Phimosis
Phimosis is a tightness of the prepuce (foreksin) of the penis that prevents the retraction of the foreskin over the glans. The condition is usually congenital but it may be the result of an infection.
Uncomplicated pathologic phimosis is usually amenable to conservative medical treatment. Failure of medical treatment warrants surgical intervention, usually in the traditional form of a circumcision or preputioplasty.
