The aims of our study are to evaluate ureterovesical jet flow Doppler ultrasound (US) in patients with residual ureteral stone after extracorporeal shock wave lithotripsy (ESWL) and to compare with unobstructed contralateral ureter. Patients who have residual ureteral stone in intravenous pyelography (IVP) and/or computed tomography (CT) after ESWL and unobstructed contralateral ureter in 20 patients were prospectively evaluated with Doppler US. The mean peak velocity of the Doppler waveforms was obtained on the residual ureteral stone and contralateral non-obstructed ureter (17.10 +/- 20), (56.0 +/- 32), respectively (P < 0.05). In conclusion, due to the absence of contraindications and side-effects, Doppler US is sensitive and highly specific that can contribute significantly to the diagnosis of residual ureteral stone after ESWL. It can replace IVP and/or CT, in condition where IVP is undesirable and in addition Doppler US can supply a functional investigation of the obstructed ureter.
我们研究的目的是评估体外冲击波碎石术（ESWL）后残留输尿管结石患者的输尿管膀胱喷射流多普勒超声（US），并与对侧通畅的输尿管进行比较。对20例在ESWL后静脉肾盂造影（IVP）和/或计算机断层扫描（CT）显示有残留输尿管结石且对侧输尿管通畅的患者进行了多普勒超声前瞻性评估。分别在残留输尿管结石处和对侧无梗阻输尿管处获得多普勒波形的平均峰值速度，分别为（17.10±20）和（56.0±32）（P<0.05）。总之，由于无禁忌证和副作用，多普勒超声敏感且特异性高，可对ESWL后残留输尿管结石的诊断有显著帮助。在IVP不可行的情况下，它可替代IVP和/或CT，此外，多普勒超声还可对梗阻输尿管进行功能检查。
