目的探讨回缩性睾丸的临床特点及诊治原则。方法对49例回缩性睾丸患儿(观察组)进行随访,观察回缩性睾丸的位置演变,分析演变为隐睾的概率和年龄以及诊治原则,比较演变为隐睾患儿手术年龄与60例先天性隐睾患儿(对照组)手术年龄。结果观察组确诊回缩性睾丸年龄为1.5~11.5(5.0±2.8)岁;随访6~59(32±12)个月,26例(53.1%)睾丸自行下降至阴囊内,保持回缩状态14例(28.6%),睾丸上升演变为隐睾者9例(18.3%);观察组隐睾患儿手术年龄为2.5~12.8(7.3±2.7)岁,对照组手术年龄为0.8~4.5(2.1±0.8)岁,差异有统计学意义(P<0.01)。结论回缩性睾丸有演变为隐睾的可能,手术是治疗隐睾的有效方法。 Objective To investigate the clinical features and diagnosis and treatment of contractile testis. Methods 49 cases of children with contractile testis (observation group) were followed up to observe the evolvement of the contractile testis, to analyze the probability and age of cryptorchidism as well as the principle of diagnosis and treatment. Compared with the age of 60 Cases of children with congenital cryptorchidism (control group) surgery age. Results In the observation group, the age of the testis was 1.5 ~ 11.5 (5.0 ± 2.8) years old. During the follow-up period of 6 ~ 59 (32 ± 12) months, 26 (53.1%) testicles descended into the scrotum on their own, (28.6%), testicular rise evolved into cryptorchidism in 9 cases (18.3%). The operative age of observation group was 2.5-12.8 (7.3 ± 2.7) years old, while that of control group was 0.8-4.5 (2.1 ± 0.8) years old, the difference was statistically significant (P <0.01). Conclusion Retrograde testis may evolve into cryptorchidism. Surgery is an effective method to treat cryptorchidism.
