Phimosis natural history, complications and prognosis

Chronic complications of acquired (pathological phimosis) can include discomfort or pain during urination or sexual intercourse. The urinary stream can be impeded, resulting in dribbling and wetness after urination. Harmful urinary obstruction is possible but uncommon. Pain may occur when a partially retractable foreskin retracts during intercourse and chokes the glans penis. A totally non-retractable foreskin is rarely painful. There is some evidence that phimosis may be a risk factor for penile cancer.^[1]

The worst acute complication is paraphimosis. In this acute condition, the glans is swollen and painful, and the foreskin is immobilized by the swelling in a partially retracted position. The proximal penis is flaccid. Paraphimosis is considered an emergency.
