离体猪肾包膜下积液的声像图研究

Study of the Ultrasonography of Dropsy under Caplus Fibroso in Isolated Pig Ren

目的 观察分析当离体猪肾盂内压力短时间内急剧升高而致液体外渗部位、实物及声像图改变。方法 用注射器经输尿管向 4只离体猪肾盂分别注入蒸馏水观察离体猪肾及其声像图的表现和液体外渗部位。结果 (1)离体猪肾声像图与活体人肾极相似。 (2 )外渗液位于离体猪肾非肾门侧包膜下 ,且多先发于上、下极 ,肾包膜薄而透明、类似烫伤的小水泡状且随压力增大而扩大呈水囊状 ,直至破裂。 (3)离体猪肾肾包膜下积液声像图与活体人肾中由结石性输尿管急性梗阻引起肾盂内压力急剧升高而致尿液外渗声像图极相似。结论 离体猪肾声像图与活体人肾声像图具有可比性 ;

Objective To observe and analysize the changes of isolated pig ren and it's ultrasonography and the situation where the liquid gathered just when the pressure quickly raised in isolated pig ren pelvis. It helps clinical ultrosound accturely diagnose and scelect the best measuer. Methods 1. Preliminary test was perfromed in isolated pig ren with fresh pork wrapped. 2. To observe the changes of isolated pig ren and it's ultrosonography and the situation where the liquid grathered after isolateded pig ren pelvis were poured the liquid through ureter by injecter. Results 1. The preliminary test showed that the ultrosonography of isolated pig ren equal to the one of people ren. 2. The liquid was gathered under capsula fibroso. It become large from pubble to cyst with the pressure raising. 3. The ultraosonography of dropsy under capsula fibroso equal to the one of people ren by acute lithureteria obstruction. Conclusion The test is a evidence that dropsy under capsula fibroso is aprotective theory when the pressure quickly raise. It can helpclinical ultrasound diagnosis the situation where the liquid gathered and select the best measure
