O 23. Clinical application of transurethral seminal vesiculoscopy for treating stones in seminal tract

Objective: To explore the causes of the stones of seminal tract and the value of transurethral seminal vesiculoscopy (TSV) in treating this disease.

Methods: Totally 22 patients with hematospermia and stones of seminal tract in this study. Patients were aged 25.1± 4.1 years, with a history of hematospermia for 6-24 months. Preoperative ultrasonography, CT, and plain film X-ray examination confirmed the diagnosis of prostate stones in 10 cases, prostatic calcification in 3 cases, seminal vesicle stones in 9 cases. TSV was applied for treating the stones.

Results: After 3-6 months' follow-up, the symptoms of hematospermia disappeared in all patients. Stone remnants were detected in four patients but caused no conscious discomfort. No remarked complication was noted. The ejaculation did not change remarkably. Laboratory analysis showed that there were calcium phosphate stones in 5 cases, calcium carbonate stones in 8 cases, uric acid stones in 4 cases, and mixed stones in 5 cases.

Conclusions: The stones of seminal tract may be related to the changed verumontanum opening direction and the small prostate capsule opening and ejaculatory duct opening. The stone is also a major cause of hemosperimia. TSV provides a promising way to treat this disease.
