Studies were made peroperatively in a patient with incomplete ureteral duplication. Bipolar extracellular EMG-leads were taken from both pelvices, both ureteral segments and from the common ureter. Simultaneously pressure measurements were made in the pelvices. Function of the two pelvi-ureteral units were shown to be autonomous. Simultaneous action potentials and pressure waves were observed in each pelvis. Not every pelvic impulse was transmitted to the corresponding ureter, but when transmission did occur, the conduction rate was constant. Impulses from both ureteral branches were conducted distally to the common ureteral trunk, but impulses from the dilated segment had not the same quality (amplitude) as those from the non-dilated segment. Antiperistalsis was not observed. There was a measurable pressure difference between the two segments.
对一名输尿管重复畸形不完全患者进行了术中研究。双极细胞外肌电图电极取自两个肾盂、两个输尿管段和共同输尿管。同时对肾盂进行压力测量。结果显示两个肾盂输尿管单元的功能是自主的。在每个肾盂中观察到同步动作电位和压力波。并非每个肾盂冲动都能传导至相应的输尿管，但当传导发生时，传导速率是恒定的。来自两个输尿管分支的冲动向远端传导至共同输尿管干，但来自扩张段的冲动与未扩张段的冲动质量（幅度）不同。未观察到反蠕动。两个段之间存在可测量的压力差。
