Abstract：Objective:To explore the etiological factors for calculus-associated seminal vesiculitis by analyzing the composition of seminal vesicle calculus samples.Methods:This retrospective study included 6 cases of recurrent hematospermia diagnosed with seminal vesicle calculus by non-contrast pelvic CT.The patients were aged 28 to 69 years,with persistent or recurrent hematospermia for 3 months to 6 years,and 5 of them with a history of acute urethritis.All the patients underwent seminal vesiculoscopy,which confinned calculus-associated seminal vesiculitis.The calculus samples were obtained with a spiral dislodge and their composition was determined with a second-generation infrared calculus composition analyzer.The patients were followed up for 2 to 12 weeks postoperatively,during which non-contrast pelvic CT was employed for observation of recurrent calculus in the reproductive tract.Results:Pelvic CT scanning indicated recurrence of seminal vesicle calculus in 3 cases at 12 weeks postoperatively,of which,2 were accompanied with recurrent hematospennia,both observed at 4 weeks after operation.As for the composition of the calculus,the infrared calculus composition analyzer revealed struvite (magnesium ammonium phosphate hexahydrate) in 5 cases and a mixture of calcium oxalate dihydrate,calcium oxalate monohydrate,and carbonate apatite in the other one.Conclusion:Seminal vesicle calculi are most commonly composed of struvite,and infection is the main etiological factor for calculus-associated seminal vesiculitis.
