%X Uni- or bilateral ejaculatory duct obstruction (EDO) is a rare but correctable cause of infertility, chronic pelvic pain and postejaculatory pain. EDO is a congenital or acquired condition, it is the underlying cause of infertility in approximately 5% of infertile men. If acquired, the etiology often remains unresolved, but prostatitis or urethritis with post-inflammatory adhesion of the duct walls seems to be a common underlying pathomechanism.Although a certain constellation of physicochemical semen parameters may lead to correct diagnosis, EDO often resembles a diagnosis by exclusion. Imaging of acquired EDO remains a challenge and the established surgical therapy, transurethral resection of the ejaculatory ducts (TURED), leads to a low rate of natural conception and a high rate of complications such as reflux of urine and epididymitis. We present a case of a male with suspected EDO who underwent a combined approach to both, semi-invasive diagnosis and therapy by transrectal puncture of the seminal vesicles and antegrade balloon-dilation of the ejaculatory ducts. Possibilities and pitfalls of this procedure are described and the literature is reviewed.Furthermore, we suggest a CT- or MRI-guided, percutaneous intervention for treatment of ejaculatory duct obstruction by balloon dilation and demonstrate initial steps of this procedure with a body donor. We call this new procedure PTED (percutaneous transgluteal ejaculatory ductoplasty).
