Pelvic floor dysfunction and obesity.

Obesity is a growing condition within the society and more patients, who have underlying obesity, are presenting with lower urinary tract symptoms (LUTS) and pelvic floor dysfunction (PFD). The effect of obesity on general health has been well documented, and its impact on the cardiovascular, endocrine, and musculoskeletal systems has been extensively studied. There is now a growing body of evidence on the effects of obesity on the female urogenital system. It seems to influence the prevalence, presentation, assessment, management, and outcome of various types of LUTS and PFD. A holistic approach is needed to assess and manage these patients. A clear understanding of the functions of the pelvic floor and the way it can be affected by obesity is essential in providing holistic care to this group. A frank discussion about patient weight is required in the clinics handling PFD. A multimodal approach to weight loss would help improve PFD symptoms and progression. Patients with obesity should still be offered standard treatment options for all PFDs and should not be forced to lose weight as a prerequisite before starting treatment. However, they should also be made aware of the impediments that being overweight adds to their care and their expectations should be managed accordingly.

Analysis of the status quo of pelvic floor muscle and the effect of pelvic floor muscle training in second pregnant women.

OBJECTIVE: This study aims to investigate the current situation of pelvic floor muscle (PFM) in the second trimester postpartum 42 days by detecting the electrophysiological indexes of PFM on pelvic floor rehabilitation after 2 months. METHODS: In total, 198 cases of second child puerpera were selected, who were delivered in our hospital between June 1, 2020, and December 10, 2020, and underwent outpatient reexamination 42 days after delivery. RESULTS: Except for the rest post-baseline stage values, the pelvic floor surface electromyography evaluation values significantly differed from each other at the considered time points in group A, P < .05; on day 72 in group B, no obvious improvement in the evaluation values was observed as than those on day 42 (P > .05) except for the endurance contractions stage values. However, on day 102, all values were markedly different at each considered time point (P < .05). On day 102 postpartum, the evaluation values of group A in the rest pre-baseline stage, the time before and after peak of phasic (flick) contractions stage, and the endurance contractions stage were significantly improved to those in group B with all P < .05. On day 42 after parturition, each index of the tonic contractions stage was higher after spontaneous labor than that after cesarean; the differences were all significant, P < .05, but on day 102 postpartum, all of the values exhibited no difference between the 2 modes. In only the phasic (flick) contractions stage at 42th, were the values of younger mothers obviously higher, P = .025; the other stage values for different ages of women during different time periods were not statistically significant, P > .05. CONCLUSIONS: In the short term, the effect of biofeedback plus electrical stimulation on the PFM function in second pregnant women was better than that of the Kegel exercise, but with time, there was no significant difference between the 2 training methods on the recovery of the PFM.

Acupoint injection combined with pelvic floor rehabilitation in the treatment of postpartum pelvic floor disorders: A protocol of randomized controlled trial.

BACKGROUND: Female pelvic floor dysfunction is one of the common chronic diseases affecting women's physical and mental health. Pregnancy and delivery are one of the main causes. Pelvic floor rehabilitation is a common method for the treatment of postpartum pelvic floor dysfunction, but it has some defects. Acupoint injection has advantages in the treatment of postpartum pelvic floor dysfunction, but there is a lack of standard clinical research to verify it. Therefore, the purpose of this randomized controlled trial is to evaluate the efficacy and safety of acupoint injection combined with pelvic floor rehabilitation in the treatment of postpartum pelvic floor disorders. METHODS: This is a prospective randomized controlled trial to study the efficacy and safety of acupoints injection combined with pelvic floor rehabilitation. And it is approved by the Ethics Committee of Clinical Research of our hospital. Patients were randomly divided into observation group (acupoint injection combined with pelvic floor rehabilitation group) or control group (pelvic floor rehabilitation group alone). The patients were followed up for 8 weeks after 12 weeks of treatment. The observation indexes included: pelvic organ prolapse degree, pelvic floor muscle strength, urinary incontinence score, adverse reactions, among others. Data were analyzed using the statistical software package SPSS version 18.0. CONCLUSIONS: This study will evaluate the efficacy and safety of acupoint injection combined with pelvic floor rehabilitation in the treatment of postpartum pelvic floor dysfunction, and provide reliable reference for the clinical application of this project.

The Effect of Pelvic Floor Muscle Interventions on Pelvic Floor Dysfunction After Gynecological Cancer Treatment: A Systematic Review.

OBJECTIVE: The aim of this systematic review was to identify, evaluate, and synthesize the evidence from studies that have investigated the effect of nonsurgical, nonpharmacological, pelvic floor muscle interventions on any type of pelvic floor dysfunction or health-related quality of life in patients after any type of treatment for gynecological cancer. METHODS: Six electronic databases (Cochrane Library 2018, CINAHL 1982-2018, MEDLINE 1950-2018, EMBASE 1980-2018, PsycINFO 1806-2018, and EMCARE 1995-2018) were systematically searched in June 2018. Reference lists of identified articles were hand searched. Randomized controlled trials (RCTs), cohort studies, and case series were included if they investigated the effects of conservative treatments, including pelvic floor muscle training or dilator training, on bladder, bowel, or sexual function in patients who had received treatment for gynecological cancer. Risk of bias was assessed using the Physiotherapy Evidence Database scale for RCTs and the Newcastle-Ottawa scale for cohort studies. RESULTS: Five RCTs and 2 retrospective cohort studies were included (n = 886). The results provided moderate-level evidence that pelvic floor muscle training with counseling and yoga or core exercises were beneficial for sexual function (standardized mean difference = -0.96, 95% CI = -1.22 to -0.70, I2 = 0%) and health-related quality of life (standardized mean difference = 0.63, 95% CI = 0.38 to 0.88, I2 = 0%) in survivors of cervical cancer and very low-level evidence that dilator therapy reduced vaginal complications in survivors of cervical and uterine cancer (odds ratio = 0.37, 95% CI = 0.17 to 0.80, I2 = 54%). There were insufficient data for meta-analysis of bladder or bowel function. CONCLUSION: Conservative pelvic floor muscle interventions may be beneficial for improving sexual function and health-related quality of life in survivors of gynecological cancer. Given the levels of evidence reported in this review, further high-quality studies are needed, especially to investigate effects on bladder and bowel function. IMPACT: This review provides moderate-level evidence for the role of pelvic floor rehabilitation to improve health outcomes in the gynecological cancer survivorship journey. Clinicians and health service providers should consider how to provide cancer survivors the opportunity to participate in supervised pelvic floor rehabilitation programs.

Individualized pelvic physical therapy for the treatment of post-prostatectomy stress urinary incontinence and pelvic pain.

BACKGROUND: The rehabilitation of post-prostatectomy urinary incontinence has traditionally focused on pelvic floor strengthening exercise. The goal of this study was to determine whether an individualized pelvic physical therapy (PT) program aimed at normalizing both underactive and overactive pelvic floor dysfunction (PFD) can result in improvement in post-prostatectomy stress urinary incontinence (SUI) and pelvic pain. METHODS: A retrospective chart review of 136 patients with post-prostatectomy SUI and treated with pelvic PT. Patients were identified as having either underactive, overactive, or mixed-type PFD and treated accordingly with a tailored program to normalize pelvic floor function. Outcomes including decrease in SUI as measured in pad usage per day and pain rated on the numeric pain rating scale. RESULTS: Twenty five patients were found to have underactive PFD and were treated with strengthening. Thirteen patients had overactive PFD and were treated with relaxation training. Ninety eight patients had mixed-type PFD and were treated with a combination of relaxation training followed by strengthening. Patients demonstrated statistically significant decrease in pad usage per day (p < 0.001), decreased pelvic pain (p < 0.001), and increased pelvic floor strength (p = 0.049), even in patients who received predominantly pelvic floor relaxation training to normalize pelvic floor overactivity. CONCLUSIONS: A majority of post-prostatectomy men with SUI have pelvic floor overactivity in addition to pelvic floor underactivity. An individualized pelvic PT program aimed at normalizing pelvic floor function (as opposed to a pure Kegel strengthening program) can be helpful in reducing SUI and pelvic pain.

SLK Triple Therapy Improves Maternal and Fetal Status and Promotes Postpartum Pelvic Floor Function in Chinese Primiparous Women.

BACKGROUND During pregnancy, appropriate physical activity plays critical roles in maternal and fetal health. This study investigated the effects of Sophrology childbirth-Kegel-Lamaze respiratory training (SLK triple therapy) on maternal and newborn health, pelvic floor function, and quality of life. MATERIAL AND METHODS Single-pregnant primiparous women involved in this study were divided into the control group (n=120) and the SLK triple therapy group (n=120). SLK triple therapy was taught to and practiced by the women in the SLK triple therapy group. Data on delivery mode (natural delivery or cesarean section), postpartum complications (postpartum urinary incontinence, postpartum hemorrhage), and birth process were recorded. Apgar scores and body weight of newborns were evaluated. Pelvic floor function, postpartum emotion, and sexual functions were assessed. RESULTS Women in the SLK triple therapy group had significantly better natural delivery rate compared to the control group (p<0.05). SLK triple therapy significantly decreased the postpartum urinary incontinence rate and reduced the postpartum hemorrhage rate compared to the control group (p<0.05). Birth process and postpartum hemorrhage volume in the SLK triple therapy group were also significantly lower compared to the control group (p<0.05). Apgar scores were significantly lower and body weights were significantly higher in the SLK triple therapy group compared to the control group (p<0.05). SLK triple therapy significantly improved pelvic floor function compared to the control group (p<0.05). SLK triple therapy significantly decreased SDS scores and enhanced FSFI scores compared to the control group (p<0.05). CONCLUSIONS SLK triple therapy improved maternal and fetal health by improving pregnancy outcomes, promoting postpartum pelvic floor function, reducing the incidence of depression, and enhancing sexual function. Therefore, SLK triple therapy has great utility in treating primiparous women.

Empty pelvis syndrome: the use of breast prosthesis in the prevention of complications.

AIM: Empty pelvis syndrome and radiation-induced bowel injury are two major clinical issues resulting from the pelvic dead space after pelvic exenteration (PE). In order to avoid these complications, different methods of pelvic floor reconstruction have been proposed. We report our experience on the use of breast prosthesis. METHOD: Fifty-three patients who underwent PE and three who underwent palliative surgery with silicone breast prosthesis placement were included. RESULTS: Forty-seven posterior PE, six total PE and three palliative procedures were identified. Sphincter preservation was feasible in 34 patients (62.3%). There were no deaths. Overall morbidity was 37.5%. There were no complications such as sepsis or obstruction related to the prosthesis. Adjuvant radiotherapy was delivered in 16 cases (30.1%) without any side-effects. Reconstruction of intestinal continuity was possible in 12 patients (36.3%) with sphincter preservation and the prosthesis allowed a prompt identification of the rectal stump. CONCLUSION: Breast prosthesis placement is a simple and safe method to minimize complications resulting from empty pelvis syndrome and can be adopted to exclude bowel loops from the radiation field. Reconstruction of intestinal continuity after resection is also simplified.

Pilot in vitro and in vivo study on a mouse model to evaluate the safety of transcutaneous low-frequency electrical nerve stimulation on cervical cancer patients.

INTRODUCTION AND HYPOTHESIS: To clarify whether the pulse electrical field (PEF) caused by transcutaneous low-frequency nerve electrical stimulation (TENS) enhances the proliferation of cervical cancer cells, leading to recurrence and metastasis, and the effect of such a PEF on a cervical cancer mouse model. METHODS: 1. In vitro experiment: SiHa cervical cancer cells treated with one session of microsecond PEFs for 30 min were divided into four groups: three experimental groups and the control group. Cell proliferation and migration were determined by CCK-8 proliferation and Transwell chamber Matrigel migration assay. 2. In vivo experiment: A mouse cancer model was established by subcutaneous implantation of SiHa cells that were then were randomly divided into the TENS group and control group. The former group received one session of TENS treatment and the control group received a sham pulse. The growth trend and tumor volume of each group were compared 28 days after PEF treatment. The proliferation and apoptosis of the tumor were determined by an immunohistochemical method. RESULTS: (1) The CCK-8 proliferation assay and cell migration ability showed no difference after PEF stimulation treatment (F = 2.478, P = 0.136 > 0.05 and F = 0.364, P = 0.779). (2) Tumor growth, size and weight showed no significant difference between the two groups. (3) Expression of VEGF, CD34, caspase-3 and Ki-67 in the tumor tissue showed no significant difference between the two groups. CONCLUSIONS: In vitro and in vivo experiments (mice) showed that the PEF created by TENS had no effect on the proliferation and migration of SiHa cervical cancer cells and also had no effect on the tumor growth, tumor cell apoptosis and proliferation.

Effect of different delivery modes on the short-term strength of the pelvic floor muscle in Chinese primipara.

BACKGROUND: To investigate the effect of different delivery modes and related obstetric factors on the short-term strength of the pelvic floor muscle after delivery in Chinese primipara. METHODS: A total of 4769 healthy Chinese primiparas at postpartum 6-8 weeks were interviewed. According to the difference of delivery mode, the selected primiparas were divided into 2 groups, including cesarean delivery group containing 2020 and vaginal delivery group containing 2749. All the vaginal deliveries were further divided into 3 groups, including episiotomy group containing 2279, perineal laceration group containing 398, and forceps assisted group containing72. The scales of their pelvic floor muscle (PFM) strengths were examined by specially trained personnel using digital palpation (Modified Oxford scale:0-5 grade). According to participants' willingness, if the PFM strength was weak (0 or 1 grade), at-home PFM training would be recommended and an electrical stimulation combined with biofeedback therapy would be conducted for them in hospital. Twelve weeks after delivery, the PFM strength would be measured again. For statistical analysis, t-test, one-way variance analysis, Chi-square analysis, Kruskal-Wallis test H, Mann-Whitney U test and Wilcoxon test were carried out. RESULTS: The PFM strength in cesarean delivery group was higher than in vaginal delivery group (p < 0.05). Among 3 vaginal delivery groups, the PFM strength in perineal laceration group was the highest (p < 0.05); however, there was no difference in PFM strength between episiotomy group and forceps assisted group (p>0.05). After accepting PFM training at home and therapy in hospital, 305 women showed increased PFM strength (p < 0.05). CONCLUSIONS: Vaginal delivery is an independent risk factor causing the damage of PFM, and episiotomy may cause injury of PFM. Through PFM training at home and therapy in hospital, those damage will resume as soon as possible in the short-time period after delivery.

A Review of Phytoestrogens and Their Association With Pelvic Floor Conditions.

INTRODUCTION: Urinary incontinence, pelvic organ prolapse, and fecal incontinence are pelvic floor disorders (PFDs) disproportionately experienced by postmenopausal women. Limited data exist suggesting that phytoestrogens may have an impact on the pathophysiology and symptom of PFDs. PURPOSE OF REVIEW: The aim of the study was to review the current literature addressing the role of phytoestrogens on PFDs, including the pathophysiology, symptom, treatment, and possible prevention. FINDINGS: Qualifying literature spans from 2003 to 2017 and included 14 studies ranging from in vitro, animal, and observational studies to randomized clinical trials. SUMMARY: Although the literature is limited, most studies on phytoestrogens and PFDs support associations with pathophysiologic mechanisms, symptoms, and treatment for urinary incontinence and pelvic organ prolapse, but not fecal incontinence. Less is known regarding the prevention of PFDs with phytoestrogen intake over time. Overall, the potential influence of phytoestrogens on PFDs is not well understood, and more research is needed.

ICS Educational Module: Electromyography in the assessment and therapy of lower urinary tract dysfunction in adults.

AIM: To present the teaching module "Electromyography in the assessment and therapy of lower urinary tract dysfunction in adults." This teaching module embodies a presentation, in combination with this manuscript. This manuscript serves as a scientific background review; the evidence base made available on ICS website to summarize current knowledge and recommendations. METHODS: This review has been prepared by a Working Group of The ICS Urodynamics Committee. The methodology used included comprehensive literature review, consensus formation by the members of the Working Group, and review by members of the ICS Urodynamics Committee core panel. RESULTS: Electromyography (EMG) is a method to record spontaneous or artificially induced electrical activity of the nerve-muscle unit or to test nerve conductivity. EMG of the anal sphincter using surface electrode is most widely used screening technique to detect detrusor-sphincter dyssynergia in urology. It is non-invasive and easy to perform. EMG methods using needle electrodes are reserved for diagnostics in well selected group of mainly neurogenic patients. These methods require expertise in the field of general EMG and are usually performed by neurologist and neuro-physiologist. The evidence in many aspects of use of EMG in urology remains sparse. CONCLUSIONS: Currently EMG methods rarely play a decision making role in selecting proper treatment of lower urinary tract dysfunction. With the current efforts to improve phenotyping of these patients in order to provide individualized treatment, the role of EMG could increase.

Short-term outcome of percutaneous tibial nerve stimulation for low anterior resection syndrome: results of a pilot study.

AIM: Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive procedure which has been demonstrated to be effective in faecal/urinary incontinence but has never been tested in low anterior resection syndrome (LARS). The severity of LARS may be evaluated by the LARS score, but rectal cancer treatments may also affect urinary and sexual function, which are not explored by the LARS score. The Three Axial Perineal Evaluation (TAPE) score is a new validated index addressing the overall pelvic floor functions. This study aims to assess the efficacy of PTNS in LARS patients and to evaluate the results by the LARS and TAPE scores. METHODS: Twenty-one patients operated on for rectal cancer between 2009 and 2014 complaining of LARS underwent PTNS (12 sessions of 30 min each). Six patients reported urinary incontinence and all except two (men) were sexually inactive. The LARS score and the TAPE score questionnaires were administered at baseline and after 6 months of follow-up. RESULTS: At 6 months' follow-up, nine patients reported a significant improvement of faecal incontinence and 3/6 an improvement of urinary incontinence after PTNS. Median LARS score significantly decreased from 32 to 27 (P = 0.009), while the median TAPE score improved significantly from 55 to 58 (P = 0.004). CONCLUSIONS: PTNS may be a further option in the treatment of selected patients with LARS and in addition may improve associated urinary incontinence. The severity of LARS can be detected by the LARS score; however, the adoption of the TAPE score is preferred in the case of concomitant urinary and/or sexual problems not explored by the LARS score.

Ultrasound-based motor control training for the pelvic floor pre- and post-prostatectomy: Scoring reliability and skill acquisition.

AIM: This study documents a protocol designed to evaluate pelvic floor motor control in men with prostate cancer. It also aims to evaluate the reliability of therapists in rating motor control of pelvic floor muscles (PFMs) using real time ultrasound imaging (RUSI) video clips. We further determine predictors of acquiring motor control. METHODS: Ninety-one men diagnosed with prostate cancer attending a physiotherapy clinic for pelvic floor exercises were taught detailed pelvic floor motor control exercises by a physiotherapist using trans-abdominal RUSI for biofeedback. A new protocol to rate motor control skill acquisition was developed. Three independent physiotherapists assessed motor control skill attainment by viewing RUSI videos of the contractions. Inter-rater reliability was evaluated using intra-class correlation coefficients. Logistic regression analysis was conducted to identify predictors of successful skill attainment. Acquisition of the skill was compared between pre- and post-operative participants using an independent-group t-test. RESULTS: There was good reliability for rating the RUSI video clips (ICC 0.73 (95%CI 0.59-0.82)) for experienced therapists. Having low BMI and being seen pre-operatively predicted motor skill attainment, accounting for 46.3% of the variance. Significantly more patients trained pre-operatively acquired the skill of pelvic floor control compared with patients initially seen post-operatively (OR 11.87, 95%CI 1.4 to 99.5, p = 0.02). CONCLUSIONS: A new protocol to evaluate attainment of pelvic floor control in men with prostate cancer can be assessed reliably from RUSI images, and is most effectively delivered pre-operatively.

Do Obstetrical Providers, Counsel Women About Postpartum Pelvic Floor Dysfunction?

OBJECTIVE: To assess prenatal counseling practices of obstetrics providers related to postpartum pelvic floor dysfunction at centers with integrated urogynecology services. STUDY DESIGN: A cross-sectional survey was distributed to obstetrical providers through urogynecology colleagues. The survey included questions about level of training as well as counseling practices related to common postpartum pelvic floor symptoms. All statistical tests were two-sided, and p values < 0.05 were considered statistically significant. RESULTS: A total of 192 surveys were received; 19 respondents did not perform their own prenatal counseling and were excluded. Among the remaining 173 respondents, 94 (56.3%) of those who answered the question reported never discussing postpartum urinary incontinence, and 73.7% reported never discussing postpartum fecal incontinence during prenatal counseling. Obstetrics and gynecology residents were significantly less likely than attending physicians to report discussing various pelvic floor dysfunction topics in prenatal counseling. Among those who reported not counseling women regarding pelvic floor dysfunction, the most common reason cited was lack of time (39.9%) followed by lack of sufficient information (30.1%). CONCLUSION: Prenatal counseling of pelvic floor dysfunction risk is lacking at all levels of obstetrical training. Limitations of time and information are the obstacles most often cited by providers.

[Significance of conservative treatment for faecal incontinence]. / Stellenwert der konservativen Therapie bei Stuhlinkontinenz.

Based on a variety of aetiological factors and combined disorders in faecal incontinence, a conservative treatment option as the primary treatment can be recommended. Conservative treatment includes medical therapy influencing stool consistency and stool passage, pelvic floor exercises and biofeedback as well as local treatment options. However, defining the role of conservative treatment concepts related to success or failure remains a challenging task. The lack of evidence derived from studies is related to a variety of reasons including inclusion criteria, patient selection, treatment standardisation, and the principal difficulty to objectively define functional success.

[Functionality of pelvic floor in patients after vaginal and abdominal hysterectomy, valuation by EMG-Biofeedback according to Perfect Scheme]. / Hodnotenie funkcného stavu panvového dna metódou EMG-Biofeedback podl'a Perfect schémy u pacientiek po abdominálnej a vaginálnej hysterektómii.

OBJECTIVE: Our research deals with the efficiency of rehabilitation in patients after vaginal and abdominal hysterectomy. The activation of pelvic floor muscles has been evaluated and comparison of individual parameters according has been carried out. Also the occurrence of incontinence has been assessed. Subjects consisted of 66 women, out of which there were 21 women after vaginal hysterectomy and 45 women after abdominal hysterectomy. TYPE OF STUDY: Prospective experimental study. METHODS USE: EMG-biofeedback has been used for the evaluation of the functionality of pelvic floor according to Perfect Scheme. For the quantification of leaked urine one hour PW test has been used. REHABILITATION METHODS: We applied the individual exercise on strengthening and relaxation of pelvic floor muscles with the aid of repeated, selective voluntary contractions or relaxation of pelvic floor muscles conducted two times a week, with the duration time of 15 minutes. Group exercise on strengthening and relaxation of pelvic floor muscles conducted two times a week, with the duration time of 30 minutes. Biofeedback (EMG-Module) as a therapeutic method was applied. RESULTS: In patients after vaginal hysterectomy there was a higher occurrence of incontinence than in women after abdominal hysterectomy. In both groups a significant increase in pelvic floor muscle strength has been achieved after the therapy. In both of these groups there was no statistically significant relaxation of m. rectus abdominis after the therapy. The patients after abdominal hysterectomy had more statistically significant relaxed abdomen muscles before treatment than patients after vaginal hysterectomy. It means, that performed exercise in the right manner, with reduction of intra abdominal pressure. We suppose that this phenomenon may be related to the higher percentage of occurrence of incontinence in patients after vaginal hysterectomy.
