摘要
目的:通过MSCT平扫重建后再行静脉肾盂造影(IVP)检查联合运用,探究单纯MSCT平扫与MSCT多平面重建(MPR)+IVP联合检查对输尿管阴性小结石的诊断价值。方法:选择2016年4月~2017年3月我院收治的68例临床B超可疑输尿管结石而腹平片(KUB)检查未见发现结石的患者为研究对象,随机分为对照组和研究组。对照组和研究组患者分别进行MSCT平扫与MSCT多平面重建+IVP检查对比分析,观察两组患者的输尿管阴性结石的部位、数目等改变,统计MSCT平扫与MSCT多平面重建+IVP检查对输尿管阴性小结石的诊断率。结果:(1)以输尿管镜检查的结果作为确诊标准,两组患者的结石分布情况方面,与对照组相比较,研究组位于输尿管上段较为显著,两者之间差异具有统计学意义(P<0.05),而位于输尿管中段及下段无统计学差异(P>0.05);(2)对照组34例患者中,共检查出28个结石,其中有10个结石位于输尿管上段,有9个结石位于输尿管中段,有9个结石位于输尿管下段;研究组34例患者中,共检查出43个结石,其中有17个结石位于输尿管上段,有11个结石位于输尿管中段,有15个结石位于输尿管下段;且与对照组相比较,研究组被检出的结石数目显著增多,两者之间具有统计学差异(P<0.05);(3)对照组34例患者中,被确诊为输尿管阴性小结石的患者有27例,确诊率为79.41%,研究组34例患者中,被确诊为输尿管阴性小结石的患者有33例,确诊率为97.06%,两者之间具有统计学差异(x^2=7.925,P=0.019)。结论:多层螺旋CT多平面重建+IVP检查对输尿管阴性小结石的诊断率高,给广大患者及医院带来巨大的社会效益及经济效益,填补本地区的空白。
Objective：To reconstruct the MSCT and reconstruct the intravenous pyelography（IVP）,so as to investigate the diagnostic value of simple MSCT plain scan and MSCT multiplanar reconstruction（MPR）＋IVP combined examination for ureteral negative calculi.Methods：FromApril 2016 to March 2017,68 patients with clinical refractory ureteral calculi were selected and the patients with no stones were examined.The patients were randomly divided into control group and study group group.In the control group and the study group,MSCT scan and MSCT multiplanar reconstruction＋IVP were compared and analyzed.The location and number of ureteral negative stones in the two groups were observed.The MSCT scan and the MSCT multiple plane reconstruction＋IVP Diagnostic rate of ureteral negative calculi.Results：（1）The results of ureteroscopy were the diagnostic criteria.The distribution of stones in the two groups was significantly higher than that in the control group（P〈0.05）,and the difference between the two groups was statistically significant（P 〈0.05）（P〉0.05）.（2） Among the 34 patients in the control group,28 stones were examined.Among them,10 stones were located in the upper part of the ureter,and 9 stones were located in the middle of the ureter,and there were no more than two stones in the ureter 9stones were located in the ureteral lower part of the study group of 34 patients,a total of 43 stones were examined,of which 17 stones inthe upper ureter,11 stones in the middle of the ureter,15 stones in the lower ureter; and control group（P〈0.05）.（3） Among the 34 patients in the control group,27 patients were diagnosed as ureteral negative calculi,and the number of stones was significantly higher than that of the control group（P〈0.05）（x-2= 7.925,P=0.019）,and the rate of diagnosis was 97.06%.There was a significant difference between the two groups（x2= 7.925,P=0.019）.Conclusion：The multislice spiral CT multiple plane reconstruction＋IVP examination of the diagnosis of ureteral negative stones was relatively high,which could give the majority of patients and hospitals to bring huge social and economic benefits.
