We compared the clinical utility of nonenhanced computed tomography (NECT) and intravenous urography (IVU) in patients with classic symptoms of renal colic without evidence of a urine infection. This was a retrospective analysis of IVU and NECT performed in adult patients with suspected renal colic at an emergency department between January 2005 and December 2013. The records of all patients in NECT and IVU groups were reviewed, and the patients were categorized according to the cause of their symptoms. A total of 2218 patients were enrolled. Of these patients, 1525 (68.8%) underwent IVU and 693 (31.2%) underwent NECT. The patients in NECT group were older (45.48 ± 14.96 versus 42.37 ± 13.68 years, p < 0.001), had less gross hematuria (7.6 versus 2.9%, p < 0.001), and were admitted more often (18.6 versus 12.0%, p < 0.001) than the patients in IVU group. Urinary stones were detected in 1413 (63.7%) patients. NECT had a higher detection rate of urolithiasis than IVP (74.0 versus 59.0%, p < 0.001). No significant difference was observed in the incidence of urinary stones greater than 4mm between groups from the radiologic findings (p = 0.79) or the full medical record review (p = 0.87).
我们比较了非增强计算机断层扫描（NECT）和静脉肾盂造影（IVU）在无尿路感染证据的典型肾绞痛患者中的临床应用价值。这是一项对2005年1月至2013年12月期间在急诊科疑似肾绞痛的成年患者进行的IVU和NECT的回顾性分析。对NECT组和IVU组所有患者的记录进行了审查，并根据症状原因对患者进行了分类。共纳入2218例患者。其中，1525例（68.8%）接受了IVU检查，693例（31.2%）接受了NECT检查。NECT组患者年龄较大（45.48±14.96岁对42.37±13.68岁，p<0.001），肉眼血尿较少（7.6%对2.9%，p<0.001），入院率更高（18.6%对12.0%，p<0.001）。1413例（63.7%）患者检测到尿路结石。NECT对尿路结石的检出率高于IVP（74.0%对59.0%，p<0.001）。从影像学检查结果（p=0.79）或完整病历审查（p=0.87）来看，两组之间大于4mm的尿路结石发病率无显著差异。
