The smooth-muscle cells of narrow segment in the ureter with congenital hydronephrosis in 5 cases were studied by transmission electron microscope. The result showed that the smooth-muscle cells of the narrow segment lack of myofilaments, dense body and dense patch in cells membrane. The above mentioned structures are functional deficient basis of the smooth-muscle cells in the ureter. Its deficiency results in the poor peristalsis function of the narrow segment of the ureter in congenital hydronephrosis. The cause and treatment principle in congenital hydronephrosis were discussed.
对5例先天性肾积水患者输尿管狭窄段的平滑肌细胞进行了透射电镜研究。结果显示，狭窄段的平滑肌细胞缺乏肌丝、致密体和细胞膜上的致密斑。上述结构是输尿管平滑肌细胞功能缺陷的基础。其缺陷导致先天性肾积水时输尿管狭窄段蠕动功能不良。文中讨论了先天性肾积水的病因及治疗原则。
