Effect of sacrospinous hysteropexy with graft vs vaginal hysterectomy with uterosacral ligament suspension on treatment failure in women with uterovaginal prolapse: 5-year results of a randomized clinical trial.

BACKGROUND: Vaginal hysterectomy with suture apical suspension is commonly performed for uterovaginal prolapse. Sacrospinous hysteropexy with graft (vaginal mesh hysteropexy) is an alternative, although in 2019 the Food and Drug Administration removed this mesh product from the United States market. OBJECTIVE: Our objective was to compare the efficacy and adverse events of these 2 procedures. STUDY DESIGN: At 9 clinical sites in the United States National Institutes of Health and National Institute of Child Health and Human Development Pelvic Floor Disorders Network, 183 postmenopausal women requesting vaginal surgery for symptomatic uterovaginal prolapse were enrolled in a multisite randomized superiority clinical trial, comparing a sacrospinous hysteropexy with graft (hysteropexy) with a vaginal hysterectomy with uterosacral ligament suspension (hysterectomy). Participants consented to remain masked to treatment assignment for the study duration. Study visits were conducted at 6-month intervals through 60 months. The primary treatment failure composite outcome (retreatment of prolapse, prolapse beyond the hymen, or prolapse symptoms) was evaluated with survival modeling. Secondary outcomes included complications or adverse events, individual anatomic measures of the pelvic organ prolapse quantification examination, and presence, severity, and impact and bother of prolapse, urinary, bowel, and pain symptoms as measured by validated questionnaires. The 3-year published results suggested better primary outcomes with sacrospinous hysteropexy with graft, but the differences were not statistically significant (P=.06). This study reports the 5-year outcomes. RESULTS: A total of 183 women with a mean age of 66 years were randomized between April 2013 and February 2015; 93 were randomized to hysteropexy and 90 were randomized to hysterectomy. Notably, 175 were included in the trial, and 156 (89%) completed the 5-year follow-up. The primary outcome showed fewer failures for hysteropexy than hysterectomy through 5 years (adjusted hazard ratio, 0.58; 95% confidence interval, 0.36-0.94; P=.03), with failure rates of 37% vs 54%, respectively, resulting in a difference of -18% (95% confidence interval, -33% to -3%) at 5 years. With the exception of the Urogenital Distress Inventory, no group differences were demonstrated in patient-reported pelvic floor symptoms, prolapse symptoms, bowel function symptoms, general quality of life, body image, or pelvic pain. At their last visit through 5 years, 70% of participants (129 of 183) reported they remained masked to their treatment with no difference in masking between groups. Adverse events for hysteropexy vs hysterectomy included mesh exposure (8% vs 0%), granulation tissue after 12 weeks (1% vs 12%), and suture exposure after 12 weeks (3% vs 21%), respectively. CONCLUSION: Among women with symptomatic uterovaginal prolapse undergoing vaginal surgery, sacrospinous hysteropexy with graft resulted in a lower composite failure rate than vaginal hysterectomy through 5 years. There were no meaningful differences in patient-reported outcomes between groups. Our results suggest that this vaginal mesh hysteropexy procedure should be made available to patients.

A cross-sectional study on pelvic floor symptoms in women living with Female Genital Mutilation/Cutting.

BACKGROUND: Female Genital Mutilation/Cutting (FGM/C) concerns over 200 million women and girls worldwide and is associated with obstetric trauma and long-term urogynaecological and psychosexual complications that are often under-investigated and undertreated. The aim of this study was to assess the pelvic floor distress and the impact of pelvic floor and psychosexual symptoms among migrant women with different types of FGM/C. METHODS: This cross-sectional study was conducted between April 2016 and January 2019 at the Division of Gynaecology of the Geneva University Hospitals. The participants were interviewed on socio-demographic and background information, underwent a systematic gynaecological examination to assess the presence and type of FGM/C and eventual Pelvic Organ Prolapse (POP), and completed six validated questionnaires on pelvic floor and psychosexual symptoms (PFDI-20 and PFIQ7 on pelvic floor distress and impact, FISI and WCS on faecal incontinence and constipation, PISQ-IR and FGSIS on sexual function and genital self-image). The participants' scores were compared with scores of uncut women available from the literature. The association between selected variables and higher scores for distress and impact of pelvic floor symptoms was assessed using univariate and multivariable linear regression models. RESULTS: 124 women with a mean age of 31.5 (± 7.5), mostly with a normal BMI, and with no significant POP were included. PFDI-20 and PFIQ-7 mean (± SD) scores were of 49.5 (± 52.0) and 40.7 (± 53.6) respectively. In comparison with the available literature, the participants' scores were lower than those of uncut women with pelvic floor dysfunction but higher than those of uncut women without such disorders. Past violent events other than FGM/C and forced or arranged marriage, age at FGM/C of more than 10, a period of staying in Switzerland of less than 6 months, and nulliparity were significantly associated with higher scores for distress and impact of pelvic floor symptoms, independently of known risk factors such as age, weight, ongoing pregnancy and history of episiotomy. CONCLUSIONS: Women with various types of FGM/C, without POP, can suffer from pelvic floor symptoms responsible for distress and impact on their daily life. TRIAL REGISTRATION: The study protocol was approved by the Swiss Ethics Committee on research involving humans (protocol n°15-224).

Association between adjuvant posterior repair and success of native tissue apical suspension.

BACKGROUND: Posterior repairs and perineorrhaphies are often performed in prolapse surgery to reduce the size of the genital hiatus. The benefit of an adjuvant posterior repair at the time of sacrospinous ligament fixation or uterosacral ligament suspension is unknown. OBJECTIVE: We aimed to determine whether an adjuvant posterior repair at transvaginal apical suspension is associated with improved surgical success. MATERIALS AND METHODS: This secondary analysis of Operations and Pelvic Muscle Training in the Management of Apical Support Loss (OPTIMAL) trial compared 24-month outcomes in 190 participants who had a posterior repair (posterior repair group) and 184 who did not (no posterior repair group) at the time of sacrospinous ligament fixation or uterosacral ligament suspension. Concomitant posterior repair was performed at the surgeon's discretion. Primary composite outcome of "surgical success" was defined as no prolapse beyond the hymen, point C ≤ -2/3 total vaginal length, no bothersome bulge symptoms, and no retreatment at 24 months. The individual components were secondary outcomes. Propensity score methods were used to build models that balanced posterior repair group and the no posterior repair group for ethnographic factors and preoperative Pelvic Organ Prolapse Quantification values. Adjusted odds ratios were calculated to predict surgical success based on the performance of a posterior repair. Groups were also compared with unadjusted χ2 analyses. An unadjusted probability curve was created for surgical success as predicted by preoperative genital hiatus. RESULTS: Women in the posterior repair group were less likely to be Hispanic or Latina, and were more likely to have had a prior hysterectomy and to be on estrogen therapy. The groups did not differ with respect to preoperative Pelvic Organ Prolapse Quantification stage; however, subjects in the posterior repair group had significantly greater preoperative posterior wall prolapse. There were no group differences in surgical success using propensity score methods (66.7% posterior repair vs 62.0% no posterior repair; adjusted odds ratio, 1.07; 95% confidence interval, 0.56-2.07; P = 0.83) or unadjusted test (66.2% posterior repair vs 61.7% no posterior repair; P = 0.47). Individual outcome measures of prolapse recurrence (bothersome bulge symptoms, prolapse beyond the hymen, or retreatment for prolapse) also did not differ by group. Similarly, there were no differences between groups in anatomic outcomes of any individual compartment (anterior, apical, or posterior) at 24 months. There was high variation in performance of posterior repair by surgeon (interquartile range, 15-79%). The unadjusted probability of overall success at 24 months, regardless of posterior repair, decreased with increasing genital hiatus, such that a genital hiatus of 4.5 cm was associated with 65.8% success (95% confidence interval, 60.1-71.1%). CONCLUSION: Concomitant posterior repair at sacrospinous ligament fixation or uterosacral ligament suspension was not associated with surgical success after adjusting for baseline covariates using propensity scores or unadjusted comparison. Posterior repair may not compensate for the pathophysiology that leads to enlarged preoperative genital hiatus, which remains prognostic of prolapse recurrence.

Long-term Anatomical and Functional Results of Robot-Assisted Pelvic Floor Surgery for the Management of Multicompartment Prolapse: A Prospective Study.

BACKGROUND: Long-term data on robot-assisted sacrocolporectopexy for the treatment of multicompartment pelvic organ prolapse are scarce. With the rising prevalence of prolapse and increasing surgical repair, it is essential to evaluate long-term results. OBJECTIVE: This study aimed to evaluate long-term functional and anatomic outcomes after sacrocolporectopexy. DESIGN: This is a prospective, observational cohort study. SETTINGS: This study was conducted at a teaching hospital with tertiary referral function for patients with gynecological/rectal prolapse. PATIENTS: All patients undergoing robot-assisted sacrocolporectopexy from 2011 to 2012 were included. INTERVENTION: Robot-assisted sacrocolporectopexy was performed. MAIN OUTCOME MEASURES: The primary outcome was the anatomic cure rate after 1 and 4 years, defined as simplified pelvic organ prolapse quantification stage 1 vaginal apical prolapse and no external rectal prolapse or internal rectal prolapse present. Kaplan-Meier curves were used for determination of recurrence-free intervals. Secondary outcomes were functional pelvic floor symptoms (symptoms of bulge, obstructed defecation, fecal incontinence, urogenital distress inventory) and quality of life (Pelvic Floor Impact Questionnaire). RESULTS: Fifty-three patients were included. After 12 and 48 months, the recurrence-free intervals based on Kaplan-Meier estimates were 100% and 90%. In total, there were 10 recurrences: 2 apical and 8 internal rectal prolapses. Symptoms of bulge (94%-12%; p < 0.0005), fecal incontinence (62%-32%; p < 0.0005), obstructed defecation (59%-24%; p = 0.008), and median Pelvic Floor Impact Questionnaire scores (124-5; p = 0.022) improved significantly at final follow-up. Median urogenital distress inventory scores showed improvement after 1 year (30-13; p = 0.021). LIMITATIONS: This was an observational, single-center study with selective postoperative imaging. CONCLUSIONS: Ninety percent of patients were recurrence free 48 months after robot-assisted sacrocolporectopexy. Symptoms of vaginal bulge, quality of life, constipation, and fecal incontinence improved significantly. However, a subgroup of patients showed persistent bowel complaints that underlie the complexity of multicompartment prolapse. See Video Abstract at http://links.lww.com/DCR/B265.

Mesh inlay, mesh kit or native tissue repair for women having repeat anterior or posterior prolapse surgery: randomised controlled trial (PROSPECT).

OBJECTIVE: To compare standard (native tissue) repair with synthetic mesh inlays or mesh kits. DESIGN: Randomised controlled trial. SETTING: Thirty-three UK hospitals. POPULATION: Women having surgery for recurrent prolapse. METHODS: Women recruited using remote randomisation. MAIN OUTCOME MEASURES: Prolapse symptoms, condition-specific quality-of-life and serious adverse effects. RESULTS: A Mean Pelvic Organ Prolapse Symptom Score at 1 year was similar for each comparison (standard 6.6 versus mesh inlay 6.1, mean difference [MD] -0.41, 95% CI -2.92 to 2.11: standard 6.6 versus mesh kit 5.9, MD -1.21 , 95% CI -4.13 to 1.72) but the confidence intervals did not exclude a minimally important clinical difference. There was no evidence of difference in any other outcome measure at 1 or 2 years. Serious adverse events, excluding mesh exposure, were similar at 1 year (standard 7/55 [13%] versus mesh inlay 5/52 [10%], risk ratio [RR] 1.05 [0.66-1.68]: standard 3/25 [12%] versus mesh kit 3/46 [7%], RR 0.49 [0.11-2.16]). Cumulative mesh exposure rates over 2 years were 7/52 (13%) in the mesh inlay arm, of whom four women required surgical revision; and 4/46 in the mesh kit arm (9%), of whom two required surgical revision. CONCLUSIONS: We did not find evidence of a difference in terms of prolapse symptoms from the use of mesh inlays or mesh kits in women undergoing repeat prolapse surgery. Although the sample size was too small to be conclusive, the results provide a substantive contribution to future meta-analysis. TWEETABLE ABSTRACT: There is not enough evidence to support use of synthetic mesh inlay or mesh kits for repeat prolapse surgery.

Prevalence, survival and subsequent fertility of dairy and beef cows with uterine prolapse.

The aim of this study was to evaluate the prevalence of uterine prolapse in cows and assess its effects on survival and subsequent fertility. Of 33,450 calving cows considered retrospectively, 216 (0.6%) developed uterine prolapse. A higher prevalence was found in beef cows (n = 57/5,700 cows, 1%) compared to dairy cows (n = 157/27,750 cows, 0.6%). Treatment consisted of cleaning and replacing the uterus with local administration of antibiotics, and applying a harness for uterine containment. The recovery rate was 81.9% (n = 177), similar in dairy (n = 129; 81.1%) and beef (n = 48; 84.2%) cows. Of the 216 cows with uterine prolapse, 18 (8.3%) died before or immediately after treatment; 21 cows (9.7%) were voluntarily culled for economic reasons (low milk yield, low fertility, insufficient weight gain). All recovered dairy cows were artificially inseminated with semen of proven fertility after a voluntary waiting period of 50 days; the beef cows were naturally mated. Among the 172 inseminated/mated cows, 84.7% (n = 150) became pregnant (83.7% dairy cows, 87.5% beef cows), while 15.2% (n = 27) did not conceive. Recurrence of uterine prolapse at subsequent calvings was recorded in one dairy cow. Based upon the data presented here, treated cows with uterine prolapse showed high chances of survival and conception, and a low risk of recurrence.

Long-term outcome (5-10 years) after non absorbable mesh insertion compared to partially absorbable mesh insertion for anterior vaginal wall prolapse repair.

OBJECTIVE: To evaluate long-term (5-10 years) outcomes of Minimally Invasive Surgical (MIS) kit insertion with Prolift® (non-absorbable) mesh compared to the use of Prolift M® (partially absorbable), for anterior vaginal wall prolapse repair. STUDY DESIGN: In this retrospective study we compared women undergoing MIS kit Prolift ® insertion (n=90) vs. Prolift M® insertion (n=79) for anterior vaginal wall prolapse repair between 2006 and 2012 at our Institution. A number of 169 women fulfilled the inclusion criteria and were included in the study. RESULTS: During the study period 128 women (76%) completed full follow-up; of them 58 (73%) following MIS kit Prolift® insertion, and 70 (88%) following MIS kit ProliftM® insertion. There was no signifi cant difference between the Prolift® and Prolift M® regarding parity (3.04 vs. 2.88, p=0.506), presence of hypertension (24.1% vs. 39.1%, p=0.088), diabetes mellitus (3.4% vs. 11.6%, p=0.109), or urinary stress incontinence (39.7% vs. 47.1%, p=0.475). All participants had been diagnosed with POP grade 3 or 4 before the procedure. No significant complications during the procedure or postoperative period were identified in the study groups. The follow-up period was at least five years in duration for both groups. Both groups were comparable according to questionnaires focused on function and satisfaction. CONCLUSION: Patients undergoing MIS kit Prolift® and Prolift M® insertion for anterior vaginal wall prolapse repair had comparable early and late postoperative outcomes. No differences in patient's function and satisfaction between the two groups were identified. According to our fi ndings, there is no superiority to either of the two studied mesh devices.

The predictive value of demonstrable stress incontinence during basic office evaluation and urodynamics in women without symptomatic urinary incontinence undergoing vaginal prolapse surgery.

AIMS: Women with pelvic organ prolapse without symptoms of urinary incontinence (UI) might demonstrate stress urinary incontinence (SUI) with or without prolapse reduction. We aimed to determine the value of demonstrable SUI during basic office evaluation or urodynamics in predicting SUI after vaginal prolapse repair in these women. METHODS: Women included in the CUPIDO trials without bothersome UI or UI more than once a week were eligible if they had undergone prolapse repair without incontinence surgery. The diagnostic and predictive value of demonstrable SUI was studied for postoperative SUI (POSUI). POSUI was defined as bothersome SUI at 1-year follow-up or treatment for SUI in the first postoperative year. RESULTS: In 45% (77/173) of the included women urodynamics was performed. In 19% (32/172) SUI was demonstrated with basic office evaluation, against 29% (22/77) with urodynamics. Nine percent (16/172) developed POSUI, six women underwent surgery for de novo SUI. Women with demonstrable SUI were more at risk to face POSUI: twenty-eight percent versus five percent (Diagnostic Odds Ratio: 7; 95%CI 3-22). Urodynamics predicted one more woman having POSUI, but all women who underwent treatment for de novo SUI showed SUI during basic office evaluation. Test performance did not improved with the adding of urodynamics. CONCLUSIONS: The predictive value of demonstrable SUI in symptomatically continent women undergoing vaginal prolapse repair is limited. Urodynamics added no value. The twenty-eight percent POSUI risk must be balanced against the increased complication risk if a prophylactic midurethral sling is considered.

Pelvic floor muscle weakness: a risk factor for anterior vaginal wall prolapse recurrence.

INTRODUCTION AND HYPOTHESIS: Native tissue vaginal repairs are associated with relatively high levels of recurrence. Systematic reviews have noted that preoperative pelvic floor muscle strength was associated with increased risk of recurrence in the short term. METHODS: This is a retrospective review of patients who underwent a primary reconstructive surgery for anterior compartment vaginal prolapse between 2001 and 2015. Patients were divided into "absent," "weak" and "good" preoperative PFM strength (aPFM, wPFM and gPFM, respectively) based on a modified Oxford scale. Failure rates were determined by a composite of subjective and objective anatomic outcomes. Subjects who underwent re-operations or procedures for recurrent prolapse of the anterior compartment were considered failures. A p value < 0.05 was considered statistically significant. RESULTS: Two hundred ninety-nine patients were included. The aPFM (n = 36), wPFM (n = 115) and gPFM (n = 148) groups had similar descriptive statistics, except subjects in the aPFM and wPFM groups were significantly older than the gPFM group (p = 0.008). All groups underwent similar reconstructive surgeries. Average length of follow-up of 143.9 weeks (41 to 717 weeks) was similar among the three groups (p = 0.472). For the primary outcome of composite failure, aPFM had significantly more anterior vaginal wall recurrences than both the wPFM and gPFM groups, 13.89% vs. 3.48% and 4.05%, respectively (p = 0.033). CONCLUSIONS: Patients with preoperative absent pelvic floor muscle strength (nonfunctioning PFM) had a significantly higher anterior vaginal wall recurrence rate than those with weak or good pelvic floor muscle strength.

Effects of Pneumoperitoneum and the Steep Trendelenburg Position on Heart Rate Variability and Cerebral Oxygenation during Robotic Sacrocolpopexy.

STUDY OBJECTIVE: The aim of this study was to investigate how steep Trendelenburg positioning with pneumoperitoneum modifies brain oxygenation and autonomic nervous system modulation of heart rate variability during robotic sacrocolpopexy. DESIGN: Prospective study (Canadian Task Force classification III). SETTING: Rambam Health Care Campus. PATIENTS: Eighteen women who underwent robotic sacrocolpopexy for treatment of uterovaginal or vaginal apical prolapse. INTERVENTIONS: Robotic sacrocolpopexy. MEASUREMENTS AND MAIN RESULTS: A 5-minute computerized electrocardiogram, cerebral O2 saturation (cSO2), systemic O2 saturation, heart rate (HR), diastolic blood pressure (BP), systolic BP, and end-tidal CO2 tension were recorded immediately after anesthesia induction (baseline phase) and after alterations in positioning and in intra-abdominal pressure. HR variability was assessed in time and frequency domains. Cerebral oxygenation was measured by the technology of near-infrared spectrometry. cSO2 at baseline was 73% ± 9%, with minor and insignificant elevation during the operation. Mean HR decreased significantly when the steep Trendelenburg position was implemented (66 ± 10 vs 55 ± 9 bpm, p < .05) and returned gradually to baseline with advancement of the operation and the decrease in intra-abdominal pressure. Concomitant with this decrease, the power of both arms of the autonomic nervous system increased significantly (2.8 ± .8 vs 3.3 ± .9 ms2/Hz and 2.5 ± 1.2 vs 3.2 ± .9 ms2/Hz, respectively, p < .05). All these effects occurred without any significant shifts in systolic or diastolic BP or in systemic or cerebral oxygenation. CONCLUSION: This study supports the safety of robotic sacrocolpopexy performed with steep Trendelenburg positioning with pneumoperitoneum. Only minor alterations were observed in cerebral oxygenation and autonomic perturbations, which did not cause clinically significant alterations in HR rate and HR variability.

[Outcomes of ER:YAG LASER treatment of stress urinary incontinence in women].

AIM: To evaluate the effectiveness of a new method of treatment for stress urinary incontinence in women using an ER: YAG laser in SMOOTH mode and investigate pathophysiological and pathomorphological changes induced by erbium laser. MATERIALS AND METHODS: This study comprised 98 women aged 37-63 years, who between 2014 and 2016 were diagnosed with SUI (type 1 and 2a, 2b) and grade 0-2 vaginal prolapse. The treatment was performed with a 2940 nm Er:YAG laser (Fotona, Slovenia) using a SMOOTH mode. Clinical assessment included PFIQ-7 and PISQ-12 questionnaires, uroflowmetry, laser Doppler flowmetry and biopsy of the anterior vaginal wall. The examination was carried out at baseline and 1-2 months after the treatment. RESULTS: The effectiveness of treatment was 73%. There was no deterioration after the procedure. Analysis of PFIQ-7 and PISQ-12 questionnaires showed that patients with mild incontinence had the greatest difference between pre- and posttreatment results. Uroflowmetry parameters improved in a majority of patients. Results of laser Doppler flowmetry demonstrated the improvement of blood flow in the microvascular bed. An important feature of the vaginal biopsy after laser exposure was an increase in neoangiogenesis. DISCUSSION: The findings of questionnaires and clinical evaluation of patients with SUI and vaginal prolapse before and after treatment with Er: YAG laser showed high therapeutic effectiveness of this treatment modality. CONCLUSION: Clinical effectiveness of ER: YAG laser in SMOOTH mode was 73%. Patients with type 1 and 2a SUI and mild or moderate incontinence have the best prognosis after treatment with this method.

Temporal relationship between posterior vaginal prolapse and defecatory symptoms.

BACKGROUND: Posterior vaginal prolapse is thought to cause difficult defecation and splinting for bowel movements. However, the temporal relationship between difficult defecation and prolapse is unknown. Does posterior vaginal prolapse lead to the development of defecation symptoms? Conversely, does difficult defecation lead to posterior prolapse? This prospective longitudinal study offered an opportunity to study these unanswered questions. OBJECTIVE: We sought to investigate the following questions: (1) Are symptoms of difficult defecation more likely to develop (and less likely to resolve) among women with posterior vaginal prolapse? (2) Is posterior vaginal prolapse more likely to develop among women who complain of difficult defecation? STUDY DESIGN: In this longitudinal study, parous women were assessed annually for defecatory symptoms (Epidemiology of Prolapse and Incontinence Questionnaire) and pelvic organ support (POP-Q examination). The unit of analysis for this study was a visit-pair (2 sequential visits from any participant). We created logistic regression models for symptom onset among those women who were symptom-free at the index visit and for symptom resolution among those women who had symptoms at the index visit. To investigate the change in posterior vaginal support (assessed at point Bp) as a function of symptom status, we created a standard regression model that controlled for Bp at the index visit for each visit-pair. RESULTS: We derived 3888 visit-pairs from 1223 women (each completed 2-7 annual visits). At the index visit, 1143 women (29%) reported difficulty with bowel movements, and 643 women (17%) reported splinting for bowel movements. Posterior vaginal prolapse (Bp≥0) was observed among 80 women (2%). Among those women without symptoms, posterior vaginal prolapse did not significantly increase the odds that defecatory symptoms would develop (difficult bowel movements, P=.378; splinting, P=.765). In contrast, among those with defecatory symptoms, posterior vaginal prolapse reduced the probability of symptom resolution (difficult bowel movements, P<.001; splinting, P=.162). The mean rate of change in posterior wall support was +0.13 cm. Among women without posterior vaginal prolapse, the presence of defecatory symptoms at the index visit did not have an effect on changes in Bp over time; however, among those with posterior vaginal prolapse (Bp≥0), defecatory symptoms were associated with more rapid worsening of posterior support (difficulty with bowel movements, P=.005; splinting, P=.057). CONCLUSION: Posterior vaginal prolapse did not increase the odds that new defecatory symptoms would develop among asymptomatic women but did increase the probability that defecatory symptoms would persist over time. Furthermore, among those women with established posterior vaginal prolapse, defecatory symptoms were associated with more rapid worsening of posterior vaginal wall descent.

Intraoperative cervix location and apical support stiffness in women with and without pelvic organ prolapse.

BACKGROUND: It is unknown how initial cervix location and cervical support resistance to traction, which we term "apical support stiffness," compare in women with different patterns of pelvic organ support. Defining a normal range of apical support stiffness is important to better understand the pathophysiology of apical support loss. OBJECTIVE: The aims of our study were to determine whether: (1) women with normal apical support on clinic Pelvic Organ Prolapse Quantification, but with vaginal wall prolapse (cystocele and/or rectocele), have the same intraoperative cervix location and apical support stiffness as women with normal pelvic support; and (2) all women with apical prolapse have abnormal intraoperative cervix location and apical support stiffness. A third objective was to identify clinical and biomechanical factors independently associated with clinic Pelvic Organ Prolapse Quantification point C. STUDY DESIGN: We conducted an observational study of women with a full spectrum of pelvic organ support scheduled to undergo gynecologic surgery. All women underwent a preoperative clinic examination, including Pelvic Organ Prolapse Quantification. Cervix starting location and the resistance (stiffness) of its supports to being moved steadily in the direction of a traction force that increased from 0-18 N was measured intraoperatively using a computer-controlled servoactuator device. Women were divided into 3 groups for analysis according to their pelvic support as classified using the clinic Pelvic Organ Prolapse Quantification: (1) "normal/normal" was women with normal apical (C < -5 cm) and vaginal (Ba and Bp < 0 cm) support; (2) normal/prolapse had normal apical support (C < -5 cm) but prolapse of the anterior or posterior vaginal walls (Ba and/or Bp ≥ 0 cm); and (3) prolapse/prolapse had both apical and vaginal wall prolapse (C > -5 cm and Ba and/or Bp ≥ 0 cm). Demographics, intraoperative cervix locations, and apical support stiffness values were then compared. Normal range of cervix location during clinic examination and operative testing was defined by the total range of values observed in the normal/normal group. The proportion of women in each group with cervix locations within and outside the normal range was determined. Linear regression was performed to identify variables independently associated with clinic Pelvic Organ Prolapse Quantification point C. RESULTS: In all, 52 women were included: 14 in the normal/normal group, 11 in the normal/prolapse group, and 27 in the prolapse/prolapse group. At 1 N of traction force in the operating room, 50% of women in the normal/prolapse group had cervix locations outside the normal range while 10% had apical support stiffness outside the normal range. Of women in the prolapse/prolapse group, 81% had cervix locations outside the normal range and 8% had apical support stiffness outside the normal range. Similar results for cervix locations were observed at 18 N of traction force; however the proportion of women with apical support stiffness outside the normal range increased to 50% in the normal/prolapse group and 59% in the prolapse/prolapse group. The prolapse/prolapse group had statistically lower apical support stiffness compared to the normal/normal group with increased traction from 1-18 N (0.47 ± 0.18 N/mm vs 0.63 ± 0.20 N/mm, P = .006), but all other comparisons were nonsignificant. After controlling for age, parity, body mass index, and apical support stiffness, cervix location at 1 N traction force remained an independent predictor of clinic Pelvic Organ Prolapse Quantification point C, but only in the prolapse/prolapse group. CONCLUSION: Approximately 50% of women with cystocele and/or rectocele but normal apical support in the clinic had cervix locations outside the normal range under intraoperative traction, while 19% of women with uterine prolapse had normal apical support. Identifying women whose apical support falls outside a defined normal range may be a more accurate way to identify those who truly need a hysterectomy and/or an apical support procedure and to spare those who do not.

Exploring biomechanical methods to study the human vaginal wall.

AIMS: To critically review studies of the biomechanical properties of connective tissue in the normal and prolapsed human vaginal wall and to identify criteria that are suitable for in vivo measurements which could improve patient management. METHODS: This review covers past and current ex vivo and in vivo instrumentation and analytical methods related to the elastic and viscoelastic properties of vaginal wall connective tissues. RESULTS: Classical methods, including digital evaluation of the vagina, histological and biomechanical studies of fresh and frozen-thawed extracts, and biomechanical cadaveric tissue studies have important limitations and have yielded inconsistent results. Newer biomechanical methods may resolve these inconsistencies. One of the more promising is transient, vacuum-induced tissue expansion and relaxation, via cutometer-like devices. The technique permits noninvasive observation, applicable to longitudinal studies of patients. In vivo and ex vivo biomechanical methods may better match vaginal wall tissue properties to help with the design of surgical mesh materials, thus improving surgical support and healing. CONCLUSION: Methods have been identified to characterize the in vivo biomechanical behavior of the prolapsing vagina which may serve to advance the care of affected women. Neurourol.

Short-term outcomes of laparoscopic ventral rectopexy for obstructed defecation in patients with overt pelvic structural abnormalities-a Chinese pilot study.

AIM: As laparoscopic ventral rectopexy (LVR) gained increasing popularity in the past decade, studies from non-western area remain rare. The aim of this pilot study is to evaluate the efficacy and safety of LVR for obstructed defecation (OD) in Chinese patients with overt pelvic structural abnormalities. METHODS: A series of 19 consecutive patients is presented undergoing LVR for OD. All patients showed various forms of pelvic structural abnormalities which were verified by dynamic defecography exam. Data was prospectively recorded and the functional outcomes were evaluated using the Cleveland Clinic Constipation Score (CCCS) and Patients Assessment of Constipation Quality of Life Score (PAC-QoL). RESULTS: Pelvic structural abnormalities of the 19 patients included external rectal prolapse (ER) in 10.5% (2/19), high grade internal rectal prolapse (IR) in 57.8% (11/19), rectocele in 52.6% (10/19), enterocele in 15.7% (3/19), cystocele/vaginal prolapse in 15.7 (3/19), descending perineum (DP) in 63.5% (12/19). 89.4% patients (17/19) showed at least two co-existed abnormalities and 15.7% (3/19) showed multicompartmental abnormalities. The mean follow-up was 9 months (range 1-18). No mesh-related complication was observed. At last available follow-up (LAFU), improvement of OD symptom was observed in 15 (78.9%) patients, the mean scores of CCCS decreased from 17 to 10 (p < 0.05), all four subsets of PAC-QoL scores improved, and three of them (physical discomfort, worries and concerns, satisfaction) showed statistical significance (p < 0.05). CONCLUSION: Laparoscopic ventral rectopexy appears to be a safe and effective procedure for obstructed defecation in Chinese patients with overt pelvic structural abnormalities in short-term follow-up.

Clinical impact of bowel symptoms in women with pelvic floor disorders.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate the correlations between the POP-Q Bp point and the perineal body (Pb) and genital hiatus (Gh) measurements and constipation, anal incontinence, severity of symptoms and quality of life. METHODS: The patients were distributed into two groups according to the posterior vaginal wall Bp point: one group with Bp ≤-1 (without posterior vaginal wall prolapse, control group) and the other group with Bp ≥0 (with posterior vaginal wall prolapse, case group). Demographic data, defecatory dysfunction and SF-36 scores were compared between the groups. Correlations between severity of posterior prolapse (Bp, Gh, Pb and Gh + Pb) and severity of bowel symptoms were also calculated. RESULTS: A total of 613 women were evaluated, of whom 174 were included, 69 (39.7%) in the control group and 105 (60.3%) in the case group. The groups were similar in terms of anal incontinence, fecal urgency and/or constipation. There was no correlation between the severity of constipation and anal incontinence according to the Wexner score, and the severity of posterior vaginal wall prolapse measured in terms of point Bp. There were, however, statistically significant differences in Pb, Gh and Gh + Pb between the groups. The Pb and Gh + Pb measurements were positively correlated with symptoms of constipation, as well as with the scores of some SF-36 domains, but were not correlated with anal incontinence. CONCLUSIONS: These results suggest that the severity of posterior vaginal wall prolapse is not correlated with constipation or anal incontinence, but Pb and Gh + Pb measurements are correlated with constipation and SF-36 scores.

Traction force needed to reproduce physiologically observed uterine movement: technique development, feasibility assessment, and preliminary findings.

INTRODUCTION AND HYPOTHESIS: This study aimed to describe a novel strategy to determine the traction forces needed to reproduce physiologic uterine displacement in women with and without prolapse. METHODS: Participants underwent dynamic stress magnetic resonance imaging (MRI) testing as part of a study examining apical uterine support. Physiologic uterine displacement was determined by analyzing uterine location in images taken at rest and at maximal Valsalva. Force-displacement curves were calculated based on intraoperative cervical traction testing. The intraoperative force required to achieve the uterine displacement measured during MRI was then estimated from these curves. Women were categorized into three groups based on pelvic organ support: group 1 (normal apical and vaginal support), group 2 (normal apical support but vaginal prolapse present), and group 3 (apical prolapse). RESULTS: Data from 19 women were analyzed: five in group 1, five in group 2, and nine in group 3. Groups were similar in terms of age, body mass index (BMI), and parity. Median operating room (OR) force required for uterine displacement measured during MRI was 0.8 N [interquartile range (IQR) 0.62-3.22], and apical ligament stiffness determined using MRI uterine displacement was 0.04 N/mm (IQR 0.02-0.08); differences between groups were nonsignificant. Uterine locations determined at rest and during maximal traction were lower in the OR compared with MRI in all groups. CONCLUSIONS: Using this investigative strategy, we determined that only 0.8 N of traction force in the OR was required to achieve maximal physiologic uterine displacement seen during dynamic (maximal Valsalva) MRI testing, regardless of the presence or absence of prolapse.

[Value of pudendal nerve stimulation for predicting the stress urinary incontinence following pelvic prolapse surgery].

OBJECTIVE: To seek the predictive value of pudendal nerve function that need preventive anti-incontinence surgery at the same time following pelvic prolapse surgery in severe pelvic organ prolapse (POP) patients. METHODS: Seventy women completed this study from January 2014 to June 2015 in Fuzhou General Hospital of Nanjing Military Command, dividing into four groups: POP with or without coexisting occult stress urinary incontinence (OSUI) in preoperation, women with persistent stress urinary incontinence (SUI) in postoperation, women without SUI in postoperation. The pudendal nerve function in preoperation was measured by using Solar Urodynamic Neuro Module, including pudendal nerve terminal motor latency (PNTML), and amplitude. RESULTS: There were statistical significance on bilateral PNTML between POP coexisting OSUI group and only severe POP group [(2.62±0.23) versus (2.40±0.26) ms in right of PNTML, (2.55± 0.21) versus (2.37 ±0.30) ms in left of PNTML; all P<0.05], but no statistical significance on bilateral amplitude (P>0.05). Compared de novo SUI group with POP group in postoperation, de novo SUI group's right of PNTML was significantly increased [(2.74±0.16) versus (2.47±0.26) ms; P< 0.05]; and the right of PNTML was extending 2.5 standard deviation at least compared with the health's [(2.10±0.20) ms]. CONCLUSIONS: The PNTML of pudendal nerve of POP coexisting OSUI is severe than only severe POP, the velocity of nerve conduction is slowing, and PNTML extension has a predictive value for postoperative urinary incontinence. When the right of PNTML of preoperative POP increased by at least 2.5 standard deviations than health's, the risk of SUI postoperative strongly increased, and a anti-incontinence surgery at the same time following pelvic prolapse surgery should be adviced.

Pelvic organ prolapse in a cohort of women treated for stress urinary incontinence.

OBJECTIVE: The aim of our study was to observe pelvic organ prolapse (POP) over time, treated and untreated, in a group of highly characterized women being followed up subjectively and objectively over 5-7 years following continence surgery. STUDY DESIGN: We measured baseline prolapse symptoms and anatomic prolapse in subjects enrolled in the trial of midurethral sling (TOMUS) and E-TOMUS, and measured these same parameters annually for 5-7 years after the index surgery. Additional information about subsequent treatment for POP was also recorded. RESULTS: In all, 597 women were randomized to 1 of 2 midurethral sling procedures in the TOMUS; concomitant vaginal procedures for POP were allowed at the surgeon's discretion. Stage 2 POP was present at baseline in 291 subjects (49%). Symptoms of POP were reported in 67 (25%). Of the asymptomatic women, 34 of 223 (15%) underwent a concomitant POP repair at the time of index sling surgery. Anatomic progression of prolapse in women with asymptomatic, unoperated stage 2 POP over the next 72 months was infrequent and occurred in only 3 of 189 subjects (2%); none underwent surgery for POP. Most symptomatic women (47/67 [70%]) underwent a concomitant repair for POP at the index sling surgery. Three of the 47 women who had undergone concomitant repair for symptomatic stage 2 POP underwent repeat POP surgery (2 at 36 months and 1 at 48 months.) CONCLUSION: For patient populations similar to the TOMUS and E-TOMUS populations, surgeons may counsel women with asymptomatic stage 2 POP that their prolapse is unlikely to require surgery in the next 5-7 years.
