Vesicoscopic procedures generally include both normal approach procedures and open window procedures. There are two routes of entry into the seminal vesicles when performing vesicoscopy. One is through the opening of the ejaculatory duct under normal anatomy into the ejaculatory duct and then into the seminal vesicle. The ejaculatory duct opening is located in the seminal vesicle 2-3 mm adjacent to both sides of the opening of the prostatic vesicle, and the opening of the prostatic vesicle is arranged in a triangular, inverted triangular, or rectilinear relationship. The opening of the ejaculatory duct is very narrow and usually covered with membranous tissue, which makes it difficult to see even under low-pressure saline irrigation. In patients with seminal vesiculitis, it is even more difficult to recognize the opening when it is irritated by inflammation. If it is not possible to find the opening, a second approach is taken, which is to perform a windowing procedure through the prostatic vesicles. The seminal vesicles are usually located lateral and posterior to the cystic cavity of the prostatic vesicles, and the separation between the two is extremely weak, resembling a semi-permeable membrane. The technique for determining this is to use pulsatile low-pressure saline irrigation and observe the movement of the sac wall. The location of the aperture is usually evident where periodic movements of subsidence and expansion driven by pulsatile water flow are present. A 0.038-inch zebra guidewire is used to penetrate the cystic wall or a holmium laser incision is made, and the vesicoscope is then introduced into the seminal vesicle. The vesicoscopy procedure needs to be performed by a specialized urologist, who can be consulted for specific details.
