Background: The NuvaRing®, a hormonal vaginal contraceptive device, has gained widespread usage due to its favourable efficacy and safety profiles. Exceedingly rare instances of unintended misplacement in the bladder have been reported. This study presents a review of the literature and the first video report illustrating the extraction of an intravesical NuvaRing®, discussing diagnostic and therapeutic approaches.

Objective: To illustrate an effective method for intravesical NuvaRing® retrieval and raise awareness about this unusual complication.

Materials and methods: A 27-year-old patient with low urinary tract symptoms related to NuvaRing® misplacement underwent diagnostic procedures, including ultrasound and diagnostic cystoscopy. A cystoscopic extraction under general anaesthesia was performed.

Main outcome measures: The effectiveness of pelvic ultrasound for diagnosing an intravesical foreign body, successful cystoscopic removal of NuvaRing® from the bladder, and symptom resolution were assessed.

Results: The intravesical NuvaRing® was identified through pelvic ultrasound. During cystoscopy, the ring was detected inside the bladder. Multiple attempts with cystoscopic alligator graspers were made; the NuvaRing® was eventually extracted using transurethral Heiss forceps. The patient experienced minimal blood loss and was discharged the following day, reporting relief from symptoms.

Conclusions: Unintentional NuvaRing® placement in the bladder is an extremely rare event that healthcare providers should consider when patients present with urinary symptoms and pelvic pain. Pelvic ultrasound is an efficient diagnostic tool, possibly averting the need for further imaging techniques. Cystoscopy remains the preferred method for diagnosis and treatment. This video report illustrates an effective technique for NuvaRing ® extraction, especially when appropriate graspers are unavailable. Adequate instruction on NuvaRing® insertion should always be emphasised.

Background: Laparoscopic myomectomy is increasingly considered the gold standard uterine preserving procedure and has well documented benefits over the open approach. Barriers that women have in accessing the most appropriate treatment need to be addressed to ensure optimal patient care and outcomes.

Objectives: To analyse rates of open and laparoscopic myomectomy at a large NHS trust and identify how many cases could potentially have been performed laparoscopically, and any variation between sites.

Materials and methods: A retrospective review of preoperative imaging reports and a surgical database containing information for all myomectomies performed between 1st January 2015 and 31st December 2022.

Main outcome measures: Number of procedures suitable for alternative surgical approach; length of hospital stay; estimated blood loss; cost differences.

Results: 846 myomectomies were performed; 656 by laparotomy and 190 by laparoscopy. 194/591 (32.8%) open myomectomies could have been performed laparoscopically and 26/172 (15.1%) laparoscopic myomectomies may have been better performed via an open approach. Length of hospital stay, and estimated blood loss were significantly higher in the open group. Had cases been performed as indicated by pre-operative imaging, the cost differences ranged from -£115,752 to £251,832.

Conclusions: There is disparity in access to the gold standard care of laparoscopic myomectomy. Due to multifactorial reasons, even at sites where the rate of laparoscopic myomectomy is high, there is still underutilisation of this approach. It is clear that there is scope for change and "levelling up" of this imbalance.

What is new?: Robust pathways and guidelines must be developed, and more laparoscopic surgeons should be trained to optimise care for women with fibroids.

Background: Reproductive surgery has long been neglected and is perceived to be simple surgery that can be undertaken by all gynaecologists. However, given the ever-expanding knowledge in the field, reproductive surgery now comprises surgical interventions on female reproductive organs that need to be carefully planned and executed with consideration given to the individuals symptoms, function of the organ and fertility concerns.

Objectives: To discuss the different perspectives of reproductive surgeons and other gynaecological surgeons, e.g., gynaecological oncologists, and advanced minimally invasive surgeons, regarding diagnosis and management of pelvic pathology that affects reproductive potential. Furthermore, to highlight the gaps in knowledge and numerous controversies surrounding reproductive surgery, while summarising the current opinion on management.

Materials and methods: Narrative review based on literature and the cumulative experience of the authors.

Main outcome measures: The paper does not address specific research questions.

Conclusions: Reproductive surgery encompasses all reproductive organs with the aim of alleviating symptoms whilst restoring and preserving function with careful consideration given to alternatives such as expectant management, medical treatments, and assisted reproductive techniques. It necessitates utmost technical expertise and sufficient knowledge of the female genital anatomy and physiology, together with a thorough understanding of and respect to of ovarian reserve, tubal function, and integrity of the uterine anatomy, as well as an up-to-date knowledge of alternatives, mainly assisted reproductive technology.

What is new?: A holistic approach to infertile women is only possible by focusing on the field of reproductive medicine and surgery, which is unattainable while practicing in multiple fields.

Background: Isthmoceles are a growing clinical concern.

Objectives: To evaluate the accuracy of diagnosis of isthmoceles by imaging and to correlate the dimensions with clinical symptoms and histopathology.

Materials and methods: Prospective study of women (n=60) with ≥1 C-section undergoing hysterectomy. Isthmoceles were measured by imaging before surgery and macroscopically on the specimen after hysterectomy, followed by histological analysis.

Main outcome measures: Accuracy of isthmocele diagnosis, correlation with clinical symptoms, and histopathological findings.

Result: By imaging, isthmoceles were slightly deeper (P=0.0176) and shorter (P=0.0045) than macroscopic measurements. Differences were typically small (≤3mm). Defined as an indentation of ≥2 mm at site of C-section scar, imaging diagnosed 2 isthmoceles consequently not seen by histology and missed 3. Number of prior C-sections increased isthmocele severity but neither the incidence nor the remaining myometrial thickness (RMT) did. Severity correlated positively with symptoms and histology. However, clinical use was limited. Histological analysis revealed presence of thick wall vessels in 100%, elastosis in 40%, and adenomyosis in 38%. Isthmocele lining was asynchronous with the menstrual phase in 31%.

Conclusions: Dimensions of isthmoceles by imaging were largely accurate with occasionally large differences observed. Number of C-sections did not increase isthmocele incidence, only severity. Indication for surgery remains clinical, considering dimensions and symptoms.

What is new?: Dimensions of isthmoceles should be confirmed before surgery since uterine contractions might change those dimensions. Symptoms increase with dimensions of isthmoceles but are not specific. Endometrial lining within the isthmocele can be asynchronous with the menstrual phase.

Introduction: Fertility-sparing treatments are increasingly used in patients with early-stage cervical cancer. The residual shortened cervix might increase the risk of preterm birth. When a vaginal cerclage is not technically feasible, a laparoscopic transabdominal cerclage (LAC) could be offered before or after conception. In this article, we show how to safely perform a post-conceptional LAC in patients with insufficient residual cervical length for vaginal cerclage.

Methods: A 34-year-old patient in the twelfth week of gestation who previously underwent repeated conisation for cervical cancer FIGO stage IA1 in 2021 was referred for cervical stenosis, which required a subsequent vaginal tracheoplasty. She became pregnant 3 months later. Ultrasound monitoring of the cervix showed a 15 mm cervical length. A step-by-step LAC in a pregnant woman was performed. Results: The Doppler velocimetry of the uterine arteries at the end of the procedure was normal. No intraoperative or postoperative complications were reported. The estimated blood loss was 100 mL and the total operative time of 120 min. The patient was discharged on the third postoperative day. A caesarean section was performed at 36 weeks of gestation for spontaneous contractions with excellent obstetric (male, 2860 gr) and neonatal outcomes.

Conclusion: LAC in pregnancy, although made more difficult due to the size of the uterus, is a safe and feasible procedure combining the advantages of minimally invasive surgery with excellent obstetric result.

Learning objective: In this video is shown how to perform a post-conceptional transabdominal laparoscopic cerclage in a young woman with no sufficient cervical length for a vaginal approach.

Endometriosis is a complex and chronic gynaecological disorder that affects millions of women worldwide, leading to significant morbidity and impacting reproductive health. This condition affects up to 10% of women of reproductive age and is characterised by the presence of endometrial-like tissue outside the uterus, potentially leading to symptoms such as chronic pelvic pain, dysmenorrhoea, dyspareunia, and infertility. The Montreux summit brought a number of experts in this field together to provide a platform for discussion and exchange of ideas. These proceedings summarise the six main topics that were discussed at this summit to shed light on future directions of endometriosis classification, diagnosis, and therapeutical management. The first question addressed the possibility of preventing endometriosis in the future by identifying risk factors, genetic predispositions, and further understanding of the pathophysiology of the condition to develop targeted interventions. The clinical presentation of endometriosis is varied, and the correlation between symptoms severity and disease extent is unclear. While there is currently no universally accepted optimal classification system for endometriosis, several attempts striving towards its optimisation - each with its own advantages and limitations - were discussed. The ideal classification should be able to reconcile disease status based on the various diagnostic tools, and prognosis to guide proper patient tailored management. Regarding diagnosis, we focused on future tools and critically discussed emerging approaches aimed at reducing diagnostic delay. Preserving fertility in endometriosis patients was another debatable aspect of management that was reviewed. Moreover, besides current treatment modalities, potential novel medical therapies that can target underlying mechanisms, provide effective symptom relief, and minimise side effects in endometriotic patients were considered, including hormonal therapies, immunomodulation, and regenerative medicine. Finally, the question of hormonal substitution therapy after radical treatment for endometriosis was debated, weighing the benefits of hormone replacement.

Background: The capabilities of minimally invasive surgery, either as conventional laparoscopy, or as robotic surgery, have increased to an extent that it enables complex operations in the field of gynaecological oncology.

Objective: To document the role of minimally invasive gynaecological surgery in cancer.

Materials and methods: A review of the literature that shaped international guidelines and clinical practice.

Main outcome measures: Current guidelines of major international scientific associations and trends in accepted clinical practice.

Results: In recent years, evidence on oncologic outcome has limited the role of minimally invasive techniques in cervical cancer, while the treatment of early endometrial cancer with laparoscopy and robotic surgery has become the international standard. In ovarian cancer, the role of minimally invasive surgery is still limited. Current evidence on perioperative morbidity underlines the necessity to implicate minimally invasive techniques whenever possible.

Conclusion: The optimal surgical route for the treatment of gynaecological cancer remains in many cases controversial. The role of minimally invasive surgery remains increasing in the course of time.

What is new?: This comprehensive review offers an entire perspective on the current role of minimally invasive surgery in gynaecological cancer therapy.

Background: Congenital uterine anomalies (CUA) can be associated with impairments of early and late pregnancy events.

Objective: To assess the impact of CUA on reproductive outcomes in pregnancies conceived spontaneously or after assisted reproduction.

Materials and methods: Systematic review and meta-analysis of cohort studies comparing patients with CUA versus women with normal uterus. A structured literature search was performed in leading scientific databases to identify prospective and retrospective studies. The Newcastle-Ottawa scale, adapted to AHRQ standards, was used to assess the risk of bias. Pooled odds ratios (OR) were calculated. Publication bias and statistical heterogeneity were assessed, and meta-regression was used to analyse the heterogeneity.

Main outcome measures: Miscarriage, ectopic pregnancy, placental abruption, term, and premature rupture of membranes (PROM), malpresentation at delivery, preterm delivery prior to 37, 34 and 32 weeks, caesarean delivery, intrauterine growth restriction/small for gestational age, foetal mortality and perinatal mortality.

Results: 32 studies were included. CUAs increased significantly the risk of first/second trimester miscarriage (OR:1.54;95%CI:1.14-2.07), placental abruption (OR:5.04;3.60-7.04), PROM (OR:1.71;1.34-2.18), foetal malpresentation at delivery (OR:21.04;10.95-40.44), preterm birth (adjusted OR:4.34;3.59-5.21), a caesarean delivery (adjusted OR:7.69;4.17-14.29), intrauterine growth restriction/small for gestational age (adjusted OR:50;6.11-424), foetal mortality (OR:2.07;1.56-2.73) and perinatal mortality (OR:3.28;2.01-5.36).

Conclusions: CUA increases the risk of complications during pregnancy, delivery, and postpartum. Complications most frequent in CUA patients were preterm delivery, foetal malpresentation, and caesarean delivery.

What is new?: Bicornuate uterus was associated with the highest number of adverse outcomes, followed by didelphys, subseptate and septate uterus.
