16层螺旋CT在泌尿系疾病诊断中的应用价值

目的探讨16层螺旋CT在泌尿系疾病诊断中的应用价值。方法115例泌尿系病变病例,60例单纯行16层螺旋平扫,51例行四期扫描(平扫、皮质期、实质期、肾盂期,其中应用Sure-Start软件30例,常规增强21例),非增强尿路成像4例,利用后处理技术对扫描资料进行三维重建处理,可以得到包括肾盏、肾盂、输尿管及膀胱在内的完整尿路成像。结果16层螺旋CT能清晰显示泌尿系统的解剖结构,以及病变和尿路之间的空间关系、双肾功能情况。115例病人中,诊断先天发育畸形17例,胡桃夹现象2例,泌尿系结核10例,多囊肾3例,单纯囊肿10例,泌尿系结石58例,肾、输尿管、膀胱肿瘤15例。结论16层螺旋CT泌尿系扫描,对显示泌尿系病变部位、病因和尿路梗阻的程度及双肾功能,具有检查快速、后处理快捷、安全可靠的特点,可提供完整尿路图像,为临床的准确诊断提供依据。

The application value of 16-slices Spiral CT in the diagnosis of urological system disease

Objective To detect the diagnostic value of 16-slices Spiral CT in the diseases of urological system. Methods 115 cases with urological system disease were performed CT scanning by 16-slices Spiral CT. There are 60 cases were performed only for 16-slices plain spiral scan and 51 cases for 4-phases scan (palin scan, cortex phase, parenchymal phase and pelvis phase). Within the 51cases, 30 were performed by Sure-Start software and the other 21 cases were performed conventional enhancement scan. Non-enhancement urography is 4 cases. Within the 115 cases, there were 17 cases of congenital malformation, 2 cases of walnut cramp sign, 10 cases of urologic tuberculosis, 3 cases of polycystic kidney, 10 cases of pure kidney cysts, 58 cases of urologic stone and 15 cases of urologic tumor. All the dates were sent to the workstation for 3D post processing and the whole urogram, including therenal calices, renal pelvis, nephric duct and bladder were acquired. Results The 16-slices Spiral CT can display the anatomic structure of the urological system and the renal function, as well as the spatial relation between the pathological changes and the urinary passage. Conclusion 16-slices Spiral CT can display the location of the urological system diseases and diagnose their characters and evaluate the degree of the urinary obstruction and renal function. It can also provide the whole urogram. Therefore, it can supply more detailed and accurate evidence for the clinic.
