精囊囊肿很少见,多数是先天性的,常与同侧肾、输尿管缺失或畸形有关;后天性精囊囊肿常与尿路感染所致射精管梗阻有关。过去,很少诊断精囊囊肿,因为精囊显象困难。精囊造影为有创性检查,可经直肠、经尿道或手术经输精管注射造影剂完成。最近,影象技术的进步大大简化了精囊的显象。CT和超声可以非常清晰地显示膀胱后结构的轮廓,同时可以区分实质性与囊性结构。CT尚可显示邻近结构的解剖关系。虽有先进的影象技术,高度怀疑本病是诊断的前提。精囊囊肿患者多有下尿路及会阴部症状。常见的临床过程是附睾炎和前列腺炎的反复发作。
Seminal vesicle cysts are rare, most are congenital, often with the ipsilateral kidney, ureter missing or deformity; acquired seminal vesicle cyst often associated with urinary tract infection caused by ectopic obstruction. In the past, seminal vesicle cysts were rarely diagnosed because seminal vesicle imaging was difficult. Seminal vesicle angiography invasive examination can be transrectal, transurethral or surgical injection of contrast agent through the vas deferens to complete. Recently, advances in imaging technology have greatly simplified the development of seminal vesicle. CT and ultrasound can clearly show the contour of the posterior bladder structure, while distinguishing between the parenchyma and cystic structures. CT can still display the anatomy of the adjacent structures. Although advanced imaging technology, a high degree of suspicion of the disease is the premise of diagnosis. Seminal vesicle cyst patients have lower urinary tract and perineal symptoms. Common clinical course of epididymitis and prostatitis recurrent.
