We surveyed the growing literature on ejaculatory duct obstruction and provide suggestions regarding its diagnosis and management.
Ejaculatory duct obstruction is a rare cause of male infertility. With the advent of the high resolution transurethral ultrasound (TRUS) technology, there has been an increase in diagnosis of this disorder. As for the treatment, it appears that central cystic lesions and partial obstructions respond best to transurethral resection of the ejaculatory ducts (TURED).
Ejaculatory duct obstruction is a rare but surgically correctable cause of male infertility. Although there are no pathognomonic findings associated with ejaculatory duct obstruction, the diagnosis should be suspected in an infertile male with oligospermia or azoospermia with low ejaculate volume, normal secondary sex characteristics, testes, and hormonal profile, and dilated seminal vesicles, midline cyst, or calcifications on TRUS. In select cases, TURED has resulted in marked improvement in semen parameters, and pregnancies have been achieved. More studies are needed in the areas of diagnosis and long-term surgical outcome.
我们调查了关于射精管梗阻的不断增多的文献，并就其诊断和管理提供建议。
射精管梗阻是男性不育的罕见原因。随着高分辨率经尿道超声（TRUS）技术的出现，这种疾病的诊断有所增加。至于治疗，似乎中央囊性病变和部分梗阻对经尿道射精管切除术（TURED）反应最佳。
射精管梗阻是男性不育的一种罕见但可通过手术纠正的原因。虽然没有与射精管梗阻相关的特征性表现，但对于精液量少或无精子症、射精量低、第二性征正常、睾丸和激素水平正常，且经TRUS检查发现精囊扩张、中线囊肿或钙化的不育男性，应怀疑有射精管梗阻。在某些病例中，TURED已使精液参数有显著改善，并已实现妊娠。在诊断和长期手术结果方面还需要更多的研究。
