Abstract：Objective To explore the clinical value of conventional ultrasound and anterior chamber structural parameters in the diagnosis of stress urinary incontinence(SUI).Methods A retrospective study.Eighty postmenopausal women who underwent examination and treatment in our hospital from April 2021 to December 2023 were included.Based on their examination results,they were divided into the SUI group and non-SUI group.All women were examined using ultrasound at rest and during maximum Valsalva movement,recording the structural parameters of the anterior chamber,and analyzing the diagnostic value of these parameters for SUI using receiver operating characteristic(ROC)curves.Results According to routine ultrasound,58.82％of women in the SUI group had funnel formation at the internal urethral orifice and 73.53％had cystocele,which were higher than 28.26％and 30.43％in the non-SUI group(P＜0.05).There was no significant difference in detrusor thickness(DWT)between the two groups(P＞0.05).However,the resting urethral inclination angle(UTA)and PUA in the SUI group were higher than in the non-SUI group,and the BNP was lower than in the non-SUI group(P＜0.05).Under the maximum Valsalva maneuver,the URA and BND in the SUI group were greater than those in the non-SUI group,while the BNS was lower than in the non-SUI group(P＜0.05).The diagnostic AUC values for SUI using UTA,BNP,PUA,URA,BNS,and BND were 0.717,0.619,0.607,0.799,0.704,and 0.773,respectively.The combined diagnostic AUC was 0.911,with sensitivity and specificity of 89.1％and 82.5％,which were higher than individual diagnostic parameters.Conclusion Conventional ultrasound can measure anterior chamber structural parameters such as UTA,BNP,PUA,URA,BNS,and BND.Combining these parameters for SUI in Postmenopausal women diagnosis can improve diagnostic efficiency.
