摘要
目的探讨64层螺旋cT尿路成像技术（CTU）对泌尿系统疾病的诊断价值。比较CT尿路成像技术和静脉肾盂造影（IVP）检查诊断泌尿系统疾病的准确率。方法总结2年来泌尿系疾病患者217例完整的临床资料，其中输尿管和肾结石87例，输尿管和肾盂肿瘤66例，膀胱肿瘤35例，肾盂源性囊肿和肾盂旁囊肿13例，肾盂输尿管连接处畸形9例，双侧巨输尿管症7例。全部进行64层螺旋CT尿路成像检查，对影像学资料进行回顾性分析。结果217例患者中CTU和IVP检查诊断准确率分别为98．2％（213／217）、65．4％（142／217）。CTU、IVP检查所用时间分别为（19．1±2．9）、（65．3±24．8）min，两者比较差异有统计学意义（P〈0．05）。结论CTU可多角度观察病变局部情况，且扫描时间更短，图像分辨率更高。此检查在诊断泌尿系统疾病准确率、了解病变周围组织情况以及对梗阻远端尿路显示率方面明显优于IVP，可应用于绝大多数的泌尿系统疾病患者中。
Objective To investigate the diagnostic value of 64-slice spiral CT urography（CTU） on patients with diseases of urinary system, and compare the diagnostic accuracy of computed tomography urography （CTU） and conventional intravenous pyelography （IVP） in diagnosis of urologic disease. Meth- ods Two hundred and seventeen patients with urinary tract diseases who presented complete clinical data over the past 2 years were reviewed. There were 87 cases of ureterolithiasis and nephrolithiasis, 66 cases of cancer in ureter and pelvis, 35 cases of cancer in bladder, 13 cases of parapelvic cyst and pyelogenic cyst, 9 cases of ureteropelvic junction obstruction（ UPJO）, 7 cases of megaloureter. All of the cases un- derwent 64-slice CT urography, and the images were analyzed retrospectively. Results The accuracy of diagnosis was 98.2% （213/217） in CTU group and 65.4% （ 142/217 ） in IVP group. The examination time was （19. 1±2.9）min in CTU group and（65.3 ± 24. 8）rain in IVU group. There were significant differences between the two groups （P 〈0.05）. Conclusions 64-slice CT urography can observe the local lesion in multi-angle, and the scan time is shorter, image resolution is higher. The CTU can provide more information than conventional IVP. It could be applied in the vast majority of patients with urinary system diseases.
