Abstract
Objective
To observe the sonographic and hemodynamic features of hypoechoic hypertrophic lesions and hypoechoic cancer lesions in the hypertrophic prostate inner glands, in order to raise the accuracy of early diagnosis rate for prostate cancer.
Methods
31 cases of hypoechoic hypertrophic lesions and 18 cases of hypoechoic cancer lesions in the hypertrophic prostate inner glands were observed by transrectal ultrasonography and comparatively analyze the shape, edge and the systolic peak velocity (Vs), resistance index (RI) and pulsatility index (PI) of the lesions.
Results
In contrast with hypertrophic group, the cancer group presented irregular shape and unclear edge, and obviously higher Vs, RI and PI.
Conclusion
The sonographic appearance and Vs. RI. PI have important value in distinguishing hypoechoic hypertrophic lesions and hypoechoic cancer lesions in the hypertrophic prostate inner glands.
