Abstract：Objective To explore the clinical value of transcectal ultrasound in seminal vesiclel diseases.Methods Transcectal ultrasound were studied in 110 seminal vesiclels of 60 cases and ultrasonographys were obtained.Results Seminal vesiclel diseases including acute,chronic seminal vesiculitis,cyst,tuberculosis,calculi and tumormetastases were corrected by puncture,operation,and/or CT scanning.Conclusion Detection of seminal vesiclel with transcectal ultrasound was a simple,safe,acurate method and has an important clinic significance.

为探索精囊腺疾病有效的诊断手段，我们应用经直肠高频超声探头对60例临床怀疑精囊腺疾患的患者进行精囊腺的探查，经最终穿刺、手术和(或)CT扫查证实为急性、慢性炎症、囊肿、结核、结石和转移癌。现报告如下。
1 资料与方法
1.1 一般资料 患者为我院门诊及住院者，60例患者中主诉血精者50例，有血尿者10例，有性功能减退者31例，发热者11例，不育者19例，共110例异常精囊腺进行了经直肠超声多普勒检测。
1.2 方法 应用Sequioa 512型彩色多普勒超声诊断仪，凸弧形经直肠探头，频率7.5 MHz。检查前排空大便并清洗肛门及周围，检查时膀胱内需有少量尿液。患者取左侧卧位，使髋、膝关节半屈曲。将粘有少量耦合剂的探头放入避孕套内，再外涂适量耦合剂，随后将探头缓慢插入肛门，根据需要调节探头的深度与方向。当荧光屏上精囊腺清晰显示时，仔细观察其形态和内部回声以及邻近器官组织的图像测量数据及彩色多普勒频谱。
2 结果
2.1 急性精囊腺炎 精囊腺肿大，内部呈较多小分隔状低回声与不均匀性强回声交错分布，边缘毛糙、模糊，表面迂曲消失。Doppler示血流速度快，血供增多，阻力指数略偏低。
