    "abstract": "Transurethral resection of ejaculatory duct (TURED) is a primary surgical approach to treat ejaculatory duct obstruction (EDO) caused by the ejaculatory duct cyst. Intraoperative excision of the verumontanum is usually required to expose the ejaculatory ducts. However, preserving the verumontanum structure allows for a better simulation of normal physiological anatomy. Maintaining the verumontanum may increase the risk of postoperative distal ejaculatory duct scarring, leading to recurrent obstruction or reduced semen volume. Therefore, we attempted a novel technique that preserves the verumontanum, which is relatively easier and safer compared to TURED. The following were the procedural steps: 1. A 6F seminal vesiculoscope was introduced through the external urethral orifice to the vicinity of the verumontanum, locating the opening of the affected-side ejaculatory duct and introducing a guidewire into the cyst. This successful step preserved the verumontanum, maximizing the retention of the anti-reflux mechanism in the distal ejaculatory duct. 2. The holmium laser enlarged the affected-side ejaculatory duct opening to 5 mm, decreasing the likelihood of postoperative closure of the ejaculatory duct opening and simplifying the procedure. 3. A window was created within the cyst to access the contralateral seminal vesicle, and then a holmium laser was used to burn and dilate the opening to 5 mm, redirecting the contralateral ejaculatory duct into the cystic cavity. This modification preserved the opening of the healthy-side ejaculatory duct and provided a new outflow passage for semen, reducing the risk of decreased semen volume postoperatively. The patients experienced no complications postoperatively, had shorter hospital stays, and showed improvement in semen volume. Hence, this surgical approach is simple yet effective.",
