Paraphimosis

Definition of Paraphimosis

Paraphimosis occurs when the foreskin of an uncircumcised male cannot be pulled back over the head of the penis.

Causes, incidence, and risk factors

Causes of paraphimosis include:

Symptoms

The foreskin is pulled back (retracted) behind the rounded tip of the penis (glans) and stays there. The retracted foreskin and glans become swollen. This makes it difficult to return the foreskin to its extended position.

Signs and tests

A physical examination confirms the diagnosis. The health care provider will usually find a “doughnut” around the shaft near the head of the penis (glans).

Treatment

Pressing on (compression of) the head of the penis while pushing the foreskin forward may reduce the swelling due to paraphimosis. If this fails, prompt surgical will be needed.

Expectations (prognosis)

The outcome is likely to be excellent if the condition is diagnosed and treated quickly.
