Abstract:
Objective To observe the characteristics of normal prostate gland and benign prostatic hyperplasia (BPH) on transrectal real-time elastography (TRTE). Methods A total of 77 BPH patients and 17 normal subjects underwent TRTE. The elastographic images were analyzed with the five-point subjective elastic scale. The strain ratio of transition zone, peripheral zone, and transition zone to peripheral zone were respectively measured to compare the stiffness of each zone. Results The elasticity scores of both BPH group and normal prostate group were 1 and 2 in scoring system. There was no significant difference of elasticity scores between BPH group and normal prostate group (P=0.2252), as well as in strain ratio of transition zone (P=0.9793), peripheral zone (P=0.8986), and transition zone to peripheral zone (P=0.5233). Conclusion The stiffness of normal prostate gland and BPH could be offered by TRTE.
