The foreskin cannot be completely turned up to reveal the glans. The physiological adhesion between the foreskin and the glans is normal in infancy, and as the penis grows and develops, the adhesion is gradually separated and absorbed, and the foreskin can recede upwards on its own. less than 1% of young people have prepuce after the age of 17.
1, etiology Congenital prepuce is due to the physiological narrowing of the foreskin mouth, most can be self-healing with the growth of age.
Acquired prepuce is mostly secondary to circumcision of the head of the penis, and injury to the foreskin and glans. The foreskin mouth forms scar, loses elasticity, causes contracture, the ability to expand disappears, the foreskin cannot retreat upward, often accompanied by urethral stenosis, this kind of prepuce will not heal itself.
2.Symptoms The prepuce is manifested as narrow foreskin mouth, pinhole-like, difficult to turn up, there can be different degrees of difficulty in urination, the urine flow is slow and small, and the foreskin puffs up when urinating.
Under the foreskin can accumulate prepuce consisting of sebaceous gland secretions and epithelial debris, prepuce can cause foreskin inflammation of the head of the penis, acute inflammation, the foreskin mouth red and swollen, with purulent discharge.
3, treatment (1) under 5 years of age without urinary difficulties, no infection of the prepuce do not have to deal with.
(2) Symptomatic children can try to expand the foreskin mouth first. The foreskin will be turned up repeatedly on a trial basis, so that the opening of the foreskin can be expanded to reveal the glans, remove the foreskin scale, apply antibiotic ointment to lubricate it, and then restore the foreskin. Most children can be cured by this treatment as they grow older.
(3) Circumcision, for ① scarring narrowing of the foreskin mouth; ② recurrent episodes of penile head circumcision. Simple circumcision should be frequently turned up and cleaned to maintain local cleanliness, without surgery.
(4) Penile head circumcision. Apply antibiotics in the acute stage, local soak with 4% boric acid solution or rehabilitation new liquid several times a day, after the inflammation subsides, try to separate the foreskin by hand, local cleaning treatment, and do circumcision when it is not effective.
