Paraphimosis

Caused when the foreskin of an uncircumcised penis is retracted and left behind the glans, leading to vascular engorgement and edema of the distal glans.

In its acute form, it is a medical emergency requiring rapid evaluation and possible surgical decompression.

Can occur at any age but is most common in children and older people.

Circumcision is preventative and is curative if the process develops.

Most cases are iatrogenic in etiology.

Paraphimosis is a condition caused when the foreskin of the uncircumcised penis is retracted and left behind the glans penis, leading to vascular engorgement and edema of the distal glans.[1]McGregor TB, Pike JG, Leonard MP.
