经直肠超声引导穿刺活检研究前列腺外腺增生

目的 通过经直肠超声(TRUS)引导下的前列腺定点穿刺活检以探讨前列腺外腺是否存在增生。方法 27例患者因临床疑诊前列腺癌而行TRUS引导下前列腺外腺定点穿刺活检，共计47点。同一穿刺点上分别在纵向和横向引导下各穿刺1针；如果外腺有低回声结节，则对该结节穿刺2针。在双盲情况下进行病理诊断。结果 20例患者的前列腺内腺呈对称性增大；9例外腺受压变薄，18例受压征象不明显；3例外腺见低回声结节。47点前列腺穿刺活检均确诊为良性前列腺增生。结论 由于前列腺外腺属于腺性组织，因此，像内腺一样可以出现组织学上的增生。

Hyperplasia of prostatic outer gland studied with transcrectal ultrasound guided biopsies

ObjectiveThe possibility of the hyperplasi a of prostatic outer gland was studied with transrectal ultrasound (TRUS) guided biopsies. MethodsTwenty-seven prostatic outer glands in patients suspicious for prostatic cancer (PCA) were biopsied by TRUS guided, the total sites were 47. The same site was biopsied in sagittal and longitudinal section respectively. The hypoechoic lesion was biopsied 2 times if it was discovered in the outer gland. The histological results were diagnosed in double blind. Results Twenty prostatic inner glands looked symmetrical hyperplasia; 9 outer glands became thin because of the compression, there was no compressive sign in 18 patients; there was a hypoechoic lesion in outer gland of 3 patients. Benign prostatic hyperplasia was diagnosed in the specimens of 47 sites. ConclusionsThe hyperplasia of prostatic outer gland can occur like inner gland because it is glandular tissue.
