The functional significance of renographic delay in excretion observed in connection with chiefly unilateral "physiologic" hydronephrosis of pregnancy was analyzed in 10 cases, The delay was found to be entirely or predominantly due to the reservoir effect of the dilated urinary tract. A moderate reduction of urinary flow on the affected side was suggested to contribute to the impairment in only 3 of the 10 cases. Interpretation of the degree of urinary obstruction as judged by renography should be cautious. This applies especially to the assessment of complete obstruction, which should be diagnosed only after considering the reservoir effect of the dilated tract.
对10例主要与妊娠单侧“生理性”肾积水相关的排泄期肾图延迟的功能意义进行了分析。发现这种延迟完全或主要是由于扩张的尿路的储尿作用。在10例中，仅3例提示患侧尿流适度减少是造成损害的原因。通过肾图判断尿路梗阻程度时应谨慎。这尤其适用于完全性梗阻的评估，只有在考虑扩张尿路的储尿作用后才能诊断。
