Clinically, patients with hematospermia are usually treated with conservative medication, but some patients with severe hematospermia have ineffective conservative treatment. Our department has recently carried out transurethral resection of seminal vesicles with satisfactory results. In order to prevent ureteral injury, a double “J” tube was placed in each ureter, and then the vesicoureteral electrodesection was started. A vertical electrodesiccation ring was used to cut a deep groove, about 1.5 cm long and 2 cm wide, in the direction of the urethra in the 5-7 o’clock area of the bladder neck with the bladder neck opening as the boundary, reaching the whole bladder wall and the prostatic envelope. A horizontal electrosurgical ring is exchanged and the boundary between the prostatic envelope and the bladder wall is identified in this area, and the ring is applied to bluntly separate the boundary so that the bladder wall of the triangle is pushed anteriorly, thus separating a potential gap in the area behind the bladder wall and above the base of the prostate, with a slight separation to the sides to reach the area where the seminal vesicles are located bilaterally. The vas deferens was then retracted to the plane of the seminiferous tubules and a large amount of dark red old bloody fluid was observed at the opening of the vas deferens, so a vertical electrodesiccation ring was taken and an incision was made proximally along this opening to widen the opening of the vas deferens. The opening of the ejaculatory duct was enlarged proximally to the urethra to connect with the above-mentioned sulcus. Both sides of the vesicourethral cavity were seen to have fissure-like openings and a large amount of old bloody fluid was spilled. The lacunar opening of the seminal vesicles on both sides was enlarged separately, and a markedly irregular cystic enlargement of the seminal vesicle cavity, approximately 3×3×5 cm in size, with an uneven yellow-white honeycomb-like inner surface, resembling the inner wall of the bladder with extensive trabecular formation and a large amount of old bloody fluid filling it, was seen, but no neoplastic or active bleeding was observed. The entire inner wall of the seminal vesicle was carefully excised and extensive electrocautery was performed to stop the bleeding, resulting in extensive fresh trauma on the inner surface of the seminal vesicle, and the ejaculatory duct cyst inner wall was extensively cauterized by retracting the mirror, and the procedure was completed after complete hemostasis of the trauma. After the operation, the patient’s hemorrhage disappeared and the treatment result was good.
