回缩性睾丸49例临床观察

Clinical observation of retractile testis in 49 patients

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 explore the characteristics and therapy principle of retractile testis. Methods Forty-nine patients with retractile testis were followed up to observe the changes of location of retractile testis and to analyze the probability and the age of becoming cryptorchidism and its therapy. And the patients with retractile testis （observation group） and another 60 patients with congenital cryptorchidism （control group） were compared the operation age. Results The age of initially diagnosed retractile testis was from 1.5 to 11.5 （5.0±2.8） years old in observation group. Through follow-up survey for 6 to 59 （32±12） months, testis descended in scrotum in 26 patients （53.1%）, remained retractile in 14 （28.6M）, and resulted in cryptorchidism in 9 （18.3%）. The patients received orchiopexy were at the age of 2.5 to 12.8 （7. 3±2. 7） years old in observation group and 0. 8 to 4. 5 （2. 1±0. 8） years old in control group, showing a significant difference between two groups （P 〈 0.01）. Conclusions Retractile testis has a risk of developing to cryptorchidism. Orchiopexy is an effective method for cryptorchidism.
