摘　　要：目的 比较X线数字断层融合（DTS）技术与尿路平片（KUB）在泌尿系结石诊断方面的应用价值.方法 对青岛大学附属医院2011年2月至2012年2月有肾绞痛伴血尿且非增强螺旋CT证实泌尿系结石的患者共80例,其中结石总数为138个,根据患者自愿原则,对其肠道准备前后各做一次KUB和DTS检查,然后观察记录各种情况下发现结石的数量及其所占比例,即记录显示结石的敏感度.统计学方法选用四格表卡方检验,比较肠道准备前后DTS、KUB差异有无统计学意义;肠道准备前DTS和KUB差异有无统计学意义;肠道准备后DTS和KUB差异有无统计学意义;肠道准备前DTS和肠道准备后KUB差异有无统计学意义;肠道准备后DTS和肠道准备前KUB差异有无统计学意义.结果 肠道准备前后DTS与肠道准备前后KUB的诊断结石的敏感度为94.2％、96.4％、47.8％和66.7％.除肠道准备前后DTS诊断敏感度差异无统计学意义外,其余5种情况下差异均有统计学意义.结论 相对于常规KUB而言,DTS检查几乎不受肠道气体的影响.DTS成像对结石的检出率明显高于KUB,达90％以上,并与KUB具有相同的定位功能.Objective To investigate the value of X-ray digital tomosynthesis （DTS in the diagnosis of urinary stones compared with kidney ureter bladder radiography.Methods Between February 2011 and February 2012,80 consecutively enrolled patients with urinary stones proved by UMDCT,the total number of which was 138,underwent additional DTS and KUB （kidney,ureter and bladder） then the number of stones and the proportions （the sensitivity of detecting stones） were recorded under all kinds of circumstances.Any two cases were selected in comparison with each other among the following four cases （DTS and KUB before and after bowel preparation）.The data from all cases were statistically processed by chi-square test of four-fold table.Results The diagnostic sensitivity of DTS before and after bowel preparation,KUB before and after preparation were 94.2%,96.4%,47.8% and 66.7%,respectively.No significant differences between DTS before bowel preparation and DTS after bowel preparation were found.Significant differences were observed in other five ways.Conclusion DTS is hardly affected by intestinal gas,feces and bones compared with KUB.Use of DTS results in improved detection rate and definition of stones with the same positioning function as KUB.
