PURPOSE
It has been speculated that late spontaneous testicular descent occurs in more than 70% of newborns with cryptorchidism. Based on this belief, the decision for orchiopexy is often deferred during infancy. We reviewed our 10-year experience of treating infants with cryptorchidism to document the rate of spontaneous testicular descent.
MATERIALS AND METHODS
A total of 1,235 patients with cryptorchidism were referred to our pediatric urology clinic between 1990 and 2000. Of these patients 278 presented before age 12 months. The medical records were reviewed explicitly to document the rate of spontaneous testicular descent.
RESULTS
Spontaneous descent occurred in only 6.9% of patients with cryptorchidism reexamined at age 1 year or beyond. All patients with eventual spontaneous descent initially presented by age 6 months. Of those initially presenting beyond age 6 months no patient had spontaneous testicular descent.
CONCLUSIONS
Contrary to previous belief, spontaneous testicular descent is uncommon in infants with cryptorchidism and is rare beyond age 6 months.
目的
据推测，超过70%的隐睾新生儿会出现晚期自发性睾丸下降。基于这一观点，婴儿期睾丸固定术的决策往往被推迟。我们回顾了我们10年来治疗隐睾婴儿的经验，以记录自发性睾丸下降的发生率。
材料与方法
1990年至2000年间，共有1235例隐睾患者转诊至我们的儿科泌尿外科诊所。其中278例在12个月龄之前就诊。对病历进行了详细审查，以记录自发性睾丸下降的发生率。
结果
在1岁及以上接受复查的隐睾患者中，仅6.9%出现自发性下降。所有最终出现自发性下降的患者最初均在6个月龄前就诊。在最初6个月龄后就诊的患者中，没有患者出现自发性睾丸下降。
结论
与先前的观点相反，隐睾婴儿中自发性睾丸下降并不常见，6个月龄后更是罕见。
