CO 2 laser, radiofrequency, and promestriene in the treatment of genitourinary syndrome of menopause in breast cancer survivors: a histomorphometric evaluation of the vulvar vestibule.

OBJECTIVE: This study aimed to compare the efficacy of CO 2 laser, radiofrequency, and promestriene in treating genitourinary syndrome of menopause in women with breast cancer receiving adjuvant therapy and to analyze the clinical and histological findings of the vulvar vestibule. METHODS: Women with moderate-to-severe symptoms of vulvar atrophy were enrolled. The participants were evaluated according to pretreatment and posttreatment protocols using the visual analog scale and clinical assessments, which included a gynecological examination and vestibular biopsy. Participants were randomly assigned into the laser, radiofrequency, or promestriene groups. Participants in the energy treatment groups underwent three consecutive monthly outpatient vulvovaginal treatment sessions, whereas those in the control group were administered promestriene for 4 months. During a follow-up visit 30 days posttreatment, the participant global posttreatment impression of improvement was evaluated using a Likert scale. RESULTS: Seventy women completed treatment. Histological vulvar atrophy was identified in four (5.7%) of the pretreatment vulvar samples. Postintervention, all histological parameters were normalized. Significant improvements in symptoms were observed, as all three groups showed a reduction in the visual analog scale score, with no statistically significant differences among them. A high level of satisfaction was reported posttreatment in all groups. No damage to the histological structure of the vulvar vestibule or relevant clinical adverse events were identified posttreatment. CONCLUSIONS: Laser, radiofrequency, and promestriene delivered comparable, significant symptom improvements among women with breast cancer receiving adjuvant therapy. These treatments did not cause structural tissue damage or other clinical complications.

Historical perspective of vaginal hysterectomy: the resilience of art and evidence-based medicine in the age of technology.

OBJECTIVE: The aim of this study was to describe, from a historical perspective, the relevance, resilience and outcomes of vaginal hysterectomy (VH) in gynecology in the age of technological scenario. METHODS: The authors searched records from January 2011 to January 2021 on the following databases: Medline, EMBASE, and CENTRAL (The Cochrane Library) for combinations of the terms "vaginal hysterectomy," "outcomes" AND "history"; and before that period, if the search had historical relevance. INCLUSION CRITERIA: randomized clinical trials; hysterectomy performed for benign gynecological conditions; and VH outcomes compared with Abdominal Hysterectomy (AH), Laparoscopic Hysterectomy (LH) or Robotic Hysterectomy (RH). RESULTS: The VH combines sequences of reproducible techniques which have been developed over the years to safely and effectively overcome the limitations of difficult cases of vaginal extirpation from the uterus. CONCLUSION: The authors support endoscopic surgical approaches in complex surgery for benign indications, urogynecology, and gynecologic oncology when appropriate. However, what makes the gynecological surgeon different from the general surgeon is the vaginal access. It is essential to continue to train residents in vaginal surgical skills and provide safe and cost-effective patient care. The art of technology is the resilience of keeping only the patient at the center of innovation.

Incidence of Bacteriuria after Urodynamic Study with or without Antibiotic Prophylaxis in Women with Urinary Incontinence.

Introduction The presence of bacteria in urine is called bacteriuria, which may be symptomatic or asymptomatic. The manipulation of the urinary tract during urodynamic study (UDS), which is an invasive procedure, can result in urinary tract infection (UTI). Studies on the use of prophylactic antibiotics for UDSs are contradictory. Some investigators concluded that they were valuable and others did not. The objective of this study is to evaluate the efficacy of antibiotic prophylaxis before UDS. This is a placebo-control randomized double-blind study. Methods Two-hundred and seventeen women affected by urinary incontinence were eligible for this study. All patients had presented negative urine culture previous to the UDS. They were randomized in four groups: group A received placebo, group B received 500 mg of levofloxacin, group C received 80 mg trimethoprim and 400 mg sulfamethoxazole and group D received 100 mg of nitrofurantoin. A urine culture was performed 14 days after the UDS. Results We observed asymptomatic bacteriuria after the UDS in five patients in group A, one in group B, one in group C and one in group D. Only one patient on group A had symptomatic bacteriuria. We didn't observe statistical difference between the groups. When we recategorized the patients in two groups, the incidence of bacteriuria was significantly higher in the placebo group compared with the antibiotic group. Conclusion The conclusion is that antibiotic prophylaxis before the UDS did not reduce the incidence of UTI in women within the target population.

Introdução A presença de bactéria na urina é denominada bacteriúria, que pode ser sintomática ou assintomática. A manipulação do trato urinário pelo estudo urodinâmico (EUD), que é um procedimento invasivo, pode resultar em infecção do trato urinário (ITU). Os estudos sobre o uso de profilaxia antibiótica para EUD são contraditórios. Alguns investigadores concluíram que era necessário e outros não. O objetivo deste estudo é avaliar a eficácia da antibióticoprofilaxia antes da realização do EUD. Trata-se de um estudo randomizado duplo-cego. Métodos Duzentas e dezessete mulheres com queixa de incontinência urinária foram recrutadas para este estudo. Todas as pacientes apresentaram urocultura negativa antes do EUD. As pacientes foram randomizadas em quatro grupos: o grupo A recebeu placebo, o grupo B recebeu 500 mg de levofloxacina, o grupo C recebeu 80 mg de trimetoprim e 400 mg de sulfametoxazol e o grupo D recebeu 100 mg de nitrofurantoína. Uma urocultura foi realizada 14 dias após o EUD. Resultados Observamos bacteriúria assintomática após o EUD em cinco pacientes do grupo A, uma no grupo B, uma no grupo C e uma no grupo D. Apenas uma paciente do grupo A apresentou bacteriúria sintomática. Não observamos diferença estatística entre os grupos. Quando recategorizamos as pacientes em dois grupos, a incidência de bacteriúria foi significativamente maior no grupo placebo em comparação com o grupo antibiótico. Conclusão A conclusão deste estudo é que a antibióticoprofilaxia antes do EUD não reduz a incidência de ITU nesse grupo de mulheres.

Reproducibility in pelvic floor biometric parameters of nulliparous women assessed by translabial three-dimensional ultrasound using Omniview reformatting technique.

AIM: To assess the reproducibility of pelvic floor biometric parameters by translabial three-dimensional ultrasound compared with the OmniView® reformatting technique. MATERIAL AND METHODS: We performed a cross-sectional study involving 47 nulliparous women without symptoms of pelvic floor dysfunction. The hiatal area and right pubovisceral muscle width measurements were performed in the axial plane using both 3D ultrasound in the rendering mode and OmniView® techniques. To determine the occurrence of standardized error between examiners and the two sonographic methods, the paired t-test was used. The intra- and inter-observer reliability and agreement were estimated by concordance correlation coefficient (CCC) and limits of agreement, respectively. RESULTS: We did not observe significant statistical differences among both measurements performed by the first examiner, both examiners and both methods in the assessment of the hiatal area; however, the measurements of the right pubovisceral muscle were significantly lower using OmniView®. The intra-observer reliability was good in the evaluation of all pelvic floor parameters; however, the inter-observer reliability was good only to the 3D rendering mode (CCC=0.87). The intra-observer agreement was good in the assessment of all pelvic floor parameters; however, the inter-observer agreement was found to be good only when 3DUS in the rendering mode was used (<+/-15%). CONCLUSION: Both 3D ultrasound in the rendering mode and OmniView® reformatting techniques were concordant in the assessment of pelvic floor parameters; however, the 3D ultrasound rendering in the mode demonstrated better inter-observer reliability and agreement.

Effectiveness of adding voluntary pelvic floor muscle contraction to a Pilates exercise program: an assessor-masked randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to evaluate the effectiveness of adding voluntary pelvic floor muscle contraction (PFMC) to a Pilates exercise program in sedentary nulliparous women. METHODS: Fifty-seven healthy nulliparous and physically inactive women were randomized to a Pilates exercise program (PEP) with or without PFMC. Forty-eight women concluded this study (24 participants for each group). Each woman was evaluated before and after the PEP, by a physiotherapist and an urogynecologist (UG). Neither of the professionals was revealed to them. This physiotherapist measured their pelvic floor muscle strength by using both a perineometer (Peritron) and vaginal palpation (Oxford Scale). The UG, who performed 3D perineal ultrasound examinations, collected their data and evaluated the results for pubovisceral muscle thickness and the levator hiatus area (LA). Both professionals were blinded to the group allocation. The protocol for both groups consisted of 24 bi-weekly 1-h individual sessions of Pilates exercises, developed by another physiotherapist who specializes in PFM rehabilitation and the Pilates technique. RESULTS: The PEP+ PFMC group showed significantly greater strength improvements than the PEP group when comparing the Oxford scale, vaginal pressure and pubovisceral muscle thickness during contraction measurements at baseline and post-treatment. CONCLUSIONS: Our findings suggest that adding a voluntary PFMC to a Pilates exercise program is more effective than Pilates alone in improving PFM strength in sedentary nulliparous women.

Oestrogen receptor alpha expression in neovaginal tissue of women following modified Abbé-McIndoe technique and in premenopausal women.

The aim of the study was to compare the expression of oestrogen receptor alpha (ERα) in neovaginal tissue of patients with vaginal agenesis following neovaginoplasty using regenerated, oxidised cellulose in premenopausal women. A prospective, observational case-control study was performed on eight patients with vaginal agenesis following modified Abbé-McIndoe neovaginoplasty and 10 control premenopausal women following benign gynaecologic surgery. 6F11 monoclonal antibody was used to determine ERα expression in the vaginal mucosa. Quantitative and qualitative evaluations were performed, respectively, in vaginal epithelium and stroma. The thickness of the vaginal epithelium was determined as the vertical distance between the basal layer cells and the apical surface of the superficial layer. The percentage of ERα-expressing cells was higher in the control group, except in the superficial zone of the epithelium. In the stromal tissue, ERα was detected in only one patient from the neovagina group compared with nine women in the control group. The neovagina group had a statistically thinner epithelium. Our study suggests that women with vaginal agenesis following modified Abbé-McIndoe neovaginoplasty using regenerated oxidised, cellulose experience relatively local hypo-oestrogenism in the first year after surgery, with repercussion in vaginal trophism.

Multicenter, randomized trial comparing native vaginal tissue repair and synthetic mesh repair for genital prolapse surgical treatment.

INTRODUCTION AND HYPOTHESIS: This trial aimed to compare the outcomes of native vaginal tissue repair versus polypropylene mesh repair for the treatment of severe genital prolapse. METHODS: This multicenter randomized trial included 184 women, with POP-Q stage 3 or 4. They were randomly assigned to undergo surgical treatment using native tissue repair (n = 90) or synthetic mesh repair (n = 94). Native tissue repair surgery was performed according to site-specific defects, including sacrospinous ligament fixation for apical defects. Mesh repair (Prolift™) was performed in accordance with manufacturer recommendations. Hysterectomy was performed in all cases of uterine prolapse. Statistical tests were used to compare between-group and within-group differences before the surgery and at 1-year follow-up. We considered cure to have occurred when the POP-Q point evaluation was equal to or less than 0 and POP-Q point C better than or equal to half the total vaginal length (TVL) after 1 year. The patients answered the Prolapse Quality-of-Life Questionnaire (PQoL) and the Sexual Quotient Female Version (QS-F) questionnaire. RESULTS: Both groups were homogeneous preoperatively. There were no differences between the groups in operative time, complications or pain. At 1-year follow-up, anatomical cure rates were better in the mesh group in the anterior compartment (p = 0.019). Significant improvement in PQoL scores at 1-year follow up were observed in each group; between-group comparisons of changes in PQoL scores revealed greater improvement in the mesh group. CONCLUSION: Both techniques were effective. Anatomical efficacy was superior in the mesh group regarding the anterior compartment; quality of life changes were also greater in the mesh group. Complications were significantly higher in the mesh group.

Ultrasound thickness of bladder wall in continent and incontinent women and its correlation with cystometry.

OBJECTIVE: To compare bladder wall thickness in two kinds of urinary incontinent women-stress urinary incontinence (SUI) and overactive bladder (OAB) with urodynamic detrusor overactivity (DO), and to compare them with continent patients by ultrasound, also, correlate with cystometric results in incontinent women. METHODS: 91 women were divided into the following groups: continent (n = 31), SUI (n = 30), and DO (n = 30) groups after clinical evaluation and urodynamic test (only in incontinent women). Transvaginal ultrasound was performed to the bladder wall thickness (BWT) measurement. The mean of BWT was calculated and data were analyzed with ANOVA and Turkey's multiple comparison tests. Pearson's correlation coefficient (r) was used to compare two variables. Receiver operating characteristic (ROC) curve was performed to study BWT as a diagnostic parameter. RESULTS: BWT in DO group was significantly higher than that in the other groups (P < 0.005). A moderate positive correlation was found between BWT and maximum bladder pressure during involuntary bladder contraction. There was no difference in BWT between SUI and continent groups. DO group had lower first desire to void and cystometric capacity. Maximum bladder pressure at detrusor contraction had a moderate positive correlation with BWT. The ROC revealed an area under the curve of 0.962 (95% CI, 0.90-1.01). CONCLUSIONS: DO patients have increased bladder wall thickness, lower first desire to void, and lower cystometric capacity. There was a moderate correlation between BWT and maximum bladder pressure during involuntary bladder contraction.

Assessing the impact of twin pregnancies on the pelvic floor using 3-dimensional sonography: a pilot study.

OBJECTIVES: The purpose of this study was to compare the morphologic characteristics of the pelvic floor musculature between women with twin and singleton pregnancies. METHODS: We conducted a cross-sectional case-control study of 40 nulliparous women aged 20 to 38 years to compare women with singleton pregnancies (n = 23) to women with twin pregnancies (n = 17). Biometric measurements of the levator hiatus and the sagittal and coronal diameters were made by transperineal 3-dimensional sonography between the 28th and 38th gestational weeks. Comparisons were statistically assessed by the unpaired Student t test and Mann-Whitney U test. RESULTS: For the women with singleton pregnancies, the mean sagittal diameters at rest, during the Valsalva maneuver, and during pelvic floor contraction were 5.3, 5.7, and 4.5 cm, respectively, and the mean coronal diameters under these conditions were 3.8, 4.1, and 3.6 cm. For the women with twin pregnancies, the corresponding values were as follows: mean sagittal diameters, 5.3, 5.8, and 4.6 cm; and mean coronal diameters, 4.3, 4.3, and 3.8 cm. The differences in coronal diameters were statistically significant at rest (P < .01) and during contraction (P = .04). The mean levator hiatal areas for the women with singleton pregnancies were 14.6, 16.9, and 11.7 cm(2) at rest, during Valsalva, and during contraction, respectively; for the women with twin pregnancies, these values were 16.0, 18.6, and 12.6 cm(2). CONCLUSIONS: Hiatal measurements were higher in twin than in singleton pregnancies, with coronal diameters reaching significance at rest and during contraction, suggesting that pelvic support undergoes greater changes during twin pregnancy.

Assessment of pelvic floor of women runners by three-dimensional ultrasonography and surface electromyography. A pilot study.

AIM: To evaluate female runners' pelvic floor muscles using three-dimensional ultrasonography (3DUS) and surface electromyography (SEMG). MATERIAL AND METHODS: A cross-sectional study was conducted on 24 female runners. SEMG was performed using surface electrodes inserted in the vagina. 3DUS was performed using perineal convex transducer. SEMG was evaluated at rest and with maximum voluntary contraction (MVC) and slow contraction. Levator ani muscle thickness, levator hiatus area and the angle between the levator muscles at rest and with MVC and Valsalva were evaluated using 3DUS. The women were divided into two groups (women running 25 km/week). Means, standard deviations and non-paired t tests were used for both groups. RESULTS: Among the 24 women, 11 ran 25 km/week (40.77 +/- 1.15 km/week). The mean SEMG at rest and with MVC and slow contraction were 16.25, 65.86 and 71.41 mV, respectively. For the levator hiatus area at rest and with MVC and Valsalva, the means were 12.54, 10.06 and 16.57 sqcm, respectively. Correlations between 3DUS and SEMG showed significant differences in SEMG at rest and levator thickness with Valsalva (r = 0.46; p = 0.04). CONCLUSIONS: 3DUS and SEMG are two feasible methods for evaluating female runners' pelvic floor. Correlations between 3DUS and SEMG showed significant differences in SEMG at rest and levator thickness with Valsalva.

Role of estrogen receptor alpha on vaginal epithelialization of patients with Mayer-Rokitansky-Kuster-Hauser syndrome submitted to neovaginoplasty using oxidized regenerated cellulose.

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to evaluate the expression of estrogen receptor alpha (ERα) on the neovaginal tissue of patients with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome submitted to modified Abbé-McIndoe neovaginoplasty using oxidized regenerated cellulose. METHODS: The current study involved eight subjects with MRKH syndrome. Serial samples of the neovagina were obtained after the surgery and immunohistochemical detection of ERα was performed using antibody NCL-L-ER-6F11. RESULTS: The operation was performed successfully in all subjects without complications. A total of 22 samples of neovaginal tissue were analyzed. The expression of ERα was detected only 6 months after the surgery, when the neovagina acquired characteristics of normal vagina. CONCLUSION: In our study, the expression of ERα occurred when complete epithelialization of vaginal tissue was observed. Other mechanisms may be involved in the formation of vaginal epithelium in patients with MRKH syndrome.

Efficacy of pelvic floor muscle training and hypopressive exercises for treating pelvic organ prolapse in women: randomized controlled trial / Eficácia do treinamento da musculatura do assoalho pélvico e de exercícios hipopressivos para o tratamento do prolapso de órgãos pélvicos em mulheres: ensaio clínico randomizado

CONTEXT AND OBJECTIVE: Previous studies have shown that women with pelvic floor dysfunctions present decreased cross-sectional area (CSA) of the levator ani muscle. One way to assess the effects of training programs is to measure the CSA of the muscle, using ultrasonography. The aim here was to evaluate the efficacy of pelvic floor muscle training and hypopressive exercises for increasing the CSA of the levator ani muscle in women with pelvic organ prolapse. DESIGN AND SETTING: Prospective randomized controlled trial at the Urogynecology outpatient clinic of Universidade Federal de São Paulo. METHODS: Fifty-eight women with stage II pelvic organ prolapse were divided into three groups for physiotherapy: a pelvic floor muscle training group (GI); a hypopressive exercise group (GII); and a control group (GIII). The patients underwent transperineal ultrasonographic evaluation using a transducer of frequency 4-9 MHz. The (CSA) of the levator ani muscle was measured before physiotherapy and after 12 weeks of treatment. RESULTS: The groups were homogeneous regarding age, number of pregnancies, number of vaginal deliveries, body mass index and hormonal status. Statistically significant differences in CSA were found in GI and GII from before to after the treatment (P < 0.001), but not in relation to GIII (P = 0.816). CONCLUSIONS: The CSA of the levator ani muscle increased significantly with physiotherapy among the women with pelvic organ prolapse. Pelvic floor muscle training and hypopressive exercises produced similar improvements in the CSA of the levator ani muscle.

CONTEXTO E OBJETIVO: Estudos anteriores mostraram que mulheres com disfunção do assoalho pélvico possuem diminuição da área de secção transversal (AST) do músculo levantador do ânus. Uma forma de avaliar os efeitos de um programa de treinamento é mensurar a AST do músculo por ultrassonografia. O objetivo foi avaliar a eficácia do treinamento da musculatura do assoalho pélvico e de exercícios hipopressivos no aumento da AST do músculo levantador do ânus em mulheres com prolapso de órgãos pélvicos. TIPO DE ESTUDO E LOCAL: Estudo prospectivo, randomizado e controlado realizado no Ambulatório de Uroginecologia da Universidade Federal de São Paulo. MÉTODOS: Cinquenta e oito mulheres com prolapso de órgãos pélvicos estádio II foram divididas em três grupos para tratamento fisioterapêutico: (GI) grupo de treinamento dos músculos do assoalho pélvico, (GII) grupo de exercícios hipopressivos e (GIII) grupo controle. As pacientes se submeteram a avaliação ultrassonográfica transperineal com transdutor de frequência 4-9 MHz. Foi mensurada a AST do músculo levantador do ânus antes e após 12 semanas de tratamento fisioterapêutico. RESULTADOS: Os grupos foram homogêneos no que se refere a idade, número de gestações, número de partos vaginais, índice de massa corpórea e estado hormonal. Diferença significante foi observada na AST de GI e GII antes e após o tratamento (P < 0,001) e isso não ocorreu com o GIII (P = 0,816). CONCLUSÕES: A AST do músculo levantador do ânus aumentou significativamente com tratamento fisioterapêutico em mulheres com prolapso de órgãos pélvicos. Treinamento dos músculos do assoalho pélvico e exercícios hipopressivos são semelhantes no que se refere ao aumento da AST do músculo levantador do ânus.
