Introduction and Hypothesis: Levator ani muscle (LAM) avulsion is associated with pelvic organ prolapse (POP). There is limited information on the prevalence of LAM avulsion in Chinese women with POP. This study evaluated the prevalence of LAM avulsion in women presenting with POP and the effects on their quality of life (QoL)., Methods: This prospective study was conducted in a tertiary urogynecology center. Chinese women presenting with POP were recruited and completed standardized questionnaires exploring their symptoms and QoL and underwent gynecological examination to assess the stage of POP and involved compartments. Four-dimensional translabial ultrasound (US) was performed on all women, and evaluation of LAM avulsion was done offline., Results: Three hundred and ninety-eight women completed the study. The prevalence of LAM avulsion was 38.9% [95% confidence interval (CI) 34.1-43.7%]; 31 (7.8%), 26 (6.5%), and 98 (24.6%) had left, right, and bilateral LAM avulsion, respectively. LAM avulsion was associated with a more advanced stage of prolapse (P < 0.005) and prolapse of stage ≥II of all three compartments. Bilateral LAM avulsion was associated with a more severe stage of prolapse. More women with LAM avulsion reported bothersome symptoms of prolapse and had higher Pelvic Organ Prolapse Distress Inventory (POPDI) and Urinary Incontinence Questionnaire (UIQ) scores, implying more impairment in QoL. However, after multivariate linear regression analysis, POP stage remained a significant predictor of POPDI and UDI scores (P ≤ 0.006); LAM avulsion was not a predictor (P = 0.2 and 0.27, respectively)., Conclusions: LAM avulsion was detected in 39% of Chinese women with POP. It was associated with a more advanced POP stage, and these women had more impairment of QoL. However, LAM avulsion was not an independent factor influencing the QoL of these women.

Objectives: To compare the 5-year subjective and objective outcomes of transobturator tension-free vaginal tape alone versus the same procedure with concomitant pelvic floor repair surgery for pelvic organ prolapse in women with urinary stress incontinence., Design: Prospective cohort study., Setting: Urogynaecology unit at a university hospital in Hong Kong., Patients: Of 218 women, 96 (44%) received transobturator tension-free vaginal tape alone and 122 (56%) received transobturator tension-free vaginal tape with concomitant pelvic floor repair surgery from September 2004 to December 2009. The women were followed up annually for up to 5 years after the operation., Main Outcome Measures: The 5-year subjective and objective cure rates were assessed. Subjective cure was defined as no urine loss during physical activity and objective cure was defined as no urine leakage on coughing during urodynamic study., Results: Overall, 88 women receiving transobturator tension-free vaginal tape alone and 101 women receiving transobturator tension-free vaginal tape with concomitant pelvic floor repair surgery were followed up for 5 years after operation. The subjective and objective cure rates of the two groups were 70.5% versus 94.1% (P<0.01) and 80.3% versus 85.7% (P=0.58), respectively., Conclusions: Transobturator tension-free vaginal tape is an effective treatment for urinary stress incontinence in women who received it alone or with concomitant pelvic floor repair surgery for pelvic organ prolapse, providing high subjective and objective efficacy for up to 5 years after operation. Transobturator tension-free vaginal tape with concomitant pelvic floor repair surgery achieved similar, if not better, long-term outcome compared with transobturator tension-free vaginal tape alone.

Introduction and Hypothesis: To evaluate the effect of levator ani muscle (LAM) injury on pelvic floor disorders and health-related quality of life in Chinese primiparous women during the first year after delivery., Methods: At 8 weeks and 12 months after delivery, 328 women were assessed for symptoms of pelvic floor disorders and quality of life using the standardised questionnaire, POP-Q; and translabial ultrasound to detect LAM injury. Descriptive analysis, independent sample t test, non-parametric testing, Chi-squared test and two-sided Fisher's exact test were used., Results: At 8 weeks after delivery, 48 (19.0% [95% CI, 14.2-23.8%]) women with vaginal delivery had LAM injury; 38 women (79.2%) had persistent LAM injury at 12 months. At 8 weeks, LAM injury was associated with prolapse symptoms, descent at Pelvic Organ Prolapse Quantification (POP-Q) Aa and Ba points and a higher Pelvic Organ Prolapse Distress Inventory (POPDI) general and Urinary Distress Inventory (UDI) Obstructive subscale score. At 12 months, it was not associated with prolapse symptoms, Pelvic Floor Distress Inventory (PFDI) or Pelvic Floor Impact Questionnaire (PFIQ). There was also no association between stress urinary incontinence (SUI), urge urinary incontinence (UUI), mixed urinary incontinence (UI), faecal incontinence (FI) with LAM injury at both time points., Conclusions: Seventy-nine per cent of women who had LAM injury at 8 weeks after vaginal delivery had persistent LAM injury at 12 months. LAM injury was associated with prolapse symptoms, lower POP-Q Aa and Ba points at 8 weeks after delivery and a higher POPDI general and UDI Obstructive subscale scoring. However, we are not able to confirm the association between LAM injury and SUI, UUI, mixed UI, FI at 8 weeks or 12 months after delivery; or prolapse symptoms, PFDI or PFIQ scores at 12 months after delivery.

Background: Women suffering from urinary incontinence have impaired quality of life (QoL). Pelvic floor muscle training (PFMT) has been recommended to be the first-line treatment for them., Aims: This study evaluated the role of (PFMT) in women with urinary incontinence., Materials and Methods: All women suffering from urinary incontinence without pelvic organ prolapse who attended the urogynaecology unit of a university hospital from January 2009 to June 2010 were recruited. Urinary symptoms and impact on QoL were assessed using the Chinese validated Urogenital Distress Inventory short form (UDI-6) and Incontinence Impact Questionnaire short form (IIQ-7) before and after PFMT. Urodynamic studies (UDS) were used to differentiate the diagnoses of urinary incontinence., Results: Three hundred and seventy-two women, aged 52.3 ± 10.8 years and practised PFMT for 9.9 ± 7.3 months, completed the study. Over 65% recorded improvement in both UDI-6 and IIQ-7. Stratified for urodynamic diagnosis, stress incontinence group and those who had no UDS abnormality had significant improvement in their urinary symptoms and QoL after PFMT. UDI-6 and IIQ-7 also improved significantly after PFMT in groups where the clinical presentation was stress incontinence, overactive bladder symptoms or mixed urinary incontinence. Age was not associated with a significant difference in the response to PFMT., Conclusions: Pelvic floor muscle training appears to be an effective first-line intervention for improving urinary symptoms and QoL of women presenting with urinary incontinence. Future studies on long-term effectiveness and cost-effectiveness are also required., (© 2013 The Authors ANZJOG © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Objectives: To evaluate pelvic floor biometry of women 3-5 years after their first delivery. The effect of a subsequent delivery and the mode of delivery on pelvic floor biometry were also studied.Methods: Three-hundred and twenty-eight women who had been examined by translabial ultrasound during their first singleton pregnancy and at 8 weeks and 1 year postpartum, were invited for a follow-up 3-5 years later. The positions of the bladder neck, cervix, anorectal junction and hiatal area (HA) were evaluated using translabial ultrasound. The effects of parity, mode of delivery and levator ani muscle avulsion were studied.Results: A total of 240 women completed the study. Of these, 179 had one or more vaginal deliveries (VD) (VD-only group), 52 had one or more Cesarean sections (CS) (CS-only group) and nine had both VD and CS at follow-up. The mean interval between the first delivery and follow-up was 3.8 years. A significantly lower bladder neck and anorectal junction on Valsalva, a lower cervix at rest, on Valsalva and pelvic floor muscle contraction, and a greater HA were observed in the VD-only group at follow-up, compared with findings at 1 year of follow-up or in the first pregnancy. The findings were similar in the CS-only group, except without a lower anorectal junction on Valsalva. Compared with the primiparous VD-only group, a greater HA at rest was observed in the multiparous VD-only group (P = 0.027). The VD-only group had a greater HA than the CS-only group.Conclusions: At 3-5 years after first delivery, a lower bladder neck, cervix and anorectal junction, and a greater HA were observed compared with findings in the first trimester and at 1 year of follow-up, regardless of parity or mode of delivery. Women with two or more VDs had a greater HA compared with those who had only one VD, and women with at least one VD had a greater HA compared with those who delivered by CS only.

Introduction and hypothesis: This study aimed to determine the prevalence of urinary incontinence (UI), fecal incontinence (FI), and pelvic organ prolapse (POP) 3-5 years after the first pregnancy and their associated risk factors. Methods: We assessed 506 women using the Pelvic Floor Distress Inventory (PFDI) and the Pelvic Floor Impact Questionnaire (PFIQ). Maternal characteristics and obstetric data were analyzed using descriptive analysis, independent sample t test, chi-squared test, and logistic regression. Results: The prevalence of UI, FI, and POP, respectively, at a mean of 43 months after first delivery was 40.8, 6.6, and 10.2% following vaginal delivery (VD) and 22.7, 4.5, and 4.5% following cesarean section (CS). Stress urinary incontinence (SUI) was reported by more women following VD than CS (38.7 vs 22.4%, P = 0.010). Compared with 8 weeks' postpartum, more women reported SUI at this later follow-up visit (40.1 vs 19.5%, P < 0.001), but fewer reported FI. More women who had an instrumental delivery reported symptoms of POP compared with those who had a normal VD. Higher body weight and weight gain from first trimester were risk factors of SUI [odds ratio (OR) 1.03] and urge urinary incontinence (UUI) (OR 1.18), respectively. Women who delivered vaginally had higher PFDI subscales scores. Conclusions: VD increased UI risk. Higher body weight and weight gain from first trimester were risk factors for SUI and UUI, respectively. More women reported symptoms of POP following an instrumental delivery than those who had a normal VD. [ABSTRACT FROM AUTHOR]

Introduction and hypothesis: This study evaluated the responsiveness and minimal important differences (MID) of the Chinese Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ) in women undergoing urodynamic stress incontinence (USI) and/or pelvic organ prolapse (POP) treatment. Methods: One hundred and fifty-six women were assessed using the PFDI and PFIQ before and after they received continence surgery and or pelvic floor repair (PFR) surgery, or vaginal pessary. Symptom severity was recorded using a visual analog scale (VAS) before and after treatment as was rating of their satisfaction with the treatment they received. Responsiveness of the PFDI and PFIQ were evaluated by effect sizes, standardized response mean, paired samples t test or Wilcoxon Signed Rank Test. MID in the PFDI and PFIQ for different treatments were determined by satisfaction rating, change in VAS scoring, and distribution-based methods. Results: There were significant improvements in the respective subscales of PFDI and PFIQ, demonstrating moderate to great responsiveness after different treatments. The estimation of MID for the Urinary Distress Inventory (UDI) was −30 to −14 and the Urinary Impact Questionnaire (UIQ) was −28 to −14 for women who underwent continence surgery. The MID for the Pelvic Organ Prolapse Distress Inventory (POPDI) was −44 to −21, the Pelvic Organ Prolapse Impact Questionnaire (POPIQ) −40 to −27, the UDI −22 to −16, the UIQ −37 to −31, the Colo-Rectal-Anal Distress Inventory (CRADI) −37 to −14, and the Colo-Rectal-Anal Impact Questionnaire (CRAIQ) −34 to −6 for women who underwent PFR surgery; and estimation of MID for the POPDI was −16, the POPIQ −29, the UDI −28, the UIQ −17, the CRADI −25, and the CRAIQ −31 for women who received a vaginal pessary. The MID of the respective subscales were supported by the distribution-based methods. Conclusions: The Chinese PFDI and PFIQ instruments are responsive to change in women undergoing continence surgery, PFR surgery or vaginal pessary for USI or POP. [ABSTRACT FROM AUTHOR]

Introduction and hypothesis: The purpose of this study was to investigate the reliability and validity of the Chinese version of Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ). Methods: Women who presented for pelvic floor disorders completed the Chinese version of PFDI and PFIQ, SF-36, a 3-day urinary and fecal diary. POP-Q assessment, urodynamic study, anal manometry, and ultrasound were performed where appropriate. Results: Five hundred and ninety-seven women completed the study. The Cronbach's alpha and test-retest reliability of PFDI and PFIQ was 0.92 and 0.98, and 0.77 and 0.79, respectively. Convergent validity was demonstrated with negative correlation of PFDI and PFIQ with SF-36; positive correlation of staging of prolapse, urinary or fecal incontinent episodes with the respective subscales of PFDI and PFIQ. Conclusions: The Chinese version of PFDI and PFIQ are reliable and valid condition-specific health-related quality of life questionnaires for women with pelvic floor disorders.

Objective: To compare pelvic floor symptoms, quality of life, and complications in women with symptomatic pelvic organ prolapse (POP) with or without vaginal pessaries in addition to those who do pelvic floor exercises for 12 months.Methods: This was a parallel-group, single-blind, randomized controlled trial with 12 months of follow-up. Women with symptomatic stage I to stage III POP were randomized to either pelvic floor exercises training (control group) or pelvic floor exercises training and insertion of a vaginal pessary (pessary group). The primary outcome was the change of prolapse symptoms and quality of life by using the Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaires. Secondary outcomes included bothersome of prolapse symptoms, desired treatment, and any complications.Results: From December 2011 through November 2014, 311 women were screened and 276 were randomized as follows: 137 to the control and 139 to the pessary group. One hundred thirty-two (95.0%) women in the pessary group and 128 (93.4%) in the control group completed the study. The Pelvic Organ Prolapse Distress Inventory of Pelvic Floor Distress Inventory and the Pelvic Organ Prolapse Impact Questionnaire of Pelvic Floor Impact Questionnaire scores decreased in both groups after 12 months, but the mean score differences were higher in the pessary group (Pelvic Organ Prolapse Distress Inventory: -29.7 compared with -4.7, P<.01; Pelvic Organ Prolapse Impact Questionnaire: -29.0 compared with 3.5, P<.01). Complication rates were low and similar in both groups.Conclusion: We provided further evidence in nonsurgical treatment for POP. Prolapse symptoms and quality of life were improved in women using a vaginal pessary in addition to pelvic floor exercises.Clinical Trial Registration: Centre for Clinical Research and Biostatistics-Clinical Trials Registry, https://www2.ccrb.cuhk.edu.hk/web/?page_id=746, ChiCTR-TRC-11001796.
