RESUMEN
The purposes of the investigation were to examine the implications of long noncoding RNA growth arrest-specific transcript 5 (GAS5) in progression and clinicopathological factors of uterine cervical cancer, and patient survival in Taiwan. Genotypic distributions of two GAS5 genetic variants rs145204276 and rs55829688 were detected in 208 patients including 111 patients with invasive cancer, 97 with precancerous lesions as well as 307 control women using real-time polymerase chain reaction. It explored that patients with cervical precancerous lesion had lower rate of AGGCA deletion (Del) in both alleles (Del/Del) of GAS5 rs145204276 as compared with control women. Patients with invasive cancer did not exhibit higher rate of Del/Del. Meanwhile, there were no different genotypic distributions in rs55829688 among patients with cervical invasive cancer and those with precancerous lesions as well as control women. Moreover, cervical cancer patients with Ins (insertion, AGGCA)/Del and Del/Del (-/-) in GAS5 rs55829688 tended to have poorer hazard ratio (HR) of 5 years survival. In addition, lymph node metastasis status exerted the most significantly predictive of 5 years survival rate. Conclusively, GAS5 polymorphism rs145204276 is probably applicable to predict 5 years survival HR of cervical cancer patients. However, the mechanism elucidating the methylation status and transcription function of rs145204276 in uterine cervical cancer needs to be delineated for its unique implication in uterine cervical cancer.

The objectives of this study were to define the associations among single nucleotide polymorphisms (SNPs) of metastasis-associated in colon cancer-1 (MACC1) gene, development and clinicopathological characteristics of uterine cervical cancer, and patient survival in Taiwan. Genotypic frequencies of 5 MACC1 SNPs rs975263, rs3095007, rs4721888, rs3735615 and rs1990172 were identified for 132 patients with invasive cancer, 99 with high-grade cervical intraepithelial neoplasia and 338 normal controls using real-time polymerase chain reaction. It revealed that there were no associations of these MACC1 SNPs with cervical carcinogenesis. In the meantime, cervical cancer patients with genotype GG in MACC1 SNP rs975263 tended to display more risk to have vaginal invasion than those with AA/AG (p=0.042, OR: 8.70, 95% CI: 0.81-433.22). In multivariate analysis, positive pelvic lymph node metastasis could significantly predict worse 5 years survival rate (p=0.001; HR=9.98, 95% CI=2.64-37.77) for cervical cancer patients. In conclusion, pelvic lymph node status rather than MACC1 SNPs was the only independent parameter that could significantly predict 5 years survival rate in Taiwanese women with cervical cancer.

AIMS: The direct cost of operations and health care expenditure for treating pelvic floor dysfunction are substantial. In this study, we evaluate the number of inpatient surgical procedures and direct expenditures for treating pelvic organ prolapse and urinary incontinence under the coverage of National Health Insurance (NHI) in Taiwan. METHODS: Thirteen years of population-based NHI inpatient claims were used in this study. The number of surgical procedures and the average direct cost of inpatient fees for treating pelvic floor dysfunction for each patient from 1999 to 2011 were calculated. The patients were stratified based on age into a younger than 65 years group and 65 years or older group for comparisons. RESULTS: The number of patients per year increased by 27%, increasing from 5278 patients in 1999 to 6706 patients in 2011. The total direct cost of inpatient (surgical and admission) fees for pelvic floor dysfunction increased by 57.2%, increasing from $6 674 968 USD in 1999 to $10 494 894 USD in 2011. However, while the expenditures for women 65 years or older increased by 102.2% from 1999 to 2011, there was only a 38.3% increase for those younger than 65 years when we stratified the patients by age. CONCLUSION: The increasing expenditures for inpatient surgery for pelvic floor dysfunction are mainly due to the escalating utilization of inpatient surgical procedures, especially those for pelvic organ prolapse in women aged 65 or older.

The purposes of this study were to examine whether there were associations among matrix metalloproteinase-11 (MMP-11) gene polymorphisms, development and clinicopathological characteristics of uterine cervical cancer as well as patient survival or not. Five single-nucleotide polymorphisms (SNPs) of the MMP-11 gene rs738791, rs738792, rs2267029, rs28382575, and rs131451 from one hundred and thirty patients with invasive cancer, 99 patients with high-grade cervical intraepithelial neoplasia (CIN) of uterine and 335 normal controls were analyzed using real-time polymerase chain reaction. Our results revealed that genotypic frequencies of CT/TT in MMP-11 SNP rs738791, with CC as a reference, tended to exhibit significantly different distributions (p=0.044, AOR: 0.63, 95% CI: 0.41-0.99) between patients with cervical invasive cancer and normal control women when controlling age. After multiple significance adjustment, the tendency becomes insignificant (Holm's adjusted p 0.176). Although CT/TT genotype of MMP-11 gene rs738791 tended to increase the risk of developing stage II disease at least (p=0.035; OR: 2.16, 95% CI: 1.05-4.44) and deep stromal invasion more than 10 mm (p=0.043; OR: 2.08, 95% CI: 1.02-4.26) with CC as a reference in patients with uterine cervical cancer. They became insignificant after multiple significance adjustment and the Holm's adjusted p values would become as 0.245 and 0.258, respectively. However, lymph node metastasis exhibited significant worse recurrence-free survival (p=0.033; HR: 2.83, 95% CI: 1.09-7.35), and overall survival (p=0.001; HR: 4.80, 95% CI: 1.82-12.62) compared to those without pelvic lymph node metastasis. In conclusion, it indicates no impact of the MMP-11 SNPs on uterine cervical cancer in Taiwanese women.

OBJECTIVE: In this 3-year longitudinal cohort study, we aimed to evaluate the evolution of overactive bladder in female community residents aged 40 years and above in central Taiwan and identify its risk factors. MATERIALS AND METHODS: Female community residents aged 40 years and above were invited to participate in this study and fill out a yearly Overactive Bladder Symptom Score (OABSS) questionnaire over a 3-year period. A woman was defined to have OAB if the total OABSS was â§4 and urgency score was â§2. At the end of the third year, the incidence, remission, persistence, and relapse of OAB in these community residents were calculated. A novel statistical analysis technique, machine learning with data mining, was applied to examine its use in this field. Five machine learning models were used to predict the risk factors associated with persistent OAB and the results were compared with the conventional logistic regression model. RESULTS: In total, 1469 female residents were included in the first year and 1290 (87.8%) women completed the questionnaires for all 3 years. The prevalence of OAB was 20.2% (n = 260). The second- and third-year incidence rates of OAB were 13.5% and 7.1%. The remission rates were 39.6% and 44.3%. Twenty-two percent of the women reported relapse of OAB in the third year. The two-year OAB persistence rate was 43.8%. For the prediction of risk factors for persistent OAB, the multivariable logistic regression model had better predictive accuracy (AUC = 0.664) than the five machine learning models. Age ⧠60 was associated with persistent OAB (OR 2.8; 95% CI: 1.34-5.89, P = 0.002). CONCLUSION: The yearly incidence, remission, and persistence rates of OAB were high in female community residents aged 40 years and above in central Taiwan. Older women had a higher risk of persistent OAB symptoms in this 3-year longitudinal cohort study.

OBJECTIVE: Relationships between pelvic organ prolapse (POP) staging and lower urinary tract symptoms (LUTS) are controversial. In this study, we evaluated correlations of POP staging with LUTS in different compartments. MATERIALS AND METHODS: From January 2016 to December 2017, 250 consecutive patients with urogynecologic complaints who were referred to our urodynamic unit were recruited into this study. Different stages of different compartments (anterior, central and posterior) of POPs according to IUGA and ICS terminology were re-grouped into four categories as stage 0, 1, 2, and 3 (including stage 4 because of a limited number of patients in stage 4). Pearson correlation coefficient and general linear regression were used for correlations of POP staging in different compartments and LUTS (stress urinary incontinence, overactive bladder and voiding symptoms) as well as their associated factors. RESULTS: Only OAB had a moderate correlation with different compartments of POP (anterior vaginal wall: -0.3116; cervix: -0.2954 and posterior vaginal wall: -0.3779; all p < 0.05). Stage 1 AVWP significantly increased (39.6%) the occurrence of OAB compared to no prolapse. Posterior compartment (stage 1-3) prolapse reduced the occurrence of OAB. CONCLUSION: Only stage 1 AVWP is associated with an increase in OAB, and posterior compartment prolapse may reduce the occurrence of OAB.

OBJECTIVE: Previous studies have shown that anterior vaginal wall prolapse (AVWP) results in reduction of pressure in the proximal urethra. However, the effect of severity of AVWP on urethral pressure is controversial. This study aimed to evaluate parameters of the urethral pressure profile in different stages of AVWP. MATERIALS AND METHODS: From 2016 to 2017, 286 consecutive patients with urogynecologic complaints who were referred to our urodynamic unit were enrolled in this study to analyze their urethral pressure profiles. Stages of AVWP were regrouped into three groups ranging from mild to severe stages (groups 1-3). Maximal urethral pressure, urethral closure pressure, functional urethral length, length of continence zone, as well as area of continence zone were compared among these three groups. RESULTS: Distribution of age, parity, and menopausal women were significantly different among these three groups. Maximal urethral pressure (pressures for groups 1, 2, and 3 were 74.6â¼75.9cmH2O, 69.7â¼73.4cmH2O, and 58.3â¼60.5cmH2O, respectively; all P<.05) and stress urethral closure pressure (pressures for groups 1, 2, and 3 were 69.3cmH2O, 62.3cmH2O, and 52.2cmH2O, respectively; all P<.05) gradually and significantly decreased, consistent with the severity of AVWP. However, the attenuated maximal urethral pressure and stress urethral closure pressure in accordance with severity did not show any significant difference after controlling for age, body mass index, parity, menopause, and stress urinary incontinence symptoms. CONCLUSION: Our results showed that AVWP significantly attenuated urethral pressure. However, patient age, menopausal status, and number of parities seem to be more influential in compromising urethral function than just AVWP alone.

OBJECTIVES: To evaluate the short-term evolution and risk factors of overactive bladder (OAB) in community-dwelling male residents aged 40 years and above in central Taiwan. METHODS: This was a 3-year longitudinal cohort study. From January 2012 to December 2012, community residents aged 40 years and above, living in central Taiwan, were invited to participate in this study. A yearly Overactive Bladder Symptom Score (OABSS) questionnaire was used to assess the prevalence, incidence, remission, persistence, and relapse of OAB for three consecutive years. OAB was defined as total OABSS â§4 and urgency score â§2. RESULTS: Nine hundred forty-one male residents aged â§40 years were recruited. The prevalence of OAB was 15%. The male residents with OAB were older, had a history of urological surgery, were unemployed, had lower educational levels, and lower yearly incomes compared with male residents without OAB. The prevalence increased with age when stratified into different age cohorts (40-49, 7%; 50-59, 12.7%; 60-69, 18.2%; â§70, 32%; P < .001). Age â§60 (odds ratio [OR] 2.58; 95% CI, 1.62-4.11) and history of urological surgery (OR 2.85; 95% CI, 1.29-6.30) were the major risk factors after multivariable logistic regression analysis. Eight hundred participants completed all the 3 years' questionnaires. The second- and third-year incidence rates of OAB were 10% (69/691) and 6.2% (42/674), respectively. The remission rates were 47.7% (52/109) and 46% (58/126), respectively. The two-year OAB persistence rate was 30.3% (33/109). CONCLUSIONS: The prevalence and yearly incidence of OAB are high in community-dwelling male residents aged â§40 years in central Taiwan. Age is an important risk factor.

OBJECTIVE: To evaluate the short-term effect of routine early postpartum electromyographic biofeedback assisted pelvic floor muscle training on sexual function and lower urinary tract symptoms. MATERIALS AND METHODS: From December 2016 to November 2017, primiparous women with vaginal delivery, who experienced non-extended second-degree perineal laceration were invited to participate. Seventy-five participants were assigned into a pelvic floor muscle training (PFMT) group or control group. Women in the PFMT group received supervised biofeedback-assisted pelvic floor muscle training at the 1st week and 4th week postpartum. Exercises were performed at home with the same protocol until 6 weeks postpartum. The Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Urinary Distress Inventory short form questionnaire (UDI-6) were used to evaluate sexual function and lower urinary tract symptoms respectively at immediate postpartum, 6 weeks, 3 months, and 6 months postpartum. RESULTS: Forty-five women (23 in PFMT group,22 in control group) completed all questionnaires at 6 months postpartum. For overall sexual function and the three sexual functional domains, no statistically significant difference was found in PISQ scores from baseline to 6 weeks, 3 months, and 6 months postpartum between the PFMT and control groups. For postpartum lower urinary tract symptoms, all symptoms gradually improved over time for both groups without a statistically significant difference between groups. CONCLUSION: Our study showed that supervised biofeedback-assisted pelvic floor muscle training started routinely at one week postpartum did not provide additional improvement in postpartum sexual function and lower urinary tract symptoms.

Many epigenetic regulators are involved in pain-associated spinal plasticity. Coactivator-associated arginine methyltransferase 1 (CARM1), an epigenetic regulator of histone arginine methylation, is a highly interesting target in neuroplasticity. However, its potential contribution to spinal plasticity-associated neuropathic pain development remains poorly explored. Here, we report that nerve injury decreased the expression of spinal CARM1 and induced allodynia. Moreover, decreasing spinal CARM1 expression by Fbxo3-mediated CARM1 ubiquitination promoted H3R17me2 decrement at the K+ channel promoter, thereby causing K+ channel epigenetic silencing and the development of neuropathic pain. Remarkably, in naïve rats, decreasing spinal CARM1 using CARM1 siRNA or a CARM1 inhibitor resulted in similar epigenetic signaling and allodynia. Furthermore, intrathecal administration of BC-1215 (a novel Fbxo3 inhibitor) prevented CARM1 ubiquitination to block K+ channel gene silencing and ameliorate allodynia after nerve injury. Collectively, the results reveal that this newly identified spinal Fbxo3-CARM1-K+ channel gene functional axis promotes neuropathic pain. These findings provide essential insights that will aid in the development of more efficient and specific therapies against neuropathic pain.

ABSTRACT: Mixed lineage leukemia 1 (MLL1)-mediated histone H3 lysine 4 trimethylation (H3K4me3) of a subset of genes has been linked to the transcriptional activation critical for synaptic plasticity, but its potential contribution to neuropathic allodynia development remains poorly explored. Here, we show that MLL1, which is induced in dorsal horn neuron after spinal nerve ligation (SNL), is responsible for mechanical allodynia and increased H3K4me3 at metabotropic glutamate receptor subtype 5 (mGluR5) promoter. Moreover, SNL induced WD (Trp-Asp) repeat domain 5 subunit (WDR5) expression as well as the MLL1-WDR5 interaction accompany with H3K4me3 enrichment and transcription of mGluR5 gene in the dorsal horn in neuropathic allodynia progression. Conversely, WDR5-0103, a novel inhibitor of the MLL1-WDR5 interaction, reversed SNL-induced allodynia and inhibited SNL-enhanced mGluR5 transcription/expression as well as MLL1, WDR5, and H3K4me3 at the mGluR5 promoter in the dorsal horn. Furthermore, disrupting the expression of MLL1 or WDR5 using small interfering RNA attenuated mechanical allodynia and reversed protein transcription/expression and complex localizing at mGluR5 promoter in the dorsal horn induced by SNL. This finding revealed that MLL1-WDR5 complex integrity regulates MLL1 and WDR5 recruitment to H3K4me3 enrichment at mGluR5 promoter in the dorsal horn underlying neuropathic allodynia. Collectively, our findings indicated that SNL enhances the MLL1-WDR5 complex, which facilitates MLL1 and WDR5 recruitment to H3K4me3 enrichment at mGluR5 promoter in spinal plasticity contributing to neuropathic allodynia pathogenesis.

OBJECTIVE: To evaluate the long-term subjective outcomes in women who underwent sacrospinous ligament fixation with and without uterine preservation for treatment of uterovaginal prolapse. STUDY DESIGN: Two hundred and ten women with POP-Qâ§stage III uterovaginal prolapse, who underwent sacrospinous ligament fixation from January 1994 to December 2007 were included. Patient Global Impression of Improvement was used to assess the surgical outcome in July 2016. Primary outcome measures were subjective success rate and current satisfaction. Kaplan-Meier method and Cox proportional hazard model were used for analysis. RESULTS: The mean follow-up was 13.3 years (range 8.5-22.6 years). One hundred and thirty-nine patients were successfully interviewed and analyzed. The cumulative subjective success rate was 88.5% and current satisfaction was 77.7%. The repeat surgery rate was 2.9%. There were no significant differences in subjective success (89% vs. 88%) or current satisfaction (78.1% vs. 77.3%) between uterine preservation (nâ¯=â¯64) and concomitant hysterectomy (nâ¯=â¯75). Kaplan-Meier analysis showed that sacrospinous ligament fixation with uterine preservation had a better subjective outcome at mid-term follow-up but was not significantly different compared with concomitant hysterectomy after long-term follow-up (Pâ¯=â¯0.63). The adjusted HR of uterine preservation was 0.75 (95%CI: 0.22-2.12, Pâ¯=â¯0.59). CONCLUSION: Sacrospinous ligament fixation with or without uterine preservation in the treatment of women with uterovaginal prolapse has no significant difference in long-term subjective outcomes and patient satisfaction.

OBJECTIVE: To evaluate the effect of far-infrared radiation on postpartum perineal pain and sexual function in primiparous women undergoing an episiotomy and 2nd degree perineal laceration. MATERIALS AND METHODS: From May 2016 to May 2017, primiparous women with term pregnancies and vaginal deliveries with an episiotomy due to obstetric indications and 2nd degree perineal lacerations were invited to participate in this study. Women were randomly assigned into a far-infrared (FIR) group and a control group. Visual Analogue Scale (VAS) was used to evaluate the perineal pain immediately postpartum, and at 1 week and 6 weeks postpartum. Pelvic Organ Prolapse Urinary Incontinence Sexual Questionnaire (PISQ-12) was used to evaluate sexual function at 6 weeks, 3 months and 6 months postpartum. RESULTS: The data of the control group (n = 22) and FIR group (n = 18) were analyzed. Most of the women had minor perineal pain one week after delivery (1.1 ± 0.9 in control group vs 1.4 ± 1.5 in FIR group) and there was no significant difference between groups. The FIR group had a higher PISQ-12 total score at 3 months (35.4 ± 6.4 vs 34.7 ± 5.7) and 6 months (36.4 ± 5.6 vs 35.6 ± 5.7) postpartum compared with the control group but there was no statistically significant difference. CONCLUSION: Our study did not show any additional benefit of postpartum far-infrared radiation on primiparous women undergoing an episiotomy and 2nd degree perineal lacerations.

The purposes of the current study were conducted to explore the relationships among long non-coding RNA gene H19 (LncRNA H19) polymorphisms and clinicopathological characteristics of uterine cervical cancer, and patient prognosis in Taiwan. Five genetic variants of LncRNA H19 rs3024270, rs2839698, rs3741219, rs2107425 and rs217727 were recruited from one hundred and thirty-four patients with invasive cancer, 101 with high-grade cervical intraepithelial neoplasia (CIN) of uterine cervix and 325 controls and their genetic distributions were determined. It indicated no associations of these LncRNA H19 genetic variants with development of cervical cancer. CC/CT in LncRNA H19 rs2839698 exhibited less risk to have pelvic lymph node metastasis [Odds ratio (OR): 0.19, 95% Confidence interval (CI):0.04-0.82, p=0.028)], as compared with TT. Meanwhile, cervical cancer patients with AA/AG in rs3741219 also had less risk to develop pelvic lymph node metastasis (OR: 0.17, 95% CI: 0.05-0.63, p=0.008), large tumor (OR: 0.17, 95% CI: 0.04-0.82, p=0.014) as well as parametrium (OR: 0.26, 95% CI: 0.07-0.95, p=0.045) and vagina invasion (OR: 0.25, 95% CI: 0.07-0.91, p=0.041, as compared to those with GG. However, only positive pelvic lymph node metastasis was related to worse recurrence-free survival and poor overall survival. Conclusively, it indicated no association of LncRNA H19 SNPs with cervical carcinogensis in Taiwanese women. Although genotypes TT in LncRNA H19 rs2839698 and GG in rs3741219 are related to some poor clinicopathological parameters of cervical cancer, only pelvic lymph node status could predict 5 year patient survival significantly.
RESUMEN
To date, few studies explore the involvement of endothelial nitric oxide synthase (eNOS) gene variants in uterine cervical cancer. Therefore, we conducted this study to assess the clinical implication of eNOS in cervical carcinogenesis, clinicopathological characteristics and patient survival. One hundred and seventeen patients with cervical invasive cancer and 95 with preinvasive lesions and 330 control women were consecutively enrolled. Real time polymerase chain reaction was used to examine the genotypic distributions of eNOS single nucleotide polymorphisms (SNPs) rs1799983 (894G>T) at the exon 7 region and rs2070744 (-786T>C) at the promoter region. Our results indicated no significant associations among genotypic distributions of eNOS SNPs and patients with cervical invasive cancer and those with preinvasive lesions as well as normal controls. However, cervical cancer patients with genotypes TC/CC in eNOS SNP rs2070744 carried less risk of advanced stage [odds ratios (OR) = 0.30, 95% confidence interval (CI)=0.09-0.97, p=0.036], parametrium invasion (OR=0.16, 95% CI=0.02-0.75, p=0.009) and pelvic lymph node metastasis (OR=0.12, 95% CI=0.01-0.89, p=0.016). In conclusion, although eNOS SNPs rs2070744 and rs1799983 do not display significant associations with cervical carcinogenesis and patient survival, cervical cancer patients with genotypes TC/CC in rs2070744 carry less risk of advanced stage, parametrium invasion and pelvic lymph node metastasis in Taiwan.
RESUMEN
To date, few studies have explored the effects of single nucleotide polymorphisms (SNPs) of the receptor for advanced glycation end products (RAGE) in uterine cervical cancer. Therefore, we conducted this study to investigate the involvement of RAGE SNPs in cervical cancer. In total, 117 patients with cervical invasive cancer, 84 with precancerous lesions, and 320 normal women were recruited consecutively. Real-time polymerase chain reaction was used to examine the genotypic frequencies of RAGE SNPs. The results indicated that among the four RAGE SNPs, only the GT/TT genotype of rs184003 was distributed differently between patients with cervical neoplasias and the normal controls, with GG as a reference. Moreover, cervical cancer patients with genotypes TA/AA in rs1800624 exhibited a lower risk of parametrium invasion, moderate-to-poor cell differentiation, and pelvic lymph node metastasis. In conclusion, RAGE SNPs rs1800624 was associated with some clinicopathological variables in cervical cancer.
RESUMEN
OBJECTIVE: This is part of a three-year study designed to evaluate the natural history of lower urinary tract symptoms in local community residents aged 40 years and above in central Taiwan. We evaluated the prevalence of overactive bladder (OAB) and voiding dysfunction (VD) in female residents using validated questionnaires. MATERIALS AND METHODS: A structured questionnaire containing groups of different questionnaires was translated into Chinese and each one was validated separately. A trained research assistant interviewed the participants and assisted in filling in the questionnaires. Residents were recorded to have OAB if the total OABSS score wasâ§4. Urge urinary incontinence (UUI) was defined as urine leakage preceded by the feeling of urgency which is slightly or more distressful. VD was defined as feeling of difficulty in emptying the bladder which is slightly or more distressful. RESULTS: A total of 2411 community residents aged 40 years and above who completed all the questionnaires in the initial survey were recruited, of which 1469(60.9%) were women. The prevalence of OAB, UUI and VD were 33.1%, 26.8% and 28.3% respectively in the female community residents. Ageâ§60 (OR, 1.5; 95%CI, 1.1-2.0), menopause (OR1.4; 95% CI, 1.0-1.9) and a history of diabetes mellitus (OR, 1.8; 95% CI, 1.2-2.8) were the risk factors for OAB. Ageâ§60 (OR, 1.4; 95%CI, 1.0-1.9), BMI â§25 (OR, 1.3; 95% CI, 1.0-1.7) and instrument deliveries (OR, 1.5; 95% CI, 1.0-2.1) were the risk factors for VD. CONCLUSION: Our results imply that the prevalence of overactive bladder and voiding difficulty are high in female community residents aged ⧠40 years in central Taiwan.

BACKGROUND: To determine if there are clinical and urodynamic (UD) differences between female overactive bladder (OAB) patients with bladder oversensitivity (BO) and detrusor overactivity (DO) via a much lower filling rate. METHODS: In total, 205 patients with OAB symptoms were recruited for this study. During filling cystometry, the bladder was filled at a more "physiological" rate of 20 ml/min. All patients underwent a complete urogynecological evaluation including detailed history, physical examination, urinalysis, pad test for quantification of urine leakage, 3-day frequency-volume chart (FVC) documentation, and completion of a UD study. RESULTS: The overall incidence of BO was 34.2% and that of DO was 65.8%. The first desire to void (FDV) in patients with BO and DO were at filling of 117.47 ± 21.68 ml and 135.23 ± 22.88 ml, respectively (p < 0.05). Maximal cystometric capacities (MCC) in patients with BO and DO were recorded at 259.44 ± 33.87 ml and 265.32 ± 44.05 ml (p > 0.05). A receiver operating characteristic (ROC) curve was used to find the cut-off values of FDV for sensitivity and specificity in patients diagnosed with DO. Area under the curve (AUC) was 0.702 (p < 0.005, 95% confidence interval: 0.626-0.779) if FDV was determined as more than 127 ml. Patients with BO experienced significantly increased daytime urinary frequency and nocturia symptoms (<0.05). Patients with DO had a significantly higher prevalence of urgent urinary incontinence (p < 0.05). In this study, a higher FDV and higher body mass index (BMI) were correlating factors for OAB patients with DO after multiple logistic regression analysis. CONCLUSION: Patients with BO seemed to be on a different spectrum compared to those with DO and also had different symptom-specific and associative factors. It was also found that FDV could be good predictive indicator for detecting DO at a low filling rate.

OBJECTIVE: Treatment of genital prolapse in elderly women is challenging. The aim of this study was to evaluate the long-term postoperative patient satisfaction and objective improvement in women aged 70 years and over with high stages of pelvic organ prolapse treated with obliterative LeFort colpocleisis. MATERIALS AND METHODS: From January 2003 to December 2013, female patients aged 70 years and over who underwent colpocleisis surgery were included in this study. We reviewed the charts for preoperative and postoperative medical history, severity of prolapse, urodynamic studies, and early postoperative complications related to this procedure in these patients. Subjective outcomes were assessed by a nursing coordinator who interviewed patients by telephone in June 2014. RESULTS: Colpocleisis was performed in 22 elderly patients and 59% patients were of advanced age (≥ 80 years). The mean postoperative follow-up duration was 48.1 months (range, 7-118) months. Six patients (27.3%) had died of medical problems at the time of the telephone interview. Fourteen patients (87.5%) reported a successful outcome after the operation and two patients (12.5%) reported improvement. For present satisfaction, 93.8% of patients reported that they were satisfied. CONCLUSION: Colpocleisis should be considered as one of the surgical options for treating advanced pelvic organ prolapse in elderly patients who do not wish to preserve vaginal function for sexual intercourse.
