Abstract:

目的:研究融合肾锥体的发生情况及解剖结构,为经皮肾镜碎石取石术的精准穿刺提供解剖学依据。方法:2017年5月-2018年1月,共选取105个新鲜猪肾进行解剖。统计融合肾锥体的发生情况,包括融合肾锥体在上、中、下组肾盏中的发生率,中组肾盏不同程度融合肾锥体的特征及其比例,中组肾盏肾锥体融合的个数及其比例。结合组织切片对比研究融合肾锥体及肾柱内的血管分布。结果:融合肾锥体具有很高的发生比例,肾脏上下极尤为明显。上、下组肾盏的肾锥体常常发生大片状融合。中组肾盏以2个肾锥体融合多见,融合的程度则以重度多见。融合肾锥体内存在叶间动脉走行,但界限不清,且缺乏坚韧的结缔组织保护,常常发生变异。结论:融合肾锥体是肾脏常见的解剖结构,叶间动脉分布于融合肾锥体内。由融合肾小盏引导的常规经皮肾穿刺可能会导致融合肾锥体内异位叶间动脉的严重损伤
