Ejaculatory duct obstruction: TRUS-guided opacification of seminal tracts
1Department of Radiology, Seoul National University College of Medicine, Korea.
Objective:
To assess the usefulness of TRUS-guided aspiration and opacification of seminal tracts in the evaluation and management of patients with ejaculatory duct obstruction (EDO).
Methods:
In 21 men who had dilated seminal vesicles and/or midline cysts on TRUS, a mixture of contrast media and indigocarmine was injected and then pelvic radiographs were taken.
Results:
The diagnoses based on the findings of TRUS-guided opacification were bilateral EDO in 9 patients, unilateral EDO in 1, and midline cyst with EDO in 11. Midline cysts had communication with seminal tracts in 7. Transurethral unroofing was performed in 12, in all of whom blue color of the injected indigocarmine facilitated the surgical procedure.
Conclusion:
TRUS-guided opacification of the seminal tracts with a mixture of contrast media and indigocarmine may be valuable in the evaluation and management of the patients with EDO.
