Introduction and hypothesis
This committee opinion paper summarizes available evidence about recurrent pelvic organ prolapse (POP) to provide guidance on management.Method
A working subcommittee from the International Urogynecological Association (IUGA) Research and Development Committee was formed. The literature regarding recurrent POP was reviewed and summarized by individual members of the subcommittee. Recommendations were graded according to the 2009 Oxford Levels of Evidence. The summary was reviewed by the Committee.Results
There is no agreed definition for recurrent POP and evidence in relation to its evaluation and management is limited.Conclusion
The assessment of recurrent POP should entail looking for possible reason(s) for failure, including persistent and/or new risk factors, detection of all pelvic floor defects and checking for complications of previous surgery. The management requires individual evaluation of the risks and benefits of different options and appropriate patient counseling. There is an urgent need for an agreed definition and further research into all aspects of recurrent POP.2.

Introduction and hypothesis
The aim of this study was to compare the incidence of subsequent pelvic organ prolapse (POP) repair in women following radical hysterectomy versus total abdominal hysterectomy.Methods
From the Danish National Patient Registry, we collected data on all radical hysterectomies, all total abdominal hysterectomies, and all POP operations performed in Denmark from 1 January 1977 to 31 December 2009. We excluded patients with prior POP repair, POP diagnosis, or concomitant POP repair at hysterectomy. We analyzed the incidence of POP surgery using Kaplan–Meier curves and hazard ratio (HR).Results
In all, 5279 women underwent radical hysterectomy, and 63 of these underwent subsequent POP surgery. In the same period, 149,920 women underwent total abdominal hysterectomy, and 6107 of these had POP surgery subsequent to the hysterectomy. The cumulative incidence of POP surgery was significantly lower for radical hysterectomy than for abdominal hysterectomy—3.4 % and 9.5 %, respectively, at the end of the study period, yielding a crude HR of 0.36 and an adjusted HR of 0.40 in favor of the radical hysterectomy. The distribution of POP operations in the defined compartments was the same for the two types of hysterectomy.Conclusions
This study found a significantly lower incidence of subsequent POP operations among women who undergo radical hysterectomy than total abdominal hysterectomy.3.

Introduction and hypothesis
The aim of this study was to investigate the association between patient age at the time of hysterectomy and subsequent pelvic organ prolapse (POP) surgery.Methods
We gathered data on all benign hysterectomies and POP surgeries performed in Denmark on Danish women from 1977 to 2009 from the Danish National Patient Registry. The cohort consisted of 154,882 hysterectomized women, who were followed up for up to 32 years. Survival analysis for each age group at hysterectomy was performed using Kaplan–Meier product limit methods.Results
For all hysterectomized women, we found that low age at hysterectomy yielded a lower risk of subsequent POP surgery than did hysterectomy at an older age. This difference diminished after stratification by indication; all non-POP hysterectomies had a low cumulative incidence at 8–11 % at the end of the follow-up period. For all women hysterectomized, the predominant compartment for POP surgery was the posterior. Women hysterectomized when aged over 66 years had a higher proportion of POP surgery in the apical compartment than in the other age groups (p?=?0.000).Conclusion
Our findings indicate that age at hysterectomy only marginally influences the risk of subsequent POP surgery for women hysterectomized for indications other than POP. If POP is the indication for hysterectomy, the risk of undergoing subsequent POP surgery increases substantially.4.

Introduction and hypothesis
Pelvic organ prolapse (POP) is defined as the coexistence of anatomical POP and relevant symptoms. Vaginal bulge is the symptom most closely associated with the anatomical condition in nonpregnant women. Even if childbearing is a major risk factor for the development of POP, there is scant knowledge on the prevalence of specific POP symptoms, and how these symptoms relate to anatomical POP during pregnancy and postpartum. The aim of this study was to explore whether vaginal bulge symptoms were associated with anatomical POP in pregnancy and postpartum, and to present the prevalence of vaginal bulge symptoms throughout this period.Methods
A prospective observational study was carried out following 300 nulliparous pregnant women with repeat assessments from mid-pregnancy until 1 year postpartum. Symptoms of vaginal bulge defined as the sensation of a vaginal bulge inside and/or outside the vagina were assessed by electronic questionnaires. Anatomical POP defined as pelvic organ prolapse quantification system (POP-Q) stage ≥2 has been presented in a previous publication and showed a range of 1–9%. The association between the symptom vaginal bulge and anatomical POP at the various visits was analyzed using Fisher’s exact test.Results
Prevalence of vaginal bulge ranged between 16 and 23%. At 6 weeks postpartum the symptom was associated with anatomical POP; otherwise, these two features were unrelated.Conclusions
The symptom vaginal bulge was barely associated with anatomical POP, and cannot identify anatomical POP in pregnancy or postpartum.5.

Background
Prolonged ileus is a common complication following gastrointestinal surgery, with an incidence of up to 40 %. Investigations examining pharmacological treatment of ileus have proved largely disappointing; however, recently, several compounds have been shown to have benefited when used as prophylaxis to prevent ileus.Objective
This review aimed to evaluate the safety and efficacy of compounds which have been recently developed or repurposed to reduce bowel recovery time, thereby preventing ileus.Data sources
Data were taken from a systematic review of the MEDLINE, EMBASE and Cochrane Library Databases, in addition to manual searching of reference lists up to April 2015. No limits were applied.Study selection
Only randomized trials were eligible for inclusion.Interventions
Opioid receptor antagonists, ghrelin receptor agonists and serotonin receptor agonists used for the prevention of postoperative ileus in gastrointestinal surgery.Main outcome measures
Outcomes of time to first defecation, first flatus and composite bowel recovery endpoints (GI2 and GI3) were used to determine efficacy. Pooled treatment effects were presented as the standard mean difference or as hazard ratios alongside the corresponding 95 % confidence intervals. Risk of bias was assessed using the Cochrane risk of bias framework.Results
A total of 17 studies were included in the final analysis. The μ-opioid receptor antagonist alvimopan and serotonin receptor agonists appeared to significantly shorten the duration of ileus. The use of Ghrelin receptor agonists did not appear to have any effect in five trials. No publication bias was detected.Limitations
Most of the trials were poorly reported and of mixed quality. Future studies must focus on the development of a set of core outcomes.Conclusions
There is evidence to make a strong recommendation for the use of alvimopan in major gastrointestinal surgery to reduce postoperative ileus. Further randomized trials are required to establish whether serotonin receptor agonists are of use. Identifying a low-cost compound to promote bowel recovery following surgery could reduce complications and shorten duration of hospital admissions.7.

Summary
In this study, we attempt to determine the clinical characteristic and risk factors of postoperative pneumonia (POP) after hip fracture surgery in a well-defined hip fracture cohort. We find that intrinsic factors as well as major clinical interventions were all important risk factors of POP.Introduction
Postoperative pneumonia (POP) is one of the major complications following hip fractures surgery. However, the risk factors of POP are not well studied in hip fracture cohorts. We attempt to determine the clinical characteristic and risk factors of POP after hip fracture surgery in a well-defined hip fracture cohort.Methods
Datasets from a prospective hip fracture cohort study with a 2-year follow-up period, from 2000 to 2011, were reanalyzed for characteristics of POP. Multivariate Cox proportional regression was used to evaluate the association between the incidence of POP and all-cause mortality. Multivariate logistic regression was used to screen for potential risk factors of POP by analyzing demographic factors, comorbidities, major clinical interventions, and hematological parameters.Results
In 1429 patients who underwent hip surgery, the incidence of POP was 4.9 % (n?=?70). All-cause mortality of patients with POP was significantly higher than that of patients without POP at 30 days (hazard ratio (HR) 3.05, 95 % confidence intervals (CI) 1.88–4.94), 1 year (HR 1.87, 95 % CI 1.41–2.48), and 2 years (HR 1.57, 95 % CI 1.23–1.99) postoperatively. Multivariate logistic regression showed that intrinsic factors (advanced age, anemia, diabetes, prior stroke, number of comorbidities, ASA score ≥III, and some laboratory biomarkers) as well as major clinical interventions were all significant risk factors for POP.Conclusion
Intrinsic factors and major clinical interventions were all important risk factors of POP in patients after hip fracture surgery. Targeted preventive measures to mitigate the above risk factors may help in reducing the incidence of POP.8.

Introduction and hypothesis
Polypropylene is a material that is commonly used to treat pelvic floor conditions such as pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Owing to the nature of complications experienced by some patients implanted with either incontinence or prolapse meshes, the biocompatibility of polypropylene has recently been questioned. This literature review considers the in vivo response to polypropylene following implantation in animal models. The specific areas explored in this review are material selection, impact of anatomical location, and the structure, weight and size of polypropylene mesh types.Methods
All relevant abstracts from original articles investigating the host response of mesh in vivo were reviewed. Papers were obtained and categorised into various mesh material types: polypropylene, polypropylene composites, and other synthetic and biologically derived mesh.Results
Polypropylene mesh fared well in comparison with other material types in terms of host response. It was found that a lightweight, large-pore mesh is the most appropriate structure.Conclusion
The evidence reviewed shows that polypropylene evokes a less inflammatory or similar host response when compared with other materials used in mesh devices.9.

Introduction and hypothesis
Hysterectomy is often performed at the time of pelvic organ prolapse (POP) surgery; yet, there is insufficient evidence regarding the specific effect of hysterectomy on outcomes. We sought to determine the outcomes and associated short-term complications of mesh-based POP surgery with and without concurrent hysterectomy.Methods
We utilized the New York Statewide Planning and Research Cooperation System (SPARCS) database to identify patients under 55 years of age undergoing surgeries for POP with mesh between 2009 and 2014. Patients who had a hysterectomy at the time of mesh-based POP surgery were compared with those who underwent mesh-based POP surgery without hysterectomy. Outcome measures of the patient groups before and after propensity score matching were compared. We assessed the difference Chi-squared tests and log-rank tests in the entire cohort and Mantel–Haenszel stratified Chi-squared tests and Prentice-Wilcoxon tests in the matched cohort.Results
A total of 1,601 women underwent mesh-based POP surgery. 921 patients underwent concurrent hysterectomy, whereas 680 had mesh-based uterine-preserving POP surgery. After propensity score matching, there was no difference in reintervention rates between groups for up to 3 years. Concurrent hysterectomy with mesh-based POP repair was consistently associated with longer hospitalization (20.0% vs 12.8% stayed longer than 2 days) and higher charges (median charges were $22,689 vs $19,273).Conclusions
Concurrent hysterectomy during mesh-based POP surgery in patients under 55 years led to more expensive charges and a longer stay compared with uterine-preserving mesh surgery. There was no difference in reintervention rates between groups for up to 3 years.10.
Introduction and hypothesis
Hysterectomy and pelvic organ prolapse (POP) surgeries are two of the most common gynecologic surgeries conducted for benign conditions. This nationwide retrospective cohort study explored the risk of subsequent POP surgery following hysterectomy without simultaneous POP surgery.Methods
This study identified 7298 patients who underwent hysterectomy between January 1, 2000, and December 31, 2012, from the Taiwan National Health Insurance (NHI) Research Database. A comparison cohort was constructed comprising 29,192 age-matched patients who had not undergone hysterectomy. All hysterectomy and control patients were followed until they required POP surgery, withdrew from the NHI system, died, or December 31, 2012. Patients were excluded if they underwent POP surgery before or at the time of hysterectomy.Results
The adjusted hazard ratio (aHR) of subsequent POP surgery in subjects with hysterectomy was higher [2.60, 95% confidence interval (CI) 1.79–3.78] than that of controls during the follow-up period. Compared with patients who had not undergone hysterectomy, the highest risks of subsequent POP surgery was noted in those who had undergone vaginal hysterectomy (VH; HR 6.29, 95% CI 1.54–25.79) followed by those who underwent laparoscopy-assisted VH (LAVH; HR 3.77, 95% CI 2.43–5.85).Conclusions
Hysterectomy may increase the risk of subsequent POP surgery, and various hysterectomy techniques, particularly VH and LAVH, may increase the risk of subsequent POP surgery.11.

Introduction and hypothesis
Pelvic organ prolapse (POP) recurrence after surgery is a major problem. POP that is more advanced preoperatively is associated with a higher risk of recurrence postoperatively. We hypothesized that women with a stage 2 cystocele differ from those with a stage 3 or 4 cystocele. The aim of this study was to compare the baseline characteristics of women with mild and those with more advanced cystocele.Methods
Patients had participated in one of two multicenter prospective cohort studies on women undergoing conventional anterior colporrhaphy without previous POP surgery. This was a secondary analysis of these data. Women with a preoperative cystocele stage 2 were compared with women with a stage 3 or 4 cystocele. Logistic regression models were employed to calculate odds ratios (OR) and 95% confidence intervals (CI).Results
Two hundred and sixty-nine women were assessed, of whom 132 (49.1%) had an advanced cystocele. Only older age was significantly associated with advanced cystocele preoperatively, with an OR of 1.07 (95% CI 1.04–1.10). There were no significant differences between women with advanced or stage 2 cystocele in body mass index, vaginal deliveries, assisted delivery, positive family history of POP, concurrent rectocele, concurrent uterine of vaginal vault prolapse, major levator ani muscle defects, or levator hiatal area.Conclusions
Women with advanced cystocele were significantly older than women with stage 2 cystocele. This raises the question whether it would be favorable to perform POP surgery in an earlier stage, i.e., at a younger age, in order to prevent POP recurrence.12.

Introduction and hypothesis
In order to assess the outcome following surgery for urinary incontinence (UI) and pelvic organ prolapse (POP) the importance of patient-reported outcome measures, in addition to the clinical objective measures, has been recognised. The International Consultation on Incontinence has initiated the development and evaluation of disease-specific questionnaires (ICIQ) to compare the patient’s degree of improvement. Alternatively, the Patient’s Global Impression of Improvement (PGI-I score) with an inherent before–after assessment has been widely accepted in recent studies. The aim of this study was to compare the PGI-I versus the ICIQ score for women undergoing UI or POP surgery.Methods
This study is based on self-administered pre- and postoperative questionnaires, completed by women undergoing surgery for UI or POP in Denmark in 2013. Weighted Kappa statistics and 95 % limits of agreement method were used when comparing the PGI-I and ICIQ scores.Results
Among the 3,310 women included the PGI-I score showed a higher improvement than the IQIC score, for UI 0.83 (CI 95 %: 0.80–0.85) vs 0.62 (0.60–0.64) and for POP 0.77 (0.75–0.78) vs 0.66 (0.65–0.67).Conclusions
The PGI-I score renders higher satisfaction than the ICIQ score and the PGI-I score overestimates the improvement following UI and POP surgery.13.

Objective
Attrition, or loss to follow-up, is a common problem in studies of type 2 diabetes remission following roux-en-Y gastric bypass (RYGB) and is often correlated with weight loss. Thus, reported rates of remission may be inflated by attrition bias. We investigate the effect of attrition bias on reported diabetes remission rates following RYGB.Methods
Using sensitivity analyses, we identified sets of attrition and remission rates that produced simulated outcomes within 95% confidence intervals of the reported outcomes from five studies of diabetes remission following RYGB.Results
Potential attrition bias varied greatly, yielding possible remission rates of diabetes ranging from 20 to 40% at 1 year. For studies with the attrition greater than ~ 20%, estimates that ignored attrition overestimated diabetes remission rates. Kaplan-Meier estimates were less affected by attrition. Potential for bias was most evident in the study with the largest sample size.Conclusion
Researchers, clinicians, and policymakers can measure potential attrition bias in clinical studies. In the case of remission of diabetes following RYGB, the potential bias in reported remission rates is generally less than 10%, varies considerably among studies, and is primarily driven by attrition rate and study size. Studies with very large sample sizes may provide a narrow confidence interval around a biased estimate.15.

Introduction and hypothesis
Women have a lifetime risk of undergoing pelvic organ prolapse (POP) surgery of 11–19%. Traditional native tissue repairs are associated with reoperation rates of approximately 11% after 20 years. Surgery with mesh augmentation was introduced to improve anatomic outcomes. However, the use of synthetic meshes in urogynaecological procedures has been scrutinised by the US Food and Drug Administration (FDA) and by the European Commission (SCENIHR). We aimed to review trends in pelvic organ prolapse (POP) surgery in England.Methods
Data were collected from the national hospital episode statistics database. Procedure and interventions-4 character tables were used to quantify POP operations. Annual reports from 2005 to 2016 were considered.Results
The total number of POP procedures increased from 2005, reaching a peak in 2014 (N?=?29,228). With regard to vaginal prolapse, native tissue repairs represented more than 90% of the procedures, whereas surgical meshes were considered in a few selected cases. The number of sacrospinous ligament fixations (SSLFs) grew more than 3 times over the years, whereas sacrocolpopexy remained stable. To treat vault prolapse, transvaginal surgical meshes have been progressively abandoned. We also noted a steady increase in uterine-sparing, and obliterative procedures.Conclusions
Following FDA and SCENIHR warnings, a positive trend for meshes has only been seen in uterine-sparing surgery. Native tissue repairs constitute the vast majority of POP operations. SSLFs have been increasingly performed to achieve apical support. Urogynaecologists’ training should take into account shifts in surgical practice.16.

Introduction and hypothesis
Uterine-sparing procedures could be attractive in patients concerned about fertility preservation and corporeal image changes. Transvaginal uterosacral ligaments (USLs) hysteropexy can provide a mesh-free technique for uterine suspension. This video is intended to serve as a tutorial for surgical steps.Methods
A 38-year-old woman with symptomatic stage III POP desired preserving fertility. After proper counseling, the patient was admitted for vaginal hysteropexy through bilateral high USL suspension according to the featured technique.Results
Prolapse repair was successfully achieved without complications. We had already published a series of 20 cases that confirmed that transvaginal USLs hysteropexy is a promising technique for correcting genital prolapse with uterus preservation.Conclusion
Transvaginal USLs hysteropexy provides a feasible technique for apical support without the use of prosthetic material. This procedure could be attractive to women who desire a uterine-sparing surgical option.17.

Introduction and hypothesis
Synthetic meshes have proven to increase efficacy of pelvic organ prolapse (POP) repair, but associated complications are not rare. Bladder mesh extrusion is one of the most serious adverse events following POP surgery with mesh. The aim of this video was to describe endoscopic and vaginal approaches for treating a bladder-mesh extrusion.Methods
A 52-year-old female patient with a history of vaginal POP surgery with mesh was referred for severe pelvic and perineal pain, dyspareunia, and dysuria. She was found to have a bladder calculus on a mesh extrusion. The calculus was removed by endoscopic lithotripsy before vaginal mesh excision was performed.Conclusions
With the use of synthetic vaginal mesh, the incidence of bladder-mesh extrusion could increase. This didactic video will be helpful to surgeons required to manage such cases using a minimally invasive treatment.18.

Introduction and objective
Little is known about the extent to which women in low- and middle-income countries suffer with urological and urogynaecological complications of childbirth. This study measured the prevalence of obstetric fistula and symptomatic pelvic organ prolapse (POP) in east and north Ethiopia.Methods
We randomly selected 23,023 women of reproductive age (15–49 years) from 113 villages in East Harraghe, South Gondar and West Gojjam, Ethiopia. Trained local health workers administered a validated face-to-face survey and a team of researchers verified data by readministering a random selection (5 %) of the survey. All suspected fistulae were followed up to confirm a clinical diagnosis.Results
Mean age was 29.5 [standard deviation (SD) 8.05] years. Only 22 % of women were knowledgeable about the symptoms of fistula. The prevalence of all obstetric fistulae was 6:10,000 reproductive-aged women [95 % confidence interval (CI) 3–8], of untreated fistula 2:10,000 (95 % CI 0–4) and of symptomatic POP 100:10,000 (95 % CI 86–114).Conclusion
The prevalence of obstetric fistula in these rural zones of Ethiopia is relatively low and reflects a substantial reduction from previous reports. Significant numbers of women suffer with symptomatic POP, for which surgical and nonsurgical treatments would be beneficial.Brief summary
Obstetric fistula in north and east Ethiopia is relatively low; however, the many women with symptomatic pelvic organ prolapse could benefit from treatment.19.

Introduction and hypothesis
There is a need for expanded access to safe surgical care in low- and middle-income countries (LMICs) as illustrated by the report of the 2015 Lancet Commission on Global Surgery. Packages of closely-related surgical procedures may create platforms of capacity that maximize impact in LMIC. Pelvic organ prolapse (POP) and genital fistula care provide an example. Although POP affects many more women in LMICs than fistula, donor support for fistula treatment in LMICs has been underway for decades, whereas treatment for POP is usually limited to hysterectomy-based surgical treatment, occurring with little to no donor support. This capacity-building discrepancy has resulted in POP care that is often non-adherent to international standards and in non-integration of POP and fistula services, despite clear areas of similarity and overlap. The objective of this study was to assess the feasibility and potential value of integrating POP services at fistula centers.Methods
Fistula repair sites supported by the Fistula Care Plus project were surveyed on current demand for and capacity to provide POP, in addition to perceptions about integrating POP and fistula repair services.Results
Respondents from 26 hospitals in sub-Saharan Africa and South Asia completed the survey. Most fistula centers (92%) reported demand for POP services, but many cannot meet this demand. Responses indicated a wide variation in assessment and grading practices for POP; approaches to lower urinary tract symptom evaluation; and surgical skills with regard to compartment-based POP, and urinary and rectal incontinence. Fistula surgeons identified integration synergies but also potential conflicts.Conclusions
Integration of genital fistula and POP services may enhance the quality of POP care while increasing the sustainability of fistula care.20.
