Almost every male infant or baby has congenital phimosis. However in most children the prepuce becomes spontaneously retractable with the growth and erection of the penis during the first two years of life. The preputial orifice often became thicker and a fibrous ring made the foreskin less elastic and extensible. Dilation by one attempt in such cases often resulted in failure. Our experience suggests that the optimum age for balloon dilation is 2-4 years.
Balloon dilation is almost nontraumatic and time to accomplish the treatment is relatively short.
Almost every patient cooperated well, and no allergic reaction has been found so far. Balloon dilation should not be carried out if there is inflammation. Dilation of the prepuce should be terminated if the balloon waist disappears or when the balloon diameter is 3-5mm greater than that of glans penis. The prepuce is retracted 3-3 times daily for two weeks. Parogen should be applied to prevent secondary adhesion or paraphimosis.
