The effect of varicocelectomy on semen parameters of varicocele with low-grade reflux and low testicular vein diameter is poorly documented. Our study aimed at determining whether preoperative venous diameter and grade of reflux predict semen parameters improvement after varicocelectomy.
We studied 85 patients undergoing bilateral laparoscopic varicocelectomy (BLV). Follow-up was performed at 3 and 6 months after surgery. We surveyed the correlation between semen parameters improvement and testicular vein diameter at the inferior pole of the testis, and the degree of reflux measured by color Doppler ultrasound (CDU).
BLV resulted in a statistically significant increase in semen analysis parameters (p = 0.00). There was a correlation between testicular vein diameter and the improvement index in sperm motility (r = 0.31, p = 0.006). There was a significant correlation between the degree of reflux detected by CDU and improvement index in sperm concentration (r = 0.37, p = 0.001).
Patients with testicular vein diameter >2.5 mm and higher grades of reflux detected at the veins at the lower pole of the testis had higher improvement index after BLV. Therefore, we can select the patients with these criteria for BLV.
精索静脉曲张伴有低反流和低睾丸静脉直径的精液参数的精索静脉结扎术效果记录不佳。我们的研究旨在确定术前静脉直径和反流程度是否可以预测精索静脉结扎术后精液参数的改善。
我们研究了 85 例接受双侧腹腔镜精索静脉结扎术(BLV)的患者。术后 3 个月和 6 个月进行随访。我们调查了睾丸静脉下极彩色多普勒超声(CDU)测量的静脉直径和反流程度与精液参数改善之间的相关性。
BLV 导致精液分析参数的统计学显著增加(p = 0.00)。睾丸静脉直径与精子活力改善指数呈正相关(r = 0.31,p = 0.006)。CDU 检测到的反流程度与精子浓度改善指数呈显著正相关(r = 0.37,p = 0.001)。
在睾丸静脉下极静脉检测到睾丸静脉直径>2.5 毫米和较高反流程度的患者,BLV 后改善指数更高。因此,我们可以选择这些标准的患者进行 BLV。
