64排螺旋CT尿路成像的临床应用价值探讨

目的：探讨64排螺旋CT尿路成像的临床应用价值。方法：对临床怀疑泌尿系统病变的52例患者行64排螺旋CT容积扫描及尿路三维重建。结果：52例中输尿管瘘1例，输尿管结石12例，输尿管癌5例，双肾盂2例，肾盂癌5例，膀胱癌2例，其他3例，正常22例。CT图像不仅能清晰地显示输尿管走行、腔内改变、梗阻部位及原因，还可以同时显示管壁及腔外情况。结论：64排螺旋CT可多方位动态观察肾盂、输尿管及膀胱的正常解剖形态及各种病理改变，并从三维立体图像上获得更丰富的诊断信息，是全面立体动态诊断泌尿系统病变较好的影像检查方法。

Evaluation of clinical application of 64-slice spiral CT urography

Objective： To evaluate the clinical application value of 64-slice spiral CT in the diagnosis of urologic diseases. Methods： Fifty-two cases suspected urinary system diseases were examined with 64-slice spiral CT and 3D reconstruction of urinary tract were performed. Results： Among the 52 cases, there were 1 case with ureteral fistula, 12 eases with calculus of ureter, 5 cases with carcinoma of ureter, 2 cases with double renal pelvis, 5 cases with carcinoma of renal pelvis, 2 cases with carcinoma of bladder, 3 cases with other diseases. 3D photograph showed clearly not only ureteral figure, intraluminal changes of ureter, sites and causes of obstruction, but also walls and extraluminal changes of ureter at the same time. Conclusion： Figures and all kinds of pathological changes about pelvis, ureter and bladder could be observed by 64-slice spiral CT. More diagnostic information could be provided by 3D photographs. 64-slice spiral CT is a kind of efficient imaging examination in the diagnosis of urinary system diseases.
