目的:探讨经直肠超声(transrectal ultrasonography, TRUS)及CT对输尿管下段病变的诊断价值。方法:分析83例经手术和病理证实的输尿管下段病变患者病例资料,所有患者均行TRUS检查,68例患者接受CT检查。结果:输尿管结石34例,TRUS、CT的结石检出率分别为97.06%(33/34)、95.83%(23/24),P=0.801;输尿管良性狭窄10例,TRUS及CT的诊断符合率分别为80.00%(8/10)及66.67%(4/6);输尿管癌25例,TRUS及CT的诊断符合率分别为92.00%(23/25)及79.17%(19/24),P=0.255;输尿管周围病变致输尿管狭窄或侵犯14例,TRUS及CT的定位诊断符合率分别为92.86%(13/14)及64.29%(9/14),P=0.065;TRUS及CT定性诊断符合率分别为85.71%(12/14)及71.43%(10/14),P=0.357。3例患者TRUS诊断不正确,但CT诊断正确;10例患者CT诊断不正确,但TRUS诊断正确。结论:TRUS及CT对输尿管下段病变均有较高的诊断价值,诊断效果相当,二者各有优势,可相互补充。 |

Abstract: |
Objective:To investigate the value of transrectal ultrasonography (TRUS) and CT in the diagnosis of distal ureteral diseases. Methods:The data of 83 cases of distal ureteral diseases proved by pathology or surgery were analyzed. All patients were examined by TRUS and 68 by CT. Results:For distal ureteral calculi (34 cases), the detection rates by TRUS and CT were 97.06% (33/34) and 95.83% (23/24) respectively (P=0.801). For benign distal ureteral stricture (n=10), the diagnostic accuracy rates of TRUS and CT were 80.00% (8/10) and 66.67% (4/6), respectively. For ureteral cancer (25 cases), the diagnostic accuracy rates of TRUS and CT were 92.00% (23/25) and 79.17% (19/24), respectively (P=0.255). For ureteral stricture or infiltration caused by periureteral lesions (14 cases), the localization diagnostic accuracy rates of TRUS and CT were 92.86% (13/14) and 64.29% (9/14), respectively (P=0.065), and the qualitative diagnostic accuracy rates of TRUS and CT were 85.71% (12/14) and 71.43% (10/14), respectively (P=0.357). In 3 cases,the diagnosis of TRUS was inaccurate but that of CT was accurate. In 10 cases, the diagnosis of CT was inaccurate but that of TRUS was accurate. Conclusions:TRUS and CT show similar high value in the diagnosis of distal ureteral diseases. Both have their own advantages and can complement each other. |
