Purpose:
The aim of this study was to explore differences in the bladder neck configuration and segmental urethral mobility during the cough stress test (CST) in the supine and standing positions between women with and without stress urinary incontinence (SUI).
Methods:
This prospective study included 100 control women and 100 incontinent women who had a CST with transperineal ultrasonography. The bladder neck configuration and urethral mobility were described in terms of urethral funneling, bladder neck descent (BND), retrovesical angle (RVA), urethral rotation angle, and urethral mobility at six points along the urethra (vectors 1 to 6). The two groups’ ultrasound findings in the two positions were compared.
Results:
Valid data were collected from 78 control women and 90 women with SUI. Significant differences were found in age and body mass index between the two groups (P<0.01). Urethral funneling was found in 33 women (36.7%) with SUI and five continent women (6.4%) and altered little in the standing position. In the standing position, the mean RVA significantly increased (160° to 179°, P<0.001) in the SUI group; The mean vector of points 1 to 6 significantly increased in the control group (all P<0.001). The RVA, BND, and vectors 1 to 4 were significantly greater (all P≤0.01) in women with SUI than without, in both positions.
Conclusion
Urethral funneling was an intrinsic anatomical characteristic relative to SUI. Weak upper- and mid-urethral support and an unstable connection between the trigone and proximal urethra were the anatomical signs of SUI.

Objective:To study the association between urethral configuration and mobility and female stress urinary incontinence (SUI).Methods:This was a prospective study in 176 women with pure SUI and 132 healthy women who undertook transperineal ultrasound in Second Xiangya Hospital between July 2017 and April 2020. Urethral funneling, bladder neck descent (BND) and rotation, retrovesical angle (RVA), and urethral mobility of 6 points along the urethra (Vectors 1 to 6) were measured by transperineal ultrasound during the cough stress test (CST). The differences between the two groups were tested using independent t-test. The relationship between ultrasound findings and SUI was analyzed by ROC curve and Logistic regression analysis. Results:Urethral funneling was found in 27.8% of women with SUI and 3.0% of controlled women.BND [(25.2±7.4)mm vs (21.5±8.6)mm], RVA [(171.5±26.3)° vs (159.4±26.6)°] and Vectors 1-6 [(2.97±0.89), (2.93±0.75), (2.67±0.67), (2.34±0.66), (2.27±0.67) , (2.36±0.69) vs (2.59±1.03), (2.54±0.83), (2.27±0.64), (1.99±0.50), (1.94±0.49), (2.05±0.53)] were significantly increased in SUI group (all P≤0.001). Logistic regression analysis yielded odds ratios of 10.06(95% CI=4.18-24.20), 2.71(95% CI=1.81-4.05) and 3.21(95% CI=2.01-5.14) for urethral funneling, Vector 3 and Vector 4 to predict for SUI, respectively. Conclusions:Transperineal ultrasound can be used to evaluate the real-time change of the bladder neck and urethral configuration and mobility in CST. Urethral funneling and mid-urethral hypermobility can be used to predict SUI.

Purpose:
This study compared the diagnostic performance of the Ovarian-Adnexal Reporting and Data System (O-RADS), the Risk of Malignancy Index 4 (RMI4), the International Ovarian of Tumor Analysis Logistic Regression Model 2 (IOTA LR2), and the IOTA Simple Rules (IOTA SR) in predicting the malignancy of adnexal masses (AMs).
Methods:
This retrospective study included 575 women with AMs between 2017 and 2020. All clinical messages, ultrasound images, and pathological findings were collected. Two senior doctors (group I) and two junior doctors (group II) used the four systems to classify AMs. The postoperative pathological diagnosis was used as the gold standard to evaluate the diagnostic efficiency. A receiver operating characteristic curve was used to test the diagnostic performance. The interrater agreement between the two groups was tested using kappa values.
Results:
Of all 592 AMs, 447 (75.5%) were benign, 123 (20.8%) were malignant, and 22 (3.7%) were borderline. The intergroup consistency test yielded kappa values of 0.71, 0.92, 0.68, and 0.77 for the O-RADS, RMI4, IOTA LR2, and IOTA SR, respectively. To predict malignant lesions, the areas under the curve of the O-RADS, RMI4, IOTA LR2, and IOTA SR systems were 0.90, 0.89, 0.90, and 0.86 for group I and 0.89, 0.87, 0.88, and 0.84 for group II, respectively. The O-RADS had the highest sensitivity (91.0% in group I and 84.8% in group II).
Conclusion
The four diagnostic systems could compensate for junior doctors’ inexperience in predicting malignant adnexal lesions. The O-RADS performed best and showed the highest sensitivity.

Objective:To study the agreements between transperineal ultrasound (TPUS) and endoanal ultrasound in assessing obstetrics anal sphincter injury (OASI), and to analyse the diagnostic efficacy of OASI in predicting AI relationship between OASI and anal incontinence (AI).Methods:A total of 217 women were prospectively recruited from the clinic in the Second Xiangya Hospital of Central South University from January 2021 to May 2022. Symptoms of AI were determined using the St Mark′s Incontinence Score (SMIS). TPUS and EAUS were performed by the same operator with the same machine on every participant for detecting OASI: OASI grades 3a, 3b, 3c, and 4 were performed according to the extent of the injuries in the anal sphincter complex. The angle of the defect in the external anal sphincter (EAS) was measured. A "significant EAS defect" was diagnosed as a defect affecting at least 2/3 of the length of the EAS with a defect angle of ≥30° in each slice.Ultrasound findings were compared between the two methods. The diagnostic efficacy of "ultrasound OASI" in predicting AI was analysed by logistic regression.Results:Of 217 women, twenty-eight (12.9%) suffered from AI with SMIS ranging from 5~20(11.9±4.5). On TPUS, 79 (36.4%) cases were suspected of OASI, that was 50 OASI 3a, 13 OASI 3b, and 16 OASI 3c/4. On EAUS, 78 (35.9%) cases were suspected of OASI that was 23 OASI 3a, 22 OASI 3b, 15 OASI 3c, and 18 OASI 4. Twenty-four "significant EAS defects" were diagnosed by TPUS and twenty-eight by EAUS, TPUS had excellent agreement with EAUS (weighted Kappa=0.91, P<0.001). Logistic regression analysis showed that "ultrasound OASI" was associated with AI symptoms. ROC curve analysis showed that the area under the curve (AUC) was 0.92, 0.87, 0.89, 0.92 for TPUS OASI 3b+ , EAUS OASI 3b+ , TPUS "Significant EAS defect" , and EAUS "Significant EAS defect" for predicting AI, respectively. Conclusions:TPUS has good agreement with EAUS in detecting OASI. OASI 3b+ and "significant EAS defect" on TPUS and EAUS had good performance in predicting AI symptoms.

OBJECTIVES:
International Ovarian Tumor Analysis (IOTA) working group proposed a logistic regression (IOTA LR2) model. It is served as a risk prediction model for benign and malignant adnexal tumors. This study aims to compare the diagnostic efficiency between the IOTA LR2 model and doctors' subjective assessment on diagnosing benign and malignant adnexal mass.
METHODS:
The ultrasonographic images of 616 adnexal masses were retrospectively analyzed by the senior doctors' group and the junior doctors' group using the IOTA LR2 model and subjective assessment. The postoperative pathological diagnosis was used as the gold standard to compare the diagnostic efficiency of the 2 methods.
RESULTS:
The area under the curves of subjective assessment and IOTA LR2 model for diagnosing malignant adnexal masses were 0.86 and 0.90 for the senior doctors' group and 0.79 and 0.88 for the junior doctors' group, respectively. The sensitivity and specificity of subjective assessment for diagnosing the malignant adnexal masses were 81.0% and 91.3% for the senior doctors' group and 70.1% and 88.7% for the junior doctors' group, respectively. The sensitivity and specificity of the IOTA LR2 model for diagnosing the malignant adnexal masses were 79.6% and 88.1% for the senior doctors' group, and 79.6% and 81.7% for the junior doctors' group, respectively.There were no significant difference in the sensitivities between the senior doctors' group and junior doctors' group using the IOTA LR2 model and the senior doctors' group using subjective assessment (both P>0.05).
CONCLUSIONS
The diagnostic efficiency of the IOTA LR2 model is equal to the senior doctors' experiences. This model can help junior doctors to reduce the missed diagnosis of malignant adnexal masses.
