To describe the methodology of transurethral seminal vesiculoscopy and the anatomy of the seminal tract, and to report a single-surgeon experience with this procedure.
A total of 38 consecutive patients with intractable macroscopic hemospermia were enrolled from January 2010 to July 2016. A 6/7.5-Fr semirigid ureteroscope was used to enter the seminal tract by one of these two approaches: through either a trans-ejaculatory duct opening or a trans-utricle fenestration. Patient characteristics and their preoperative and postoperative measurements were analyzed retrospectively.
The success rate of transurethral seminal vesiculoscopy was 92.1%, whereas the approaching method in most patients was the trans-utricle fenestration (88.89%). A total of 34 (94.4%) transurethral seminal vesiculoscopy inspections ended with complete remission, even though nearly half of them (47.2%) only disclosed negative perioperative findings. The median period to complete remission was 4 weeks (interquartile range 4-6 weeks) after the procedure. Four patients had recurrent hemospermia, and the median time to recurrence was 21.5 (range 13-48.5) months.
Transurethral seminal vesiculoscopy is a valuable diagnostic tool for intractable hemospermia, and also plays a therapeutic role by blocking the vicious cycle of stasis, calculi and seminal vesiculitis. More familiarity of the anatomy and enough practice would make the learning curve less steep.
描述经尿道精囊镜检查的方法及精道的解剖结构,并报告单术者开展该手术的经验。
2010年1月至2016年7月共纳入38例连续性顽固性肉眼血精患者。使用6/7.5Fr半硬性输尿管镜通过以下两种方法之一进入精道:经射精管开口或经膀胱颈小孔。对患者特征及其术前和术后测量结果进行回顾性分析。
经尿道精囊镜检查的成功率为92.1%,而大多数患者(88.89%)的进入方法是经膀胱颈小孔。共有34例(94.4%)经尿道精囊镜检查以完全缓解结束,尽管其中近一半(47.2%)仅显示围手术期阴性结果。术后完全缓解的中位时间为4周(四分位间距4 - 6周)。4例患者出现复发性血精,复发的中位时间为21.5(范围13 - 48.5)个月。
经尿道精囊镜检查是顽固性血精的一种有价值的诊断工具,并且通过阻断淤积、结石和精囊炎的恶性循环也发挥治疗作用。对解剖结构更熟悉并进行足够的练习会使学习曲线没那么陡峭。
