A colour Doppler ultrasound study of the ureterovesical was performed to define the normal features, variants and abnormalities of the ureteric stream by comparing 50 normal subjects and 19 subjects with renal colic due to ureteric stones. The examination included assessment of the frequency, intensity, morphology and symmetry of the ureterovesical stream. In normal subjects, the stream was either absent, especially in the case of fluid restriction (36%), present and symmetrical (34%) or asymmetrical (30%). In patients with ureteric stones, during a non-painful period and in the absence of obstruction on IVU, the stream was normal and symmetrical (9%) while during a painful period with obstruction on IVU, the ureteric stream was either absent (47%) or abnormal and asymmetrical (31%). A continuous stream, very suggestive of obstruction, was observed in 5 cases. Colour Doppler ultrasound is a new, simple method which may be helpful in the diagnosis of renal colic, particularly in cases in which the pyelocaliceal cavities are not dilated.
通过比较50名正常受试者和19名因输尿管结石导致肾绞痛的受试者，进行了一项输尿管膀胱彩色多普勒超声研究，以确定输尿管血流的正常特征、变异和异常情况。检查包括对输尿管膀胱血流的频率、强度、形态和对称性进行评估。在正常受试者中，血流要么不存在，尤其是在液体摄入受限的情况下（36%），要么存在且对称（34%）或不对称（30%）。在输尿管结石患者中，在无痛期且静脉肾盂造影无梗阻时，血流正常且对称（9%），而在静脉肾盂造影有梗阻的疼痛期，输尿管血流要么不存在（47%），要么异常且不对称（31%）。在5例中观察到持续血流，这非常提示存在梗阻。彩色多普勒超声是一种新的、简单的方法，可能有助于肾绞痛的诊断，特别是在肾盂肾盏未扩张的情况下。
