螺旋CT尿路三维重建在上尿路梗阻性病变中的应用(附33例报告)

目的 探讨螺旋CT尿路三维重建在上尿路梗阻性疾病中的应用价值。方法 对33例上尿路梗阻患者进行螺旋CT薄层扫描和尿路三维重建，必要时行CT血管造影。结果 33例患者均获明确诊断，其中输尿管结石25例，输尿管肿瘤1例，输尿管良性狭窄3例，输尿管先天畸型3例，盆腔肿瘤1例，所有诊断均经手术证实。结论 螺旋CT尿路三维重建具有三维成象，分辨率高，检查时间短，侵袭性少，易于操作等特点，成为诊断上尿路梗阻性病变最有价值的检查方法。

3-dimentional CT reconstruction in the diagnosis of upper urinary tract obstructive diseases(Report of 33 cases)

Objective To study the diagnostic value of 3-dimentional CT reconstruction in upper urinary tract obstructive diseases. Methods 33 patients with upper urinary tract obstructive diseases underwent thin-slice helical CT scan and 3-dimentional reconstruction of the urinary tract as well as 3-dimentional CT angiography when needed. Results All the cases have definitely diagnosed including ureteral calculi in 25, ureteral carcinoma in 1,bengin ureteral stricture in 3,congenital malformation in 3 and pelvic tumor in 1.All the patients underwent surgical intervention and the diagnosis were confirmed.The operative findings were in concord with the helical CT results. Conclusions 3-dimentional CT reconstruction of the urinary tract can provide distinct urinary tract images and helps determining the site and cause of the obstruction. Compared with other methods,the procedure has the advantages of high resolution,rapid imaging and low invasiveness. It might become the most valuabl means of detecting upper urinary tract diseases.
