The management and composition of symptomatic seminal vesicle calculi: aetiological analysis and current research

摘要

Objective To report our experience in the diagnosis, minimally invasive treatment, and composition of seminal vesicle calculi (SVC). Patients and methods In the present study, we evaluated 20 patients who were admitted to our hospital from January 2013 to January 2018. All the patients were diagnosed with intractable haematospermia and SVC. The diagnosis was further confirmed by seminal vesiculoscopy. SVC were removed by basket extraction; with larger SVC fragmented by holmium laser before extraction. Scanning electron microscopy, X‐ray diffraction, and infrared spectroscopy were used to determine the SVC composition. Results All operations were completed successfully without surgical complications. SVC were mostly composed of hydroxyapatite and protein, suggesting that they were produced by infections. Conclusions Seminal vesiculoscopy is a simple, minimally invasive technique that can be used for diagnostic confirmation and treatment of seminal vesiculitis with SVC. This study improves our understanding of SVC and provides a theoretical basis for the prevention of postoperative recurrence of SVC.
