RESUMO
Purpose: In vitro maturation (IVM) of oocytes obtained from ovarian tissue during ovarian tissue cryopreservation (OTC) is a technique for fertility preservation in patients with cancer obviating the need to postpone chemotherapy initiation. Little is known about IVM outcomes in hematological malignancies, especially post-chemotherapy. The purpose of this study was to evaluate the effect of cytotoxic treatment on the potential to retrieve immature oocytes and mature them in vitro and examine the association between serum inflammatory markers and these results. Methods: In this retrospective study, we evaluated inflammation markers, including B symptoms and IVM outcomes of 78 chemotherapy-naive and exposed patients diagnosed with Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), or acute myeloid leukemia (AML). Results: The mean number of oocytes found was 7.2 ± 7.2. The average number of oocytes matured by IVM was 2.8 ± 3.5, and a mean IVM rate was 32.1 ± 27.7%. All patients in the ALL and AML groups had previous exposure to chemotherapy before OTC, compared with 50.0% (7/14) and 31.9% (15/47) in the NHL and HL groups, respectively. Among patients with lymphoma, chemotherapy exposure was associated with the reduced number of retrieved oocytes (9.8 ± 7.7 vs. 5.3 ± 5.7 oocytes, p = 0.049) in the HL group but not with the number of mature oocytes or IVM rate. B symptoms were not associated with IVM outcomes. Lymphocyte count (ß = 1.584; p = 0.038) and lactate dehydrogenase (ß = 0.009; p = 0.043) were the only significant parameters associated with the number of matured oocytes in a linear regression model. Conclusion: IVM is a promising assisted reproductive technology, which holds great potential for patients in need of urgent fertility preservation or those who cannot receive hormonal stimulation. Our results demonstrate the feasibility of the technique even in the presence of B symptoms and elevated inflammation markers and in patients with previous exposure to chemotherapy.
RESUMO
INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injury (OASI) is a major complication associated with vacuum-assisted vaginal delivery (VAVD). The aim of this study was to evaluate risk factors related to vacuum extraction that are associated with OASI. METHODS: This was a case-control study performed at a tertiary university teaching hospital. Included were patients aged 18-45 years who had a singleton pregnancy resulting in a live, term, VAVD. The study group consisted of women diagnosed with OASI following vacuum extraction. The control group included women following VAVD without OASI. Matching at a ratio of 1:2 was performed. Groups were compared regarding demographic, obstetric. and labor-related parameters, specifically focusing on variables related to the vacuum procedure itself. RESULTS: One hundred and ten patients within the study group and 212 within the control group were included in the final analysis. Patients in the OASI group were more likely to undergo induction of labor, use of oxytocin during labor, increased second stage of labor, higher likelihood of the operator being a resident, increased number of pulls, procedure lasting under 10 min, occipito-posterior head position at vacuum initiation, episiotomy, increased neonatal head circumference, and birthweight. Multivariate logistic regression analysis revealed that increased week of gestation (OR 1.67, 95% CI 1.25-2.22, p < 0.001), unsupervised resident performing the procedure (OR 4.63, 95% CI 2.17-9.90), p < 0.001), indication of VAVD being fetal distress (OR 2.72, 95% CI 1.04-7.10, p = 0.041), and length of procedure under 10 min (OR 4.75, 95% CI 1.53-14.68, p = 0.007) were associated with OASI. Increased maternal age was associated with lower risk of OASI (OR 0.9, 95% CI 0.84-0.98, p = 0.012). CONCLUSIONS: When performing VAVD, increased week of gestation, unsupervised resident performing the procedure, fetal distress as vacuum indication, and vacuum procedure under 10 min were associated with OASI. In contrast, increased maternal age was shown to be a protective factor.

OBJECTIVE: Endometriosis affects up to 10% of reproductive age women and is associated with pelvic pain and subfertility. While previous studies have shown an association between deep and ovarian endometriosis to reduced ovarian reserve, there is no data on the effect of superficial endometriosis on ovarian reserve markers. Hence, we aimed to compare ovarian reserve markers of women with superficial endometriosis to that of women without endometriosis. METHODS: This was a case control study in a tertiary medical center. The study group included women aged 18-40 with surgically and histopathology-proven superficial endometriosis with no deep lesions or ovarian involvement. The control group included women with no known or suspected endometriosis and was matched to the study group by age, BMI and parity. We excluded women with other known risk factors for ovarian failure and with other gynecological disorders. Participants completed a questionnaire with demographic, medical and gynecological data. Each patient underwent anti-Mullerian hormone (AMH) testing and an ultrasound to assess their antral follicular count (AFC). AMH and AFC were then compared between groups. RESULTS: A total of 124 women participated in the study. Of these, 50% (n = 62) had surgically proven superficial endometriosis and 50% (n = 62) were without known or suspected endometriosis. Mean AMH levels of women with and without superficial endometriosis was 3.0 ± 2.8 ng/mL and 2.8 ± 1.9 ng/mL, respectively (P = 0.71). AFC also did not differ between groups (women with superficial endometriosis: 12.0 ± 6.6; women without endometriosis: 10.2 ± 5.0, P = 0.15). CONCLUSIONS: In our cohort, superficial endometriosis was not associated with diminished ovarian reserve. While further studies are needed, to date, it does not appear to be justified to assess ovarian reserve for patients with superficial endometriosis.

BACKGROUND: Trial of labor after cesarean delivery (TOLAC) in twin gestations has been associated with decreased rates of successful vaginal delivery compared to singleton pregnancies, with mixed results regarding maternal and neonatal morbidity. However, induction of labor (IOL) in this unique population has not yet been fully evaluated. OBJECTIVE: To assess success rates and maternal and neonatal outcomes in women with a twin gestation and a previous cesarean delivery undergoing IOL. METHODS: A retrospective cohort study including women with a twin gestation and one previous cesarean delivery undergoing a trial of labor between the years 2009-2020. Patients requiring IOL were compared to those with a spontaneous onset of labor. RESULTS: There were 53 patients who met the inclusion criteria: 31 had a spontaneous onset of labor (58%) and 22 required an IOL. Baseline characteristics were comparable between the groups apart from a history of labor arrest which was more common in the IOL group (40.9% vs. 9.6%, P = 0.006). A successful vaginal delivery occurred in all (100%) women with a spontaneous labor compared to 81% in the IOL group (p = 0.02). Secondary outcomes were comparable. A history of no previous vaginal delivery, maternal obesity, and IOL were associated with TOLAC failure. CONCLUSIONS: IOL after cesarean delivery in twin gestation is associated with an increased risk of TOLAC failure compared to spontaneous onset of labor. However, no adverse neonatal or maternal outcomes were found. IOL in this high-risk population is feasible but patients should be counseled about the lower rate of success.

PURPOSE: The number of elderly patients bothered by pelvic organ prolapse symptoms is growing rapidly. The aim of this study was to evaluate the relationship between age and surgical outcomes in women undergoing uterosacral ligament suspension for treatment of apical prolapse. METHODS: We performed a retrospective cohort study including women who underwent uterosacral ligament suspension between 2010 and 2020. The cohort was divided into two groups: (1) Patients 70 years or older; (2) Patients under the age of 70. Outcome measures included clinical, anatomical, and composite outcomes as well as patient satisfaction. RESULTS: A total of 271 patients were included in the final analysis. Of them 209 patients were under age 70 and 62 patients 70 years or older. Mean age was 59 ± 6 vs. 73 ± 3 for the young and elderly age groups, respectively. Clinical success was high for both groups, reaching 94% vs. 89% for elderly and young patients, respectively (p = 0.34). Anatomical and composite outcome success were higher in the young age group (76% vs. 56%, p < 0.01 and 70% vs. 54%, p = 0.02, respectively); however, following multivariate analysis these differences were no longer statistically significant. Following multivariate logistic regression analysis for the dependent parameter of anatomical success, increased pre-operative genital hiatus and vaginal surgical route were associated with anatomical failure while performing a concomitant posterior colporrhaphy increased likelihood for anatomical success. CONCLUSION: Women over the age of 70 undergoing uterosacral ligament suspension for treatment of apical prolapse have comparable outcomes to younger patients.

OBJECTIVE: In recent years uterine preservation has become a popular option in women undergoing pelvic organ prolapse repair. The aim of this study was to evaluate the effect of uterine volume on outcomes following uterine preserving surgical treatment for apical prolapse. METHODS: We performed a retrospective comparative study at a tertiary university hospital. Included were women who had uterine preserving surgical treatment for apical prolapse. The cohort was divided into two groups: 1) Patients with a uterine volume ≥ 35 cm3 (large uterus group); 2) Patients with uterine volume < 35 cm3 (small uterus group). Pre-, intra-, and post-operative data were compared between groups. Our primary outcome was composite outcome success including clinical and anatomical success and no need for reoperation. Secondary outcomes included clinical success, anatomical success, and patient satisfaction evaluated using the PGI-I questionnaire. RESULTS: Eighty-four patients were included in the final analysis. The large uterus group (≥35 cm3) consisted of 37 patients as opposed to 47 in the small uterus group (<35 cm3). Clinical (91.9 % vs 87.1 %, p = 0.725) and anatomical success (84.8 % vs 90.9 %, p = 0.508) were high and did not differ between groups. Composite outcome success was 76.1 % in the small uterus group compared to 87.9 % in the large uterus group, but this difference was not statistically significant. Post-operative points Ba, C and Bp were similar between groups. No difference was found in patient satisfaction measured using the PGI-I questionnaire. CONCLUSION: Women undergoing uterine preserving apical prolapse repair with uterine volume ≥ 35 cm3 have comparable surgical outcomes to patients with a smaller uterus.

OBJECTIVES: To compare national and international guidelines regarding sentinel lymph node (SLN) mapping in endometrial cancer. METHODS: A descriptive comparative study of the National Comprehensive Cancer Network (NCCN), the Society of Gynecologic Oncology (SGO), the European Society of Gynecological Oncology (ESGO), the British Gynecological Cancer Society (BGCS), and the Japan Society of Gynecologic Oncology (JSGO) guidelines. RESULTS: There is a broad consensus that SLN mapping is an appropriate alternative to pelvic lymphadenectomy for uterine-confined endometrioid endometrial cancer (five of five guidelines). It is broadly accepted that a full lymphadenectomy should be performed in case of failed SLN mapping (four of five guidelines), and that mapping with the fluorescent dye indocyanine green is superior to other methods (four of five guidelines). It is agreed that the cervix is the preferable site for dye injection (four of five guidelines), and pathology ultrastaging is advocated by most guidelines (three of five guidelines). Regarding high-risk patients (i.e., high-grade histology and non-endometroid carcinomas), some guidelines accept (three of five), but others currently do not advocate (one of five guidelines), SLN mapping as a sole method for lymph node evaluation. There is no consensus regarding para-aortic lymph node evaluation in pelvic SLN-positive patients. CONCLUSION: Guidelines for SLN mapping are comparable with regards to surgical technique, ultrastaging, and management in case of failed mapping. Nevertheless, some variations exist regarding the management of high-grade histology and positive pelvic lymph nodes.

BACKGROUND: Induction of labor in women with a previous cesarean section (CS) is associated with increased rates of uterine rupture and failed attempt for vaginal delivery. Prostaglandins use is contraindicated in this population, limiting available options for cervical ripening. OBJECTIVE: To evaluate the efficacy and safety of artificial rupture of membranes (AROM) as a mode of Induction of labor (IOL) in women with a previous cesarean section. METHODS: A retrospective cohort study conducted in a single tertiary care center between January 2015 and October 2020. Women with one previous cesarean section and a current singleton term pregnancy requiring IOL, with an unfavorable cervix, were included. The primary outcome was a successful vaginal delivery (VBAC); secondary outcomes were rates of chorioamnionitis, uterine rupture and low Apgar score (< 7). RESULTS: Of the 665 women who met the inclusion criteria, 492 (74%) did not receive subsequent oxytocin and 173 (26%) did. There were significant differences in the baseline characteristics between these two groups, including maternal age, cervical dilation at presentation, parity, and a history of a previous VBAC. Among women who were induced solely by AROM the rate of a successful TOLAC was higher (81.3% vs 73.9%), total time of IOL was shorter (mean 8.7 h vs.16.1 h) and the risk of chorioamnionitis was lower (7.3% vs 18.4%). When subdividing the women who received oxytocin into early (< 12 h after AROM) vs late (> 12 h after AROM) administration, there were no significant changes in the rates of successful VBAC or of chorioamnionitis. CONCLUSION: AROM as a single mode of IOL in women with a previous CS is a safe and efficient practice with high rates of successful VBAC. When spontaneous labor does not develop, there is no advantage to delay the administration of oxytocin.

STUDY OBJECTIVE: The aim of this study was to evaluate the effect of age on outcomes after uterine-preserving surgical treatment for apical prolapse. DESIGN: Retrospective cohort study. SETTING: Female pelvic medicine and reconstructive surgery unit at a tertiary, university-affiliated teaching medical center. PATIENTS: Women who underwent surgical management of apical prolapse with uterine preservation between 2010 and 2020. Excluded were women who had ≤1 month of follow-up and those for whom medical records were substantially incomplete. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Included in the study were 140 women who underwent apical prolapse repair with uterine preservation and who met the inclusion criteria. The cohort was divided into 2 groups: (1) women aged 65 years and older (≥65 group) and (2) women younger than 65 years of age (<65 group). Pre-, intra-, and postoperative data were compared between the groups. A total of 103 women (73.6%) were in the <65 group and 37 women (26.4%) in the ≥65 group. Mean age for the entire cohort was 58 ± 9.8 years, body mass index 25.9 ± 4.8 kg/m2, and duration of follow-up was 25.9 ± 21.0 months. Women in the ≥65 group had more comorbidities, were less sexually active, and were less likely to have a midurethral sling performed during their surgery. Clinical and anatomical success rates were somewhat higher in the ≥65 group; however, these differences did not reach statistical significance (97.3% vs 85.4%, p = .069 and 89.2% vs 81.2%, p = .264, respectively). Composite outcome success was higher in the ≥65 group (89.2% vs 72.5%, p = .039). Patient satisfaction recorded using the Patient Global Impression of Improvement questionnaire was high for both groups. A multivariable logistic regression analysis for the dependent parameter of composite outcome success was performed, during which none of the parameters investigated reached statistical significance. Subgroup analysis was performed including only women who were postmenopausal. This was done to address the possible confounding effect that menopausal status may have had on our results. No differences were found between the groups with regard to clinical, anatomical, and composite outcomes. CONCLUSION: Uterine-preserving surgery is a safe and effective surgical treatment for women aged ≥65 years.

RESEARCH QUESTION: Do elective oocyte cryopreservation outcomes in women 1-13 months after SARS-CoV-2 vaccination alter compared with unvaccinated women and do different time intervals between vaccination and ovarian stimulation impact these outcomes? DESIGN: This retrospective cohort study, conducted in a university-affiliated IVF centre, included 232 elective oocyte cryopreservation cycles of vaccinated and unvaccinated patients, without previous infection with the SARS-CoV-2 virus, between December 2020 and January 2022. Two control groups - pre-pandemic (January 2019 to February 2020) and intra-pandemic (December 2020 to January 2022) unvaccinated groups - were compared with the vaccinated group, further divided into four subgroups (under 3, 3-6, 6-9 and 9-13 months). The primary outcome was the elective oocyte cryopreservation cycle outcomes - number of retrieved and number of mature oocytes. RESULTS: The vaccinated group demonstrated comparable outcomes with regards to number of retrieved and mature oocytes compared with the pre-pandemic and intra-pandemic unvaccinated groups (12.6 ± 8.0 versus 13.0 ± 8.2 and 12.5 ± 7.4 retrieved and 10.1 ± 6.9 versus 9.5 ± 6.4 and 10.1 ± 6.3 mature oocytes, respectively; not significant for both). Similar results were noted in a comparison between the intra-pandemic unvaccinated group and the four vaccinated subgroups. No correlation was found between the parameter of days from vaccination and cycle outcomes. Similarly, analysis of covariance showed no association between vaccination status and timing and number of mature oocytes. CONCLUSIONS: The SARS-CoV-2 vaccination does not alter the outcomes of elective oocyte cryopreservation procedures. This is true even in a relatively long time interval of 9 to 13 months from vaccination.

BACKGROUND: COVID-19 during pregnancy is associated with adverse outcomes for both the mother and fetus. SARS-CoV-2 vaccination has significantly reduced the risk for symptomatic disease. Several studies have reported on the safety of SARS-CoV-2 vaccination during pregnancy, with no adverse effects on the obstetrical outcomes. However, data regarding the obstetrical outcomes following a booster dose of the SARS CoV-2 vaccination during pregnancy have not yet to be published. OBJECTIVE: This study aimed to examine the association between the booster dose of the SARS CoV-2 vaccination during pregnancy and obstetrical outcomes. STUDY DESIGN: This was a retrospective cohort study of women who delivered between July and October 2021 at a large tertiary medical center. We compared women who received the booster vaccination dose during pregnancy with women who were not vaccinated and with those who only received 2 vaccination doses. Primary outcomes were the incidence of preterm labor and of small for gestational age neonates. Secondary outcomes were other maternal and neonatal complications. A secondary analysis investigating the association between the time from vaccination to delivery and the outcomes was also performed. Multivariable logistic regression models were used to adjust for potential confounders. RESULTS: There were 6507 women who met the inclusion criteria: 294 women received 3 doses of the vaccination, 2845 women received only 2 doses, and 3368 were unvaccinated. Patients receiving 3 doses of the vaccine were older and more likely to smoke than unvaccinated patients. No differences were noted among the triple-vaccinated, twice-vaccinated, and unvaccinated groups with regards to preterm birth and the incidence of small for gestational age neonates. Regarding the secondary outcomes, women in the triple-vaccinated group had higher rates of postpartum hemorrhage (9.5% vs 3.21%; P<.001) and gestational diabetes mellitus (12.2% vs 8.3%; P=.02) and were less likely to have hypertensive disorders of pregnancy (0% vs 1.4%; P=.041) than the unvaccinated group. Compared with the twice-vaccinated patients, patients with 3 doses of the vaccine were more likely to experience postpartum hemorrhage (9.5% vs 3.5%; P<.001) and were less likely to have a low umbilical artery pH (0.7% vs 6.1%; P<.001). In the sensitivity analysis comparing patients who delivered within 2 weeks of the third vaccination dose (n=53) with those who delivered at least 6 weeks after vaccination (n=96), there were no differences in the rates of small for gestational age neonates, preterm birth, postpartum hemorrhage, or cesarean delivery. CONCLUSION: Receiving the booster dose of the SARS-CoV-2 vaccination during pregnancy was not associated with adverse obstetrical outcomes when compared with unvaccinated or twice-vaccinated women. However, higher rates of postpartum hemorrhage were observed. Further studies on a larger scale are needed to confirm these findings.

BACKGROUND: COVID-19 during pregnancy is associated with adverse outcomes for mother and fetus. SARS-CoV-2 vaccination has significantly reduced the risk of symptomatic disease. Several small studies have reported the safety of SARS-CoV-2 vaccination during pregnancy, with no adverse effect on obstetric outcomes. OBJECTIVE: To examine the association between SARS-CoV-2 vaccination during pregnancy and maternal and neonatal outcomes in a large cohort study. Furthermore, to evaluate if timing of vaccination during pregnancy is related to adverse outcomes. METHODS: A retrospective cohort study of women who delivered between December 2020 and July 2021 at a large tertiary medical center. Excluded were women with multiple pregnancy, vaccination prior to pregnancy, COVID-19 infection during or before pregnancy, or unknown timing of vaccination. Primary outcomes were the incidence of preterm labor and of small for gestational age. Secondary outcomes were other maternal and neonatal complications. A secondary analysis investigating the association between time of vaccination and outcomes was also performed. Multivariable logistic regression models were used to adjust for potential confounders. RESULTS: There were 5618 women who met the inclusion criteria: 2,305 (41%) women were vaccinated and 3,313 (59%) were unvaccinated. There were no differences between vaccinated and non-vaccinated patients with respect to primary outcomes. The rate of preterm birth was 5.5% in the vaccinated group compared to 6.2% in the unvaccinated group (p = 0.31). Likewise, the rates of small for gestational age were comparable between the two groups (6.2% vs. 7.0% respectively, p = 0.2). In a secondary analysis focusing on time of vaccination and its relationship with outcomes, patients vaccinated in the second trimester (n = 964) and in the third trimester (n = 1329) were independently compared to their unvaccinated counterparts. Women who were vaccinated in the second trimester were more likely to have a preterm birth (8.1% vs. 6.2%, p < 0.001). This association persisted after adjusting for potential confounders (adjusted odds ratio 1.49, 95%CI 1.11, 2.01). CONCLUSIONS: SARS-CoV-2 vaccine appears to be safe during pregnancy with no increase in incidence of preterm labor and small for gestational age compared to unvaccinated women. However, in women vaccinated during the second trimester there may be an increase in the rate of preterm birth.

BACKGROUND: Women undergoing in-vitro fertilization (IVF) treatments are at increased risk for maternal and neonatal complications compared to women who conceive spontaneously. Though spontaneous pregnancies of young women and adolescents have an increased risk for adverse maternal and neonatal outcomes, pregnancy outcomes of this age group, following IVF treatment have been scarcely reported. The aim of this study was to report maternal and neonatal outcomes of young women who conceived following IVF compared to women in the same age group with spontaneous conception. METHODS: We performed a multicenter case-control study. The study group included women aged 17-25 years who conceived by IVF with an ongoing singleton pregnancy. For the purpose of the study, a control group matched (1:2 ratio) for maternal age at delivery and parity was constructed. Demographic, medical history, pregnancy related characteristics and maternal and neonatal outcomes were compared between groups. Finally, factors associated with spontaneous vaginal delivery were assessed for the entire cohort using a univariate and multivariate logistic regression model. RESULTS: Between 2005 and 2021, we identified 80 women aged 19-25 years who conceived by IVF. A control group of 160 women was matched to the study group by age and parity. The unmatched maternal characteristics and pregnancy associated complications were similar among the groups. However, the IVF group had a significantly higher rate of induction of labor (48.1% vs. 26.6%, p = 0.001), meconium-stained amniotic fluid (27.6% vs. 14.1%, p = 0.025), prolonged second stage of labor (26.0% vs. 7.3%, p = 0.001) and operative vaginal delivery (22.5% vs.12.5%, p = 0.048). Neonatal outcomes were for the most part comparable; nevertheless, we found a higher rate of neonates with an umbilical artery pH < 7.1 in the IVF group (9.8% vs. 0.0%, respectively; p = 0.022). A logistic regression analysis for spontaneous vaginal delivery (vs. cesarean or operative vaginal deliveries) found that spontaneous onset of labor (vs. induction of labor) (OR = 2.08; 95% CI = 1.07-4.05, p = 0.03) was positively associated with spontaneous vaginal delivery while prolonged second stage of labor (OR = 0.35; 95% CI = 0.13-0.95, p = 0.04) was negatively associated with this parameter. CONCLUSION: Young women who conceive by in-vitro fertilization are expected to reach favorable pregnancy outcomes, comparable to women who conceived spontaneously.

STUDY OBJECTIVE: To compare clinical and anatomic outcomes as well as patient satisfaction in women undergoing vaginal colposuspension using the Uphold Lite system (Boston Scientific Corporation, Marlborough, MA) and transvaginal hysterectomy with uterosacral ligament suspension (VUSLS) for the treatment of apical prolapse. DESIGN: Retrospective cohort study. SETTING: Female pelvic medicine and reconstructive surgery unit at a university-affiliated tertiary medical center. PATIENTS: Women with apical prolapse who underwent either vaginal colposuspension using the Uphold Lite system (uterine-preserving as well as after previous hysterectomy) or VUSLS from 2010 to 2019. Excluded were women with 1 month or less of follow-up. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 164 women were included in the study: 112 women underwent VUSLS, and 52 underwent colposuspension using the Uphold Lite mesh system. Age, body mass index, maximal birth weight, comorbidity rates, and pelvic organ prolapse severity were similar between the groups. The clinical cure rate was similarly high in both groups, with 91.1% in the women who underwent VUSLS and 88.5% in those in the Uphold Lite group (pâ¯=â¯.60). No differences were noted between the groups with regard to anatomic cure rate or composite outcome success rate (73.9% vs 76.0%, pâ¯=â¯.77 and 70.3% vs 74.0%, pâ¯=â¯.63, in the VUSLS and Uphold Lite groups, respectively). An advantage was noted in the VUSLS group with regard to patient satisfaction with 98.1% of the women stating that their condition was very much better (Patient Global Impression of Improvement questionnaire: A) or much better (Patient Global Impression of Improvement questionnaire: B) compared with 83.9% of the women in the Uphold Lite group (pâ¯=â¯.023). In an attempt to assess the association between different variables and the composite outcome, a multivariate analysis was performed in which increased body mass index, menopausal status, and increased preoperative genital hiatus were found to decrease composite outcome success. CONCLUSION: Vaginal colposuspension using the Uphold Lite system and VUSLS for the treatment of apical prolapse have comparable results with high clinical success rates.
