nulliparous volunteers were assessed prospectively, using translabial 3D ultrasound and multiplanar 3D MRI. Levator hiatal dimensions were measured in the axial plane in both modalities. All participants were imaged supine, after voiding with data acquired at rest, on maximum Valsalva and maximum pelvic Floor contraction. Interobserver variability was determined for both methods. Normally distributed continuous ultrasound data were compared with equivalent MRI parameters, and intraclass correlation coefficients were used to estimate correlation between the two methods. Bland-Altman analysis was also used to estimate agreement between methods. RESULTS: Interobserver repeatability was fair to excellent for all parameters measured with both methods. Moderate-to-substantial agreement between methods was shown for all tested parameters (intraclass correlation coefficients 0.587-0.783). There was a systematic but nonsignificant difference between methods, in that measurements on Valsalva tended to be larger for MRI, and the poorest agreement (intraclass correlation coefficient 0.587) was found for hiatal area on Valsalva. CONCLUSION: Agreement between the two methods was moderate to substantial for all parameters except for hiatal area on Valsalva. Magnetic resonance imaging yielded higher area measurements on Valsalva, which may indicate difficulties in identifying the plane of minimal dimensions due to poorer temporal resolution compared with ultrasound imaging.

Pelvic Floor Function in elite nulliparous athletes.
Ultrasound in obstetrics & gynecology : the official journal of the International Society of Ultrasound in Obstetrics and Gynecology, 2007Co-Authors: Jennifer Kruger, Hans Peter Dietz, Bernadette MurphyAbstract:Objective There is preliminary evidence linking longterm participation in high-impact exercise with poor performance in labor and increased incidence of stress urinary incontinence, which may be due to altered pelvic Floor Function. Recent work has shown that HIFIT (high-impact, frequent intense training) athletes have an increased cross-sectional area of the levator ani muscle group as visualized using magnetic resonance imaging (MRI). The aim of this study was to further characterize pelvic Floor muscle Function and pelvic organ descent in a nulliparous athletic population and compare it with nonathletic controls matched for age and body mass index, using three-dimensional/four-dimensional (3D/4D) pelvic Floor ultrasound imaging. Methods In this prospective comparative study translabial ultrasound imaging was used to assess pelvic Floor anatomy and Function in 46 nulliparous female volunteers (aged 19‐39 years), 24 HIFIT and 22 controls. Twodimensional (2D) and 3D translabial ultrasonography was performed on all subjects, after voiding and in the supine position. Descent of the pelvic organs was assessed on maximum Valsalva maneuver, whilst volume datasets were acquired at rest, during pelvic Floor muscle contraction and during a Valsalva maneuver. Participants performed each maneuver at least three times and the most effective was used for evaluation. Results HIFITathletes showeda higher mean diameter of the pubovisceral muscle (0.96 cm vs. 0.70 cm, P < 0.01), greater bladder neck descent (22.7 mm vs. 15.1 mm, P = 0.03) and a larger hiatal area on Valsalva maneuver (21.53 vs. 14.91 cm 2 , P = 0.013) compared with the control group. There were no significant differences in hiatal area at rest or on maximal voluntary contraction between the two groups. Conclusion HIFIT athletes show significant differences in several of the measured parameters for both Function and anatomy of the pelvic Floor. Further research into the impact of this altered Function on childbirth and continence mechanisms is needed. Copyright ! 2007 ISUOG. Published by John Wiley & Sons, Ltd.

Hormonal contraception and pelvic Floor Function: a systematic review
International Urogynecology Journal, 2016Co-Authors: Rita Champaneria, Ruben Mamprin D’andrea, Pallavi LattheAbstract:Introduction and hypothesis Hormonal contraceptive use is common practice worldwide. Although the effects of hormone treatments in the pelvic region are well established, there is no clear evidence regarding their effects on incontinence, bladder, bowel, vaginal and sexual symptoms in premenopausal women. We hypothesized that hormonal contraceptives affect pelvic Floor Function. We therefore performed a comprehensive systematic review of published studies to determine the influence of hormonal contraception on pelvic Floor Functions. Methods Electronic literature databases were searched from database inception to March 2015. Keywords and medical subject headings searched for included terms and word variations for ‘contraception’, and ‘bowel’, ‘vaginal’, ‘sexual’ and ‘urinary’ symptoms. Studies were eligible if they looked at these symptoms in women taking hormonal contraception. Two reviewers independently screened studies for inclusion, and extracted data on study characteristics, quality and results. Data were combined where possible. Results Of the 429 citations identified, 13 studies were included in the review. Data were meta-analysed where possible and presented as prevalence. The results indicate statistically significant links between interstitial cystitis and oral contraceptive use at any point (ever) (OR 2.31, 95 % CI 1.03 – 5.16; p = 0.04) and vulvar vestibulitis and current oral contraceptive use (OR 2.10, 95 % CI 1.26 – 3.49; p = 0.004). The evidence is unclear in other areas. Conclusions Our results indicate that oral contraceptives may have an effect on pelvic Floor Function. They could increase the risk of painful bladder and vulvar vestibulitis, but their effect on dyspareunia is inconsistent. However, robustly collected prospective data to establish causal associations are needed.
