Ureteral injuries during different types of hysterecomy: A 7-year series at a single university center

Objectives: Accidental ureteral injury with gynaecologic surgery, especially hysterectomy, represents a high risk of patient morbidity. The incidence may vary from centre to centre. As the introduction of new minimally invasive surgical techniques and instruments may have affected the incidence of ureteral injury, we de novo analysed the incidence data for the last seven years. Study design: Incidence of ureteral injury was analysed stratifying the data according to the type of hysterectomy (n = 3071). The incidence rate was reported as a confidence interval (CI). Ureteral injuries were classified as direct or indirect. Results: Fifteen ureteral injuries were registered. The highest incidence was evidenced for radical hysterectomy (CI: 0.82–3.99), followed by laparoscopic radical hysterectomy (CI: 0–11.9). The incidence of direct ureteral injury was 26.6%, half of which were identified during the operative procedure. In 26.7% of the operations resulting in ureteral injury, heat-generating instruments were used. Conclusions: The incidence of ureteral injury during different types of hysterectomy was low. The majority of injuries were indirect. These were injuries which resulted from a micro-trauma, and developed due to the delayed necrosis of the ureteral wall. Laparoscopic approach to radical and simple hysterectomy didn‘t substantially raise the incidence of ureteral injury

Testosterone therapy for women with poor ovarian response undergoing IVF: a meta-analysis of randomized controlled trials

Purpose: The aim of the present systematic review and meta-analysis was to summarize evidence on the effectiveness of testosterone supplementation for poor ovarian responders (POR) on IVF outcomes. The primary outcome was live birth rate (LBR); secondary outcomes were clinical pregnancy rate (CPR), miscarriage rate (MR), total and MII oocytes, and total embryos. Methods: This meta-analysis of randomized controlled trials (RCTs) evaluates the effects of testosterone administration before/during COS compared with a control group in patients defined as POR. The primary outcome was live birth rate (LBR); secondary outcomes were clinical pregnancy rate (CPR), miscarriage rate (MR), total and MII oocytes, and total embryos. Pooled results were expressed as risk ratio (RR) or mean differences (MD) with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroup analysis. All analyses were performed by using the random-effects model. Results: Women receiving testosterone showed higher LBR (RR 2.29, 95% CI 1.31\u20134.01, p = 0.004), CPR (RR 2.32, 95% CI 1.47\u20133.64, p = 0.0003), total oocytes (MD = 1.28 [95% CI 0.83, 1.73], p < 0.00001), MII oocytes (MD = 0.96 [95% CI 0.28, 1.65], p = 0.006), and total embryos (MD = 1.17 [95% CI 0.67, 1.67], p < 0.00001) in comparison to controls, with no difference in MR (p = ns). Sensitivity and subgroup analysis did not provide statistical changes to the pooled results. Conclusions: Testosterone therapy seems promising to improve the success at IVF in POR patients. Further RCTs with rigorous methodology and inclusion criteria are still mandatory

Biomechanical Properties of the Pelvic Floor and its Relation to Pelvic Floor Disorders

Pelvic organ prolapse and stress urinary incontinence remain a clinical challenge as they have unclear pathophysiology and suboptimal treatments. These common pelvic floor disorders (PFD) are characterized by the weakening of the pelvic floor supportive tissues that are directly related to their biomechanical properties. Characterizing the biomechanical properties of the pelvic floor tissues has been the focus of recent studies and researchers are using tools that are not always well understood by clinicians. Therefore, the aim of this review is to provide an overview of the most used methods to test the passive biomechanical properties of the human pelvic floor tissues. We also summarize recent findings from studies looking into the passive properties of the pelvic floor in pelvic floor disorders using the ex vivo tensile test and emerging in vivo techniques. Together, these studies provide valuable quantitative information about the different biomechanical properties of the supportive tissues of the pelvic floor under normal and pathological conditions. Results from ex vivo tests provide valuable data that needs to be correlated to the in vivo data and the clinical manifestations of the symptoms of the PFD. As more research is conducted we will obtain an enhanced understanding of the effect of age, PFD, and treatments on the biomechanical properties of the pelvic floor. This information can contribute to better identify individuals at risk, improve clinical diagnosis, and develop new treatments to advance clinical practice. Pelvic floor disorders are characterized by the weakening of the pelvic floor tissues that is directly related to their biomechanical properties. Such properties change with age, disease, and treatments. This review provides the physician with an overview of the most used methods to investigate the passive biomechanical properties of the human pelvic floor tissues in the context of pelvic floor disorders

Endometrial scratch injury for women with one or more previous failed embryo transfers: a systematic review and meta-analysis of randomized controlled trials

Objective: To investigate endometrial scratch injury (ESI) as an intervention to improve IVF outcome in women with a history of ET failure. Design: Systematic review and meta-analysis. Setting: Not applicable. Patient(s): Infertile women undergoing IVF after one or more failed ET. Intervention(s): We included all randomized controlled trials of women undergoing IVF after one or more failed ET, where the intervention group received ESI and controls received placebo or no intervention. Pooled results were expressed as relative risk (RR) with a 95% confidence interval (95% CI). The review protocol was registered in PROSPERO before starting the data extraction (CRD42017082777). Main Outcome Measure(s): Live birth rate (LBR), clinical pregnancy rate (PR), multiple PR, miscarriage rate, ectopic pregnancy (EP) PR. Result(s): Ten studies were included (1,468 participants). The intervention group showed higher LBR (RR 1.38, 95% CI 1.05\u20131.80) and clinical PR (RR 1.34, 95% CI 1.07\u20131.67) in comparison to controls, without difference in terms of multiple PR, miscarriage rate, and EP PR. Double luteal ESI with pipelle was associated with the greatest effect on LBR (RR 1.54, 95% CI 1.10\u20132.16) and clinical PR (RR 1.30, 95% CI 1.03\u20131.65). The ESI was beneficial for patients with two or more previous ET failure, but not for women with a single previous failed ET. No effect was found in women undergoing frozen-thawed ET cycles. Conclusion(s): The ESI may improve IVF success in patients with two or more previous ET failures undergoing fresh ET. The ESI timing and technique seem to play a crucial role in determining its effect on embryo implantation

Ultrasound-guided embryo transfer: summary of the evidence and new perspectives. A systematic review and meta-analysis

Despite the purported advantages of ultrasound guidance during embryo transfer, and the large number of clinical trials published on this topic, recommendations for the use of this technique in daily clinical practice are still under debate. We designed a meta-analysis based exclusively on evidence from published randomized controlled trials, with the aim of analysing the effect of trans-abdominal ultrasound guidance during embryo transfer versus clinical touch and of transvaginal ultrasound guidance (TV-US) versus the trans-abdominal approach on IVF outcomes. On the basis of 14 randomized trials, we found a moderate quality of evidence supporting the beneficial effects of transabdominal guidance during embryo transfer compared with conventional clinical touch in clinical pregnancy and ongoing or live birth rates. No significant differences were found in miscarriage and ectopic pregnancy rate, with low or very low quality of evidence, respectively. On the basis of three randomized trials, we found the quality of evidence supporting the equivalence of transvaginal versus transabdominal approach in clinical pregnancy and ongoing or live birth rates to be low. Finally, larger randomized controlled trials are necessary to explore the possible benefits of TV-US, three-dimensional ultrasound imaging modality, and uterine length measurement before transfer

Patients' satisfaction and safety of bulk injection therapy Urolastic for treatment of stress urinary incontinence: A cross-sectional study

Aims: Primary outcome was to evaluate patients' satisfaction after being treated with bulk injection therapy polydimethylsiloxane Urolastic (PDMS-U) for stress urinary incontinence (SUI). Secondary outcomes were: subjective cure, objective cure, severity of SUI symptoms, complications, reintervention rate, and disease-specific quality of life. Furthermore, to determine if outcomes worsened during time-after-treatment (time-frames: 0-12, 13-24, and ≥25 months). Methods: In a cross-sectional design, patients treated with PDMS-U were recruited for hospital revisit. The primary outcome, patients' satisfaction, was assessed by the surgical satisfaction questionnaire. Subjective cure, objective cure, and severity of symptoms were assessed by the patients global impression of improvement, standardized cough stress test, and Sandvik severity scale, respectively. Medical charts and face-to-face interviews were used to determine complications and reinterventions. Results: About 110 patients participated, 87 revisited the hospital. Median follow-up was 25 months (interquartile range: 14;35 months). Patients' satisfaction rate was 51%. Subjective and objective cure were respectively 46% and 47%. Most prevalent complications were: urinary retention (22%), pain (15%), and dyspareunia (15%). Exposure and erosion occurred in 7% and 5%, respectively. Reintervention rate of reinjection and excision of bulk material was 6% and 18.0%, respectively. Objective cure significantly worsened during time-after-treatment (P = <.05). Conclusions: About half of the patients being treated with PDMS-U were satisfied and subjectively cured 2 years after treatment, although the majority still experienced symptoms of SUI. Most complications were mild and transient, however, in 18% excision of bulk material was indicated for severe or persistent complications such as pain, exposure, or erosion
