  目的 探讨彩色多普勒超声引导下经皮穿刺注入高渗葡萄糖治疗单纯性肾囊肿时囊内最终的葡萄糖浓度及囊肿的大小对疗效的影响,为临床提供更有效利用高渗葡萄糖治疗中老年人单纯性肾囊肿依据。方法2008年3月~2013年3月以50%葡萄糖作为硬化剂连续治疗单纯性肾囊肿63例。在超声引导下,抽取一定量的囊液后注入小于抽出的囊液量50%的葡萄糖,如一次抽不尽,则通过多次注入高糖提高囊内葡萄糖浓度,尽可能使囊内葡萄糖浓度达到50%。囊肿内葡萄糖浓度计算方法:第一次抽出一定量的囊内液体后注入适量的50%葡萄糖,此时囊内葡萄糖浓度X1:X1={V1/(Vd1+V1)}×50%。其中Vd为首次抽吸囊内一定量液体后囊腔内残余囊液的量,Vd=穿刺前的容积(V0)一实际抽出的液体量(VE),V1为实际首次注入的葡萄糖的量(V1<VE)。
