Abstract
Objective We aimed to evaluate the efficacy of topical estrogen after transvaginal tension-free vaginal tape-obturator (TVT-O) in the treatment of de novo overactive bladder symptoms that appear after surgery. Methods This is a prospective randomized controlled study performed in the Urology and Gynecology Departments, Kasr Al Ainy Hospital, Cairo University, Cairo, Egypt. Two hundred and ten postmenopausal females presenting during the period between January 2017 and November 2020 with stress urinary incontinence were included in the study. Patients were divided into two groups, 105 patients in Group A (treatment group) and 105 patients in Group B (control group). Patients in Group A underwent transvaginal TVT-O followed by local vaginal estrogen treatment for 6 months, while patients in Group B underwent transvaginal TVT-O only. The study included any postmenopausal female with urodynamic stress urinary incontinence. All patients had to fulfill a 3-day bladder diary, overactive bladder symptoms score, urine analysis, urodynamic study, and post-voiding residual urine measurement by abdominal ultrasound preoperatively and at 3-month and 6-month follow-ups. Results At 6-month follow-up, daytime frequency was reduced to 8% in Group A (increased to 21% in Group B) with a statistically significant difference between both groups (p=0.009). At 6-month follow-up, nocturia was 8% in Group A (11% in Group B) with no statistically significant difference between both groups (p=0.469). There was a statistically significant difference between both groups as regards to urinary urgency at 6-month follow-up (p=0.024). There was a statistically significant difference in postoperative wound healing events as regards to cure, hyperemia, gapping, and wound infection 1 week after intervention between both groups (p=0.008). No local or systemic side-effects were reported from local estrogen use. Conclusion Local vaginal estrogen treatment given to postmenopausal patients after midurethral sling procedures can reduce the symptoms of daytime frequency and urinary urgency. Long-term follow-up is needed.

Abstract
BACKGROUND Pelvic organ prolapse (POP) is the descent of a woman's uterus, bladder, or rectum into the vagina. It affects 50% of women over 50 years old who have given birth to at least one child, and recognised risk factors are older age, higher number of births, and higher body mass index. This review assesses the effects of oestrogen therapy, alone or in combination with other treatments, on POP in postmenopausal women. OBJECTIVES To assess the benefits and harms of local and systemic oestrogen therapy in the management of pelvic organ prolapse symptoms in postmenopausal women, and to summarise the principal findings of relevant economic evaluations. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register (up to 20 June 2022), which includes CENTRAL, MEDLINE, two trials registers, and handsearching of journals and conference proceedings. We also checked the reference lists of relevant articles for additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs), quasi-RCTs, multi-arm RCTs, and cross-over RCTs that evaluated the effects of oestrogen therapy (alone or in combination with other treatments) versus placebo, no treatment, or other interventions in postmenopausal women with any grade of POP. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data from the included trials using prespecified outcome measures and a piloted extraction form. The same review authors independently assessed the risk of bias of eligible trials using Cochrane's risk of bias tool. Had data allowed, we would have created summary of findings tables for our main outcome measures and assessed the certainty of the evidence using GRADE. MAIN RESULTS We identified 14 studies including a total of 1002 women. In general, studies were at high risk of bias in terms of blinding of participants and personnel, and there were also some concerns about selective reporting. Owing to insufficient data for the outcomes of interest, we were unable to perform our planned subgroup analyses (systemic versus topical oestrogen, parous versus nulliparous women, women with versus without a uterus). No studies assessed the effects of oestrogen therapy alone versus no treatment, placebo, pelvic floor muscle training, devices such as vaginal pessaries, or surgery. However, we did identify three studies that assessed oestrogen therapy in conjunction with vaginal pessaries versus vaginal pessaries alone and 11 studies that assessed oestrogen therapy in conjunction with surgery versus surgery alone. AUTHORS' CONCLUSIONS There was insufficient evidence from RCTs to draw any solid conclusions on the benefits or harms of oestrogen therapy for managing POP symptoms in postmenopausal women. Topical oestrogen in conjunction with pessaries was associated with fewer adverse vaginal events compared with pessaries alone, and topical oestrogen in conjunction with surgery was associated with reduced postoperative urinary tract infections compared with surgery alone; however, these findings should be interpreted with caution, as the studies that contributed data varied substantially in their design. There is a need for larger studies on the effectiveness and cost-effectiveness of oestrogen therapy, used alone or in conjunction with pelvic floor muscle training, vaginal pessaries, or surgery, for the management of POP. These studies should measure outcomes in the medium and long term.

Abstract
INTRODUCTION AND HYPOTHESIS The objective of this narrative review is to describe changes in urethral function that occur during a woman's lifetime. Evaluation of urethral function includes measurements of urethral closure pressure, at rest and during stress, leak point pressure, and the detailed study of anatomical and histological changes of the urethral sphincteric mechanism. METHODS A literature search in MEDLINE, PubMed, and relevant journals from 1960 until 2020 was performed for articles dealing with urethral function and the impact of aging, pregnancy, and childbirth, female hormones, and menopausal transition on the urethral sphincteric mechanism. Longitudinal and cross-sectional epidemiological surveys, studies on histological changes in urethral anatomy during aging, and urodynamic data obtained at different points in a woman's lifetime, during pregnancy, after childbirth, as well as the effects of female hormones on urethral sphincter function are reviewed. Relevant studies presenting objective data are analyzed and briefly summarized. RESULTS AND CONCLUSIONS The findings lead one to conclude that a constitutional or genetic predisposition, aging, and senescence are the most prominent etiological factors in the development of urinary incontinence and other pelvic floor disorders. Vaginal childbirth dilates and may damage the compressed pelvic supportive tissues and is invariably associated with a decline in urethral sphincter function. Pregnancy, hormonal alterations, menopausal transition, weight gain, and obesity are at best of secondary influence on the pathology of lower urinary tract dysfunction. The decline of circulating estrogens during menopausal transition may play a role in the transition of fibroblasts to cellular senescence.

Abstract
BACKGROUND Fecal incontinence (FI) generally occurs with anal sphincter damage caused by vaginal delivery in women, obvious FI can develop in the postmenopausal stage. This pelvic floor dysfunction has no rational medical therapeutic options. We investigated the effect of testosterone treatment on the anal sphincter structure, serum thiol/disulfide levels, uterine tissue, and body composition in female rats in an experimental menopause-FI model. METHODS The animal experiments were performed between September and November 2020 at Experimental Animal Application and Research Center, Afyon Kocatepe University, Afyonkarahisar, Turkey. Thirty-two female rats were divided into four groups: sham, saline, 10 mg/kg testosterone undecanoate, 100 mg/kg testosterone undecanoate. Except for the sham group, all the other groups underwent ovariectomy (OVE) to create a menopause model. Two weeks after this procedure, the FI model was created under general anesthesia in all rat groups. At the end of the experiment, the rats were placed under general anesthesia, weighed, and euthanized after recording the data. The anal sphincter region and uterine tissue samples were collected for histopathological examinations, and blood samples were collected for total testosterone and thiol/disulfide homeostasis analyses. RESULTS An increase in anal sphincter muscles and connective tissue thickness was observed in the testosterone-administered groups (p = 0.001). No difference was detected between the groups in the total thiol, native thiol, and disulfide balance (p = 0.087, p = 0.604, p = 0.092). The testosterone-treated groups did not have severe uterine epithelial degradation, hyperemia, or increased endometrial thickness (p = 0.186, p = 0.222, p = 0.630). The body weight of all rats increased (p < 0.05), but the omental weight did not increase (p = 0.061). DISCUSSION Testosterone treatment increased the anal sphincter muscle and connective tissue thickness without causing any oxidative stress and did not result in a pathological change in the uterine tissue and body fat composition.

Abstract
Background and Objectives: Insufficient connective urethra and bladder support related to childbirth and menopausal estrogen decrease leads to stress urinary incontinence (SUI). The aim of this review is to narratively report the efficacy and safety of new mini-invasive solutions for SUI treatment as laser energy devices, in particular, the microablative fractional carbon dioxide laser and the non-ablative Erbium-YAG laser. Materials and Methods: For this narrative review, a search of literature from PubMed and EMBASE was performed to evaluate the relevant studies and was limited to English language articles, published from January 2015 to February 2022. Results: A significant subjective improvement, assessed by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) was reported at the 6-month follow up, with a cure rate ranged from 21% to 38%. A reduction of effect was evidenced between 6 and 24–36 months. Additionally, the 1-h pad weight test evidence a significant objective improvement at the 2–6-month follow up. Conclusions: SUI after vaginal laser therapy resulted statistically improved in almost all studies at short-term follow up, resulting a safe and feasible option in mild SUI. However, cure rates were low, longer-term data actually lacks and the high heterogeneity of methods limits the general recommendations. Larger RCTs evaluating long-term effects are required.

Abstract
BACKGROUND The human foetus typically needs to rotate when passing through the tight birth canal because of the complex shape of the pelvis. In most women, the upper part, or inlet, of the birth canal has a round or mediolaterally oval shape, which is considered ideal for parturition, but it is unknown why the lower part of the birth canal has a pronounced anteroposteriorly oval shape. RESULTS Here, we show that the shape of the lower birth canal affects the ability of the pelvic floor to resist the pressure exerted by the abdominal organs and the foetus. Based on a series of finite element analyses, we found that the highest deformation, stress, and strain occur in pelvic floors with a circular or mediolaterally oval shape, whereas an anteroposterior elongation increases pelvic floor stability. CONCLUSIONS This suggests that the anteroposterior oval outlet shape is an evolutionary adaptation for pelvic floor support. For the pelvic inlet, by contrast, it has long been assumed that the mediolateral dimension is constrained by the efficiency of upright locomotion. But we argue that the mediolateral elongation has evolved because of the limits on the anteroposterior diameter imposed by upright posture. We show that an anteroposteriorly deeper inlet would require greater pelvic tilt and lumbar lordosis, which compromises spine health and the stability of upright posture. These different requirements of the pelvic inlet and outlet likely have led to the complex shape of the pelvic canal and to the evolution of rotational birth characteristic of humans.

Abstract
OBJECTIVE To evaluate whether locally applied vaginal estrogen affects prolapse-associated complaints compared with placebo treatment in postmenopausal women prior to surgical prolapse repair. DESIGN Randomised, double-masked, placebo-controlled, multicentre study. SETTING Urogynaecology unit at the Medical University of Vienna and University Hospital of Tulln. POPULATION Postmenopausal women with symptomatic pelvic organ prolapse and planned surgical prolapse repair. METHODS Women were randomly assigned local estrogen cream or placebo cream 6 weeks preoperatively. MAIN OUTCOME MEASURES The primary outcome was differences in subjective prolapse-associated complaints after 6 weeks of treatment prior to surgery, assessed with the comprehensive German pelvic floor questionnaire. Secondary outcomes included differences in other pelvic floor-associated complaints (bladder, bowel or sexual function). RESULTS Out of 120 women randomised, 103 (86%) remained for the final analysis. After 6 weeks of treatment the prolapse domain score did not differ between the estrogen and the placebo groups (4.4 ± 0.19 versus 4.6 ± 0.19; mean difference, -0.21; 95% CI -0.74 to 0.33; P = 0.445). Multivariate analysis, including only women receiving the intervention, showed that none of the confounding factors modified the response to estradiol. CONCLUSIONS These results demonstrate that preoperative locally applied estrogen does not ameliorate prolapse-associated symptoms in postmenopausal women with symptomatic pelvic organ prolapse. TWEETABLE ABSTRACT Preoperative local estrogen does not ameliorate prolapse-associated symptoms in postmenopausal women with pelvic organ prolapse.

Low-Intensity Extracorporeal Shock Wave Therapy Promotes Bladder Regeneration and Improves Overactive Bladder Induced by Ovarian Hormone Deficiency from Rat Animal Model to Human Clinical Trial. Int J Mol Sci 2021; 22:ijms22179296.

Abstract
Postmenopausal women with ovary hormone deficiency (OHD) are subject to overactive bladder (OAB) symptoms. The present study attempted to elucidate whether low-intensity extracorporeal shock wave therapy (LiESWT) alters bladder angiogenesis, decreases inflammatory response, and ameliorates bladder hyperactivity to influence bladder function in OHD-induced OAB in human clinical trial and rat model. The ovariectomized (OVX) for 12 months Sprague–Dawley rat model mimicking the physiological condition of menopause was utilized to induce OAB and assess the potential therapeutic mechanism of LiESWT (0.12 mJ/mm2, 300 pulses, and 3 pulses/second). The randomized, single-blinded clinical trial was enrolled 58 participants to investigate the therapeutic efficacy of LiESWT (0.25 mJ/mm2, 3000 pulses, 3 pulses/second) on postmenopausal women with OAB. The results revealed that 8 weeks’ LiESWT inhibited interstitial fibrosis, promoted cell proliferation, enhanced angiogenesis protein expression, and elevated the protein phosphorylation of ErK1/2, P38, and Akt, leading to decreased urinary frequency, nocturia, urgency, urgency incontinence, and post-voided residual urine volume, but increased voided urine volume and the maximal flow rate of postmenopausal participants. In conclusion, LiESWT attenuated inflammatory responses, increased angiogenesis, and promoted proliferation and differentiation, thereby improved OAB symptoms, thereafter promoting social activity and the quality of life of postmenopausal participants.

Abstract
We developed biodegradable drug-eluting prolapse mats using solution-extrusion 3D printing and coaxial electrospinning techniques. The mats were composed of polycaprolactone (PCL) mesh and lidocaine-, estradiol-, metronidazole-, and connective tissue growth factor (CTGF)-incorporated poly(lactic-co-glycolic acid) (PLGA) nanofibers that mimic the structure of the natural extracellular matrix of most connective tissues. The mechanical properties of degradable prolapse membrane were assessed and compared to commercial non-degradable polypropylene knitted meshes clinically used for pelvic organ prolapse (POP) repair. The release behaviors of the drug-loaded hybrid degradable membranes were also characterized. The experimental results suggest that 3D-printed PCL meshes exhibited comparable strengths to commercial POP meshes and survived through 10,000 cycles of fatigue test without breakage. Hybrid PCL meshes/PLGA nanofibrous membranes provided a sustainable release of metronidazole, lidocaine, and estradiol for 4, 25, and 30 days, respectively, in vitro. The membranes further liberated high levels of CTGF for more than 30 days. The animal tests show that the mechanical property of PCL mesh decreased with time, mainly due to degradation of the polymers post-implantation. No adverse effect of the mesh/nanofibers was noted in the histological images. By adopting solution-extrusion 3D printing and coaxial electrospinning, degradable drug-eluting membranes can be fabricated for POP applications.

[PMID: 34200470 PMCID: PMC8201142 DOI: 10.3390/jcm10112531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 05/17/2021] [Accepted: 06/01/2021] [Indexed: 11/17/2022] Open
Abstract
The aim of this prospective randomized, double-masked, placebo-controlled, multicenter study was to analyze the surgeon’s individual assessment of tissue quality during pelvic floor surgery in postmenopausal women pre-treated with local estrogen therapy (LET) or placebo cream. Secondary outcomes included intraoperative and early postoperative course of the two study groups. Surgeons, blinded to patient’s preoperative treatment, completed an 8-item questionnaire after each prolapse surgery to assess tissue quality as well as surgical conditions. Our hypothesis was that there is no significant difference in individual surgical assessment of tissue quality between local estrogen or placebo pre-treatment. Multivariate logistic regression analysis was performed to identify independent risk factors for intra- or early postoperative complications. Out of 120 randomized women, 103 (86%) remained for final analysis. Surgeons assessed the tissue quality similarity in cases with or without LET, representing no statistically significant differences concerning tissue perfusion, tissue atrophy, tissue consistency, difficulty of dissection and regular pelvic anatomy. Regarding pre-treatment, the rating of the surgeon correlated significantly with LET (r = 0.043), meaning a correct assumption of the surgeon. Operative time, intraoperative blood loss, occurrence of intraoperative complications, total length of stay, frequent use of analgesics and rate of readmission did not significantly differ between LET and placebo pre-treatment. The rate of defined postoperative complications and use of antibiotics was significantly more frequent in patients without LET (p = 0.045 and p = 0.003). Tissue quality was similarly assessed in cases with or without local estrogen pre-treatment, but it seems that LET prior to prolapse surgery may improve vaginal health as well as tissue-healing processes, protecting these patients from early postoperative complications.

Abstract
RESUMO Incontinência urinária (IU) e disfunção sexual feminina (DSF) são disfunções que afetam a qualidade de vida. Com a mudança na pirâmide etária brasileira, a prevalência de tais disfunções tende a aumentar. O objetivo deste estudo foi estabelecer a relação entre a IU, a DSF e a contração muscular perineal em idosas ativas fisicamente. Trata-se de estudo transversal, do qual participaram 35 idosas ≥60 anos. Inicialmente foram aplicados a ficha diagnóstica e os questionários International Consultation on Incontinence Questionnaire - Short Form (ICIQ-UI-SF) e Female Sexual Function Index (FSFI). Em seguida foram avaliados os músculos do assoalho pélvico (MAP) por meio do toque vaginal, de acordo com o que propõe o esquema perfect. Entre as idosas, 20% apresentaram ambas as disfunções dos MAP. No total, 17 (48,6%) apresentavam IU e 16 (45,7%) DSF. Observou-se diferença significativa no número de partos vaginais (p=0,028) e no item rapidez do esquema perfect (p=0,033) entre as idosas com e sem DSF. Não houve diferença estatística entre os grupos com e sem IU. A análise apontou uma correlação inversamente proporcional entre a gravidade da IU e a função sexual nas idosas incontinentes (p=0,008; r=−0,622), de forma que, para cada aumento na gravidade da IU pelo ICIQ-SF, diminuiu-se 0,507 de função sexual avaliada pelo FSFI (p=0,034; r=0,516). Há uma associação entre IU e DSF em idosas fisicamente ativas. Algumas idosas apresentam ambas as disfunções dos MAP, apesar de serem ativas fisicamente. Dessa forma, é necessário reforçar a importância de avaliações minuciosas, da atividade física orientada e da atuação multiprofissional em saúde.

Abstract
AIM To compare urethral sphincter measurements in women with different urodynamic diagnoses using three-dimensional transperineal ultrasound (TPU). METHODS Women with lower urinary tract dysfunction having urodynamic studies (UDS) were prospectively recruited to this study. A detailed history and vaginal examination were conducted. Saline cystometry was performed and the women were divided into groups according to their urodynamic diagnosis, which were nondiagnostic urodynamics (NUDS), pure detrusor overactivity (PureDO), pure urodynamic stress incontinence (PureUSI) and mixed urinary incontinence (MUDS). Three-dimensional TPU was performed to measure total urethral sphincter volume, striated sphincter volume, core volume, sphincter length and maximum cross-sectional area. The ultrasound measurements were compared with the diagnostic urodynamics. RESULTS One hundred fifty women were included in the study. There were 37, 53, 22 and 38 women in the groups of NUDS, PureDO, PureUSI and MUDS respectively. The average striated sphincter volumes in these groups were 1.84 ml, 2.24 ml, 1.32 ml and 1.98 ml respectively. There was no difference in average age, body mass index or presence of prolapse in these groups. All measurements were larger in the PureDO and smaller in the PureUSI group compared with the NUDS group. The measurements in the MUDS group were larger than in the NUDS group and smaller than in the PureDO group but this difference was not statistically significant. CONCLUSION The urethral sphincter of women with PureDO is larger than in women with PureUSI. The value in women with MUDS was between the two. The size of the urethral sphincter appears to be related to the pathophysiology.

Abstract
INTRODUCTION AND HYPOTHESIS The current study is aimed at characterizing the association between pelvic floor disorder symptoms and bone strength reflecting a potential connective tissue pathophysiology in postmenopausal women. METHODS A cross-sectional study was conducted in postmenopausal women undergoing osteoporosis evaluation from 2007 to 2010. Urinary incontinence (UI) was defined as urinary leakage ≥2-3 times/week. UI types were defined using the 3 Incontinence Questionnaire. Fecal incontinence was defined as stool leakage ≥1/month, and pelvic organ prolapse as a positive response to "Do you have a bulge or something falling out that you can see or feel in your vaginal area?" Bone quality and quantity were assessed using the trabecular bone score (TBS) and bone mineral density respectively: bone strength was defined by combined quality/quantity index, low strength being equivalent to moderate to severe fracture risk; low quality as TBS ≤ 1.31; low quantity by T-score <-1 or on osteoporosis medication. RESULTS Of 681 subjects, 262 had low bone strength whereas 419 were normal using the combined quality/quantity bone assessment. Characteristics were similar except for age (low bone strength: 69.0 ± 8.2 vs normal: 65.0 ± 7.1, p < 0.01) and smoking (8.8% vs 3.3%, p < 0.01). Low bone strength was associated with any UI (adjusted odds ratio [aOR]: 1.48, 1.05-2.10), stress (aOR: 1.53, 1.06-2.21), and mixed (aOR :1.45, 1.02-2.05). Women with low bone quality had increased odds of UI (any, urgency, mixed), whereas none of the pelvic floor disorder symptoms was associated with low bone quantity. CONCLUSIONS Low bone strength defined by a combined quantity/quality index, as well as low bone quality alone, were associated with increased risk of UI.

Abstract
Overactive bladder syndrome (OAB) is common chronic medical condition which has a major impact on health and quality of life. This condition affects daily activities, performance and social function and servers as a real challenge for care giver in attempt to treat patients' symptoms. Given the fact that therapy rarely results in cure and the high rate of discontinuation, treatment should primarily aim to reduce social and psychological disability. The purpose of our update is to give an overview of recent data regarding OAB, and to provide practical clinical tools for evaluation and management of OAB syndrome according to current literature evidence.
