To report our experience in the diagnosis, minimally invasive treatment, and composition of seminal vesicle calculi (SVC).
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.
All operations were completed successfully without surgical complications. SVC were mostly composed of hydroxyapatite and protein, suggesting that they were produced by infections.
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.
报告我们在诊断、微创治疗和精囊结石（SVC）成分方面的经验。
本研究评估了 2013 年 1 月至 2018 年 1 月期间我院收治的 20 例患者。所有患者均诊断为难治性血精和 SVC。通过精囊镜进一步确诊。采用篮式提取法取出 SVC；对于较大的 SVC，在提取前用钬激光将其打碎。采用扫描电子显微镜、X 射线衍射和红外光谱分析确定 SVC 成分。
所有手术均顺利完成，无手术并发症。SVC 主要由羟基磷灰石和蛋白质组成，提示其由感染引起。
精囊镜是一种简单、微创的技术，可用于诊断和治疗伴有 SVC 的精囊炎。本研究提高了我们对 SVC 的认识，并为预防 SVC 术后复发提供了理论依据。
