Objective: To observe the pregnancy outcomes of patients with unexplained recurrent spontaneous abortion (URSA) after interventional treatment or expectant treatment. Methods: This prospective study followed up 398 patients with recurrent spontaneous abortion from March 2017 to September 2022 in seven hospitals. Among them, 267 patients were diagnosed with URSA, including 124 patients who were initially diagnosed in the interventional treatment hospital and 143 patients who were initially diagnosed in the expectant treatment hospital. All URSA patients were followed up for 33 months. Ongoing pregnancy rates were observed as main outcome indicators. Results: A total of 127 patients became pregnant, and 107 of them had sustained pregnancies, the ongoing pregnancy rate was 84.25% (107/127). The ongoing pregnancy rate was 86.11% (31/36) in the interventional treatment group and 83.52% (76/91) in the expectant treatment group, with no significant difference (P>0.05). During the follow-up, the ongoing pregnancy rates in the interventional treatment hospital and the expectant treatment hospital were 75.71% (53/70) and 94.74% (54/57), respectively, with a significant difference (P<0.05). The ongoing pregnancy rate after interventional treatment in the interventional treatment hospital was 82.76% (24/29), which was similar to the 94.00% (47/50) after expectant treatment in the expectant treatment hospital (P>0.05). Conclusion: The ongoing pregnancy rate of interventional treatment for URSA patients has not been significantly improved, suggesting that it may not be necessary to carry out this treatment.

Objective: To explore the feasibility of transvaginal core needle biopsy for pelvic masses under finger guidance during a vagino-recto-abdominal examination. Methods: The clinicopathological data and follow-up information of 29 patients with pelvic masses who underwent transvaginal core needle biopsy under finger guidance during a vagino-recto-abdominal examination at Affiliated Hospital of Southwest Medical University from January 2020 to July 2024 were collected, and the safety and diagnostic accuracy of the procedure were retrospectively analyzed. Results: (1) A total of 29 patients with pelvic masses were enrolled in this study, with a median age of 50 years (range: 29-73 years), and a median tumor diameter of 3.9 cm (range: 2.7-13.3 cm). Among these patients, 7 were newly diagnosed, and 22 were follow-up. The pre-procedure disease types included 21 patients (72%, 21/29) cervical cancer, 6 patients (21%, 6/29) epithelial ovarian cancer, and 2 patients (7%, 2/29) other suspected gynecologic tumors. (2) Among 29 patients with pelvic masses, 8 cases (28%, 8/29) were diagnosed with benign diseases according to core needle biopsy pathological findings, and 1 case suggested possible residual cervical cancer in the parametrial region by contrast-enhanced magnetic resonance imaging after radical chemoradiotherapy 3 months, while the result of core needle biopsy for this patient was negative, with follow-up after 1 year revealed progression of the lesion in the right parametrial area. Another patient underwent fine-needle aspiration cytology, which suggested gastrointestinal stromal tumor, requiring differentiation from endometriosis, and core needle biopsy pathology confirmed endometriosis, with follow-up at 6 months revealed no evidence of malignancy in this patient. The remaining 6 patients with benign diagnoses had follow-up periods exceeding 1 year without imaging or clinical evidence of local lesion progression or malignancy. Among the 21 patients (72%, 21/29) diagnosed with malignant tumors by core needle biopsy, 14 cases were suspected cases of residual or recurrent cervical cancer, 6 cases had advanced ovarian cancer, and 1 case had rectal cancer metastasis, with all biopsy diagnoses being consistent with preoperative clinical findings and imaging results. The overall diagnostic accuracy of the core needle biopsy was 97% (28/29). Among the 7 newly diagnosed patients, the diagnostic accuracy was 7/7, while it was 95% (21/22) for the 22 follow-up patients, with no statistically significant difference observed between the two groups (P=1.000). (3) All 29 patients with pelvic masses successfully underwent transvaginal core needle biopsy guided by vagino-recto-abdominal examination. Among them, 28 cases (97%, 28/29) reported tolerable pain during the procedure, while 1 case (3%, 1/29) experienced transient syncope at the end of the procedure due to pain, which resolved within seconds. Vaginal bleeding exceeding 50

Objective: To investigate the feasibility and value of nomogram based on base line clinical and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) characteristics for pretreatment predicting the depth of myometrial invasion and tumor grade of endometrioid endometrial carcinoma (EEC). Methods: Preoperative baseline clinical characteristics and DCE-MRI characteristics of 194 EEC patients were prospectively collected at Obstetrics and Gynecology Hospital, Fudan University from October 2020 to January 2022 and used as a training set. Univariate analysis was conducted to compare baseline clinical characteristics and DCE-MRI quantitative parameters [including tumor volume, and mean, median, and standard deviation of volume transfer constant (K^trans), rate constant (K_ep), extravascular extracellular volume fraction (V_e), and initial area under the enhancement curve (iAUC)] between patients with deep myometrial invasion (DMI) and those with superficial myometrial invasion (SMI), as well as between high-grade and low-grade EEC. Multivariate logistics regression analysis was used to identify independent predictors for the construction of nomogram. An independent external testing set comprising 127 EEC patients was retrospectively collected from Zhongshan Hospital, Fudan University and Zhongshan Hospital, Fudan University (Xiamen Branch). The area under the receiver operating characteristic curve (AUC) and decision curve analysis (DCA) were used for evaluating the model's predictive performance and clinical net benefit, respectively. Results: (1) The depth of myometrial invasion: univariate analysis showed that in the training set, the EEC patients with DMI differed significantly from those with SMI in clinical characteristics including higher proportion of postmenopausal state and overweight [body mass index (BMI)≥25 kg/m²], and abnormal levels of serum cancer antigen (CA)₁₂₅, CA₁₉₉, and human epididymis protein 4 (HE4), and in DCE-MRI quantitative parameters including tumor volume, and median, mean, and standard deviation of K^trans, median of V_e, as well as median, mean, and standard deviation of iAUC (all P<0.05). Multivariate analysis showed that the patient's menstrual status, BMI, CA₁₉₉, tumor volume, and mean of iAUC were independent predictors of the depth of myometrial invasion, and constructed the nomogram (recorded as Nomogram_1), achieving an AUC of 0.861 (95%CI: 0.803-0.919) in the training set. In the independent external testing set, the AUC was 0.876 (95%CI: 0.815-0.938), with corresponding sensitivity of 82.0%, specificity of 80.7%, accuracy of 81.1%, positive predictive value (PPV) of 65.3%, and negative predictive value (NPV) of 91.0% for predicting DMI. (2) The EEC grade: univariate analysis showed that in the training set, high-grade EEC patients differed significantly from low-grade EEC in

Objective: To describe the safety of using the Chinese-made robotic laparoscopic surgery system for laparoscopic sacrocolpopexy in the treatment of severe pelvic organ prolapse. Methods: A pilot descriptive clinical study was conducted, enrolling 16 severe pelvic organ prolapse patients at Peking University First Hospital from April 2023 to January 2024. Patients who consented to participate in this study underwent laparoscopic sacrocolpopexy for severe pelvic organ prolapse using Chinese-made robotic laparoscopic surgery system. Preoperative clinical basic data and perioperative data of the patients were collected, summarizing the data on perioperative bleeding and complications, and reviewed the surgical learning experience. The evaluation indicators related to the learning experience included: (1) efficiency evaluation: including equipment docking time, total surgery time, suturing time, mechanical arm operation time and hysterectomy time, which were timed and recorded during surgery; (2) equipment operability evaluation: including equipment operation task load assessment and intraoperative operation feeling score. The cumulative sum analysis method was used to quantify surgery time and fit the learning curve. Results: Sixteen patients were successfully enrolled and underwent surgery, including total hysterectomy with bilateral salpingo-oophorectomy or salpingectomy plus sacrocolpopexy, or sacrocolpopexy alone (for one case without uterus). The age of 16 cases was (56.7±7.6) years (ranged from 44 to 67 years), with body mass index of (25.4±2.5) kg/m². Concurrent procedures included anterior vaginal wall repair in 12 cases (12/16), posterior vaginal wall repair in 13 cases (13/16), tension-free vaginal tape obturator system in 1 case (1/16), and recto-uterine pouch hernia repair in 4 cases (4/16). The total surgery time was (355.8±91.1) minutes, with docking time at (6.7±4.9) minutes, robotic operative time at (267.6±81.4) minutes, robotic suturing time at (155.6±53.9) minutes, and hysterectomy time at (112.0±45.3) minutes. Learning curve analysis revealed inflection points at 6 cases for total surgery time (P<0.001, R²=0.944) and robotic operative time (P<0.001, R²=0.982), 5 cases for docking time (P<0.001, R²=0.989), and 6 cases for robotic suturing time (P<0.001, R²=0.907). Hysterectomy time had an inflection point at 5 cases (P=0.023, R²=0.700). Median blood loss was 30 ml (range: 10-1 000 ml), with severe bleeding in one patient (1/16). No conversions to open surgery or laparoscopy occurred, and no severe perioperative or postoperative complications were reported. Conclusion: The Chinese-made robotic laparoscopic surgery system demonstrates excellent short-time safety and ease of operation for laparoscopic sacrocolpopexy.

Objective: To evaluate the clinical value of high-risk human papillomavirus (HPV) viral load for the cervical cancer screening and triage of high-risk HPV positive populations without additional tests. Methods: (1) This study conducted a retrospective analysis of 29 720 women aged 35-64 years who received cervical cancer screening in Quanzhou, China, in 2021. Fourteen high-risk HPV types (including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) were detected for cervical cancer primary screening using hybrid capture-chemiluminescence method. High-risk HPV positive samples were further subjected to HPV 16/18 genotyping using hybrid capture-chemiluminescence method. Among them, HPV 16/18 positive women were directly referred to colposcopy, while the other 12 high-risk HPV positive samples were further subjected to liquid based cytology test. Those with abnormal or suspicious cytology were referred to colposcopy. Biopsies were taken for histopathological examination of suspicious or abnormal individuals under colposcopy. (2) Ten cases of colposcopy loss or refusal to undergo examination were excluded, and the data from the 29 710 cases were analyzed. The HPV viral loads of the other 12 high-risk HPV positive populations were focused and evaluated their HPV viral loads for further cervical intraepithelial neoplasia (CIN) Ⅱ and above lesions (CINⅡ⁺) triage in cervical cancer screening. Results: (1) Among 29 720 women, 2 487 women (8.37%, 2 487/29 720) were positive for high-risk HPV, including 807 women (2.72%, 807/29 720) were positive for HPV 16/18 and 1 680 patients (5.65%, 1 680/29 720) were positive for the other 12 high-risk HPV types. Among 1 680 women who tested positive for the other 12 high-risk HPV types, 573 patients were atypical squamous cell carcinoma of unclear significance or above, 346 patients were CIN Ⅰ, 122 patients were CIN Ⅱ-Ⅲ, 9 patients were squamous cell carcinoma patients, and 4 patients were adenocarcinoma in situ. The immediate risk of CIN Ⅱ⁺ in HPV 16/18 positive women (11.13%) was approximately four times higher than that of other 12 high-risk HPV positive women (2.74%). (2) Through the viral load analysis of the other 12 high-risk HPV types, we found that the viral load of the other 12 high-risk HPV provide a good value for the pathological results, with a clinical cutoff (CO) value of 11.21 relative light unit/CO (RLU/CO) for the CINⅡ⁺ detection. Except for HPV 16/18 positive patients, when the viral load values of the other 12 high-risk HPV types were greater than 10 RLU/CO, these patients had a higher risk of CINⅡ⁺, with a positive predictive value of 31.29%. CINⅡ⁺ was not found in any of the other 12 high-risk HPV positive with viral load values less than or equal to 10 RLU/CO. Conclusions: Using hybrid capture-chemiluminescence HPV tests for HPV 16/18 genotyping, combined with the viral loads (>10 RLU/CO) of th

Objective: To observe the safety and short-term efficacy of using an autologous fascia lata sling (AFLS) for tension-free mid-urethral sling (MUS) in the treatment of stress urinary incontinence (SUI). Methods: Between February 2022 and December 2023, 11 patients with SUI underwent AFLS-MUS. Preoperative data were recorded, including basic patient information and completion of urinary distress inventory 6 (UDI-6). During surgery, AFLS was harvested through a small incision using a tendon extractor, and used as a sling for transobturator or retropubic MUS. Perioperative indicators were recorded, including surgical approach, operation time, intraoperative blood loss, postoperative hospital stay, duration of catheterization, perioperative complications (Clavien-Dindo classification), and surgical costs. Follow-ups included outpatient physical examination at 2 months postoperatively, and telephone follow-up at 6 months, 1 year, and annually thereafter. Follow-up content included the presence or absence of urinary leakage symptoms, UDI-6, satisfaction, patient global impression of improvement (PGI-I), and complications. Results: The age of the 11 patients was (54.8±10.9) years (range: 41-72 years), with body mass index of (23.9±1.8) kg/m² (range: 21.4-27.3 kg/m²). All patients experienced urinary leakage after coughing, sneezing and physical activity, with positive SUI provocation tests. The preoperative UDI-6 was 50.0±21.6 (range: 16.7-79.2), the result of 1-hour pad test was (18.9±12.0) g (range: 2.5-71.2 g). Four cases underwent MUS only, with operation time of (98.0±13.3) minutes (range: 86-117 minutes), and intraoperative blood loss of (17.5±5.0) ml (range: 10-20 ml); 7 cases also underwent pelvic floor repair simultaneously. The postoperative hospital stay was (3.5±2.0) days (range: 2-9 days). The duration of catheterization was (4.5±3.8) days (range: 2-11 days), with postoperative urinary retention in three cases, one of which underwent sling release surgery due to severe postoperative voiding difficulty 1 week after MUS, with no other complications of Clavien-Dindo grade 2 or above. The cost of AFLS harvest plus MUS was (2 762±293) yuan. At the 2-month outpatient follow-up, all patients were free of urinary leakage symptoms, with UDI-6 of 2.3±1.9 (range: 0-8.3); satisfaction was "very satisfied" in 10 cases and "fairly satisfied" in 1 case, with PGI-I all being "much better", and pelvic examinations were normal. Telephone follow-up showed one case lost to follow-up, and the remaining 10 cases had follow-up time of (18.6±4.9) months (range: 7-26 months), all without urinary leakage, with UDI-6 of 2.7±2.6, satisfaction rated as "very satisfied", and PGI-I all "much better". Conclusion: This modified AFLS-MUS for the treatment of SUI shows good short-term efficacy and high safety in harvest site, with the need for more data accumulation and long-term follow-up.
