Abstract

OBJECTIVES

We determined the effect of varicocele repair on testicular volume according to scrotal ultrasonography, reported to provide the best approximation of actual testicular volume.

METHODS

Forty-four men with left varicocele (mean age +/- standard deviation, 33.4 +/- 5.4 years) underwent varicocele repair. We performed both scrotal ultrasonography with color Doppler imaging and semen analysis before and after varicocele repair. Among these patients, 19 had a clinical left varicocele, 22 had clinical left and subclinical right varicoceles, and 3 had clinical left and right varicoceles. We calculated testicular volumes using the formula: Length x Width x Height x 0.71.

RESULTS

For all 44 patients, mean left and total testicular volume improved significantly after varicocele repair (increases of 1.5 and 2.4 mL, respectively) as did semen profile data such as sperm per unit volume and percentage of motile sperm. In the 19 men with a clinical left varicocele, mean left testicular volume increased significantly (by 1.5 mL) after left varicocele repair, in association with increases in sperm per unit volume and motility percentage. In the 25 men with clinical left varicocele plus a subclinical or clinical right varicocele, mean left and total testicular volume improved significantly after repair of right and left varicoceles (increases of 1.5 and 2.7 mL, respectively). However, right testicular volume showed no significant increase in any patient group.

CONCLUSIONS

Varicocele repair in adults with a clinical left varicocele increased left testicular volume and improved semen profiles.

摘要

目的

我们根据阴囊超声检查确定精索静脉曲张修复术对睾丸体积的影响，据报道阴囊超声检查能最准确地估算实际睾丸体积。

方法

44例左侧精索静脉曲张患者（平均年龄±标准差，33.4±5.4岁）接受了精索静脉曲张修复术。我们在精索静脉曲张修复术前、后均进行了彩色多普勒成像阴囊超声检查和精液分析。在这些患者中，19例有临床左侧精索静脉曲张，22例有临床左侧和亚临床右侧精索静脉曲张，3例有临床左侧和右侧精索静脉曲张。我们使用公式：长度×宽度×高度×0.71计算睾丸体积。

结果

对所有44例患者而言，精索静脉曲张修复术后，左侧睾丸平均体积和双侧睾丸总体积均显著增加（分别增加1.5 mL和2.4 mL），精液指标数据如每单位体积精子数和活动精子百分比也有所改善。在19例有临床左侧精索静脉曲张的男性中，左侧精索静脉曲张修复术后，左侧睾丸平均体积显著增加（增加1.5 mL），同时每单位体积精子数和活动百分比也增加。在25例有临床左侧精索静脉曲张加亚临床或临床右侧精索静脉曲张的男性中，双侧精索静脉曲张修复术后，左侧睾丸平均体积和双侧睾丸总体积均显著增加（分别增加1.5 mL和2.7 mL）。然而，在任何患者组中，右侧睾丸体积均未显著增加。
