Flow of urine from the ureter into the bladder can be encountered during routine sonographic examination of the pelvis. The findings include a stream of hyperechogenic foci spurting into the bladder in real time with the production of a frequency shift during Doppler examination. We have demonstrated that visualization of this phenomenon, at least in part, reflects differences in density and associated compressibility changes between urine in the bladder and in the ureter, and need not be dependent upon flow velocity or other previously hypothesized parameters. The clinical utility of these reproducible and measurable phenomena is explored.
在骨盆常规超声检查期间可观察到尿液从输尿管流入膀胱的情况。其表现包括在实时超声检查中，一连串高回声灶喷入膀胱，且在多普勒检查时出现频移。我们已经证明，这种现象的可视化至少部分反映了膀胱和输尿管内尿液之间密度差异及相关的可压缩性变化，而不一定依赖于流速或其他先前假设的参数。本文探讨了这些可重复和可测量现象的临床应用价值。
