Objective: To develop a scoring system to predict the likelihood of vaginal birth in patients undergoing a trial of labor after previous cesarean delivery. Methods: Variables influencing successful vaginal delivery rate were studied in 321 patients who had undergone a trial of labor after previous cesarean delivery from January, 1996 to December, 1998. Results: Totally, It resulted in a rate of vaginal birth after cesarean delivery of 70.1%. Six variables [maternal height, current fetal weight, prior vaginal delivery, indication for prior cesarean delivery, cervix dilatation in admission, head fixation] significantly affected a rate of successful vaginal birth after cesarean. Rate of successful vaginal birth after cesarean delivery was 27.5% in patients scoring less than or equal to 1, 95.1% in patients scoring greater than or equal to 4. Increasing score was associated with increasing vaginal delivery success rates. Conclusion: It is expected that the proposed scoring system will be helpful for perspective patients and doctors deciding mode of delivery.

Objective: To evaluate the perinatal outcome of vaginal delivery in twin pregnancy according to the presentation of the fetus. Methods: A total of 274 cases suitable to this objective were selected from the 301 cases of twin pregnancy delivered between March 2000 and February 2005. They were categorized into 3 groups according to the presentation of the fetus; vertex/vertex as the group A (133 cases), vertex/nonvertex as the group B (80 cases), nonvertex in the first twin as the group C (61 cases). And then each group also was divided into 2 subgroups according to the mode of delivery; vaginal delivery and cesarean delivery. The difference between the subgroups in each group as to perinatal outcome was retrospectively compared and analyzed for statistical significance. Results: The incidence of vaginal delivery in group A (46/133, 34.6%) was significantly higher than in group B (5/80, 6.3%) and C (5/61, 8.2%). A total of 218 (79.6%) cases were underwent the cesarean delivery and the most common indication of cesarean delivery was elective twin cesarean delivery in all 3 groups (65.4%, 93.8%, 91.8% respectively). The incidence of neonatal admission to the neonatal intensive care unit was, however, higher in vaginal delivery (40.2%) than in cesarean delivery (32.8%) in group A. The most common cause for neonatal intensive care unit admission was low birth weight for simple observation, and average admission dates of vaginal delivery was 17.0 days and cesarean delivery was 16.8 days. Conclusion: Vaginal delivery of twins depends on the presentation of the fetus, but no significant difference in perinatal outcome of group A were observed between the mode of delivery. Therefore attempt to decrease the incidence of elective twin cesarean delivery in group A is demanded.

Purpose: Low birth rate is one of the major social problems in Korea. This study is aimed atproviding Korea’s birth promotion policy with evidence derived from the analysis of the deliverydata available from the Health Insurance Review & Assessment Service (HIRA). Methods: We conducted an analysis on the characteristics of hospital admissions and dischargesby types of delivery using the data on claims for deliveries made to HIRA for the period of 2009to 2011. Results: Of all deliveries analyzed, 64.3% were normal spontaneous vaginal deliveries and 35.7%were deliveries by cesarean section, and among women above the age of 35, the higher the age,the higher the rate of women who had cesarean sections. On average, those who had vaginaldelivery were hospitalized for 3.3 days while those who had cesarean section were for 6.7 days. At hospital discharge, 90.1% of those who had vaginal delivery received medicine while 65.4% ofthose who had cesarean section did so. These findings were never mentioned in the previousstudies. 60% of those who had vaginal delivery were prescribed medicine for less than 3 days’use, while 49.3% of those who had cesarean section were given medicine for the same period. Interms of disease code classification, 83.3% of vaginal deliveries were categorized as single spontaneousdelivery (O80), and 49.2% of c-section deliveries were categorized as optional c-sectiondelivery with 35.7% as emergency c-section delivery. 72.7% of vaginal deliveries were includedin sub-diagnosis while 82.7% were included for cesarean section. As to the medical expensesincurred, the total medical fee and the co-payment by patients were ₩828,571 and ₩16,423 respectively for vaginal delivery and ₩1,173,769 and ₩235,522 respectively for cesarean sectionwith the expenses incurred for c-section were ₩345,198 higher for the total medical fee and₩219,099 higher for co-payment than for vaginal delivery. Conclusion: In conclusion, policy efforts should be made to support fertility raising, promotion ofvaginal delivery, and child care expansion, for example, a task force or a committee organized bythe government.

Objective The purpose of our study was to investigate the effect of the mode of delivery on the oxidant and antioxidant system in umbilical cord blood. Methods We performed gas analysis of umbilical venous blood and umbilical arterial blood immediately after delivery in 38 women; eighteen women had a vaginal delivery while 20 women delivered via cesarean section at over 37 weeks gestation. We examined lipid peroxide concentration by thiobarbituric acid reaction, protein carbonyl content by 2,4-dinitrophenylhydrazine reaction, and total antioxidant capacity by oxygen radical absorbance capacity assay. Results Lipid peroxide levels in umbilical venous blood were significantly higher in patients delivering by planned cesarean section (1.81 ± 0.06 nmol/mg protein) than those with vaginal delivery (1.24 ± 0.05 nmol/mg protein) ( P < 0.05). Antioxidant capacity in umbilical venous blood was significantly higher in patients delivering by planned cesarean section (119.70 ± 0.13 μM/μL) than those with a vaginal delivery (118.70 ± 0.29 μM/μL) ( P < 0.05). There was no significant difference in the carbonyl content of umbilical venous blood or in the lipid peroxide, carbonyl content, and total antioxidant capacity of umbilical arterial blood. Conclusion Lipid peroxidation levels and antioxidant capacity in umbilical venous blood were higher in patients delivering by planned cesarean section than those with a vaginal delivery. Therefore, we propose that both the mother and neonate are exposed to higher oxidative stress during cesarean section delivery.

Objective: The purpose of this study was to evaluate if the number of normal vaginal deliveries influences lower urogenital system function and the incidence of incontinence. Materials and methods: The POP-Q (Pelvic Organ Prolapse Quantitation) examination was performed in 217 premenopausal women who visited our hospital for routine check up. They were asked to fill in the Bristol female lower urinary tract symptom (BFLUTS) and self-report questionnaire for fecal incontinence and constipation assessment questionnaires. Exclusion criteria included patients with a history of pelvic surgery, BMI >25, chronic lung disease, cardiovascular disease, colon disease or smoking. Results: There was a significant difference between the vaginal delivery group and none vaginal delivery group in the point Aa, Ba, Ap, Bp and Tvl in POP-Q (P<0.05). The patients were classified into four groups (0, 1, 2, above 3) according to the number of vaginal deliveries, and the incidences of fecal incontinence were 4%, 29%, 32%, 26% in each group, respectively. The incidence of fecal incontinence was significantly lower (P<0.05) in those who did not deliver vaginally, while no difference was observed in the number of vaginal deliveries. The BFLUTS-IS (incontinence symptom) score was higher in the patients with higher number of vaginal deliveries (P<0.05). There were also more patients with sexual dysfunction as was shown by the BFLUTS-sex questionnaire (P<0.05) in those patients with higher number of vaginal deliveries. Conclusion: We observed that the number of vaginal delivery is significantly associated with the incidence of fecal and urinary incontinence, and also that it was a major cause of disorders of the pelvic floor and sexual dysfunction.

ObjectiveTo evaluate the efficacy and safety of prostaglandin (PG) E2 for preterm labor induction and to investigate the predictive factors for the success of vaginal delivery. MethodsA retrospective cohort study was performed in women (n=155) at 24+0 to 36+6 weeks of gestation who underwent induction of labor using a PGE2 vaginal pessary (10 mg, Propess) from January 2009 to December 2015. Success rates of vaginal delivery according to gestational age at induction and incidence of intrapartum complications such as tachysystole and nonreassuring fetal heart rate were investigated. Multivariable logistic regression analysis was performed to evaluate the predictive factors for success of labor induction. ResultsThe vaginal delivery rate was 57% (n=89) and the rate of cesarean delivery after induction was 43% (n=66). According to gestational age, labor induction was successful in 16.7%, 50.0%, and 62.8% of patients at 24 to 31, 32 to 33, and 34 to 36 weeks, showing a stepwise increase (P=0.006). There were 18 cases (11%) of fetal distress, 9 cases (5.8%) of tachysystole, and 6 cases (3.8%) of massive postpartum bleeding (>1,000 mL). After adjusting for confounding factors, multiparity (odds ratio [OR], 8.47; 95% confidence interval [CI], 3.10 to 23.14), younger maternal age (OR, 0.84; 95% CI, 0.75 to 0.94), advanced gestational age at induction (OR, 1.06; 95% CI, 1.02 to 1.09), rupture of membranes (OR, 11.83; 95% CI, 3.55 to 39.40), and the Bishop score change after removal of PGE2 (OR, 2.19; 95% CI, 1.0 to 4.8) were significant predictors of successful preterm vaginal delivery. ConclusionAn understanding of the principal predictive factors of successful preterm labor induction, as well as the safety of PGE2, will provide useful information when clinicians consult with preterm pregnant women requiring premature delivery.

Objective: The purpose of this study was to evaluate the risk of cesarean section in nulliparous women who undergone induction at postterm pregnancy. Methods : The retrospective study was conducted from March, 1997 to March, 2005 by reviewing 331 nulliparous patients more than 41 weeks` gestation delivered after induction at our Hospital. The evaluated variables to assess the risk of cesarean section were maternal age, body mass index (BMI), gestational age (GA), Bishop scores (BS), fetal body weight (FBW), fetal head circumference (FHC) and fetal sex. t-test and x2-test were used to compare these categorical variables. Results: The study included 331 nulliparous singleton pregnant women undergoing elective induction for postterm pregnancy: 127 (38.4%) delivered babies by cesarean section due to induction failure, progression failure and fetal distress, whereas 204 (61.6%) delivered vaginally. The mean maternal ages were 27.59±2.57 in cesarean delivery group and 26.99±2.61 in vaginal delivery group. The average values of BMI at postterm in cesarean and vaginal delivery groups were 26.70±2.82 and 25.75±2.67 kg/m2. GA was 41.36±0.27 weeks in cesarean delivery group, whereas 41.20±0.19 weeks in vaginal delivery group. The average FBW and FHC were 3460.31±358.22 g and 34.59±1.18 cm in cesarean delivery group, compared to 3363.95±361.22 g and 34.03±1.34 cm in vaginal delivery group. Conclusion : The BMI, FBW and FHC have linked to the risk of cesarean delivery in nulliparous women who underwent elective induction. Thus, these information would provide the useful tools to assess the risk of cesarean section in postterm nulliparous patients for planning an induction.

Purpose: The purpose of this study was to investigate of the effects of the mode of delivery on pelvic floor muscle function by examining bladder base movement and urinary incontinence. Methods: This study was conducted on 100 females who had delivered in the previous 3–8 months. There were 2 groups: 56 vaginal deliveries and 44 cesarean section deliveries. Prior to the study, a survey was conducted on the subjects’ general status, delivery mode, urinary incontinence, and physical activity. The groups could not be blinded due to scar tissue from the operations. The function of the pelvic floor muscle was observed with the bladder base movement using transabdominal ultrasound during pelvic floor contraction. To objectify and measure the subjective symptoms of subjects suffering from urinary incontinence, an incontinence quality of life (I-QoL) test was administered. Statistical analysis of the data was performed using SPSS version 20.0. An independent t-test was used to assess the statistical significance of pelvic floor muscle function between the 2 groups after delivery. Results: The movement of the bladder base in the pelvic floor muscle function was decreased in the vaginal delivery group, but the difference was not significant. Urinary incontinence was significantly increased in the vaginal delivery group. Conclusion: The function of the pelvic floor muscles was better in the cesarean section group and the incidence of urinary incontinence was relatively low in this group. Therefore, vaginal delivery requires more efforts to restore the function of the pelvic floor muscles than cesarean delivery.
