| 目的 探讨膀胱内翻性乳头状瘤与膀胱移行细胞癌的声像表现异同点。方法 回顾性分析55例膀胱内翻性乳头状瘤与100例膀胱移行细胞癌患者的术前超声检查资料,比较两组患者的年龄,病灶位置、最大径、形态、边缘、内部回声,病灶的纵径与最大横径比值(L/T)、基底宽径与最大横径比值(B/T)及血流分布情况。结果 膀胱内翻性乳头状瘤与膀胱移行细胞癌病灶形态均较规则,边缘相对光整或稍毛糙,内部回声较均匀。膀胱内翻性乳头状瘤病灶多位于膀胱三角区及周围(43/54,79.63%),高于膀胱移行细胞癌的43.59%(51/117,χ2=19.388,P<0.05),患者年龄[(56.0±14.7)岁 vs (63.1±14.5)岁,t=2.759,P<0.01]、病灶B/T比值[0.84±0.21 vs 0.94±0.15,t=-3.452,P<0.01]小于膀胱移行细胞癌,而L/T 大于膀胱移行细胞癌,病灶多呈高回声(42/54,77.78%),乏血供。38例膀胱内翻性乳头状瘤术前超声检查误诊为膀胱癌。结论 膀胱病灶部位、形态、回声、血流是超声鉴别诊断膀胱内翻性乳头状瘤与膀胱移行细胞癌的主要声像学表现。 |

| To explore the ultrasonic features of inverted papilloma of bladder (IPB) and transitional cell carcinoma of bladder (TCCB). Methods Totally 55 patients with IPB (IPB group) and 100 patients with TCCB (TCCB group) were collected, and the data of patient age, lesion location, size, shape, margin, internal echo, longitudinal/transverse diameter ratio (L/T), basal width/transverse diameter ratio (B/T) and blood flow were retrospectively analyzed. Results Most lesions of IPB and TCCB showed regular shape, smooth margin and homogeneous echo, 79.63% (43/54) IPB lesions located in bladder trigone and the surrounding, higher than that of TCCB lesions (43.59% [51/117], χ2=19.388, P<0.05), displayed high-level echo and little blood flow. The patient age [56.0±14.7 vs 63.1±14.5, t=2.759, P<0.01] and the B/T ratio [0.84±0.21 vs 0.94±0.15, t=-3.452, P<0.01] in IPB group were smaller than that in TCCB group, while L/T ratio [1.23±0.57 vs 0.74±0.20, t=13.018, P<0.01] in IPB group were greater than that in TCCB group. Thirty-eight cases of IPB were misdiagnosed as bladder cancer by preoperative ultrasonography. Conclusion The lesion location, shape, echo and blood flow are the main ultrasonic features for differential diagnosis between IPB and TCCB. |
