目的初步评价双侧精索内动静脉结扎术后睾丸体积及精液质量的变化。方法对34例双侧精索静脉曲张患者中的16例行双侧精索内动静脉结扎术,于术前及术后随访时彩超测量睾丸体积,并行精液常规检查。结果睾丸体积无明显变化(P>0.05);精液量、精子数、精子活率明显提高(P<0.01),精子畸形率明显下降(P<0.01)。结论双侧精索内动静脉结扎术后睾丸无萎缩,精液质量明显改善。 Objective To evaluate the changes of testis volume and sperm quality after arteriovenous ligation in bilateral spermatic cord. Methods Twenty-four patients with bilateral varicocele underwent bilateral spermatic vein ligation. The testis volume was measured by color Doppler ultrasonography at preoperative and postoperative follow-up, and routine sperm routine examination was performed. Results There was no significant change in testicular volume (P> 0.05). The amount of semen, sperm count and sperm motility were significantly increased (P <0.01), and the sperm deformity rate was significantly decreased (P <0.01). Conclusion There is no atrophy of testis after bilateral arteriovenous ligation in bilateral spermatic cord, and the quality of semen is significantly improved.
