A Monocentric Randomized Controlled Clinical Trial to Compare Single- and Double-Lumen Needles in Oocyte Retrieval Procedure in Assisted Reproductive Technologies.

The purpose was to determine any difference in outcomes, primarily in terms of number of retrieved oocytes per procedure, between two different needles used for oocytes retrieval procedure in Assisted Reproductive Technologies: the single-lumen needle (SLN) versus the double-lumen needle (DLN) with follicle flushing after aspiration. This randomized controlled trial included oocyte retrieval (OR) cycles for IVF and ICSI performed in 18 to 42-year-old women between March 2019 and January 2021 at a tertiary-care Fertility Center. A total of 200 ORs were randomized, 100 in each group. The mean number of retrieved oocytes was not different between groups (10.2 ± 6.5 for DLNs vs. 10.7 ± 7.0 for SLNs, p = 0.810). No significant differences were observed also in terms of number of retrieved oocytes/punctured follicles (83.0% ± 27.0% vs. 81.0% ± 22.0%, p = 0.916), number of retrieved oocytes/follicles at trigger (78.0% ± 29.0% vs. 78.0% ± 27.0%, p = 0.881), number of mature oocytes (7.6 ± 5.3 vs. 8.0 ± 5.1, p = 0.519), and pregnancy rate (27% vs. 23%, p = 0.514). However, the time required to retrieve each oocyte was longer using the DLN (1.5 ± 1.3 vs. 1.1 ± 0.9 minutes, p = 0.002). The present study confirmed the new perspectives on the sole use of SLNs in terms of saving time, without affecting the number of retrieved oocytes.

Ovarian Hyperstimulation: Diagnosis, Prevention, and Management.

Ovarian hyperstimulation syndrome (OHSS) is a severe complication of controlled ovarian stimulation (COS). Pathogenesis of the disease is based on massive transudation of protein-rich fluid from the vascular compartment into the peritoneal, pleural and pericardial spaces, with a variable picture of clinical manifestations depending on its severity. Nowadays OHSS can easily be avoided by several prevention methods, ranging from identification of high-risk patients, choice of a correct protocol stimulation, trigger with gonadotropin-releasing hormone (GnRH) agonists or, finally, the freeze-all strategy. When OHSS occurs, it can usually be managed as outpatient care. Only if severe/critical cases are diagnosed hospitalization is necessary for appropriate rehydration, monitoring of fluid balance and eventual drainage of ascitic fluid. One of the most dangerous complications of OHSS is venous thromboembolism (VTE). Thromboprophylaxis has shown to be cost effective and widely used, while there are controversies regarding the usage of low dose aspirin (LDA) as a preventive measure.

Urodynamics are necessary for patients with asymptomatic pelvic organ prolapse.

AIM: To evaluate the role of pre-operative urodynamics in women with pelvic organ prolapse, who are asymptomatic for urinary symptoms. Correlate urodynamics findings with King's Health Questionnaire (KHQ) responses. MATERIALS AND METHODS: Retrospective review of prospectively collected data on routine pre-operative urodynamics investigations in women with urogenital prolapse requiring surgery. Patients who were reported to be asymptomatic of urinary symptoms at the urogynaecological clinical consultation, were included for analysis. KHQ and urodynamics data were reviewed. RESULTS: A 800 records of women having routine pre-operative urodynamics were collected over a 10-year period, were reviewed. 98/800 (12%) were aymptomatic of urinary symptoms and underwent urodynamics. 82/98 (84%) completed the KHQ. 48/98 (49%) had normal urodynamics. 30/98 (31%) had detrusor overactivity (DO). 17/98 (17%) showed occult urodynamic stress incontinence (USI). 3/98 (3%) both DO and USI. 28/98 (29%) had peak flow rate less than 15 mL/s. Forty-five percent of women reporting nocturia had DO. Nine percent had over 100 mL residuals after the free flow study. Routine pre-operative urodynamics changed management in 25/98 (25%) of asymptomatic prolapse patients. TVT was performed in 12 patients. One patient who declined TVT for moderate occult USI, developed new-onset stress urinary incontinence post-operatively. CONCLUSION: This data show, that an accurate pre-surgical evaluation of patients with prolapse is incomplete without a structured validated questionnaire and urodynamics, due to the high proportion of abnormal KHQ and UDS findings in presumably "asymptomatic" patients.

ICS teaching module: Ambulatory urodynamic monitoring.

AIM: To present the ICS Teaching Module on ambulatory urodynamics monitoring (AUM). METHODS: This teaching module has been developed by the ICS Urodynamics Committee to assist ICS members in their routine clinical practice. A detailed literature search on studies published on the clinical role of AUM as well as expert opinions have been considered. A slide set on AUM has been developed, approved by all members of the ICS Urodynamics Committee and is available to the ICS membership on the ICS website. The final approved teaching module has been presented at the ICS Annual Scientific Meeting in Brazil 2014. RESULTS: The scientific evidence on the clinical role of AUM in patients with lower urinary tract symptoms is summarized. The catheters and recording systems used, the patient preparation for the test, the technique, the instructions to the patient, the analysis, interpretation, and quality control assessment of AUM trace as well as the contraindications for AUM are described. CONCLUSIONS: The clinical role of AUM is still controversial. The scientific evidence on the usefulness of AUM is still limited but the ICS Urodynamics Committee recommends its use as a second line diagnostic tool when office laboratory urodynamics have failed to achieve a diagnosis. AUM has been showed to be more sensitive than laboratory urodynamics in diagnosing detrusor overactivity but the level of evidence for this measurement is not high. This manuscript summarizes the evidence and provides practice recommendations on AUM for teaching purposes in the framework of an ICS teaching module. Neurourol.

Acute post-partum urinary retention: analysis of risk factors, a case-control study.

PURPOSE: The aim of this retrospective case-control study was to assess clinical factors that can predict the occurrence of post-partum urinary retention (PPUR) and evaluate their influence as independent risk factors. METHODS: Between January 2008 and December 2010, 11,108 vaginal deliveries were performed. 105 women who suffered from PPUR were detected by retrospective data analysis. PPUR was defined as the inability to have spontaneous micturition within 6 h after vaginal delivery. RESULTS: Data analysis detected six risk factors for PPUR on-set: primiparity, vacuum-assisted delivery, uterine fundal pressure during the second stage of labor (Kristeller's maneuver), a longer second stage of labor, medio-lateral episiotomy, initial higher dose of epidural analgesia. Nevertheless, logistic regression showed that only vacuum-assisted delivery and Kristeller's maneuver were significant independent risk factors (P = 0.001 and 0.009, respectively). CONCLUSIONS: Our study identified these risk factors as the cause of mechanical and neurological damage, which can lead to post-partum urinary retention. By early diagnosis, a prompt and appropriate management of PPUR can be established in order to assure a rapid return to normal bladder function after vaginal delivery.

Ultrasound mass screening for congenital anomalies of the kidney and urinary tract.

BACKGROUND: There is a high incidence of congenital anomalies of the kidneys and urinary tract (CAKUT). Early diagnosis of these defects may allow the best medical and/or surgical treatment to be implemented as rapidly as possible, preventing or at least slowing down an evolution toward chronic kidney disease. METHODS: Ultrasound mass screening for kidney and urinary tract abnormalities in infants at 2 months of age was carried out in Salento, Italy. The centers involved in the study examined a total of 17,783 infants between January 1992 and December 2010. RESULTS: A total of 171 CAKUT were identified in the course of the mass screening. The frequency of CAKUT was 0.96%. Vesicoureteral reflux (n = 39) was the most frequent renal abnormality found, followed by ureteropelvic junction obstruction (n = 33), ectopic kidney (n = 26), and renal dysplasia (n = 19). In addition, nephrogenic rests (n = 2), as well as several extra-renal pathologies, including abdominal neuroblastoma (n = 3), were diagnosed incidentally. CONCLUSION: Ultrasound has been effective for early detection of renal and urinary tract anomalies. In addition, this screening has proved to be very useful for the early identification and management of both renal and extra-renal precancerous as well as cancerous lesions. However, most patients requiring surgery in this study (0.24%) would probably have been symptomatic and come to medical attention without routine screening. On the basis of our results screening is not justified.
