Figure 1: Ultrasonic images and endoscopic images of a partial EDO patient. (a–c) Ultrasonic images before vesiculoscopy treatment. (d–f) Endoscopic images during surgery. (g–i) Ultrasonic images 7 months after surgery. (a) Calcification within the ejaculatory duct. (b) Ultrasonographic manifestations of the ejaculatory ducts and prostatic utricle before surgery. The white arrow indicates the calcified ejaculatory duct. The black arrow indicates the dilated prostatic utricle. (c) TRUS showed the process of ejaculation. The black arrow indicates the seminal fluid flowing through the dilated ejaculatory duct during ejaculation. The white arrow indicates the calcification blockage at the distal end of the ejaculatory duct. (d) The calcification within the verumontanum orifice. (e) The verumontanum orifice was cleared after surgery. (f) The seminal vesicles were connected with the prostatic utricle. The white arrow indicates the wall of the prostatic utricle. The black arrow indicates the exposed right seminal vesicle lumen. (g) After surgery, there was less calcification within the ejaculatory duct and adjacent tissues. The black arrow shows the prostatic utricle turned into a potential space. (h) During ejaculation, the prostatic utricle expanded and the seminal fluid flowed into the prostatic utricle. (i) A new ejaculatory channel consisting of the seminal vesicle and prostatic utricle was formed. EDO: ejaculatory duct obstruction.
