小儿内脏器官的形态学研究(六)——新生儿肾的形态学观察

观测30例(男18、女12)新生儿肾的位置、毗邻及其形态。主要结果:1.左肾位于腹后壁T_(11-12)～L_4上部之间,右肾位于腹后壁T_(12)上部～L_4中部之间,共长轴与脊柱平行。2.第12肋斜过两肾的上1/3部:左侧占63.33±8.80％,右侧占53.33±9.11％。3.新生儿肾为豆形,表面分叶明显,左肾大于右肾。4.肾门的形态分六型,肾唇的形态分五型。5.肾盂的形态分三型。本文对肾的毗邻、度量、肾门的内容排列、肾大、小盏的数目及肾皮质的厚度,肾柱的高度等进行了观测。

MORPHOLOGICAL OBSERVATIONS OF THE KIDNEYS IN NEWBORN

The position and relation of the kidneys were observed in 30 newborn cadavcrs(male 18,female 12), The main results are as follows. 1.The kidneys lie on the posterior wall behind the peritoneum, opposite the T11-12 to the upper part of L4 on the left and opposite the upper part of Ti2 to the middle part of L4 on the right. Their long axes are parallel with the vertebral column. 2.The upper 1/3 part of the kidneys passed obliquely by the twelfth rib respectively, left in 63.33+8.80%, right in 53.33+9.11%0 3. The kidneys are a pair of bean-shaped organs, the surface of which arc definitely lobed. The left kidney is larger than the right one. 4. The shape of the renal hilum is divided into 6 types. The shape of the renal lip falls into 5 types. 5.The shape of the renal pelvis is divided into 3 types. The adjacent relation of the kidneys, the size of the kidneys, the arrangement of the contents of the renal hilum, the number of the major and minor renal calyces, the thickness of the renal cortex and the high of the renal columns were observed and measured.
