Ejaculatory duct obstruction after transurethral resection of the prostate.

Transurethral resection of the prostate is currently the most commonly employed surgical procedure for benign prostatic hyperplasia. Although several complications after the procedure have been well documented, ejaculatory duct obstruction is a rare complication. We describe this unusual complication in a 77-year-old male who presented with severe pain and a feeling of fullness in the lower abdomen and with dry ejaculate on three occasions after undergoing post-transurethral resection of the prostate. The patient's post-ejaculatory urinalysis demonstrated no sperm. Transrectal ultrasonography also showed no dilatation of the bilateral seminal vesicles or ejaculatory ducts. However, ejaculatory duct obstruction was finally diagnosed on vasovesiculography. The patient was successfully treated with transurethral resection of the ejaculatory duct and remained asymptomatic 6 months postoperatively. Although transrectal ultrasonography is currently widely used to evaluate ejaculatory duct obstruction, we suggest that vasovesiculography is still a feasible and useful tool that provides detailed anatomic information for the advanced confirmation of ejaculatory duct obstruction in patients with a high suspicion of ejaculatory duct obstruction who have normal transrectal ultrasonography findings.
