OBJECTIVE
The purpose of this investigation was to study the correlation between hypoechoic nodules detected on ultrasonography and benign hyperplasia in the prostatic outer gland (POG) diagnosed by transrectal ultrasonography (TRUS)-guided biopsies.
METHODS
The TRUS-guided biopsies were performed on 472 patients suspected of having prostate cancer. Specimens obtained by biopsies were independently assessed by pathologists at 3 hospitals.
RESULTS
The histologic results of 310 patients (65.68%) were benign. Focal hypoechoic nodules located in the POG were found in 240 patients (50.8%) on TRUS scans. Among them, in 22 patients (9.17% of the 240 patients with hypoechoic nodules), benign hyperplasia was found in focal hypoechoic nodules located in the POG. Focal nodules were seen as well circumscribed with an ovoid shape and smooth surface in 18 patients.
CONCLUSIONS
Benign hyperplasia may sometimes originate in the POG and may appear as a hypoechoic nodule, similar to the appearance of prostate cancer.
目的
本研究旨在探讨经直肠超声（TRUS）引导下活检诊断的前列腺外腺（POG）低回声结节与良性增生之间的相关性。
方法
对472例疑似前列腺癌的患者进行TRUS引导下活检。活检获取的标本由3家医院的病理学家独立评估。
结果
310例患者（65.68%）的组织学结果为良性。TRUS扫描发现240例患者（50.8%）的POG中有局灶性低回声结节。其中，22例患者（占240例有低回声结节患者的9.17%）的POG局灶性低回声结节中发现良性增生。18例患者的局灶性结节边界清晰，呈椭圆形，表面光滑。
结论
良性增生有时可能起源于POG，并可能表现为低回声结节，类似于前列腺癌的表现。
