ABSTRACT
<p><b>OBJECTIVE</b>To analyze and evaluate the characteristics of benign prostatic hyperplasia (BPH) on contrast-enhanced ultrasound.</p><p><b>METHODS</b>Forty-eight BPH patients confirmed by transrectal ultrasound-guided biopsy underwent contrast-enhanced ultrasound. Contrast pulse sequencing technique (CPS) and quantitative software-ACQ were used, and the parameters of beginning enhancement time, disappearing and transit time and peak intensity (PI) of the inner gland and outer gland were recorded and analyzed.</p><p><b>RESULTS</b>The prostate was rich with blood and enhanced significantly on contrast-enhanced ultrasound. The beginning enhancement time of the prostatic inner gland, especially the area around the urethra, was much earlier than that of the outer gland, (26.68 +/- 3.76) and (31.24 +/- 5.33) s, respectively (P = 0.000). The contrast disappeared later in the inner gland than in the outer gland, (200.68 +/- 59.40) and (157.56 +/- 50.66) s, respectively (P = 0.000). The transit time of the contrast in the inner gland was much longer than in the outer gland, (173.94 +/- 60.14) and (129.21 +/- 56.91) s, respectively (P = 0.000). PI of the inner gland was much higher than that of the outer gland, (90.45 +/- 42.19) and (65.32 +/- 25.15) dB, respectively (P = 0.000).</p><p><b>CONCLUSION</b>Contrast-enhanced ultrasound makes it possible to continuously observe the blood perfusion process of BPH, and promises to be an effective means for observing the blood supply in BPH.</p>
