Abstract:
Objective To assess the clinical value of 16-slice spiral CT in the diagnosis of multiple carcinomas in unilateral upper urinary system. Methods The imaging findings of 16-slice spiral CT of 10 patients suffered from multiple carcinomas in the unilateral upper urinary system proven pathologically were analyzed. Results Among 10 cases, 6 cases had multiple carcinomas in the unilateral renal pelvis and ureter and simultaneously involved urinary bladder, 3 cases had the multiple carcinomas in the unilateral renal pelvis and ureter, and 1 case had the multiple carcinomas in the lower and middle ureter and involved urinary bladder. CT images clearly presented the thickened irregular renipelvic and ureteric wall with stenosis and/or mass in the renipelvic and ureteric cavity. The urinary bladders involved by carcinoma were depicted as thickened irregular wall of urinary bladder or the mass in the wall of urinary bladder. The images of curved reconstruction clearly showed the extention of the multiple carcinomas and the changes of the urinary tract involved by the multiple carcinomas. Enlarged retroabdominal lymph nodes were detected in 3 cases simultaneously, and 2 of them were proved metastasis, the imaging findings were absolutely identical to that of the operation and pathological examination. Conclusion Sixteen slice spiral CT can clearly and accurately depict the location and extention of multiple carcinomas in the unilateral upper urinary system.
