Paraphimosis can occur when the foreskin of an uncircumcised male is left retracted behind the glans penis (Fig. 65.1). As a result a tight constrictive band of tissue causes edema and swelling of the glans due to lymphatic and venous congestion, which makes it unable to pull back the foreskin easily to its anatomic position . This can happen when the foreskin is retracted in male with relative phimosis or because of the failure to return the foreskin to its normal position after urination, washing, or inserting a transurethral catheter. Besides, it can occur after direct trauma to the area, postcoital, or due to infection.
