【Abstract】Objectives: To explore the impact on semen quality of varicocele patients with spermatic vein ligation under the outer ring microsurgery, and to observe and analyze its security. Methods: 104 varicocele patients were selected in the hospital from October in 2012 to March in 2014 and according to the operation method, were divided into the control group (51 cases) and the observation group (53 cases). The control group was treated by laparoscopic ligation of spermatic vein, while the observation group was treated by microsurgery under the outer ring ligation of spermatic vein. The operation time, blood loss, postoperative hospitalization time of two groups was recorded; the semen quality and malformation rate before and after the treatment was detected; the postoperative complications and recurrence was observed. Results: The blood loss and hospitalization time of the observation group respectively were (24.58±4.93) ml and (5.13±1.24) d, lower than the control group, with statistically significant difference (P 【Key words】Microsurgery; Spermatic vein ligation; Varicocele; Semen quality

精索静脉曲张是精索静脉因多种原因回流受阻、不畅,精索蔓状静脉丛扩张、迂曲、伸长,在阴囊里形成蚯蚓形状的团块,易引起患者睾丸的功能进行性衰退。主要表现为疼痛、阴囊坠胀不适、精液异常、男性不育等。临床治疗以精索静脉结扎手术为主,以有效阻止血液的返流[1,2]。近年来,显微镜外科精索静脉结扎术逐渐得到广泛应用,已成为治疗VC的主要术式。本研究旨在探讨外环下显微外科精索静脉结扎术对精索静脉曲张患者精液质量的影响,并观察和分析其安全性。
1资料与方法
1.1一般资料
随机选择本院2012年10月至2014年3月精索静脉曲张患者104例,纳入病例:均进行阴囊彩超显示精索静脉曲张并伴反流、Valsalva 实验阳性。排除病例:继发性精索静脉曲张患者。入选患者年龄24~49岁,平均(31.75±7.80)岁,根据手术方法分为对照组51例和观察组53例,对照组患者采用腹腔镜下精索静脉结扎术;观察组患者采用外环下显微外科精索静脉结扎术。两组患者年龄、病变部位、程度和病程比较,差异无统计学意义(P>0.05),具有可比性。见表1。
1.2方法和指标
1.2.1治疗方法观察组患者采用外环下显微外科精索静脉结扎术,在股沟外环下阴囊外上方作长约2~3cm 的斜形切口,逐层切开,露出精索、提起后牵出,将睾丸提出切口外,切断结扎扩张的睾丸引带静脉,显微镜下分离精索内外静脉、提睾肌静脉,双重结扎后切断,术中保护睾丸动脉、淋巴管及相关神经。还纳精索,逐层关闭切口。如为双侧病变,采取同样的术式进行处理。对照组患者采用腹腔镜(Olympus 腹腔镜系统)下精索静脉结扎术,距离内环口2~3cm处精索血管外侧,切开后腹膜,游离整束精索血管,分离精索内动、静脉,双重丝线结扎精索静脉并离断[3,4]。本研究经医院伦理委员会批准,患者及家属的同意签署知情同意书。
1.2.2主要指标记录两组患者手术时间、出血量、术后住院天数,术后并发症及6个月后复发状况,检测手术前后精液质量,包括精子密度、精子活力、巴氏染色计数精子畸形率。
1.3统计学处理
用SPSS11.0统计软件。计量资料采用均数±标准差(±s)表示,采用t检验,计数资料比较用χ2检验,P0.05)。见表2。
2.2两组患者治疗前后精液质量结果比较
观察组患者治疗后精子数量、精子活力和精子活动率分别为(43.76±7.22)×106/mL、(48.66±5.93)%和(55.28±7.50)%,均高于对照组治疗后,两组治疗后均高于治疗前,差异具有统计学意义(P参考文献
