腹腔内的隐睾恶变机会比正常睾丸高 18～ 40倍[1] ,将隐睾固定到阴囊内或切除可以减少恶变。为减少无谓的手术探查 ,对不可触及睾丸的隐睾及无睾症术前诊断及手术探查指征尤为重要。我院 1982— 1999年共收治隐睾患儿 812例 876侧 ,43例侧手术证实为睾丸缺如 ,报告如下。1　临 Intraperitoneal cryptorchid malignancy is 18 to 40 times higher than normal testis [1], the cryptorchidism fixed to the scrotum or resection can reduce malignant transformation.
