Abstract
In this paper, about the left lumber ectopic kidney of a 87-years-old Japanese woman, we observed the size of her kidney, the form of her renal hilum, and the form of her calicopelvic system. In addition, we measured the index of cortex and medulla (C/M), and examined the difference between the lumber ectopic and the normal kidney.
There was no significant difference in the size (length, width, thickness, weight), without the external form was the distorted oval of lumber ectopic kidney. The renal hilum was divided into the upper and lower parts by the septum consisted of the parenchyma of kidney. In the calicopelvic system of the left lumber ectopic kidney, an obstructive distension due to the oppression by branch of the renal vein was observed in the superior minor renal calices. It seemed that it was Fraley's syndrome. From the viewpoint of C/M in the lumber ectopic kidney, it was suggested that there was no difference in the renal function, because the C/M was within a normal range.
