摘　　要：目的:探讨前列腺增生(BPH)经直肠B超检查的图像特征及其对治疗的指导作用。方法:回顾性分析103例经术后病理组织学诊断确诊的BPH患者临床资料,总结其经直肠B超图像特征,并根据B超诊断结果选择适宜治疗方法。结果:经直肠B超检出BHP 98例,2例误诊,3例漏诊,诊断符合率、误诊率、漏诊率分别为95.14%、1.94%、2.91%;B超图像显示BPH病灶呈细小均匀光点,前列腺变圆、增大,内腺以低回声为主,外腺以低回声及中、低混合回声为主;包膜清晰占62.92%;98例确诊为BPH的患者当中,66例行经尿道电切术、16例在B超引导下行无水乙醇注射,16例行开放性手术。结论:直肠B超通过观察回声、内外腺前后径比例、有无包膜、分界情况等准确诊断前列腺增生,同时可通过测量前列腺重量指导临床治疗。Objective： To summarize image features of transrectal B-type ultrasound in the diagnosis of benign prostatic hyperplasia（BPH） and their guiding role in surgery. Methods： We retrospectively analyzed the clinical data of 103 BPH patients confirmed by histopathological diagnosis, summarized the transrectal B-ultrasound features, and chose appropriate treatments on the base of B-ultrasound results. Results： According to the transrectal B-ultrasound, 98 cases had BHP, 2 cases were misdiagnosed and 3 cases were missed.The diagnose accordance rate, misdiagnosis rate and the missed diagnosis rate was respectively 95.74%, 1.94% and 2.91%. B-ultrasound images displayed that BPH lesions appeared as fine light points, and the prostate gland became round and enlarged. Inner gland mainly had hypoechoic while outer gland had iso-echoic, or hypoechoic mixed. Clear envelope accounted for 62.92%. Among the 98 cases confirmed as BPH, 66 cases had transurethral resection, 16 cases got B ultrasound-guided injection of ethanol, 16 cases had open surgery.Conclusion： The transrectal B-type ultrasound can help accurate diagnosis of benign prostatic hyperplasia by observing the echo, the proportion of the anteroposterior diameter of the inner and outer gland, with or without the envelope, boundary conditions and so on. It also can guide clinical treatment by measuring prostate weight.
