Although in the last years varicocele has being recognized with increasing frequency in the adolescents, it is still neglected in pediatric age. Recently several epidemiologic studies revealed an increasing incidence of varicocele in patients between 10 and 16 years, as high at the end of puberty as that of the adult male population. Our study has been carried out on 9861 students, aged between 11 and 18 years, in order to evaluate the effective incidence of the varicocele in pediatric and adolescent age and, at the same time, disclose other possible testicular anomalies in so called "normal" boys. Our study showed that the incidence of varicocele is related to sexual maturation and is time-related with a final incidence of 16%. Left testicular hypotrophy is rather common in primary varicocele and is also time and grade related. Cryptorchidism has been found in 2% of the examined students; 0.4% of them have not been yet operated on. We have been able to discover a rather high incidence of retractile testes (4.7%), always associated with testicular hypotrophy. Finally 7.5% of our examined students presented an unilateral testicular hypotrophy (volume less than 30% of the contralateral normal testis) in complete absence of local pathology.
尽管在过去几年中精索静脉曲张在青少年中的诊断频率越来越高，但在儿童期仍被忽视。最近的几项流行病学研究显示，10至16岁患者中精索静脉曲张的发病率不断上升，青春期结束时与成年男性人群的发病率一样高。我们对9861名年龄在11至18岁之间的学生进行了研究，以评估精索静脉曲张在儿童和青少年期的实际发病率，同时揭示所谓“正常”男孩中其他可能的睾丸异常情况。我们的研究表明，精索静脉曲张的发病率与性成熟有关，且与时间相关，最终发病率为16%。左侧睾丸萎缩在原发性精索静脉曲张中相当常见，也与时间和分级有关。在2%的受检学生中发现了隐睾症；其中0.4%尚未接受手术治疗。我们发现回缩性睾丸的发病率相当高（4.7%），且总是与睾丸萎缩相关。最后，在我们的受检学生中，7.5%的人出现单侧睾丸萎缩（体积小于对侧正常睾丸的30%），且完全没有局部病变。
