本文报道应用彩色多普勒观察输尿管开口喷尿４６例，其中正常受试者２４例，输尿管结石２２例。正常受试者的双侧输尿管开口喷尿形态、频率和喷射方向对称。在输尿管结石病人中，有１７例输尿管的开口喷尿异常，特点是喷尿消失、喷尿形态改变和频率减少，与正常组比较，相差极显著（Ｐ＜０．０１）。彩色多普勒观察输尿管开口喷尿优于二维超声和双功多普勒，它是判定输尿管梗阻性疾病的重要筛选工具。
This article reports the use of color Doppler observation ureter opening ureter 46 cases, of which 24 were normal subjects, ureteral calculi in 22 cases. Bilateral ureteral ureter open normal urinary morphology, frequency and jet direction of symmetry. In patients with ureteral calculi, there were 17 cases of abnormal ureteric ureteric opening, characterized by extinction of the urine, morphological changes and frequency of excretion of urine, compared with the normal group, a significant difference (P <0.01). Color Doppler observation of ureteropelvic urinary incontinence is superior to two-dimensional ultrasound and duplex Doppler, it is an important screening tool to determine the ureteral obstruction disease.
