Objective:
To study the etiopathogenesis and management of seminal vesicle enlargement.
Methods:
Forty-six cases of seminal vesicle were selected, of which 36 were vesiculitis, treated by antibiotics through a catheter indwelt in the seminal vesicle for 1 week, 3 were cystic vesicular seminalis, given anti-inflammatory treatment by catheter administration and hydatid fluid inhalation, 1 was calculus at the orifice of the ejaculatory duct, taken out by transurethral resection of the verumontanum, 1 was polypous at the orifice of the verumontanum, removed by transurethral resection, 2 were posterior urethritis, treated by fulguration, and 3 were prostatic carcinoma, treated by radical prostatectomy and spermatocystotomy.
Results:
Hemospermia disappeared in 32 cases of vesiculitis during the 6-24 months follow-up, 4 cases experienced recurrent hemospermia 3 months after the treatment. No recurrence was observed in any other case of cystic vesicular seminalis, calculus, polypous, posterior urethritis and prostatic carcinoma.
Conclusion:
Seminal vesicle enlargement has intricate etiopathogenesis, but can be treated with satisfactory results if managed properly.
