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.
