先天性双侧射精管缺如伴精囊囊肿1例并文献复习

Congenital bilateral ejaculatory duct absence complicated with seminal vesicle cyst:A case report and review of the literature

目的:报告1例单纯先天性双侧射精管缺如(EDA)伴精囊囊肿的病例,并复习相关文献,提高对本病的诊治水平。方法:通过对1例先天性双侧EDA伴精囊囊肿诊断、治疗的回顾,结合国内外文献报道,综合分析先天性EDA的发生、诊断及治疗。结果:本例经精道造影等检查证实为双侧单纯先天性EDA,合并精囊囊肿,睾丸生精功能正常。结论:先天性EDA源于胚胎期中肾管发育缺陷,精道造影可确诊。双侧EDA患者可行经尿道射精管切开或附睾或睾丸取精行卵细胞胞质内单精子注射治疗。

Objective ： To report a case of simple congenital bilateral ejaculatory duct absence （EDA） complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease. Methods ： We retrospec- tively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant lite- rature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA. Results ： The patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal sper- matogenic function of the testes. Conclusion ： Congenital EDA originates from embryonic developmental defect of the mesonephrie duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.
