目的探讨助力式(ETE)及声力式弹性成像技术(NTQ)在压力性尿失禁(SUI)患者尿道括约肌弹性改变的应用研究。方法通过经会阴超声应用助力式弹性成像技术及声触诊组织量化技术(VTQ)检测191例女性尿道括约肌,其中SUI组68例,对照组A(同SUI年龄段无SUI女性)62例,对照组B(未育无SUI女性)61例,记录图像及测量相关数值进行分析统计。结果 ETE评4~5分者,SUI组54.4%(37/68),对照组A 43.5%(27/62),对照组B 18.0%(11/61);VTQ均值,SUI组(2.213±0.557)m/s,对照组A(2.027±0.337)m/s,对照组B(1.961±0.334)m/s,三组互相比较差异均有统计学意义(P<0.05)。结论随着生育及年龄增长,女性尿道括约肌硬度增加,特别是SUI患者尿道括约肌回声薄厚不均,硬度增加更为明显,考虑与SUI的发病有关,弹性成像技术对SUI的诊断有所帮助。
Objective To investigate the application of ETE and NTQ in urethral sphincter muscle resilience in patients with stress urinary incontinence (SUI). Methods 191 cases of female urethral sphincter were detected by the method of acoustic elastography and acoustic palpation (TEQ) via perineal ultrasound, including 68 cases of SUI and 62 cases of control group A (SUI without SUI) Group B (non-sterile SUI women) 61 cases, recording images and measurement-related values for analysis and statistics. Results ETE was observed in 4 to 5 patients in the SUI group (54.4%, 37/68), 43.5% (27/62) in the control group, 18.0% (11/61) in the control group, VTQ mean, and 2.213 ± 0.557 ) in control group (2.027 ± 0.337) m / s and control group B (1.961 ± 0.334) m / s, respectively. There were significant differences among the three groups (P <0.05). Conclusions With the increase of birth and age, the hardness of female urethral sphincter increased, especially the echo thickness of urethral sphincter in SUI patients increased more obviously.
