Examination of the renal pelvis of late fetal and neonatal kidneys shows that in about one quarter of the calyces examined the arrangement is similat to that in the rat, the outer medulla being separated from the calyceal cavity by a very thin epithelium. It is suggested that this presents a vulnerable area through which intrarenal damage can occur as a result of vesico-ureteric reflux in the immature kidney.
对晚期胎儿和新生儿肾脏肾盂的检查显示，在所检查的大约四分之一的肾盏中，其结构与大鼠的相似，外髓质与肾盏腔之间被一层非常薄的上皮组织分隔开。有人认为，这是一个脆弱区域，在未成熟的肾脏中，膀胱输尿管反流可能会通过这个区域导致肾内损伤。
