What is already done by different societies in reduction of maternal mortality? Are they successful at all?

Maternal mortality represents a major issue for every health system, especially in developed countries that aim on creating protocols to retain a declining pattern. With the appropriate medical supplies and training, some of these countries have made a remarkable progress in preventing maternal morbidity and mortality. On the contrary, developing countries have still made little or even no progress. Identifying determinants and designing strategies is of great importance in order to overcome such difficulties. The aim of this study is to identify the main causes of maternal mortality in the different societies.

Presence of amniotic fluid sludge and pregnancy outcomes: A systematic review.

INTRODUCTION: Several studies acknowledge that the presence of amniotic fluid sludge (AFS) is an independent predictive factor for preterm birth. In the present systematic review, we summarize research that focuses on the comparison of pregnancy outcomes among women with and without AFS. MATERIAL AND METHODS: Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar databases were systematically searched from inception. Both observational and randomized controlled studies were considered eligible provided that they reported data on pregnancy outcomes among women with and without AFS. Outcomes were not meta-analyzed because of the high heterogeneity in terms of selected population and outcome reporting. RESULTS: Seventeen studies of 2432 women were included in this review. Six studies evaluated women at high risk for preterm birth. Pregnancies complicated by AFS had a lower gestational age at delivery and increased incidence of preterm delivery at <37 weeks. Neonatal death rates and admission to the Neonatal Intensive Care Unit were also increased. Evidence in low-risk women, those with signs of preterm labor, in those carrying twins, and in women with cervical cerclage or Arabin pessary was extremely limited. CONCLUSIONS: Women with AFS seem to deliver at an earlier gestational age, and preterm birth rates are also increased. Limited data seem to point to neonatal morbidity and mortality being increased. However, the presence of a direct association should not be assumed because the evidence is not adjusted for the presence of confounders.

Progestogens for the prevention of preterm birth and risk of developing gestational diabetes mellitus: a meta-analysis.

BACKGROUND: Several articles have implied that progestogen supplementation during pregnancy to reduce the risk of preterm birth may increase the risk for developing gestational diabetes mellitus. OBJECTIVE: The purpose of the present meta-analysis was to accumulate existing evidence concerning this correlation. DATA SOURCES: We searched Medline (1966-2019), Scopus (2004-2019), Clinicaltrials.gov (2008-2019), EMBASE (1980-2019), Cochrane Central Register of Controlled Trials CENTRAL (1999-2019), and Google Scholar (2004-2019) databases. STUDY ELIGIBILITY CRITERIA: Randomized trials and observational studies were considered eligible for inclusion in the present meta-analysis. To minimize the possibility of article losses, we avoided language, country, and date restrictions. STUDY APPRAISAL AND SYNTHESIS METHODS: The methodological quality of included studies was evaluated with the Cochrane risk of bias and the Risk Of Bias In Non-Randomized Studies of Interventions (ROBINS-I) tool. Meta-analysis was performed with the RevMan 5.3 and secondary analysis with the Open Meta-Analyst software. Trial sequential analysis was conducted with the trial sequential analysis program. RESULTS: Overall, 11 studies were included in the present meta-analysis that recruited 8085 women. The meta-analysis revealed that women who received 17-alpha hydroxyprogesterone caproate had increased the risk of developing gestational diabetes mellitus (risk ratio, 1.73, 95% confidence interval, 1.32-2.28), whereas women who received vaginal progesterone had a decreased risk, although the effect did not reach statistical significance because of the unstable estimate of confidence intervals (risk ratio, 0.82, 95% confidence interval, 0.50-1.12). Meta-regression analysis indicated that neither the methodological rationale for investigating the prevalence of gestational diabetes mellitus (incidence investigated as primary or secondary outcome) (coefficient of covariance, -0.36, 95% confidence interval, -0.85 to 0.13, P = .154) nor the type of investigated study (randomized controlled trial/observational) (coefficient of covariance -0.361, 95% confidence interval, -1.049 to 0.327, P = .304) significantly altered the results of the primary analysis. Trial sequential analysis suggested that the meta-analysis concerning the correlation of 17-alpha hydroxyprogesterone caproate was of adequate power to reach firm conclusions, whereas this was not confirmed in the case of vaginal progesterone. CONCLUSION: The results of the present meta-analysis clearly indicate that women who receive supplemental 17-alpha hydroxyprogesterone caproate for the prevention of preterm birth have an increased risk of developing gestational diabetes mellitus. On the other hand, evidence concerning women treated with vaginal progesterone remains inconclusive.

Prevention of spontaneous preterm birth.

BACKGROUND: It is estimated that globally, approximately 13 million preterm infants are born annually and a much higher number of pregnancies are characterized by threatening preterm birth. FINDINGS: A proportional inverse correlation between gestational age at delivery and neonatal mortality has been observed which is more prevalent in countries without high standard neonatal care. The socioeconomic burden of preterm birth is enormous, as preterm neonates are particularly prone to severe morbidity that may expand up to adulthood. Several strategies have been proposed for the prevention of preterm birth which can be sub-stratified as primary (when these apply to the general population), secondary (when they target women at risk), and tertiary (optimizing neonatal outcomes when preterm birth cannot any longer be prevented). The aim of this review is to summarize the most important strategies.

Safety and efficacy of the cervical pessary combined with vaginal progesterone for the prevention of spontaneous preterm birth.

INTRODUCTION: The aim of this study was to evaluate the safety and efficacy of the combined treatment of cervical pessary and endovaginal progesterone for the prevention of spontaneous preterm birth (SPB) in women with a short cervical length (CL) between 20 and 24 weeks of gestation. MATERIALS AND METHODS: This is a prospective study of women with a singleton pregnancy and a sonographically detected mid-trimester CL ≤25 mm. The primary outcome measure was spontaneous delivery before 34 weeks (238 days) of gestation. RESULTS: The study sample consisted of 90 women with a mean CL of 14.2 mm (SD=6.5 mm). Of the women, 34.4% had at least one risk factor for SPB; 7.8% delivered preterm before 34 weeks of gestation, and 25.6%, before 37 weeks. Neonatal death occurred in two (2.2%) cases due to respiratory distress syndrome. Lower body mass index values, history of preterm delivery and number of second trimester miscarriages were independently associated with delivery before 34 weeks. CONCLUSION: The combination of vaginal progesterone and cervical pessary for the prevention of SPB in women with a short cervix is safe and well tolerated. This therapy was associated with pregnancy prolongation, reduced prematurity rate and a low rate of perinatal complications.

Subserosal uterine injection of blue dye for the identification of the sentinel node in patients with endometrial cancer: a feasibility study.

OBJECTIVE: To define the detection rate, sensitivity, and negative predictive value (NPV) of the sentinel node technique in patients with endometrial cancer. METHODS: Patients with endometrial cancer after informed consent underwent subserosal injection of blue dye during hysterectomy in a tertiary gynae/oncology department between 2010 and 2014. The procedure was performed in all cases by the same team including two gynae/oncologist consultants and one trainee. All relevant perioperative clinicopathological characteristics of the population were recorded prospectively. The identified sentinel nodes were removed separately and a completion bilateral pelvic lymphadenectomy followed in all cases. Simple statistics were used to calculate the sensitivity and NPV of the method on per patient basis. RESULTS: Fifty-four patients were included in this study. At least one sentinel node was mapped in 46 patients yielding a detection rate of 85.2%. Bilateral detection of sentinel nodes was accomplished in only 31 patients (57.4%). The mean number of sentinel nodes was 2.6 per patient and the commonest site of identification was the external iliac artery and vein area (66%). Six patients (11%) had a positive lymph node, and in five of them, this was the sentinel one yielding a sensitivity of 83.3% and an NPV of 97.5%. The overall detection rate improved significantly after the first 15 cases; however, this was not the case for the bilateral detection rate. CONCLUSION: Our study is in accordance with previous studies of sentinel node in endometrial cancer and further demonstrates and enhances the confidence in the technique. In the current era of an ongoing debate on whether a systematic lymphadenectomy in patients with endometrial cancer is still necessary, we believe that the sentinel node is an acceptable alternative and should be applied routinely in tertiary centres following a strict algorithm.

Expression of vascular endothelial factor-A, gelatinases (MMP-2, MMP-9) and TIMP-1 in uterine leiomyomas.

BACKGROUND: Leiomyomas growth involves cellular hypertrophy, modulation of mitotic activity and upregulation of extracellular matrix (ECM). Vascular factors and matrix metalloproteinases (MMPs) play a coordinated role during neoplasia and tissue remodeling. The present study investigates the role of angiogenic factor vascular endothelial growth factor (VEGF)-A with the activity of main gelatinases, MMP-2/MMP-9 and their tissue inhibitor TIMP-1 in patients with leiomyomas. METHODS: Peripheral blood of 46 women with uterine leiomyomas was obtained prior hysterectomy to assess VEGF-A, MMP-2, -9, TIMP-1 levels by enzyme-linked immunosorbent assay compared to 39 healthy controls. Protein expression levels of VEGF-A, MMP-2 and MMP-9 were evaluated by western immunoblotting and immunohistochemistry in leiomyomas tissue specimens after hysterectomy. Furthermore, the activity of gelatinases in leiomyoma tissue extracts and control myometrium was evaluated by semi-quantitative zymography. RESULTS: Circulating levels of VEGF-A, MMP-2 and TIMP-1 were significantly elevated in leiomyoma patients compared to controls (p<0.001, p=0.004, p=0.003, respectively). A positive correlation was found between VEGF-A and MMP-2 (p=0.021) as well as MMP-9 (p=0.001) peripheral levels in the patient's group. Furthermore, increased VEGF-A protein levels were detected in leiomyoma tissue compared to control myometrium, followed by increased localization of both VEGF-A and MMP-2 in the ECM embedding bundles of smooth muscle cells of leiomyomas. The activity of MMP-2 was significantly higher in leiomyomas than normal myometrium in all investigated tissues. CONCLUSIONS: This study demonstrates a possible coordinated role of VEGF-A and MMP-2 during uterine leiomyomas growth and angiogenesis with potential prognostic significance.

Risk for fetal loss and prematurity after 12,413 second trimester amniocenteses in a single center.

OBJECTIVES: The purpose of this retrospective controlled study is to estimate the risk for fetal loss and preterm delivery attributed to second trimester amniocentesis from a single tertiary center. METHODS: The study group consists of 12,413 singleton pregnancies with consecutive amniocenteses, performed in a single tertiary center during a 15-year period (1996-2010) with known pregnancy outcome. The control group consisted of 6993 pregnancies with negative second trimester screening for aneuploidies during the same period who did not have any invasive test. The two groups were compared in terms of fetal loss rate up to 24 weeks and premature deliveries. RESULTS: Total fetal loss up to 24 weeks in the study group, excluding terminations of pregnancy, was estimated at 1.25% (1.05%-1.45%, confidence interval [CI]: 95%). In the control group the loss rate was 0.65% giving a procedure related fetal loss rate of 0.6% which was not found to be a statistically significant difference. Delivery before the 28th, 32nd, 34th, and 37th week in the study group was reported in 0.2%, 0.8%, 1.2% and 8.1% respectively, and it was not statistically different from controls. CONCLUSION: The present study has shown that the risk of miscarriage that can be attributed to amniocentesis in our institution is 0.6%, and this is not statistically significant when compared with cases without any invasive procedure during pregnancy. Similarly, the risk for preterm labor was not statistically significant when compared with controls.

Seven years of objective and subjective outcomes of transobturator (TVT-O) vaginal tape: why do tapes fail?

INTRODUCTION AND HYPOTHESIS: This study reports long-term outcomes of the transvaginal tension-free vaginal tape-obturator (TVT-O) procedure for treating stress urinary incontinence (SUI), including possible risk factors for failure. METHODS: This was a retrospective study of women who underwent TVT-O with or without concomitant prolapse surgery. Procedures were performed at a tertiary referral urogynecology unit. Participants presented with SUI and had urodynamic stress incontinence (USI). Women with a history of previous anti-incontinence procedures, radical pelvic surgery, and detrusor overactivity (DO) were excluded. Objective cure was defined as absence of urine leakage during a cough stress test (CST). Subjective outcome was based on the International Consultation on Incontinence Questionnaire for Evaluating Female Lower Urinary Tract Symptoms (ICIQ-FLUTS). Quality of life was assessed using the King's Health Questionnaire (KHQ). Univariate and multivariate analyses were used to identify risk factors for subjective failure. RESULTS: One hundred twenty-four consecutive women were assessed, with a median follow-up of 90.3 (range 80-103) months. Overall objective and subjective cure rates were 81.5 % (101/124) and 83.5 % (103/124), respectively. A significant improvement was observed in all KHQ domains. Concomitant vaginal hysterectomy [odds ratio (OR) = 2.98, 95 % confidence interval (CI) 1.10-8.05, p = 0.03] and increasing point C (OR = 1.17, 95 % CI 1.05-1.30, p = 0.006] were associated with a higher risk for subjective failure. De novo urgency rate was 7 %. CONCLUSIONS: The TVT-O procedure provides high objective and subjective long-term efficacy, a clinically meaningful improvement in patient quality of life, and an excellent safety profile. Concomitant vaginal hysterectomy and apical compartment prolapse were associated with a higher risk for objective and subjective failure.

Does the presence of thyroid antibodies affect the course and outcome of pregnancy in type 1 diabetic women?

OBJECTIVE: The aim of the study was to evaluate the significance of the presence of thyroid peroxidase autoantibodies (anti-TPO Abs) in type 1 diabetes mellitus (DM1) pregnant women relative to the course of pregnancy and, especially, with regard to metabolic control, thyroid function, maternal complications and neonatal outcome. METHODS: In a prospective observational study of 91 DM1 women with singleton pregnancies, anti-TPO, anti-thyroglobulin, thyroid-stimulating hormone (TSH), and free thyroxine index (T4/thyroid binding capacity) were measured in each trimester. At each visit, HbA1c, body mass index, and units of insulin per kilogram were recorded, as were complications and pregnancy outcome. RESULTS: Twenty-one (27%) of the 78 women who met the inclusion criteria presented with positive anti-TPO Abs. There were no differences regarding glycemic control (HbA1c) or insulin dose. First-trimester TSH levels were significantly higher in the anti-TPO-positive group than in the anti-TPO-negative group. Finally, no differences were observed regarding diabetic or obstetric complications and neonatal outcome. CONCLUSION: One fourth of DM1 pregnant women presented with positive anti-TPO Abs. However, the presence of anti-TPO Abs does not seem to be related with worse metabolic control or adverse pregnancy outcome. Further investigation is needed; meanwhile, the effort for early treatment of thyroid dysfunction and strict metabolic control in all DM1 women should be continued.

Gynecologic oncology patients in the surgical high dependency unit: an analysis of indications.

PURPOSE: The establishment of high dependency units (HDUs) has been an undoubted advance in the management of patients undergoing major oncological procedures. The aim of this study was to examine the impact of various preoperative and perioperative patients' characteristics on the prolonged HDU stay. METHODS: We conducted a retrospective study including all gynecologic oncology patients who underwent surgical management and were admitted postoperatively to our hospitals' HDU from 2006 to 2010. RESULTS: A total of 1,014 patients were transferred to the HDU and divided into two groups according to the length of HDU stay. Group A consisted of 840 (82.8 %) patients who stayed in the HDU for ≤24 h and Group B included 174 (17.2 %) patients who remained in the HDU under close observation for >24 h. Older age was the only preoperative characteristic that remained significantly associated with HDU prolonged stay. In addition, three intraoperative factors such as use of invasive hemodynamic monitoring, bowel resection and estimated blood loss were proved to be independently associated with prolonged HDU stay. CONCLUSION: Certain characteristics could identify those patients who are more likely to benefit most from HDU admission.

The ethics and practice of perinatal care at the limit of viability: FIGO recommendations.

An arbitrary gestational age limit of viability cannot be set, and in clinical practice the focus should be on a periviability interval-the so-called "gray zone" of prognostic uncertainty. For cases within this interval, the most appropriate decision-making process remains debatable and periviability has emerged as one of the greatest challenges in bioethics. Universally recognized ethical principles may be interpreted differently due to socioeconomic, cultural, and religious aspects. In the case of periviability, there is considerable uncertainty over whether interventions result in a greater balance of clinical good over harm. Furthermore, the fetus or neonate is unable to exercise autonomy and the physicians and parents will act as patient surrogates. When parents and physicians disagree about the infant's best interest, a dialogue without paternalistic attitudes is essential, whereby physicians should only offer, but not recommend, perinatal interventions. Parental choice, based on thorough information, should be respected within the limits of what is medically feasible and appropriate. When disagreements between parents and physicians occur, how is consensus to be achieved? Professional guidelines can be helpful as a framework and starting point for discussion. In reality, however, guidelines only rarely draw categorical lines and in many cases remain vague and ambiguously worded. Local ethics committees can provide counseling and function as moderators during discussions, but ethics committees do not have decision precedence. Counseling assumes the most significant role in periviability discussions, taking into consideration the particular fetal and maternal characteristics, as well as parental values. Several caveats should be observed relative to counseling: message fragmentation or inconsistence should be minimized, prognosis should preferably be presented in a positive framing, and overreliance on statistics should be avoided. It is recommended that decisions regarding neonatal resuscitation in the periviability interval be made before birth and not conditional on the newborn's appearance at birth. Regardless of decision, it is important to assure pre- and postnatal coherence. The present article describes how individual physicians, centers, and countries differ in the approach to the decision to initiate or forgo intensive care in the periviability interval. It is impossible to provide a global consensus view and there can be no unifying ethical, moral, or practical strategy. Nevertheless, ethically justified, quality care comprises early involvement of the obstetric and neonatal team to enable a coherent, comprehensible, nonpaternalistic, and balanced plan of care. Ultimately, physicians will need to adjust the expectations to the local standards, local outcome data, and local neonatal support availability.

Improved survival trends in platinum-resistant patients with advanced ovarian, fallopian or peritoneal cancer treated with first-line paclitaxel/platinum chemotherapy: the impact of novel agents.

OBJECTIVE: The prognosis for patients with platinum-resistant advanced ovarian cancer remains poor. The impact of approved agents on survival has not been clarified during the last decade. We studied survival trends during the last 15 years in platinum-resistant patients treated with cytoreductive surgery followed by paclitaxel/platinum chemotherapy. METHODS: Patients with epithelial ovarian, fallopian or peritoneal cancer, stages III/IV and platinum-resistant disease after first-line chemotherapy with paclitaxel/platinum were included. They were grouped according to the period of chemotherapy: group A 31/3/1995-31/12/2001 (n = 56) and Group B 1/1/2002-24/12/2008 (n = 57). In order to compensate for the difference in follow-up between the 2 groups, we performed minimum follow-up (MFU) analyses by considering as cases only women who had an event within 3 years of follow-up. Patients with no events for up to 3 years were censored at that time. RESULTS: MFU analyses showed that median overall survival (OS) was significantly longer in group B: 12.3 vs. 17.5 months (p = 0.012). This was due to a doubling of the median OS after relapse: 5.7 vs. 10.9 months (p = 0.0180). Multivariate Cox regression indicated group and histology as factors statistically significantly associated with OS. Following relapse, patients in group B were predominantly treated with liposomal doxorubicin and gemcitabine, and patients in group A were treated with platinum compounds, docetaxel and oral etoposide (p < 0.001). CONCLUSIONS: The introduction of novel agents without cross-resistance to platinum or taxanes has improved the prognosis of platinum-resistant patients.

MMP-2 -1306C>T polymorphism in breast cancer: a case-control study in a South European population.

This case control study aims to investigate the role of MMP-2 -1306C>T polymorphism as a potential risk factor and possible prognostic marker for breast cancer in a South European population. 113 consecutive incident cases of histologically confirmed ductal breast cancer and 124 healthy controls were recruited. MMP-2 -1306C>T polymorphism was genotyped; multivariate logistic regression as well as Cox regression analysis were performed. MMP-2 -1306C>T status was not associated with breast cancer risk either at the total sample or at the subanalyses on premenopausal and postmenopausal women. At the survival analysis, a trend towards a favorable association between MMP-2 -1306C>T allele and disease-free survival as well as overall survival was observed. Regarding subanalyses on ER-negative and ER-positive cases, the favorable association implicating MMP-2 -1306C>T allele was particularly evident among ER-positive cases; no significant associations emerged among ER-negative cases. MMP-2 -1306C>T polymorphism does not seem to be a risk factor for breast cancer in South European population; however, a trend towards a favorable association with survival has been observed.

Characterization of ovarian tumors and staging ovarian cancer with 3-dimensional power Doppler angiography: correlation with pathologic findings.

OBJECTIVE: The aims of this study were to evaluate ovarian tumors with 3-dimensional power Doppler angiography (3-DPDA), to determine its correlation with histology findings, and to explore its role in staging patients with ovarian cancer. METHODS: Three hundred eighteen women with an unknown unilateral pelvic mass were referred for preoperative evaluation by 3-DPDA angiography. Patients' ages ranged from 18 to 72 years (47.4 ± 13.8 years). Sonographic criteria used for the characterization of ovarian tumors were based on a system that included morphological characteristics, histological evaluation, and Power Doppler imaging. RESULTS: Two hundred twenty-five tumors were histopathologically diagnosed as benign and 93 as malignant. Sensitivity and specificity of the 3-DPDA of ovarian masses reached 93.5% and 92.9%, respectively, whereas positive predictive value was 84.5% and negative predictive value was 97.2%. CONCLUSIONS: Three-dimensional power Doppler sonography is an effective imaging technique for discriminating ovarian neoplasms and classifying them according to histopathology.

RASSF1A in maternal plasma as a molecular marker of preeclampsia.

OBJECTIVES: This study aimed to quantitate cell free (cf) and cell free fetal (cff) DNA in maternal plasma by determining RASSF1A levels before and after enzyme digestion in women who subsequently developed preeclampsia (PE) and compare them with uncomplicated pregnancies. METHODS: Twenty-four samples from pregnant women who developed PE and 48 samples from women with uncomplicated pregnancies were analysed. Blood samples were obtained at 11-13 weeks. cfDNA was determined by quantifying RASSF1A using qRT-PCR. A second qRT-PCR was performed following methylation-sensitive enzyme digestion by BstUI, to quantitate hypermethylated RASSF1A sequences of fetal origin. ACTB gene was used as control to confirm complete enzyme digestion. RESULTS: cfDNA and cffDNA levels were significantly increased in women who developed PE as compared with uncomplicated pregnancies (median cfDNA: 9402 vs 2698, median cffDNA: 934.5 vs 62, respectively). Following operating characteristic curve analysis, cut-off values of 7486 Εq/mL for cfDNA and 512 Εq/mL for cffDNA were chosen, which provided a sensitivity of 75% and 100% and specificity of 98% and 100%, respectively, to identify women at risk for PE. CONCLUSIONS: The study demonstrates potential use of cfDNA and cffDNA in maternal plasma as markers for the early prediction of women at risk for PE.

The vaginally assisted laparoscopic sacrocolpopexy: a pilot study.

INTRODUCTION AND HYPOTHESIS: We assessed the efficacy and safety of an operative technique, the vaginally assisted laparoscopic sacrocolpopexy (VALS), for the treatment of women with severe uterovaginal prolapse (UVP). METHODS: A prospective pilot study of women with severe UVP, who underwent VALS, was carried out. Preoperatively, POP was assessed using the International Continence Society Pelvic Organ Prolapse Quantification (ICS POP-Q) system and symptoms were evaluated using the International Consultation on Incontinence Modular Questionnaire-Vaginal Symptoms (ICIQ-VS). VALS is a combined minimally invasive surgical approach where a vaginal hysterectomy is initially performed, followed by a transvaginal placement of a synthetic mesh which is suspended laparoscopically on the sacral promontory. Postoperative assessment at 12 months was identical to the preoperative assessment with the addition of the Patient Global Impression of Improvement (PGI-I) for urogenital prolapse. Perioperative and postoperative complications were recorded. RESULTS: Twenty-seven women with a mean age of 57.2 (range, 47-73) were included. Twenty women (74.1%) had stage 3 and 7 (25.9%) had stage 4 POP with a median point C = +5 (range, +2 to +8). VALS was successfully performed in all patients. All patients completed their follow-up assessment at 12 months. All POP-Q points showed statistically significant improvement apart from TVL, which remained unchanged. ICIQ-VS scores showed a statistically significant improvement of the vaginal symptoms and the total quality of life. The sexual matters score showed a tendency towards improvement, although it did not reach statistical significance. CONCLUSIONS: Vaginally assisted laparoscopic sacrocolpopexy appears to be a valid and safe minimally invasive option when treating women presenting with severe UVP, with encouraging short-term anatomical and functional outcomes.

Midurethral slings for women with urodynamic mixed incontinence: what to expect?

INTRODUCTION AND HYPOTHESIS: We assessed the efficacy of midurethral slings (MUS) in women with urodynamically proven mixed incontinence (UMI). METHODS: A prospective study was carried out in women with UMI in whom conservative treatment failed and who underwent MUS. Pre- and postoperative assessment included: completion of the validated ICIQ-FLUTS questionnaire, POP-Q examination and urodynamics (UDS). The primary outcome was the assessment of symptoms at 12 months. Secondary outcomes included assessment of postoperative UDS findings and evaluation of differences in symptoms and UDS diagnosis between the TVT and TVT-O groups. RESULTS: Eighty-five women were included; 44 (49.2%) underwent TVT and 41 (51.8%) underwent TVT-O. Concomitant prolapse surgery was performed in 65 out of 85 patients (76.5%). At 12 months' follow-up there was a statistically significant reduction in stress urinary incontinence (p < 0.001), urge urinary incontinence (p < 0.001), urgency (p = 0.021) and frequency (p = 0.014). Depending on the symptom 10.6% to 24.7% of women reported deterioration of symptoms. UDS at 12 months revealed the absence of urodynamic stress incontinence (USI) in 82.4% of patients and no evidence of detrusor overactivity (DO) in 35.3%. No differences in symptoms were found between the TVT and TVT-O group, but the absence of DO was more common in the TVT group (48.5% vs 22.7%, p = 0.014). CONCLUSIONS: Placement of MUS alleviates incontinence and overactive bladder symptoms in patients with UMI. TVT causes similar subjective improvement to TVT-O, but resulted in higher resolution of DO. Our study provides data that could be helpful in informing patients preoperatively of the potential impact that the MUS may have on each individual symptom separately, including the likelihood of symptom deterioration.
