Treatment Outcomes of Cesarean Scar Pregnancy Under a Novel Classification System: A Retrospective Cohort Study.

OBJECTIVES: To determine whether the new classification system published by Jordans et al for cesarean scar pregnancy (CSP) can guide management and treatment outcomes. METHODS: A retrospective study of women diagnosed with CSP from October 2010 to December 2022 in a single tertiary center was performed. Sonographic records of these women were classified into three types according to the classification published by Jordans et al. Treatment outcomes were compared across each type of CSP. RESULTS: The study included a total of 84 women, where 60 (71.4%), 17 (20.2%), and 7 (8.3%) of them were categorized into Type 1, 2, and 3 CSP, respectively. A total of 47 (55.9%) women were managed with methotrexate, 22 (26.2%) underwent surgical management of the CSP without removal of the Cesarean section (CS) niche, and 11 (13.1%) underwent surgery to remove the CSP and the CS niche. Overall treatment success rates for medical management and surgical management were 70 and 97%, respectively. Four women were managed expectantly and continued their pregnancies, among which three carried beyond 34 weeks and had good neonatal outcomes. CONCLUSIONS: The classification as published by Jordans et al is easily replicable and readily implemented clinically. Our findings show that a higher proportion of Type 1 and Type 2 CSP were treated successfully by a less invasive medical approach with a high success rate, whereas most Type 3 CSP required surgical resection to successfully remove the CSP and the CS niche. Prospective studies are required to confirm these findings and further validate the clinical utility of this nomenclature system.

Treatment outcome of women with urodynamic mixed urinary incontinence: an observational study.

INTRODUCTION AND HYPOTHESIS: Mixed urinary incontinence (MUI) is a common yet understudied condition. It remains a therapeutic challenge, with the presence of both stress urinary incontinence (SUI) and urgency urinary incontinence (UUI). There is limited information on the optimal management for women with urodynamic MUI (urodynamic stress incontinence and detrusor overactivity). We assessed the treatment outcome of pelvic floor muscle training (PFMT), medical treatment and surgery for women who were diagnosed with urodynamic MUI. METHODS: A prospective observational study was carried out on women with urodynamic MUI from 2010 to 2018. All women underwent clinical assessment and standardised urodynamic evaluation. All women received PFMT from a specialised continence advisor as initial management. Antimuscarinics and/or continence surgery were considered according to the woman's response and symptoms after PFMT. Subjective outcome after each treatment modality was analysed. RESULTS: A total of 198 women were included for analysis. All women received PFMT, 104 (52.5%) showing improvement in urinary incontinence. Eighty-seven (43.9%) women were offered antimuscarinics, of whom 58 (29.3%) showed subjective improvement in both SUI and UUI, and 10 (5%) reported a reduction in UUI but persistent SUI. A total of 55 (27.7%) women received surgical treatment, with 20 receiving continence procedures. Sixteen out of twenty (80%) of them reported improvement in both SUI and UUI. None reported worsening of urgency or UUI. Overall, across all treatment modalities, 73.8% of women showed improvement in both SUI and UUI. CONCLUSION: Future analyses can help to inform which patients will have a higher success rate after each treatment modality and help focus treatment effort on those with a high risk of persistent symptoms. This will provide relevant data in counselling women, giving reasonable expectations and directing the management of women with urodynamic MUI.

Effect of additional acupuncture to pelvic floor exercise on urinary incontinence: A randomized controlled trial.

AIMS: To investigate the additional benefit of acupuncture to pelvic floor exercise (PFE) on the improvement of urinary incontinence (UI) and quality of life (QoL) in women. METHODS: This was a single-blinded randomized controlled trial in a tertiary university hospital. Women with UI in various severity and types were randomized to receive either a weekly course of acupuncture with PFE or PFE alone for 6 weeks and then followed up for 24 weeks in every 6 weeks. Investigators were blinded to group allocation in pre- and postintervention assessments. Primary outcome was subjective changes of UI symptoms at 24 weeks. Secondary outcomes were episodes and severity of UI from bladder diary, severity by Visual Analogue Scale, and QoL scores by validated Chinese short-form of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). RESULTS: One hundred seventy-nine women were screened while 137 were randomized. Significant subjective improvement in UI symptoms was demonstrated at all follow-up, latest at 24 weeks (odds ratio [OR]: 2.29, 95% confidence Interval [CI]: 1.02-5.12, respectively), with reduced episodes and severity of UI after (p < 0.05), and a trend of improvement in IIQ-7 score (p = 0.05). No major adverse events occurred. History of 2 years or longer duration of UI symptoms was associated with lower effectiveness of acupuncture (OR: 0.08, 95% CI: 0.01-0.68).

International Urogynaecology Consultation chapter 1 committee 4: patients' perception of disease burden of pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: This manuscript from Chapter 1 of the International Urogynecology Consultation (IUC) on Pelvic Organ Prolapse (POP) reports on the patients' perception of disease burden associated with pelvic organ prolapse. MATERIALS AND METHODS: An international group containing a team of eight urogynaecologists, a physiotherapist and a statistician performed a search of the literature using pre-specified search terms in PubMed and Embase (January 2000 to August 2020). The division of sections within this report includes: (1) perception of POP and the relationship with body image and poor health; (2) a vaginal bulge as it impacts health and wellbeing in women; (3) the impact of POP on sexual life; (4) body image and pelvic floor disorders; (5) POP and mood; (6) appropriate use of treatment goals to better meet patients' expected benefits; (7) using health-related quality of life questionnaires to quantify patients' perception of POP; (8) The financial burden of POP to patients and society. Abstracts were reviewed and publications were eliminated if not relevant or did not include populations with POP or were not relevant to the subject areas as noted by the authors. The manuscripts were next reviewed for suitability using the Specialist Unit for Review Evidence (SURE) checklists for cohort, cross-sectional and case-control epidemiologic studies. RESULTS: The original individual literature searches yielded 2312 references of which 190 were used in the final manuscript. The following perceptions were identified: (1) women were found to have varying perceptions of POP including shame and embarrassment. Some regard POP as consequence of aging and consider there is no effective therapy. (2) POP is perceived as a vaginal bulge and affects lifestyle and emotional wellbeing. The main driver for treatment is absence of bulge sensation. (3) POP is known to affect frequency of sexual intercourse but has less impact on satisfaction. (4) Prolapse-specific body image and genital self-image are important components of a women's emotional, physical and sexual wellbeing. (5) POP is commonly associated with depression and anxiety symptoms which impact HRQoL although are not correlated with objective anatomical findings. (6) Patient-centered treatment goals are useful in facilitating communication, shared decision-making and expectations before and after reconstructive surgery. (7) Disease-specific HRQoL questionnaires are important tools to assess bother and outcome following surgery, and there are now several tools with Level 1 evidence and a Grade A recommendation. (8) The cost of POP to the individual and to society is considerable in terms of productivity. In general, conservative measures tend to be more cost-effective than surgical intervention. CONCLUSIONS: Patients' perception of POP varies in different patients and has a far-reaching impact on their overall state of health and wellbeing. However, recognizing that it is a combination of body image and overall health (which affects mental health) allows clinicians to better tailor expectations for treatment to individual patients. There are HRQoL tools that can be used to quantify these impacts in clinical care and research. The costs to the individual patient (which affects their perception of POP) is an area that is poorly understood and needs more research.

Prospective comparison of obstetric anal sphincter injury incidence between an Asian and Western hospital.

INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injury (OASIS) rates are reported to be higher in Asian women living in Western countries than in those living in Asia, but the reasons for the differences remain unclear. The objectives of this study were for a single examiner to prospectively compare OASIS rates in primiparous Asian women in an Asian and Western birth unit and determine potential birth factors that may influence the possible difference in OASIS incidence. METHODS: This was a prospective observational study based in Hong Kong, China, and Sydney, Australia, involving primiparous women > 36 weeks gestation of Asian descent undergoing vaginal delivery. A single examiner recorded basic patient demographics, observed all the deliveries at both sites, noting birthing techniques, and then examined the women, including a rectal examination, to determine OASIS incidence. RESULTS: Seventy births in Hong Kong and 66 in Sydney were studied. The incidence of OASIS was 34% in Sydney and 10% in Hong Kong (p = 0.001). Birthweight, epidural rate, body mass index, and instrumental delivery were higher in Sydney. Episiotomy rates were higher in Hong Kong (59.2% vs. 82.9%; p = 0.007). When comparing OASIS with no-OASIS, perineal length (OR = 0.36, 95% CI 0.17 to 0.76, p = 0.004) and birthweight (OR = 1.14, 95% CI 1.00 to 1.30, p = 0.039) were independent risk factors for OASIS. CONCLUSIONS: The incidence of OASIS in Asian women is significantly higher in a Western than in an Asian setting. In Asian women, perineal length and birthweight can affect the risk of OASIS at the time of vaginal delivery.

Prevalence of levator ani muscle avulsion and effect on quality of life in women with pelvic organ prolapse.

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.

An observational follow-up study on pelvic floor disorders to 3-5 years after delivery.

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.

Efficacy and outcomes of transobturator tension-free vaginal tape with or without concomitant pelvic floor repair surgery for urinary stress incontinence: five-year follow-up.

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.

A pilot study of urine cytokines in ketamine-associated lower urinary tract symptoms.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to investigate urine cytokine and chemokine levels in symptomatic ketamine abusers compared with age-matched controls. METHODS: Midstream urine specimens were collected in a prospective study of 23 ketamine abusers and 27 controls who had never used ketamine. Their basic demographic and urinary symptoms were compared. The urine was analyzed by a multiplex panel screen for 19 cytokines/chemokines: EGF, GM-CSF, GRO, IL-1Ra, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12p40, IL-12p70, IP-10, MCP-1, MIP-1b, sCD40L, sIL-2Ra, VEGF, MCP-4, and TARC using Luminex™ xMAP® technology. Protein concentration values were normalized to urine creatinine concentrations. RESULTS: Mean age of the control group was 21.1 ± 4.3 years (n = 27) and of the ketamine group was 20.6 ± 3.7 years (n = 23). All participants were women. The urine cytokine analysis showed a significant elevation in EGF levels in the ketamine group with lower urinary tract symptoms (LUTS) compared with the control group (p < 0.005). Levels of the remaining 18 proteins tested were not different from control values. CONCLUSIONS: Urinary EGF levels were increased among symptomatic ketamine abusers. This suggests inflammation and epithelial repair may play a role in ketamine-associated LUTS, and this may in turn help in understanding the pathophysiology of this disease entity, leading to better treatment options.

Effect of levator ani muscle injury on primiparous women during the first year after childbirth.

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.

Inside-out versus outside-in transobturator tension-free vaginal tape: a 5-year prospective comparative study.

OBJECTIVE: To compare the 1-year and 5-year outcomes of transobturator tension-free vaginal tape with outside-in and inside-out approaches in women with urinary stress incontinence, and to identify risk factors for treatment failure at 5 years. METHOD: A prospective observational study was carried out for women with urinary stress incontinence who underwent transobturator tension-free vaginal tape from September 2004 to March 2008 in a tertiary urogynecology center. Women (n = 213) had either an outside-in (n = 124) or inside-out (n = 89) procedure. They were followed up annually until 5 years after the operation. Subjective cure was defined as women not experiencing any urine loss on physical activity. Objective cure was defined as no urine leak at cough during a standard urodynamic study. RESULTS: At a mean follow up of 59.2 months, the subjective cure rates were 81.7% and 84.1%; the objective cure rate were 82.6% and 82.5% for the outside-in and inside-out approach, respectively. There was no statistically significant difference between the procedures. De novo overactive bladder syndrome (10.6% in outside-in and 14.6% in inside-out approach; P = 0.40) and de novo detrusor overactivity (5.8% in outside-in and 15% in inside-out approach; P = 0.11) was also comparable between the two groups. Complications at the fifth year were low and not significantly different among both methods. CONCLUSION: The outside-in approach and inside-out approach are both safe and effective in treating women with urinary stress incontinence up to 5 years.

Prevalence of urinary and fecal incontinence in Chinese women during and after their first pregnancy.

INTRODUCTION AND HYPOTHESIS: This study evaluated factors and their prevalence associated with urinary (UI) and fecal (FI) incontinence during and after a woman's first pregnancy. METHODS: Nulliparous Chinese women with no UI or FI before pregnancy were studied with a standardized questionnaire for UI and FI from early pregnancy until 12 months after childbirth. Maternal characteristics and obstetric data were analyzed using descriptive analysis, independent sample t test, chi-square test, and logistic regression. RESULTS: Three hundred and twenty-eight (74.2 %) women completed the study. The prevalence of antenatal UI increased with gestation. Overall, 192 (58.5 %), 60 (18.3 %), and 76 (23.1 %) had normal vaginal delivery, instrumental delivery, and cesarean section, respectively. Twelve months after delivery, prevalence of stress urinary incontinence (SUI) and urge urinary incontinence (UUI) was 25.9 % [95 % confidence interval (CI) 21.5-30.6] and 8.2 % (95 % CI 5.2-11.2), respectively. In those who delivered vaginally, the prevalence was 29.7 % and 9.1 %, respectively. Prevalence of FI was 4.0 % (95 % CI 1.9-6.1). On logistic regression, vaginal delivery [odds ratio (OR) 3.6], antenatal SUI (OR 2.8), and UUI (OR 2.4) were associated with SUI. Antenatal UUI (OR 6.4) and increasing maternal body mass index (BMI) at the first trimester (OR 1.2) were associated with UUI. Antenatal FI was associated with FI (OR 6.1). CONCLUSIONS: The prevalence of SUI, UUI, and FI were 25.9 %, 8.2 %, and 4.0 %, respectively, 12 months after delivery. Vaginal delivery, antenatal SUI, and UUI were associated with SUI; antenatal UUI and increasing maternal BMI at the first trimester were associated with UUI. Antenatal FI was associated with FI. Pregnancy, regardless of route of delivery and obstetric practice, had an effect on UI and FI.

Responsiveness of the Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire in women undergoing treatment for pelvic floor disorders.

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.

Measuring the angle of the subpubic arch using three-dimensional transperineal ultrasound scan: intraoperator repeatability and interoperator reproducibility.

OBJECTIVE: A method of measuring the subpubic arch angle using three-dimensional transperineal ultrasound scan (3DTUS) was developed, and the intraoperator repeatability and interoperator reproducibility were investigated. STUDY DESIGN: Using 3DTUS, volume data sets were obtained from the nine nulliparous pregnant women by three operators (A, B, and C) in each of the three study sessions. With volume reconstruction, a plane along the inferior edges of bilateral inferior pubic rami was obtained on the axial section. The angle made between the innermost points of both inferior pubic rami at the level of urethra and the inferoposterior point of symphysis pubis was measured as the subpubic arch angle. The intraoperator repeatability of the experienced operator (A) and the interoperator reproducibility between A, B, and C were assessed by the repeatability coefficient and the interoperator intraclass correlation (ICC), respectively. RESULTS: A total of 27 women were examined. The intraoperator repeatability was 4.73 degrees. The overall interoperator ICC was 0.860, and increased from 0.794 in the first session to 0.945 in the third session. CONCLUSION: With 3DTUS, it is feasible to measure subpubic arch angle with satisfactory intraoperator repeatability and interoperator reproducibility. This easy-to-learn technique extends the possibilities of future pelvimetry research using 3DTUS.

Risk of malignancy in women who underwent hysterectomy for uterine prolapse.

AIMS: To evaluate the risk of missing a malignancy in surgical specimens following hysterectomy for uterine prolapse if routine pathological examination is not performed. Additionally, information on the risk of missing an hitherto unsuspected malignancy if uterine preservation is the preferred management option will be provided. MATERIALS AND METHODS: A retrospective study was performed on all cases of surgery performed for uterine prolapse in a tertiary referral institution from 2003 to 2011. Those with confirmed malignancy before operation were excluded. The study subjects had their clinical history, investigations, the type of operations and histopathology report analysed. They were classified into symptomatic or asymptomatic, depending on whether they reported symptoms that were suggestive of uterine malignancy. RESULTS: A total of 640 women were studied. Three cases of hitherto unsuspected uterine malignancy were found, giving an incidence of 0.47%. Among the 456 asymptomatic women, both pre- and postmenopausal, the risk of incidental malignancy was 0.22%. Within the postmenopausal group, risk of incidental malignancy was 0.26%. Another 3 cases of uterine premalignant conditions were identified, giving an overall risk of premalignant and malignant uterine condition of 0.94%. Five cases of cervical intra-epithelial neoplasia were found, contributing to a risk of 0.78%. CONCLUSIONS: The risk of missing an uterine malignancy in patients with uterine prolapse is low if appropriate investigations are carried out prior to surgery. If hysterectomy is to be performed, we recommend that all surgical specimens be subjected to histopathological examination.

Pelvic floor muscle training improves quality of life of women with urinary incontinence: a prospective study.

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.

Tension-free vaginal mesh for the treatment of pelvic organ prolapse in Chinese women.

OBJECTIVE: To assess perioperative and short-term outcomes after tension-free vaginal mesh repair of pelvic organ prolapse in local Chinese women. DESIGN: Case series. SETTING: The urogynaecology unit of a university teaching hospital in Hong Kong. PATIENTS: All women with stage III or more pelvic organ prolapse who underwent tension-free vaginal mesh repair with or without vaginal hysterectomy from May 2007 to June 2011. MAIN OUTCOME MEASURES: Perioperative and short-term outcomes. RESULTS: In all, 47 women underwent the procedure during the study period. The mean operating time was 94 minutes, the mean estimated blood loss was 163 mL, and the mean hospital stay was 4 days. Four patients had visceral injuries, all of which were identified and repaired during the operation; all four patients recovered uneventfully. The mean duration of follow-up was 25 (standard deviation, 13) months. Pelvic organ prolapse quantification improved significantly; nine (19%) of the patients had recurrent stage II prolapse but only one was symptomatic, six (13%) had postoperative mesh exposure, three of whom underwent mesh excision. There were five (11%) who had de-novo urodynamic stress incontinence, which was mostly mild and managed conservatively. Overall 91% (43/47) were satisfied with their operative outcome. CONCLUSIONS: The success rate of tension-free vaginal mesh repair for the treatment of pelvic organ prolapse in local Chinese women was comparable to rates reported internationally. There was a high degree of subjective satisfaction with the procedure. There were low rates of mesh exposure and de-novo stress incontinence that was mostly asymptomatic or mild.

Patterns of pediatric and adolescent female genital inflammation in China: an eight-year retrospective study of 49,175 patients in China.

Background: Genital inflammation is one of the most frequent clinical complaints among girls, which was easily overlooked by the general public. This study aimed to investigate the patterns and epidemiological characteristics of pediatric and adolescent female genital inflammation in China. Methods: A retrospective observational study (2011 to 2018) was conducted among all female patients under the age of 0-18 years at the Department of Pediatric and Adolescent Gynecology of The Children's Hospital, Zhejiang University School of Medicine. Data were collected from the electronic medical records. The abnormal vaginal discharge of patient was collected for microbiological investigation by bacterial and fungal culture. Descriptive analysis was conducted to evaluate the genital inflammation pattern and epidemiological characteristics, including age, season, and type of infected pathogens. Results: A total of 49,175 patients met the eligibility criteria of genital inflammation and 16,320 patients later came to the hospital for follow-up over the study period. The number of first-visit increased gradually from 3,769 in 2011 to 10,155 in 2018. The peak age of the first visit was 0-6 years old. Non-specific vulvovaginitis, lichen sclerosis, and labial adhesion were the top three genital inflammation. Among the top five potential common pathogens of vaginal infection, the prevalence of Haemophilus influenzae cases was the highest (31.42%, 203/646), followed by Streptococcus pyogenes (27.74%, 176/646), Candida albicans (14.09%, 91/646), Escherichia coli (8.51%, 55/646), and Staphylococcus aureus (6.35%, 41/636).

Symptoms, quality of life, and factors affecting women's treatment decisions regarding pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: We performed an investigation of symptoms, quality of life (QOL), and factors affecting women's treatment choice of pelvic organ prolapse (POP). METHODS: Three hundred and eight women presenting with POP were assessed by Pelvic Floor Distress Inventory (PFDI), Pelvic Floor Impact Questionnaire (PFIQ), Short Form-36 (SF-36), Pelvic Organ Prolapse Quantification (POP-Q) system, and urodynamic studies. Treatment was arranged according to each woman's preference after counseling. Factors affecting treatment choice were evaluated. Descriptive statistics, chi-square or Fisher exact test, analysis of variance (ANOVA) test, and logistic regression analysis were used. RESULTS: Patients had high prevalence of urinary, prolapse, and bowel symptoms. Their QOL was impaired, with Urinary Impact Questionnaire (UIQ) higher than the Pelvic Organ Prolapse Impact Questionnaire (POPIQ) score and lower SF-36 score compared with the population norm. Logistic regression analysis indicated that complication from vaginal pessary, urodynamic stress incontinence (USI), stage of prolapse, and Pelvic Organ Prolapse Distress Inventory (POPDI) scoring were factors for choosing surgical treatment. CONCLUSIONS: Women with POP had great symptomatic distress and impaired QOL. Complication from vaginal pessary, USI, stage of prolapse, and POPDI scores were factors increasing the likelihood of the patient choosing surgical treatment.
