• W4311500500 abstract "Objective: To evaluate the measurements of urethral pressure profile (UPP) using air-charged catheters (ACC) in women with bladder neck obstruction and to preliminarily analyze the diagnostic value of UPP based on ACC for female bladder neck obstruction. Methods: Retrospective inclusion of 63 female patients with bladder neck obstruction diagnosed in the Department of Urology of Beijing Chao-yang Hospital from September 2020 to December 2021 were included as the observation group, and 45 female patients who came to the hospital due to lower urinary tract symptoms with non-bladder neck obstruction during the same period were selected as the control group. All patients received urodynamic examination and UPP examination based on ACC, and urethral pressure measurements [M (Q1, Q3)] were compared between the two groups and analyzed the predictive value of the relevant measurements for female bladder neck obstruction. Results: The age of the observation group was 61 (47, 67) years and body mass index (BMI) was 24.1 (21.6, 27.9) kg/m2, the age of the control group was 65 (58, 71) years and BMI was 25.0 (22.8, 27.6) kg/m2. The urethral pressure at the bladder neck and urinary sphincter position in the observation group were higher than control group[104.00 (83.00, 124.00) cmH2O (1 cmH2O=0.098 kPa) vs 42.00 (31.00, 65.50) cmH2O, 125.0 (107.0, 154.0) cmH2O vs 99.0 (77.0, 124.0) cmH2O, P<0.001]. The results of the receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of urethral pressure at the bladder neck position had the highest predictive value for female bladder neck obstruction (AUC: 0.946, 95%CI: 0.886-0.981, sensitivity: 87.3%, specificity: 91.1%), and the results of interaction point plot showed that the cut-off value was 72 cmH2O. The cut-off value of urethral pressure at the bladder neck position was used as positive cut-off value to predict female patients with bladder neck obstruction. Sixty-three patients with bladder neck obstruction were detected by UPP measurement using ACC in 59 cases (59/63, 93.7%) and the Kappa value was 0.774 (95%CI: 0.654-0.894), indicating that UPP had high consistency with pressure-flow study. Conclusions: UPP examination based on ACC can show the pressure values of the bladder neck and urethral sphincter position. When the urethral pressure of the bladder neck position is greater than 72 cmH2O, it is helpful for the diagnosis of female bladder neck obstruction and has guiding significance for the diagnosis and treatment of this disease.目的： 评估应用气态测压导管（ACC）的尿道压力测定（UPP）在女性膀胱颈梗阻患者中的各项测量值，分析基于气态测压系统的UPP对女性膀胱颈梗阻的诊断价值。 方法： 回顾性纳入2020年9月至2021年12月北京朝阳医院泌尿外科确诊的63例膀胱颈梗阻女性患者为观察组，另选取同时期因下尿路症状来院就诊为非膀胱颈梗阻的女性患者45例为对照组。全部患者均接受基于ACC系统的尿动力检查及UPP检查，比较两组患者尿道压力测量值［M（Q1，Q3）］，分析相关测量值对女性膀胱颈梗阻的预测价值。 结果： 观察组年龄61（47，67）岁，体质指数（BMI）为24.1（21.6，27.9）kg/m2；对照组年龄65（58，71）岁，BMI为25.0（22.8，27.6）kg/m2。观察组膀胱颈和尿道括约肌位置尿道压力均高于对照组［104.0（83.0，124.0）cmH2O（1 cmH2O=0.098 kPa）比42.0（31.0，65.5）cmH2O、125.0（107.0，154.0）cmH2O比99.0（77.0，124.0）cmH2O，均P<0.001］；受试者工作特征（ROC）曲线结果显示，膀胱颈位置尿道压力对女性膀胱颈梗阻的预测价值最高［曲线下面积（AUC）：0.946，95%CI：0.886~0.981，灵敏度为87.3%，特异度为91.1%］，交互点图显示其最佳阈值为72 cmH2O；将膀胱颈口尿道压力最佳阈值作为预测女性膀胱颈梗阻患者的阳性分界值，63例膀胱颈梗阻患者应用ACC行UPP检查检出膀胱颈梗阻59例（59/63，93.7%），Kappa值为0.774（95%CI：0.654~0.894），表明UPP测定与压力-流率诊断方法具有较高一致性。 结论： 基于ACC的UPP检查可显示膀胱颈口位置及尿道括约肌位置的压力数值，膀胱颈口尿道压力>72 cmH2O时有助于诊断女性膀胱颈梗阻。." @default.
