目的探讨经直肠超声(TRUS)检查对前列腺癌的诊断价值。方法回顾经直肠超声检查的前列腺癌患者16例,经手术及穿刺取材病理证实,简要归纳经直肠超声下前列腺癌的二维和彩色声像图特征,评价该检查对前列腺癌的价值。结果1.声像图特征:前列腺癌性结节多位于外周区(约86%),病灶较小时多为均匀性低回声或等回声,境界也较清晰,而结节内部血流信号稀疏;癌性结节较大时,可呈多种类型的表现,内部血流丰富,阻力指数较高,平均为0.79。2.16例前列腺癌患者经直肠超声诊断正确13例,诊断符合率81.2%,误诊3例。结论经直肠超声检查前列腺癌的声像图有一定的规律性,可以提高前列腺癌的诊断准确率。
Objective To investigate the diagnostic value of transrectal ultrasound (TRUS) in the diagnosis of prostate cancer. Methods A retrospective study of 16 cases of prostate cancer by transrectal ultrasound was performed. According to the histopathology and histopathology, the two dimensional and color sonographic features of prostate cancer under transrectal ultrasound were summarized to evaluate the value of this test for prostate cancer. Echocardiography Features: Prostate cancerous nodules are mostly located in the peripheral region (about 86%), the lesser lesions are more uniform hypoechoic or equal echo, the state is also more clear, and nodules within the sparse blood flow signal; When the cancerous nodules were large, they showed various types of manifestations, with abundant internal blood flow and high resistance index, with an average of 0.79.2. Among 13 cases of prostate cancer, 13 cases were correctly diagnosed by transrectal ultrasound, the diagnostic coincidence rate was 81.2%, misdiagnosis 3 cases. Conclusion Transrectal ultrasound examination of prostate cancer sonogram has a certain regularity, can improve the diagnostic accuracy of prostate cancer.
