BACKGROUND
Few studies on foreskin development and the practice of circumcision have been done in Chinese boys. This study aimed to determine the natural development process of foreskin in children.
METHODS
A total of 10 421 boys aged 0 to 18 years were studied. The condition of foreskin was classified into type I (phimosis), type II (partial phimosis), type III (adhesion of prepuce), type IV (normal), and type V (circumcised). Other abnormalities of the genitalia were also determined.
RESULTS
The incidence of a completely retractile foreskin increased from 0% at birth to 42.26% in adolescence; however, the phimosis rate decreased with age from 99.7% to 6.81%. Other abnormalities included web penis, concealed penis, cryptorchidism, hydrocele, micropenis, inguinal hernia, and hypospadias.
CONCLUSIONS
Incomplete separation of foreskin is common in children. Since it is a natural phenomenon to approach the adult condition until puberty, circumcision should be performed with cautions in children.
背景
在中国男孩中，关于包皮发育和割礼实践的研究较少。本研究旨在确定儿童包皮的自然发育过程。
方法
共研究了 10421 名 0 至 18 岁的男孩。将包皮状况分为 I 型（包茎）、II 型（部分包茎）、III 型（包皮粘连）、IV 型（正常）和 V 型（割礼）。还确定了其他生殖器异常。
结果
完全可退缩的包皮的发生率从出生时的 0%增加到青春期时的 42.26%；然而，随着年龄的增长，包茎的发生率从 99.7%下降到 6.81%。其他异常包括阴茎蹼、隐匿性阴茎、隐睾、鞘膜积液、小阴茎、腹股沟疝和尿道下裂。
结论
儿童中不完全分离的包皮很常见。由于直到青春期才接近成人状态是一种自然现象，因此应谨慎在儿童中进行割礼。
