The role of USI and three-dimentional volumetric reconstruction was studied in diagnosis of urinary bladder cancer diagnosis. 69 UBC patients were examined. Examination included renal USI of the kidneys, urinary bladder, prostate, echoureterography, cystoscopy, CT, MRT. The number of the tumors, volume, area, invasion were studied in 3D mode. US angiography assessed resistance index and tumor vascularization by degrees 0-3. USI findings were compared with those of MRT, cystoscopy, histomorphology of the biopsies. 2D USI technique proved effective in detection of urinary bladder cancer at stage T1 in 66%, 3D in 100. At stage T2a-b informative value of both techniques reached 87%. Overall informative value of 2D in detection of urinary bladder cancer was 81%, three-dimentional echography--96%. USI proved effective in diagnosis and staging of urinary bladder cancer. Use of 3D ultrasonic angiography facilitates the choice of more effective surgical policy in the treatment of urinary bladder cancer patients.
研究了超声成像（USI）和三维容积重建在膀胱癌诊断中的作用。对69例膀胱癌患者进行了检查。检查包括肾脏、膀胱、前列腺的肾脏超声成像、超声输尿管造影、膀胱镜检查、CT、磁共振成像（MRT）。以三维模式研究肿瘤的数量、体积、面积、浸润情况。超声血管造影评估阻力指数和肿瘤血管化程度（0 - 3级）。将超声成像结果与磁共振成像、膀胱镜检查、活检组织形态学结果进行比较。二维超声成像技术在检测T1期膀胱癌时的有效率为66%，三维超声成像为100%。在T2a - b期，两种技术的信息价值均达到87%。二维超声成像在检测膀胱癌中的总体信息价值为81%，三维超声检查为96%。超声成像在膀胱癌的诊断和分期中被证明是有效的。使用三维超声血管造影有助于为膀胱癌患者选择更有效的手术策略。
