摘　　要：目的探索单侧输尿管结石导致肾绞痛的CT特征。方法选取2013年12月至2017年1月于我院接受治疗的78例单侧输尿管结石患者为研究对象,将其设为观察组,同期在社区招募78名健康的志愿者作为对照组。同时依据结石的大小将观察组分为较大组(21例)、中等组(34例)以及较小组(23例)。依据结石的位置将观察组分为输尿管上段组(11例)、输尿管中段组(26例)和输尿管下段组(41例)。以及依据患者的疼痛程度将观察组分为轻度组(24例)、中度组(23例)和重度组(31例)。最后根据测量各组的双肾CT比值(双肾CT值较小值/较大值×100%)分析得出影响肾绞痛疼痛程度的因素。结果研究发现,结石较大组、中等组以及较小组患者的CT比值差异无统计学意义(P>0.05),且均小于对照组,差异具有统计学意义(P<0.05)。输尿管上段组、输尿管中段组和输尿管下段组患者的CT比值数据无统计学意义(P>0.05),且均小于对照组,差异明显且具有统计学意义(P<0.05)。轻度组患者CT比值大于中度组、重度组,中度组患者双肾CT比值大于重度组(P<0.05)。结论单侧输尿管结石易导致肾绞痛,其双肾的CT比值并不能判断结石的大小以及结石的位置,但是在一定程度上可以预测患者的疼痛度。Objective To explore the CT features of renal colic caused by unilateral ureteral calculi. Methods 78 patientswith unilateral ureteral calculi who were treated in our hospital from December 2013 to January 2017 were selected as the subjects,set it as observation group,in the same period, 78 healthy volunteers were recruited as control group.At the same time, according to the size of the stones, the observation group was divided into larger group （21 cases）, medium group （n=34）and group （n=23）. According to the location of the stones, the observation group was divided into upper ureter group （11 cases）, middle ureter group （n=26） and lower ureter group （n=41）.According to the degree of pain, the patients were divided into mild group （24 cases）, moderate group （n=23） and severe group （n=31）. Finally, according to the measurement of the ratio of CT to 100% （CT value of double kidney）, the factors affecting the degree of renal colic pain were analyzed.Results The study found that there was no significant difference in the CT ratio between the larger, middle and small groups （P〉0.05）, and all were less than the control group, the difference was statistically significant （P〈0.05）. There was no significant difference in CT ratio between the upper ureteral group, the middle ureteral group and the lower ureteral Segment （P〉0.05）, and all were less than the control group, the difference was statistically significant （P〈0.05）. In mild group, the CT ratio was higher than that in moderate group and severe group, and the ratio of CT between the two groups was higher than that in severe group （P〈0.05）. Conclusion Unilateral ureteral calculi lead to renal colic,the CT ratio of the two kidneys did not determine the size of the stones and the location of the stones, but to a certain extent, the degree of pain could be predicted.
