连续观察３０具经福尔马林固定的成人腹部横断面标本，结果显示肾筋膜向外侧延伸和附着在肾门及其以下平面可分为四种类型：Ⅰ型在肾门平面左右侧出现率分别为２３．３３％和３０．００％，肾下极平面分别为３０．００％和３３．３３％；Ⅱ型在肾门平面的出现率左右侧分别为４０．００％和２６．６７％，肾下极平面分别为１０．００％和３．３３％；Ⅲ型在肾门平面的出现率左右侧分别为３３．３３％和４３．３３％，肾下极平面分别为６０．００％和６３．３３％；Ⅳ型少见，仅见于左肾门平面，出现率为３．３３％。肾门以上平面，肾前、后筋膜在肾外侧愈着。熟悉肾筋膜向外侧延伸和附着的情况，对腹膜后间隙积液扩散途径的认识和积液的定位鉴别诊断及临床处理具有重要意义。
Continuous observation of 30 formalin-fixed adult abdominal cross-sectional specimens, the results show that the extension of the renal fascia and attached to the kidney and the following plane can be divided into four types: type I appear on the left and right side of the renal portal Rates were 23.33% and 30.00% respectively, and the subrenal pole planes were 30.00% and 33.33% respectively. The incidences of type Ⅱ in the left and right renal hilar planes were 40.00% and 26.67% %, The level of the lower kidney were 10.00% and 3.33% respectively. The incidence of type Ⅲ was 33.33% and 43.33% on the left side and right side of the kidney and the level of the lower kidney was 60.00 % And 63.33% respectively. The type Ⅳ was rare, only seen in the left renal valve plane, the incidence was 3.33%. Renal above the plane, the anterior, posterior fascia in the kidney lateral more. Familiar with the extension and attachment of the renal fascia to the outside of the situation, the diffusion of peritoneal space fluid diffusion understanding of the differential diagnosis and treatment of effusion diagnosis and clinical treatment is of great significance.
