摘要

目的：

通过回顾性分析原发性输尿管移行上皮细胞癌（ureter transitional cell carcinoma，UTCC）的超声造影（contrast-enhanced ultrasound，CEUS）表现，探讨CEUS的诊断效能。

方法：

回顾并分析了26例UTCC患者的资料，所有患者均经手术后病理学检查证实。

结果：

常规超声显示了26例肿瘤的位置，位于输尿管上、中及下段分别为9、7和10例；65.38%（17/26）的UTCC在常规超声上可清晰显示边界，30.8%（8/26）的UTCC可探及肿瘤内部血流信号。在CEUS上所有UTCC呈动脉期及静脉期高增强表现，肿瘤边界均清晰显示。病理学检查结果证实，T

期及T

期肿瘤各13例，肿瘤横径、输尿管管壁形态和分界在高低分期组间差异显著（

＜0.05）：即T

期肿瘤横径较小，病变处输尿管管壁形态规则且分界清晰；而T

期肿瘤横径较大，输尿管管壁形态不规则且分界模糊。

结论：

CEUS较常规超声可更清晰地显示UTCC的边界，肿瘤均呈高增强富血供表现，且CEUS有助于肿瘤的分期评估。

Abstract

Objective:

To investigate the diagnostic performance of contrast-enhanced ultrasound (CEUS) in primary ureter transitional cell carcinoma (UTCC) by retrospectively analysis.

Methods:

Retrospective study was performed on 26 patients with UTCC

and all the cases were confirmed by pathological dignosis after surgery.

Results:

Conventional ultrasound showed the location of

26 tumors

including 9 tumors on the upper part

7 tumors on the middle part and 10 tumors on the lower part. 65.38% (17/26) of the lesion showed clear boundaries on conventional ultrasound

and 30.8% (8/26) detected blood flow signals in the lesion. On CEUS

all UTCC showed hyper-enhancement in arterial phase

and all the tumor boundary was clearly displayed. Pathological results confirmed that there were 13 cases of T

-T

stage and T

-T

stage respectively. The shape and boundary of ureteric wall at the lesion site and the width of the tumor were significant differences between high and low stage groups (

＜0.05). The width of the tumor in T

-T

stage was small

and the ureteral wall was regular and clearly demarcated

while width of the tumor in T

-T

stage was large

and ureteral wall at the lesion site was irregular and blurred.

Conclusion:

CEUS showed UTCC more clearly than conventional ultrasound

and all tumors showed as solid and hyper-enhancement lesions in ureteral lumen. Moreover

CEUS was helpful in evaluating tumor staging.
