[Three-dimentional echography in diagnosis and staging of urinary bladder cancer]
Abstract:
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.
