To demonstrate the increase of preputial retractability with age. To point out the small usefulness of circumcision and preputial forced dilation during childhood.
The development of the prepuce and its retractability were evaluated in 1200 boys between 0 and 16 years. The prepuce was classified as type I to V depending on its lower or higher retractability in all cases having been dilated previously or not.
Prepuce retractability in boys under one year was type I (not retractile) in 63.4%, whereas it was type V (completely retractile) in only 3.7%. The contrary was observed in adolescents (11 to 16 years), in which type I was 0.9% and type V was observed in 80.9%. It was also observed that 309 boys (43. 1%) among the 717 with previous prepuce forced dilation, had types I to IV prepuces, so, they had acquired new balanopreputial adherences by the time of examination for our study. Seventeen boys (0.4%) required circumcision. No children suffered upper urinary tract infections.
All boys are born with the prepuce covering the glans penis, keeping adherences between both structures, which disappear with age, being the detachment complete at the time of puberty in most boys. So, we consider circumcision or forced dilation of the prepuce unnecessary in most boys.
证明包皮可退缩性随年龄增长而增加。指出儿童期包皮环切术和包皮强行扩张术作用不大。
对1200名0至16岁男孩的包皮发育及其可退缩性进行评估。根据包皮在先前是否已扩张的所有情况下的较低或较高可退缩性，将包皮分为I型至V型。
1岁以下男孩中，63.4%的包皮可退缩性为I型（不可退缩），而只有3.7%为V型（完全可退缩）。在青少年（11至16岁）中观察到相反情况，其中I型为0.9%，V型为80.9%。还观察到，在717名先前进行过包皮强行扩张的男孩中，有309名（43.1%）的包皮为I型至IV型，所以，在我们研究的检查时，他们形成了新的阴茎头包皮粘连。17名男孩（0.4%）需要进行包皮环切术。没有儿童发生上尿路感染。
所有男孩出生时包皮都覆盖着阴茎头，两者结构之间存在粘连，随着年龄增长粘连会消失，大多数男孩在青春期时粘连完全分离。因此，我们认为大多数男孩无需进行包皮环切术或包皮强行扩张术。
