[Ectopic opening of the ejaculatory duct into the urethra: A case report and literature review].

OBJECTIVE

To explore the diagnosis and treatment of ectopic seminal duct opening into the urethra.

METHODS

We reviewed the literature and retrospectively analyzed the clinical data on a case of sex development abnormality. The patient was a 16-year-old gender female seeking medical improvement of female signs, admitted to hospital with "clitoris hypertrophy, no menstruation and chromosome karyotype 46XY", treated by bilateral orchiectomy, and simultaneously examined by seminal vesiculography and cystoscopy.

RESULTS

Seminal vesiculography showed the ectopic opening of the right ejaculatory duct into the urethra accompanied by dysplasia of the seminal vesicle. Cystoscopy exhibited a fissrure-like opening in the right wall of the urethra but no verumontanum. Postoperative pathology revealed bilateral undeveloped testes and epididymides.

CONCLUSION

Ectopic opening of the seminal duct into the urethra is extremely rare and often complicated by many malformations, for the diagnosis of which the most reliable options are seminal vesiculography and retrograde radiography through the ectopic orifice under the cystoscope. The treatment of the disease should follow the principles of timeliness, individualization and consideration of associated malformations.
