To test the hypothesis that testicular maldescent is rarely congenital in the absence of a complete hernial sac.
The study comprised 110 boys undergoing orchidopexy. Operative findings (complete hernial sac versus no hernial sac) were compared with recorded testicular descent at birth.
Among 70 testes recorded as maldescended neonatally there was no example without a complete hernial sac at orchidopexy. Among 60 recorded as descended neonatally, 43 had no sac at orchidopexy.
The findings are consistent with the hypothesis, though not with the proposition, that the presence of a complete hernial sac at orchidopexy constitutes proof of congenital testicular maldescent.
验证在没有完整疝囊的情况下，睾丸未降很少是先天性的这一假说。
该研究纳入了110名接受睾丸固定术的男孩。将手术结果（完整疝囊与无疝囊）与出生时记录的睾丸下降情况进行比较。
在70个出生时记录为睾丸未降的睾丸中，睾丸固定术时没有一个没有完整疝囊。在60个出生时记录为已降的睾丸中，43个在睾丸固定术时没有疝囊。
这些发现与该假说一致，但与“睾丸固定术时有完整疝囊即构成先天性睾丸未降的证据”这一观点不一致。
