Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

BACKGROUNDSome patients with pelvic organ prolapse may suffer from lower urinary tract symptoms (LUTS), especially stress urinary incontinence (SUI) named de novo SUI after pelvic floor reconstruction. This study aimed to investigate the incidence and risk factors of de novo SUI.

METHODSThis is a nested case-control study of 533 patients who underwent pelvic floor reconstruction due to pelvic organ prolapse (POP) at the Department of Gynecology in Peking University People's Hospital from January 2011 to March 2013. According to the inclusion and exclusion criteria, 401 patients were enrolled in the study with the follow-up rate of 74.8% (101 patients lost to follow-up). There were 75 patients with de novo SUI postoperatively. According to the ratio of 1:3, we ensured the number of control group (n = 225). The preoperative urinary dynamics, POP-quantification scores, and LUTS were compared between the two groups by univariate and multivariate logistic regression analyses to investigate the risk factors of de novo SUI.

RESULTSThe incidence of de novo SUI was 25% (75/300). Univariate analysis showed that the ratio of lower urinary tract obstruction (LUTO) before surgery in de novo SUI group was significantly higher than the control group (odds ratio [OR] = 2.1, 95% confidence interval [CI] [1.1-4.0], P = 0.022). The interaction test of LUTO and other factors displayed that Aa value was an interaction factor. With the increasing score of Aa, the incidence of de novo SUI become higher (OR = 2.1, 95% CI [1.0-3.7], P = 0.045). After multivariable adjustment, multiple regression analysis showed that LUTO was independently associated with a greater risk of de novo SUI after pelvic floor surgery (OR = 2.3, 95% CI [1.2-4.6], P = 0.013).

CONCLUSIONSPreoperative LUTO in patients with POP is a high-risk factor of de novo SUI, and high score of Aa-point is related to the occurrence of de novo SUI, which might be due to the outlet obstruction caused by bladder prolapse.

This study investigated the prevalence and risk factors of urinary incontinence (UI) among perimenopausal women in Wuhan. A cross-sectional survey was performed on 1067 women aged 40-65 years sampled in Wuhan urban area from April to October 2014. Information about demographic characteristics, menstruation, parity and UI symptoms was collected using a questionnaire. The data were evaluated by Chi-square test and multiple Logistic regression analysis. The prevalence rate of UI was 37.2%, with stress UI (32.2%) being more prevalent than urgency UI (21.6%) and mixed UI (16.6%). 31.2% women with UI stated that UI had negative impact on their life. Risk factors for UI included menstrual disorder, menopause, overweight, perineal laceration, atrophic vaginitis, constipation and pelvic organ prolapse. Appropriate investigation apropos the factors associated with UI should be performed to diminish its impact on women's life.

Pelvic organ prolapse (POP) is non-fatal conditions which can markedly affect a patient's quality of life. Multiple recently developed pelvic reconstructive surgeries have led to a recent expansion in China. In this study, we would like to discuss various aspects of the evaluation and management of POP and raise the question of what is sufficient evidence for the adoption of innovative treatments for POP.

INTRODUCTIONThis retrospective study assessed the surgical outcomes of patients for whom the transobturator polypropylene mesh kit was used for the management of pelvic organ prolapse (Gynecare Prolift) in a tertiary urogynaecological centre in Singapore from January 1, 2006 to December 31, 2007.

METHODS169 patients (2006 n = 95; 2007 n = 74) with total (n = 76), anterior (n = 82) and posterior (n = 11) Prolifts were followed up for two years post-surgery.

RESULTSIntraoperatively, the incidence of haematoma, blood loss > 1,000 mL and blood transfusion was lower in 2007 than in 2006, although the difference was not statistically significant. One (1.4%) patient had rectal perforation in 2007. The mesh erosion rates were similar for all Prolift types (total 17.2%; posterior 14.5%; anterior 18.2%). Two patients, who had total Prolift in 2006, required mesh excision under anaesthesia for mesh extrusion. 138 (81.7%) patients were available for review at two years - nine (6.5%) patients had recurrent cystourethrocoeles and two (1.4%) had recurrent vault prolapse. Of the nine patients who had total Prolift with uterine conservation, two (1.4%) had recurrent uterine descent. The subjective cure rates two years after Prolift surgery were 98.7% for patients from 2006 and 100% for patients from 2007. The objective cure rates were 89.6% for patients from 2006 and 91.8% for patients from 2007.

CONCLUSIONProlift mesh surgery appears to have a very high success rate for pelvic reconstructive surgery. The learning curve of the surgeon may, however, be a factor determining surgical outcome in these patients.
