| 目的 观察尿道中段活动度与括约肌弹性用于诊断女性压力性尿失禁(SUI)的价值。方法 前瞻性纳入97例女性患者,包括52例SUI(SUI组)及45例非SUI(对照组)。采用盆底超声于静息态与最大瓦尔萨尔瓦动作下进行扫查,测量膀胱颈移动度(BND)、尿道中段上下活动度(UM上下)、尿道中段前后活动度(UM前后)、尿道中段前壁括约肌弹性参数(ΔE前壁)及尿道中段后壁括约肌弹性参数(ΔE后壁)。比较组间一般资料及上述超声参数,评估其诊断SUI的效能。结果 组间BND、UM上下、ΔE前壁、ΔE后壁及会阴侧切术史占比差异均有统计学意义(P均＜0.05);其中,UM上下、ΔE前壁及ΔE后壁均与女性SUI存在相关性(rs=0.231、-0.533、-0.428,P均＜0.05)。以单一UM上下、ΔE前壁、ΔE后壁及三者联合诊断SUI的曲线下面积(AUC)分别为0.634、0.820、0.748及0.867;三者联合的AUC均显著大于各单一参数(P均＜0.001)。结论 联合应用尿道中段活动度与括约肌弹性参数有助于诊断女性SUI。 |

| Objective To observe the value of middle urethral motion and sphincter elasticity for diagnosing female stress urinary incontinence (SUI). Methods Totally 97 female patients, including 52 with SUI (SUI group) and 45 without SUI (control group) were prospectively enrolled. Pelvic floor ultrasound was performed under resting state and the maximum Valsalva maneuver, respectively, and bladder neck mobility (BND), upper-lower mobility of middle urethra (UMupper-lower), anterior-posterior mobility of middle urethra (UManterior-posterior), elasticity parameter of the anterior wall of middle urethral sphincter (ΔEanterior wall), as well as elasticity parameter of the posterior wall of middle urethral sphincter (ΔEposterior wall) were measured. Patients’ general data and the above ultrasound parameters were compared between groups, and the efficacy of them for diagnosing SUI was analyzed. Results Significant differences of BND, UMupper-lower, ΔEanterior wall and ΔEposterior wall, of also the proportion of lateral episiotomy history were found between groups (all P＜0.05). Among them, UMupper-lower, ΔEanterior wall and ΔEposterior wall were all correlated with female SUI (rs=0.231, -0.533, -0.428, all P＜0.05). The area under the curve (AUC) of UMupper-lower, ΔEanterior wall, ΔEposterior wall and their combination for diagnosing SUI was 0.634, 0.820, 0.748 and 0.867, respectively. The AUC of the combination was significantly higher than that of each parameter alone (all P＜0.001). Conclusion The combination of middle urethral motion and sphincter elasticity was helpful for diagnosing female SUI. |
