隐睾是小儿常见病,因其能影响生育力和可能发生癌变,需要合理治疗。但治疗的适宜年龄及方法选择等问题都值得探讨。现根据本院的临床和实验研究资料结合文献讨论如下。一、治疗的最适年龄有人调查3,612名男婴,97.3%足月儿和79%未成熟儿出生时睾丸已在阴囊,以后分别在1、3、9个月时降至阴囊者皆有。认为足月婴在6周内或未成熟婴在3个月内睾丸不能达阴囊底部,则睾丸将不再移行下降。报道虽有隐睾可继续下降至青春期的提法,但其间可能与回缩睾相混杂,二者应予区分。真正的隐睾在1岁之后稀有再下降的,因此虽不可过早结论隐睾,但也不宜长期等待观望,况且多数未降的睾丸是体小质差,久留腹内将更影响发育。我院对隐睾与正常睾进行活检后光镜与电镜下对照观察发现:①隐睾的曲精细管周围纤维化,间质比例增加,可见曲精细管退化形成的沙样瘤,这些病变最早发生在2～4岁。MTD(平均曲精管直径)与 Cryptorchidism is a common disease in children, because it can affect fertility and possible cancer, need reasonable treatment. However, appropriate treatment of age and methodological issues are worth exploring. Now based on the clinical and experimental research hospital data combined with the literature discussed below. First, the treatment of the most appropriate age Someone surveyed 3,612 baby boys, 97.3% of full-term infants and 79% of immature infants were born testis in the scrotum, respectively, after 1,3,9 months were reduced to scrotum Jieyou. That full-term infants in 6 weeks or immature infants within 3 months of testicular can not reach the bottom of the scrotum, the testicles will no longer migrate down. Although there are reports of cryptorchidism may continue to decline to adolescent formulation, but during which may be mixed with the contractile testicular, the two should be distinguished. True cryptorchidism rare again after the decline in the 1-year-old, so although the conclusions can not be too early cryptorchidism, but also should not wait and see for a long time, Moreover, the majority of the testicles are not low quality of body mass difference, long stay within the abdomen will be more affected development. My courtyard on cryptorchidism and normal test biopsy after light microscopy and electron microscopy under the control of the observation: ① cryptorchid testis around the fine fibrosis, increased proportion of interstitial, showing the song of fine tube degradation of the formation of sand tumor, the earliest of these lesions Occurs in 2 to 4 years old.
