Paraphimosis occurs when the foreskin of an uncircumcised male cannot be pulled back over the head of the penis.
Causes of paraphimosis include:
Injury to the area
Failure to return the foreskin to its normal location after urination or washing. (This is more common in hospitals and nursing homes.)
Infection, which may be due to not washing the area well
Men who have not been circumcised and those who may not have been correctly circumcised are at risk.
Paraphimosis occurs most often in children and the elderly.
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.
Inability to pull the retracted foreskin over the head of the penis
