OBJECTIVES: The purpose of this review is to survey the growing literature on ejaculatory duct obstruction and to provide a comprehensive overview of the current trends in the diagnosis and management of patients with this disorder. MATERIALS AND METHODS: Review of current literature on ejaculatory duct obstruction. RESULTS: Ejaculatory duct obstruction is a surgically treatable cause of male infertility. It is usually suspected in an infertile male who has low ejaculate semen volume but normal testicular size and normal secondary male sexual characteristics. CONCLUSION: Transrectal ultrasonography is the initial investigation method used to visualize and locate the presence of a cyst or calcifications that may contribute to the obstruction. Transurethral resection of the ejaculatory ducts represents the best treatment modality, resulting in marked improvement in the semen parameters and pregnancy rate in well selected cases.
Magnetic resonance imaging (MRI) offers superb soft tissue contrast on T2-weighted images and allows direct multiplanar image acquisition. It can show the internal prostatic anatomy, prostatic margins, and the extent of prostatic tumors in much more detail than computed tomography (CT) images. The present article reviews some key prostatic and periprostatic radiologic landmarks that can be helpful for the radiotherapist using T2-weighted MRI as an adjunct to CT in treatment planning for prostate cancer.
A 7-month-old patient with a verified urinary tract infection showed an unusual mictiocystography finding of reflux via the right ejaculatory duct into the epididymis. Usually such reflux is associated with anomalies of the genitourinary tract. This case demonstrated that reflux may occur in healthy infants and that it may be clinically associated with urinary tract infections.
