【摘要】：目的探討腎靜脈結(jié)扎后腎臟不同部位超聲彈性改變的規(guī)律。方法 10只日本大耳白兔,分離、結(jié)扎右腎靜脈。結(jié)扎前、后15、30、60、90min時(shí),采用剪切波超聲彈性成像技術(shù)檢測腎臟中部腎臟皮質(zhì)、腎體及腎竇的楊氏模量平均值,各時(shí)間點(diǎn)各取1個(gè)腎臟進(jìn)行病理學(xué)研究。結(jié)果結(jié)扎右腎靜脈前,右腎皮質(zhì)、腎體及腎竇楊氏模量平均值分別為(15.93±1.70)、(13.41±1.24)kPa及(11.62±0.87)kPa;結(jié)扎后15 min分別為(34.84±4.91)、(26.90±3.59)kPa及(24.73±3.95)kPa,30 min時(shí)分別為(40.07±2.95)、(30.93±3.18)kPa及(30.15±3.53)kPa,60min時(shí)分別為(50.63±2.73)、(37.37±4.04)kPa及(32.88±3.47)kPa;90min時(shí)分別為(56.61±2.96)、(41.86±3.78)kPa及(35.35±2.78)kPa。腎靜脈結(jié)扎后腎臟不同部位楊氏模量平均值均顯著高于結(jié)扎前(P0.05),且隨時(shí)間延長逐漸增加,差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。腎皮質(zhì)楊氏模量平均值顯著高于腎體及腎竇(P0.05)。結(jié)論兔腎皮質(zhì)楊氏模量平均值均高于腎體及腎竇,結(jié)扎兔腎靜脈后90min內(nèi),腎皮質(zhì)、腎體及腎竇的楊氏模量平均值均逐漸增加。本研究提示,腎臟超聲彈性的研究中應(yīng)注意彈性測量區(qū)的規(guī)范統(tǒng)一,腎靜脈血流動(dòng)力學(xué)狀態(tài)可明顯影響腎臟超聲彈性測量值。
[Abstract]:Objective to investigate the changes of ultrasonic elasticity in different parts of kidney after ligation of renal vein.Methods Ten Japanese white rabbits were isolated and ligated right renal vein.The average Young's modulus of renal cortex, body and sinuses in the middle of the kidney was measured by shear wave elastography before ligation and at 60 minutes after ligation. One kidney was taken from each time point for pathological study.緇撴灉緇撴墡鍙寵偩闈欒剦鍓，
