目的探讨16层螺旋CT尿路造影(CTU)在原发性泌尿道移行细胞癌诊断中的价值.方法回顾性分析26例原发性泌尿道移行细胞癌的CTU征象与术后手术病理比照.其中输尿管癌8例,肾盂癌10例,膀胱癌8例.所有病例均采用5mm层厚、5mm层间距行泌尿道CT平扫,增强扫描(肾皮质期、肾实质期、排泄期),排泄期图像经1mm层厚、0.5mm层间隔重建,进行图像重组.结果26例CTU均得到满意图像,均能清晰显示尿路肿瘤的大小、形态、范围和与其周围组织结构的关系,与术后病理对照符合率100%.结论16排螺旋CTU具有扫描速度快、憋气时间短、侵袭性小的特点,同时可多平面,多方位、立体地显示尿路病变,值得临床推广.
Objective To investigate the value of 16-slice spiral CT urography (CTU) in the diagnosis of primary urinary tract transitional cell carcinoma.Methods The CTU signs of 26 cases with primary urinary tract transitional cell carcinoma were retrospectively analyzed. Including ureteral carcinoma in 8 cases, renal pelvis carcinoma in 10 cases, bladder cancer in 8. All cases were 5mm thickness, 5mm interval urinary tract CT scan, enhanced scan (renal cortex, renal parenchyma, excretion), excretion The images were reconstructed by layer thickness of 1mm and interval of 0.5mm.Results Twenty-six CTUs were satisfactorily imaged, showing clearly the relationship between urinary tract tumor size, shape, extent and its surrounding tissue structure, and postoperative The coincidence rate of pathological control was 100% .Conclusion 16-slice spiral CTU has the advantages of fast scanning speed, short breath holding time and small invasiveness, and can display urinary tract diseases in multi-plane, multi-orientation and stereoscopic manner, which is worthy of clinical promotion.
