Efeito do tônus do corpo perineal nas disfunçõessexuais em mulheres jovens nulíparas / Effect of perineal body tone on sexual dysfunctionsin young nulliparous women

Objetivo: avaliar o tônus do corpo perineal em mulheres jovens nulíparas e correlacionar com as funções sexuais e a presença de disfunção sexual. Método: foi realizado um estudo descritivo, observacional, transversal utilizando uma amostra de conveniência incluindo mulheres adultas jovens nulíparas. A avaliação das participantes consistiu na aplicação dos questionários socioclínico, Pelvic Organ Prolaps / Urinary Incontinence Sexual Questionnaire (PISQ-12), Female Sexual Function Index (FSFI) e exame físico do tônus do corpo perineal. Os dados foram analisados pelo programa Statistical Package for the Social Sciences (SPSS®), versão 23, adotando um nível de significância de 5%. Resultados: participaram 77 mulheres jovens nulíparas (21,68 ± 2,94 anos), destas 77, 92% apresentavam vida sexual ativa e 66,03% tônus normal do corpo perineal. Dentre as alterações tônicas, o aumento do tônus predominou (33,76%). Houve alta prevalência de disfunção sexual (87,01%) pelo FSFI (23,38 ± 7,21) com maior queixa de dispareunia. Mulheres com tônus aumentado apresentaram maior disfunção sexual em relação a desejo e estímulo subjetivo (p=0,04), à excitação (p=0,01), satisfação (p=0,04) e dor ou a desconforto (p=0,03). Houve correlação inversa entre a presença de aumento do tônus e os domínios FSFI desejo e estímulo subjetivo (R= - 0,56) e excitação (R= - 0,34) e correlação direta para dor ou desconforto (R= 0,30). Conclusão: o aumento do tônus do corpo perineal piora a função sexual de mulheres jovens nulíparas.

Sexual Function Index (FSFI) and physical examination of the tone of the perineal body. The data were analyzed using the Statistical Package for the Social Sciences (SPSS®), version 23, adopting a significance level of 5%. Results: 77 young nulliparous women (21.68 ± 2.94 years) participated, of which 77, 92% had an active sexual life and 66.03% had normal tone of the perineal body. Among the tonic changes, increased tone predominated (33.76%). There was a high prevalence of sexual dysfunction (87.01%) according to the FSFI (23.38 ± 7.21) with greater complaints of dyspareunia. Women with increased tone had greater sexual dysfunction in relation to desire and subjective stimulation (p=0.04), excitement (p=0.01), satisfaction (p=0.04) and pain or discomfort (p=0.03). There was an inverse correlation between the presence of increased tone and the FSFI domains desire and subjective stimulus (R= - 0.56) and excitement (R= - 0.34) and a direct correlation for pain or discomfort (R= 0.30). Conclusion: increased perineal body tone worsens sexual function in young nulliparous women.

Effects of pelvic floor muscle training versus hypopressive abdominal gymnastics (HAG) on stress urinary incontinence in climacteric women: randomized clinical trial / Efectos del entrenamiento muscular del suelo pélvico versus la gimnasia abdominal hipopresiva (GAH) sobre la incontinencia urinaria de esfuerzo en mujeres climatéricas: ensayo clínico aleatorizado / Efeitos do treinamento muscular do assoalho pélvico versus Ginástica Abdominal Hipopressiva (GAH) na incontinência urinária de esforço de mulheres climatéricas: ensaio clínico randomizado

ABSTRACT Pelvic floor muscle training (PFMT) is recommended as first-line treatment for stress urinary incontinence (SUI) in women (scientific evidence level 1). Currently, hypopressive abdominal gymnastics (HAG) has been used in clinical practice without evidence for this purpose. To verify the superiority of an experimental treatment in relation to a positive control (gold standard) for the treatment of SUI and PFM function in climacteric women. A non-inferiority clinical trial was conducted with 31 climacteric women with SUI who were sexually active. They were allocated into two groups: 16 in the PFMT group and 15 in the HAG group. Both groups received 26 sessions twice per week and individual care. All participants were assessed twice, at the beginning and at the end of interventions. The primary outcome was assessed using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and the secondary were given by PFM function assessed via bidigital palpation. The methods used to analyze the results were the two-way repeated measures analysis of variance (ANOVA), followed by the Tukey post-hoc test, when necessary. PFMT was better in improving SUI in the primary outcome (p=0.01). The groups showed no significant difference in force of contraction, time of sustained PFM, and fast and slow repetitions at the time of analysis. Regarding the symptoms of SUI, PFMT performed better than HAG.

RESUMEN El entrenamiento muscular del suelo pélvico (EMSP) se recomienda como tratamiento de primera línea para las pruebas de nivel 1 de incontinencia urinaria de esfuerzo (IUE). Actualmente, se utiliza la gimnasia abdominal hipopresiva (GAH) en la práctica clínica con este fin. Este estudio tuvo por objetivo comprobar la superioridad de un tratamiento experimental en comparación con el tratamiento de referencia para la IUE y la función del suelo pélvico en mujeres menopáusicas. Se realizó un ensayo clínico aleatorizado de no inferioridad con 31 mujeres climatéricas sexualmente activas y con IUE. Las participantes se distribuyeron en dos grupos: 16 se sometieron a EMSP y 15 a GAH. Ambos recibieron 26 sesiones, dos veces por semana, en sesiones individuales. Todas las voluntarias fueron evaluadas en dos momentos, al principio y al final de las intervenciones. El resultado primario se evaluó mediante el cuestionario ICIQ-SF, y el resultado secundario mediante la evaluación bidigital del suelo pélvico. Para el análisis estadístico se utilizó la prueba ANOVA de dos vías, seguida de la prueba posterior de Tukey cuando necesario. El EMSP tuvo un mejor resultado en la mejora de la IUE (p=0,01). No hubo diferencias entre los grupos en cuanto a la fuerza de contracción, el tiempo de mantenimiento y las repeticiones rápidas y lentas. En cuanto a la mejora de los síntomas de IUE, se concluyó que el EMSP es superior a la GAH.

RESUMO O treinamento dos músculos do assoalho pélvico (TMAP) é recomendado como primeira linha no tratamento do nível 1 de evidência da incontinência urinária de esforço (IUE). Atualmente, a Ginástica Abdominal Hipopressiva (GAH) tem sido utilizada na prática clínica com este propósito. Este estudo tem como objetivo verificar a superioridade de um tratamento experimental em relação ao tratamento padrão-ouro para IUE e função do assoalho pélvico em mulheres na menopausa. Foi conduzido um ensaio clínico randomizado de não inferioridade com 31 mulheres climatéricas, sexualmente ativas e com IUE. Elas foram alocadas em dois grupos, em que: 16 foram submetidas ao TMAP e 15 à GAH. Ambos receberam 26 sessões, duas vezes por semana, em atendimentos individuais. Todas as voluntárias foram avaliadas em dois momentos, no início e ao término das intervenções. O desfecho primário foi avaliado pelo Questionário (ICIQ-SF) e o secundário pela avaliação bidigital do assoalho pélvico. Para a análise estatística, foram utilizados o teste ANOVA de duas vias, seguido do pós-teste de Tukey, quando necessário. O TMAP foi superior na melhora da IUE (p=0.01). Não houve diferença entre os grupos em relação a força de contração, tempo de sustentação, repetições rápidas e lentas. Em relação à melhora dos sintomas de IUE, concluiu-se que o TMAP é superior a GAH.

Effects of Transcranial Direct Current Stimulation and Pelvic Floor Muscle Training in Women: protocol for a controlled, randomized, double-blind clinical trial / Efectos de la estimulación transcraneal por corriente directa y del entrenamiento muscular del suelo pélvico en mujeres: protocolo de un ensayo clínico controlado, aleatorizado y doble ciego / Efeitos da estimulação transcraniana por corrente contínua e treinamento muscular do assoalho pélvico em mulheres: protocolo para um ensaio clínico controlado, randomizado e duplo-cego

ABSTRACT Pelvic floor muscle weakness can lead to urinary incontinence, pelvic organ prolapse, and sexual dysfunction. Although it can be minimized by pelvic floor muscle training (PFMT), its effects are not lasting. Therefore, using combination therapy seems promising. This study aims to evaluate the effect of transcranial direct current stimulation (tDCS) combined with PFMT on intravaginal pressure, pelvic floor muscle strength (PFMS), sexual function (SF), and quality of life (QoL) in healthy women. A total of 32 women, aged from 18 to 45 years, will undergo PFMT (with perineal contractions and relaxation) with the aid of pressure biofeedback associated with active tDCS or sham tDCS. Sessions will last 20 minutes, three times per week, for four weeks, totaling 12 sessions. During the protocol, participants will be instructed to also perform the home-based PFMT daily. The tDCS anodal electrode will be positioned over the supplementary motor area of the dominant cortical hemisphere, whereas the cathodal will be over the contralateral supraorbital region, with a 2mA intensity for 20 minutes. Intravaginal pressure (pressure gauge), PFM strength (measured by digital palpation and the PERFECT scheme), FSFI (Female Sexual Function Index), and QoL (SF-36 questionnaire) will be evaluated before and after the 12 sessions and after a 30-day follow-up.

RESUMEN La debilidad de la musculatura del suelo pélvico puede provocar incontinencia urinaria, prolapso de órganos pélvicos y disfunción sexual, y puede minimizarse mediante el entrenamiento de la musculatura del suelo pélvico (EMSP). Sin embargo, este efecto no es duradero. En este contexto, una terapia combinada puede ser prometedora para mejorar la situación. Este estudio tiene por objetivo evaluar el efecto de la estimulación transcraneal por corriente directa (ETCC) combinada con EMSP sobre la presión intravaginal, la fuerza muscular del suelo pélvico (FMSP), la función sexual (FS) y la calidad de vida (CV) en mujeres sanas. Participarán 32 mujeres, de entre 18 y 45 años, que se someterán a EMSP (contracciones y relajación del perineo) y a Biofeedback asociado a ETCC activa o ETCC sham durante 20 minutos, tres veces por semana, durante 4 semanas, con un total de 12 sesiones. Durante el protocolo, las participantes también se someterán diariamente a EMSP en casa. El electrodo anodal de la ETCC se colocará sobre el área motora suplementaria del hemisferio cortical dominante, y el electrodo catodal sobre la región supraorbital contralateral, a una intensidad de 2 mA, durante 20 minutos. Se evaluarán la presión intravaginal (manómetro), la FMSP (palpación digital, esquema Perfect), la FS (Índice de Función Sexual Femenina) y la CV (cuestionario SF-36) antes y después de las 12 sesiones, así como tras un seguimiento de 30 días.

RESUMO A fraqueza muscular do assoalho pélvico pode gerar incontinência urinária, prolapso de órgãos pélvicos e disfunção sexual, e pode ser minimizada pelo treinamento muscular do assoalho pélvico (TMAP). No entanto, este efeito não é duradouro. Assim, terapia combinada parece ser promissora para a melhora deste quadro. Dessa forma, objetiva-se avaliar o efeito da estimulação transcraniana por corrente contínua (ETCC), combinada ao TMAP, sobre a pressão intravaginal, força muscular do assoalho pélvico (FMAP), função sexual (FS) e qualidade de vida (QV) em mulheres saudáveis. Serão 32 mulheres, entre 18 e 45 anos, que realizaram TMAP (contrações e relaxamento do períneo) e Biofeedback associados a ETCC ativa ou ETCC sham por 20 minutos, três vezes por semana, por 4 semanas, totalizando 12 sessões. Durante o protocolo, as participantes também realizarão diariamente, em domicílio, o TMAP. O eletrodo anodal da ETCC será posicionado sobre a área motora suplementar do hemisfério cortical dominante, e o catodal sobre a região supraorbital contralateral, com intensidade de 2mA, por 20 minutos. A pressão intravaginal (manômetro de pressão), FMAP (palpação digital, esquema Perfect), FS (Índice de Função Sexual Feminina) e QV (questionário SF-36) foram avaliadas antes e depois das 12 sessões, bem como após acompanhamento de 30 dias.

Mobile app for pelvic floor muscle training for urinary incontinence during the coronavirus disease 2019 pandemic: clinical trial

SUMMARY OBJECTIVE: The objective of this study was to evaluate the effects of home-based pelvic floor muscle training in women with urinary incontinence, addressing the difficulties arising from social isolation due to the coronavirus disease 2019 pandemic by utilizing a specialized mobile app. METHODS: This randomized, single-group clinical trial aimed to assess the efficacy of pelvic floor muscle training guided by a mobile app (Diario Saúde) in women with stress urinary incontinence. Participants were instructed via telephone to engage in pelvic floor muscle training exercises twice a day for 30 days. Pre- and post-treatment, participants completed validated questionnaires regarding urinary symptoms and quality of life through telephone interviews. Additionally, treatment adherence was evaluated. RESULTS: A total of 156 women were enrolled in the study, with a mean age of 49.3±14.2 years. Significant improvements in urinary incontinence symptoms and quality of life were observed following pelvic floor muscle training guided by the mobile app (p<0.001). Notably, 74.3% of the participants reported performing the exercises with appropriate frequency. Of the participants, 62% reported either complete or substantial improvement in urinary symptoms post-treatment. CONCLUSION: This study revealed notable enhancements in stress urinary incontinence, urinary storage, and overall quality of life subsequent to pelvic floor muscle training guided by a mobile app, particularly during the coronavirus disease 2019 pandemic. The mobile app demonstrated robust acceptance and adherence among women experiencing urinary incontinence.

Significance and techniques of pelvic floor reconstruction in laparoscopic low anterior resection for rectal cancer / 国际外科学杂志

The residual pelvic floor cavity formed by laparoscopic low anterior resection for rectal cancer can result in some complications, such as spread of pelvic infection following anastomotic leakage, adhesive intestinal obstruction, and may increase the probability of radiation intestinal injury in case of postoperative radiotherapy. Reconstructing the pelvic floor can prevent the small intestine from entering the residual cavity, reduce the risk of intestinal obstruction and radiation induced intestinal injury; prevent or reduce the occurrence and severity of anastomotic leakage. Reconstructing the pelvic floor can also improve the anal function after low anterior resection to a certain extent and enhance the quality of life of patients. Direct suturing of the pelvic floor peritoneum and pedicled greater omentum flap graft transplantation are currently two commonly used pelvic floor reconstruction methods, which are relatively simple to operate, easy to promote, and worthy of routine application.

Objective To retrospectively investigate the efficacy of pelvic floor muscle training(PFMT)using APP-based home device in the real-world scenario.Methods A retrospective survey was conducted among 171 000 Chinese female users over 18 years old who freely registered APP and performed PFMT using a domestic manufactured home device from Oct 1,2019 to Mar 31,2021.The Patient Global Impression of Improvement(PGI-I)questionnaires concerning pelvic floor general condition,sexual satisfaction and other three major symptoms related to pelvic floor muscle laxity such as stress urinary incontinence(SUI),pelvic organ prolapse(POP),and vaginal laxity(VL)were broadcast public online for users to self-assess the improvement.The vaginal muscle strength values prior and post training recorded by APP were also reported.All data were collected anonymously for further stratified analysis.Results A total of 984 valid questionnaires were collected by systematic sampling.The PGI-I scores of pelvic floor general condition(P=0.000 1),sexual satisfaction(P=0.009),SUI(P=0.000 1),POP(P=0.044)and VL(P=0.034)were statistically significant in users who reported to use the device for 3 months or more compared with those less than 3 months.In addition,the increase of vaginal muscle strength was related to the improvement of PGI-I scores in SUI and POP with statistical significance.There were no significant difference in subgroups such as age,education,parity,and delivery mode.Conclusion The subjective benefit of pelvic floor function-related symptoms and the improvement of vaginal muscle strength could be observed after PFMT for three months or more using APP-based home device in Chinese women in the real-world scenario.

Expression and Clinical Value of Serum miR-4429 and miR-19-3p in Patients with Pelvic Floor Dysfunctional Disease / 现代检验医学杂志

Objective To investigate the expression and significance of microRNA(miR)-4429 and microRNA(miR)-19-3p level in patients with pelvic floor dysfunctional(PFD)disease.Methods A total of 90 PFD patients admitted to the Second People's Hospital of Hengshui from June 2021 to June 2022 were selected as the PFD group.They were grouped into the pelvic organ prolapse(POP)group(n=50),the stress urinary incontinence(SUI)group(n=25),and the POP combined with SUI group(n=15).Meanwhile,80 healthy women who were examined in the Second People's Hospital of Hengshui were collected as the control group.The general data such as delivery mode,previous abortion history and family history were compared between the control group and the PFD group.The levels of serum miR-4429 and miR-19-3p in each group were compared.The diagnostic value of serum miR-4429 and miR-19-3p levels in PFD was analyzed by receiver operating characteristic(ROC)analysis.Logistic regression analysis was applied to analyze the factors affecting PFD.The paired sample t-test was applied to compare the changes in serum miR-4429 and miR-19-3p levels before and after PFD treatment.Results There were significant differences between the PFD group and the control group in terms of delivery mode,previous abortion history,and PFD family history,and the differences were statistically significant(t=4.415,6.444,4.707,all P＜0.05).The serum miR-4429(0.71±0.19 vs 1.00±0.25)level in the PFD group was lower than that in the control group,while the miR-19-3p(1.44±0.35 vs 1.01±0.28)level was higher than that in the control group,and the differences was statistically significant(t=8.927,8.772,all P＜0.05).The serum miR-4429(0.73±0.22,0.74±0.16 vs 0.59±0.16)level in the POP and SUI groups was higher than that in the POP combined SUI group,while the serum miR-19-3p(1.35±0.39,1.41±0.31 vs 1.77±0.56)level in the POP group and SUI group was lower than that in the POP combined with SUI group,with significant differences(t=3.531,3.411;5.003,3.865,all P＜0.05).ROC analysis showed that the areas under curve(AUC)for miR-4429 and miR-19-3p to assist in assessing whether PFD occurs were 0.805 and 0.825,respectively.The AUC of the combined detection was 0.865.Multivariate logistic regression analysis showed that miR-19-3p was a risk factor affecting PFD,while miR-4429 was a protective factor.After treatment,serum miR-4429(0.93±0.23 vs 0.71±0.19)level in PFD patients increased,while the miR-19-3p(1.12±0.29 vs 1.44±0.35)level decreased,the diffences were statistically significant(t=6.996,6.679,all P＜0.05).Conclusion The serum miR-4429 level in patients with PFD decreased,while the miR-19-3p level increased.The levels of miR-4429 and miR-19-3p in serum were closely related to the occurrence and development of PFD diseases,which can be used as evaluation indicators to predict PFD.

Effects of biofeedback electrical stimulation on stress urinary incontinence and pelvic floor muscle strength during postpartum rehabilitation / 中国医师进修杂志

Objective:To analyze the effect of biofeedback electrical stimulation on the prevention of stress urinary incontinence and pelvic floor muscle strength during postpartum rehabilitation.Methods:A total of 200 parturients who gave birth in Ningde Municipal Hospital of Ningde Normal University from October 2021 to April 2022 were included as research objects and divided into the control group and the observation group according to different rehabilitation programs, with 100 cases in each group. The control group was given routine rehabilitation, and the observation group was given biofeedback electrical stimulation on the basis of the control group, the parturients in the two groups were treated for 3 months. The occurrence of stress urinary incontinence in the two groups was compared, and the pelvic floor muscle strength before and after treatment were compared between the two groups. The scores of International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF) and Pelvic Floor Impact Questionnaire-7 (PFIQ-7) were compared between the two groups.Results:The total incidence of stress urinary incontinence in the observation group was lower than that in the control group: 4.00%(4/100) vs. 15.00%(15/100), there was statistical difference( χ2 = 9.00, P<0.05). After treatment, the muscle strength grade, class Ⅰ muscle fiber, class Ⅱ muscle fiber and average voltage of pelvic floor muscle in the observation group were higher than those in the control group: (3.85 ± 0.27) grades vs. (3.74 ± 0.32) grades, (10.23 ± 1.17) μV vs. (8.84 ± 1.13) μV, (11.56 ± 0.19) μV vs. (10.98 ± 0.24) μV, (18.12 ± 3.24) μV vs. (14.69 ± 3.01) μV, there were statistical differences ( P<0.05). After treatment, the scores of ICI Q-SF and PFIQ-7 in the observation group were lower than those in the control group: (7.02 ± 1.26) scores vs. (8.26 ± 1.15) scores, (18.96 ± 4.31) scores vs. (24.17 ± 5.62) scores, there were statistical differences ( P<0.05). Conclusions:The application of biofeedback electrical stimulation in postpartum rehabilitation can reduce the incidence of stress urinary incontinence, improve postpartum pelvic floor muscle strength, and reduce the impact of stress urinary incontinence and pelvic floor muscle disorder on daily life.

The effect of intraspinal blocking analgesia on delivery quality and puerperal pelvic floor function of primipara / 中国医师进修杂志

Objective:To explore the effects of intraspinal blocking analgesia on the delivery quality and puerperal pelvic floor function of primiparas.Methods:A total of 99 primiparas who delivered in the Second People′s Hospital of Wuhu City from January 2021 to April 2022 were enrolled in this study, 54 patients received intraspinal blocking analgesia (study group) and 45 patients received conventional treatment, without intraspinal blocking analgesia (control group). The delivery quality between the two groups was compared, and the pelvic floor function was evaluated and compared by pelvic floor rehabilitation therapy instrument and pelvic floor ultrasound at 6-8 weeks after delivery.Results:Vaginal delivery were successful in both groups. The total labor duration in the study group was longer than that in the control group: (8.03 ± 2.94) h vs. (6.89 ± 3.49) h, there was statistical difference ( P<0.05). The maximum value of pelvic floor rapid contraction stage, rising time and average value of continuous contraction stage in the study group were higher than those in the control group: (32.85 ± 10.13) μV vs. (14.73 ± 3.25) μV, (0.28 ± 0.06) s vs. (0.22 ± 0.05) s, (30.26 ± 5.24) μV vs. (16.74 ± 4.00) μV, there were statistical differences ( P<0.05). There were no statistical differences in other indicators such as the pre-resting stage, rapid contraction phase recovery time and post-resting stage between the two groups ( P>0.05). The rate of pelvic floor class Ⅰ and class Ⅱ muscle abnormalities at 6-8 weeks after delivery in the study group were lower than those in the control group, but there were no statistical differences ( P>0.05). The maximum Valsalva state hiatus area of levator ani muscle, maximum Valsalva state bladder posterior urethral angle, hiatus area of levator ani muscle at rest state and bladder neck degree in the study group were smaller than those in the control group: (19.09 ± 4.82) cm 2 vs. (23.00 ± 5.34) cm 2, (138.59 ± 23.14)° vs. (148.47 ± 20.38)°, (9.96 ± 2.63) cm 2 vs. (11.60 ± 2.75) cm 2, (20.13 ± 4.37) mm vs. (28.05 ± 6.52) mm, there were statistical differences ( P<0.05). Conclusions:Although intraspinal block analgesia can prolong the total labor time of primipara, but it can reduce the damage of pelvic floor function, possibly by increasing systolic period to protect pelvic floor muscles.

Relationship Between the Anteroposterior Hiatal Diameter and Female Pelvic Organ Prolapse Assessed by Two-Dimensional Pelvic Floor Ultrasound / 中国医学影像学杂志

Purpose To explore the association between the anteroposterior hiatal diameter(AP)and pelvic organ prolapse(POP).Materials and Methods All clinical and transperineal ultrasound(TPUS)data of 262 women with lower urinary tract symptoms or POP who had presented to Second Xiangya Hospital of Central South University from July 2017 to May 2019 were retrospectively summarized and analyzed.AP was measured in the median sagittal section of the pelvic floor at maximum Valsalva motion.The degree of POP was obtained via international continence society(ICS)pelvic organ prolapse quantification(POP-Q)system and TPUS.The relationship between AP and POP degrees,and the predictive ability of AP on POP degrees were analyzed,respectively.Results A total of 237 patients were finally selected.There were 51(21.51％)women within ICS POP-Q stage 0,57(24.05％)within stage Ⅰ,49(20.67％)within stage Ⅱ,44(18.56％)within stage Ⅲ,36(15.18％)within stage Ⅳ.The mean AP on maximal Valsalva was(61.33±10.71)mm(range 37.10-97.90 mm).There was a significant difference in AP measurements based on TPUS or POP-Q(F=52.00,58.18,both P<0.01).A receiver operating characteristic curve analysis proposed a cutoff of 6.0 cm,and the sensitivity and specificity of prediction of obvious POP via TPUS was 81.0％and 75.5％,respectively;the sensitivity and specificity of prediction of POP-Q Ⅱ or high levels POP was 74.5％and 76.0％,respectively.AP was positively highly related to the POP stages.AP on Valsalva of less than 6.0 cm was related to POP stage 0-Ⅰ,6.0 to less than 6.5 cm was related to POP stage Ⅱ,6.5 to less than 7.0 cm to POP stage Ⅱ-Ⅲ,7.0 or more to POP stage Ⅳ(r=0.61,0.47,0.56,0.41,all P<0.05).Conclusion AP≥6.0 cm indicates an enlarged levator hiatus,with likelihood of POP.The larger the AP,the more severe the POP is.

Objective:To investigate the diagnostic value of pelvic floor ultrasound combined with electromyography physiological parameters for postpartum stress urinary incontinence(SUI)of different degrees and pelvic floor function of primipara.Methods:A total of 160 SUI patients who admitted to Yan'an hospital of Kunming City from January 2019 to January 2022 were selected,and they were divided into abnormal group(110 cases)and normal group(50 cases)according to pelvic floor function(the muscle voltage values of different muscle fibers).The SUI was graded according to the Chinese Guidelines for Diagnosis of Urological Diseases and the International Incontinence Advisory Committee's Incontinence Questionnaire(ICI-Q-SF).The posterior horn(α)of bladder and urethra at rest,the displacements of the bladder neck on y-axis(△y)and x-axis(△x)after the rest to the fatigue action,the proximal urethral rotation angle after the rest to the fatigue action(γ),the posterior horn of bladder and urethra(β)after the fatigue action were observed.The electromyography was used to draw and record the pelvic floor myoelectric activity signals of the patients of two groups at five stages(pre baseline rest period,class II muscle fiber systole period,class II and I muscle fiber systole period,class I muscle fiber systole period and post baseline rest period).And then,the muscle voltage values of different muscle fibers on the surface of pelvic floor were quantified.Results:There was no statistically significant difference in Δ x between patients with postpartum SUI of different degrees.There were significant differences in △y,α,β and γ between patients with postpartum SUI of different degrees(F=7.162,7.655,14.998,2.758,P<0.05).The differences of the means of muscle voltages of pre and post baseline rest period,and class I muscle fiber systole period among patients with postpartum SUI of different degrees were not significant.The differences of the means of muscle voltages of class II,and the class II and I muscle fiber systole period among patients with postpartum SUI of different degrees were significant(F=12.062,24.501,P<0.05),respectively.There was no statistically significant difference in △x between the two groups.The △y,α,β and γ of abnormal group were significantly higher than those of normal group(t=8.991,8.691,9.389,27.552,P<0.05),respectively.There were no statistically significant differences in the means of muscle voltage values of the pre and post baseline rest period,and class I muscle fibers systole period between the two groups.The means of muscle voltage values of class II,and class II and I muscle fibers systole period in the abnormal group was significantly higher than them in the normal group(t=9.613,14.452,P<0.05),respectively.The sensitivities of △y,α,β,γ,the means of class II muscle fibers systole period,and the means of class II and I muscle fibers systole period of pelvic floor ultrasound and electromyography physiological parameters were respectively 71.60%,79.40%,81.40%,91.20%,83.30%and 82.40%,and the specificities of them were respectively 41.40%,37.90%,37.90%,60.30%,41.40%,and 44.80%in diagnosing postpartum SUI of different degrees of primipara.The sensitivity and specificity of the combined diagnosis of them were respectively 92.20%and 82.80%in diagnosing postpartum SUI of different degrees of primipara.The sensitivities of △y,α,β,γ,the means of class II muscle fibers systole period,and the means of class II and I muscle fibers systole period of pelvic floor ultrasound and electromyography physiological parameters were respectively 79.10%,77.30%,88.20%,89.10%,77.30%,87.30%,and the specificities of them were respectively 64.00%,64.00%,52.00%,46.00%,70.00%and 66.00%in diagnosing pelvic floor function of primipara.The sensitivity and specificity of the combined diagnosis were respectively 98.20%and 80.00%in diagnosing pelvic floor function of primipara.Conclusion:Pelvic floor electromyography physiological parameters and pelvic floor ultrasonic parameters have a certain value in diagnosing postpartum SUI of different degrees and pelvic floor function,and the value of the combined diagnosis of them is higher.

Lower urinary tract injury in transvaginal reconstructive pelvic surgery / 中华妇产科杂志

Objective:To explore the characteristics, prevention and treatment strategies of lower urinary tract injury in transvaginal reconstructive pelvic surgery (vRPS).Methods:A retrospective analysis was conducted on 24 patients who suffered lower urinary tract injuries occuring in vRPS from January 2005 to June 2021, among which 4 cases were referred to our hospital from other hospitals.Results:(1) In our hospital, 1 952 patients underwent vRPS for anterior and (or) middle pelvic organ prolapse during that study period, with a 1.0% (20/1 952) incidence of lower urinary tract injuries occurring in 20 cases. (2) Ureteral injuries were observed in 14 cases who underwent transvaginal high uterosacral ligament suspension (1.4%, 14/966). The symptoms were relieved after the removal of sutures. (3) Bladder injuries occurred in 6 cases in our hospital, with 4 cases (0.7%, 4/576) in anterior transvaginal mesh surgery (aTVM), one (0.4%, 1/260) in colpocleisis, and one (0.7%, 1/150) in apical suspension for fornix prolapse. An additional 4 cases of bladder injury were referred to our hospital after aTVM. Among the 8 cases of bladder injury during aTVM, 2 cases were intraoperative incidents. Cystoscopy confirmed that the superficial branch or puncture rod of anterior vaginal mesh had penetrated into the bladder. Re-puncturing and placement of the mesh were successfully performed. No abnormalities were observed during a follow-up period of 4-5 years. Postoperative bladder injuries were identified in 6 cases, characterized by mesh erosion into the bladder and formation of calculi. These injuries were confirmed between 6 months to 2 years after vRPS. The exposed mesh and calculi in the bladder were removed through laparotomy or cystoscopy, followed up for 2-12 years. One case experienced slight re-erosion of mesh to the bladder.Conclusions:Lower urinary tract injuries are difficult to avoid in vRPS, particularly in transvaginal high uterosacral ligament suspension and aTVM. However, the incidence is low. Lower urinary tract injuries during vRPS could be easily detected and managed intraoperatively because of the use of cystoscopy. As long-term postoperative complications, erosion of transvaginal mesh to lower urinary tract postoperatively could be treated correctly, seldom with severe sequelae.

Progress on the clinical application of symptom and quality of life survey questionnaires for pelvic floor dysfunction in elderly women / 中华老年医学杂志

Pelvic floor dysfunction is a group of clinical syndromes that occur due to structural damage and dysfunction of the pelvic floor.These syndromes include pelvic organ prolapse, urinary incontinence and pelvic pain.Elderly women have a high prevalence of pelvic floor dysfunction, with approximately 50% being affected.The symptoms of this condition have a significant impact on the quality of life in the elderly population.Therefore, it is crucial to evaluate the severity of symptoms and their impact for the diagnosis and treatment of pelvic floor dysfunction in elderly women.To aid in this evaluation, symptom and quality of life questionnaires are important tools in clinical care.However, the wide range of clinical questionnaires available for pelvic floor dysfunction, which are not specifically tailored to elderly women, has caused confusion among clinicians regarding their selection, utilization, and evaluation.This article utilizes CiteSpace to identify key research areas and frequently used questionnaires in the field.It also introduces methods for applying and assessing symptom and quality of life surveys, with the aim of enhancing clinicians' proficiency in evaluating pelvic floor dysfunction, particularly in elderly women.

Effect of Extralevator Abdominoperineal Excision on Biomechanics of Female Pelvic Floor: A Finite Element Analysis / 肿瘤防治研究

Objective To explore the effects of four extralevator abdominoperineal excision (ELAPE) procedures on the biomechanics of female pelvic floor through finite element analysis. Methods Six finite element models of the female pelvic floor were established, including a normal model, an ELAPE model, and four individual models. The maximum stress in each model was measured under the same pressure, and the stress distribution was observed. Results The maximum stress of non-levator ani muscle tissues on the partially reserved side and totally removed side of the levator ani muscle were 3.101±0.133 and 4.868±0.123 MPa in individual model 1, respectively, which were lower than the maximum stress in the ELAPE model (5.111±0.081 MPa; both P<0.01). The maximum stress in the non-levator ani muscle tissue were 5.138±0.091 MPa on both sides in individual model 2, which were not significantly different from that in the ELAPE model (P>0.05). The maximum stress of non-levator ani muscle tissues were 4.700±0.105 and 3.653±0.156 MPa in individual models 3 and 4, respectively, which were lower than the maximum stress in the ELAPE model (both P<0.01). Conclusion Three ELAPE procedures, including ELAPE with unilateral levator ani muscle resection plane close to the rectum, and the bilateral pubococcygeal muscle lateral resection of levator ani muscle and levator ani muscle in front of the rectum preserved could decrease stress in the non-levator ani muscle tissue on both sides. The effect is evident on the levator ani muscle partially reserved side of ELAPE with unilateral levator ani muscle resection plane close to the rectum. ELAPE with unilateral levator ani muscle resection plane close to the pelvic wall has no significant reduction effect on the non-levator ani muscle tissue on either side.

Study on the therapeutic effect of different magnetic stimulation pelvic floor modes on perimenopausal myofascial pelvic pain syndrome / 重庆医学

Objective To investigate the clinical effect of different magnetic stimulation pelvic floor modes in the treatment of perimenopausal myofascial pelvic pain syndrome(MPSS).Methods A total of 60 perimenopausal women who were clinically diagnosed with MPSS in the hospital from May 2022 to May 2023 were selected as the research objects.They were divided into groups A,B and C by random number table method,with 20 cases in each group.All patients in the three groups were treated with pelvic floor myofascial manual release.Group A was given pelvic floor magnetic stimulation(alternating 10 Hz and 50 Hz),group B was given sacral nerve root magnetic stimulation(50 Hz),and group C was given pelvic floor magnetic stimu-lation combined with sacral nerve root magnetic stimulation at the same time.The three groups were treated twice a week for eight weeks.Visual analogue scale(VAS)was used to evaluate the degree of pelvic floor myofascial tenderness before and after treatment,and Glazer pelvic floor surface electromyography was used to evaluate pelvic floor muscle function.Results Compared with before treatment,the VAS scores of subjec-tive pain and pelvic floor myofascial tenderness in the three groups were decreased after treatment,and the differences were statistically significant(P<0.05).Compared with group A and group B,the VAS score of subjective pain and the VAS score of pelvic floor myofascial tenderness in group C were significantly decreased after treatment,and the differences were statistically significant(P<0.05).Compared with before treatment,the average amplitude and coefficient of variation(CV)of pre-rest potential and post-rest potential in the three groups were decreased after treatment,and the differences were statistically significant(P<0.05).Compared with before treatment,only the maximum amplitude of rapid contraction,the average amplitude of 10 s sustained contraction and 60 s sustained contraction and CV in group C were improved,and the differ-ences were statistically significant(P<0.05).Compared with group A and group B,the average amplitude and CV of pre-resting potential and post-resting potential in group C were decreased after treatment,the maxi-mum amplitude of rapid contraction and the average amplitude and CV of 10 s continuous contraction and 60 s persistent contraction were improved,and the differences were statistically significant(P<0.05).Conclusion Dif-ferent magnetic stimulation pelvic floor modes can effectively relieve pain and improve pelvic floor muscle strength in the treatment of perimenopausal MPSS,and the effect of pelvic floor magnetic stimulation com-bined with sacral nerve root magnetic stimulation is the best.

Sexual function in women with endometriosis and pelvic floor myofascial pain syndrome

Abstract Objective: To evaluate and compare the sexual function and pelvic floor muscles (PFM) function of women with endometriosis and chronic pelvic pain (CPP) with and without Myofascial Pelvic Pain Syndrome (MPPS). Methods: Cross-sectional study conducted between January 2018 and December 2020. Women with deep endometriosis underwent assessments for trigger points (TP) and PFM function using the PERFECT scale. Electromyographic activity (EMG) and sexual function through Female Sexual Function Index (FSFI) were assessed. Statistical analyses included chi-square and Mann-Whitney tests. Results: There were 46 women. 47% had increased muscle tone and 67% related TP in levator ani muscle (LAM). Weakness in PFM, with P≤2 was noted in 82% and P≥3 in only 17%. Incomplete relaxation of PFM presented in 30%. EMG results were resting 6.0, maximal voluntary isometric contraction (MVIC) 61.9 and Endurance 14.2; FSFI mean total score 24.7. We observed an association between increased muscle tone (P<.001), difficulty in relaxation (P=.019), and lower Endurance on EMG (P=.04) in women with TP in LAM. Participants with TP presented lower total FSFI score (P=.02). TP in the right OIM presented increased muscle tone (P=.01). TP in the left OIM presented lower values to function of PFM by PERFECT (P=.005), and in MVIC (P=.03) on EMG. Conclusion: Trigger points (TP) in pelvic floor muscles (PFM) and obturator internus muscle (OIM) correlates with poorer PFM and sexual function, particularly in left OIM TP cases. Endometriosis and chronic pelvic pain raise muscle tone, weaken muscles, hinder relaxation, elevate resting electrical activity, lower maximum voluntary isometric contraction, and reduce PFM endurance.

Botulinum-toxin-A injection following conservative management in patients with dyssynergic defaecation only improves symptoms in the short term: a retrospective study

Objective: Dyssynergic defaecation (DD) is an important cause of chronic constipation. In patients where conservative treatments fail, injections of botulinum toxin A (BTX-A) into the puborectalis and anal sphincter muscles can be effective. Complications of this procedure are reported to be rare and generally mild. This study aimed to identify the complication rates and short- to medium-term success rates of BTX-A injections as a treatment for DD. Methods: A retrospective review was conducted on patients diagnosed with DD who had undergone BTX-A injections at a functional colorectal unit. Patient demographics, manometric assessment, conservative management, and injection technique were collected through a chart review. Subjective patient reports and comparison of pre- and postprocedure symptom scores were used to determine efficacy. Results: The 21 patients included (24 procedures, with 3 patients receiving BTX-A on two separate occasions) all received stool modification and dietary advice, and 20 patients underwent pelvic floor physiotherapy, averaging 8 sessions. The injections were universally applied under general anesthetic, primarily targeting the anal sphincter and/or puborectalis muscles. There were 6 reports of faecal urge/incontinence, with all but one being resolved within weeks. The BTX-A injection was subjectively reported as beneficial in 19 cases, averaging 4.7 months (range 1-32) of improvement. Only 2 were sustained beyond 12 months. Despite overall improvements in symptom scores from pre- to postprocedure, none were statistically significant. Conclusion: Following a course of conservative management, the BTX-A injection appears to be a safe treatment for DD, but only has short term efficacy. (AU)

Associação da educação sexual, cinesioterapia e terapia manual no tratamento de mulheres anorgásmicas: um estudo de caso / Association of sex education, kinesiotherapy and manual therapy in the treatment of anorgasmic women: a case study

O orgasmo é o ápice da excitação sexual e, quando comumente não experienciado, denomina-se anorgasmia, segunda queixa sexual mais frequente entre mulheres. A fisioterapia é um recurso que visa beneficiar a qualidade de vida das mulheres anorgásmicas por meio da prevenção, reparação de função e tratamento de quadros álgicos. O estudo teve como objetivo avaliar os efeitos da associação das técnicas de cinesioterapia aplicada à musculatura do assoalho pélvico, massagem perineal e conscientização acerca da sexualidade das participantes. Os métodos utilizados foram educação sexual, massagem perineal e cinesioterapia associada ao uso da sonda uroginecológica New PelviFit Trainer, como biofeedback visual, para promover conscientização e estimar os efeitos sobre a condição da musculatura do assoalho pélvico de mulheres com relato de anorgasmia. O resultado obtido com o protocolo da associação das técnicas terapêuticas em mulheres com disfunção orgásmica apresentou melhora da função sexual feminina, aumento da força e do estado de relaxamento da musculatura do assoalho pélvico, avaliados pelo questionário Índice de Função Sexual Feminina, quantificados por meio da escala de Oxford modificada e da escala de avaliação de flexibilidade vaginal, respectivamente. Como conclusão, a aplicação das técnicas fisioterapêuticas aliadas ao tratamento humanizado, com enfoque na conscientização das mulheres, autopercepção corporal e manutenção da função sexual, promoveu melhora da disfunção sexual orgásmica. Apesar de necessário maior embasamento científico relativo ao tema, a presente abordagem para o tratamento em questão apresentou-se promissora e pertinente à base de dados. (AU)

Adherencias del capuchón del clítoris al glande: una condición poco estudiada y poco examinada / Clitoral hood adhesions to the glans penis: an understudied and under-examined condition

INTRODUCCIÓN: El clítoris es una de las estructuras vulvares menos examinadas, pese a su relevancia en la vida sexual y sus importantes relaciones anatómicas. Las adherencias del capuchón del clítoris han sido descritas y clasificadas según la exposición del glande, siendo relacionadas con trastornos del deseo sexual. La inervación del clítoris depende de raíces de S3-S4, siendo posible que síntomas frecuentes del piso pélvico tengan relación con esta condición. Realizamos un análisis retrospectivo de pacientes de policlínico de piso pélvico entre noviembre de 2021 y abril de 2022. Se incluyeron 100 pacientes con adherencias al ingreso. RESULTADOS: Promedio de edad 45,8 ± 15,5 años. Las adherencias fueron el 19% leves, el 62% moderadas y el 18% graves. Los principales síntomas eran mal vaciado vesical (38%), dolor (28%), disfunción sexual (39%) y síntomas irritativos vesicales (43%); solo una paciente fue asintomática. El área visible promedio del clítoris era de 20,7 ± 13,7 mm2. CONCLUSIONES: Las adherencias del capuchón del clítoris son un hallazgo común, muchas veces no diagnosticadas, por lo que su evaluación debe ser parte de la exploración física. Pueden asociarse a sintomatología de piso pélvico.

INTRODUCTION: The clitoris is one of the least examined vulvar structures despite its relevance in sexual life and important anatomical relationships. Clitoral hood adhesions have been described in the literature, classified based on glans exposure, and related to sexual desire disorders. The innervation of the clitoris depends on the roots of S3-S4, and frequent pelvic floor symptoms may be associated with this condition. We retrospectively analyzed the clinical record of patients admitted to a pelvic floor clinic between November 2021 and April 2022. One hundred patients with adhesions at the time of admission were registered. RESULTS: Average 45.8 ± 15.5 years. Clitoral hood adhesions were mild (19%), moderated (62%), or severe (18%). The main symptoms were voiding dysfunction symptoms (38%), pain (28%), sexual dysfunction (39%), and irritative bladder symptoms (43%); only one patient was asymptomatic. The visible area of the clitoris was 20.7 ± 13.7 mm2. CONCLUSIONS: Adhesions of the clitoral hood are often undiagnosed, and its analysis should be part of the physical exam. Clitoral hood adhesions could be associated with pelvic floor symptoms.
