[Cowper's gland: anatomic, physiological and pathological aspects].

Cowper's glands are small appendages of the male genital tract, that are sometimes observed on intravenous urography voiding films. They are involved in the immune defence of the genitourinary tract, play a role in fertility, and secrete many glycoproteins, including PSA. They can be visualized in the form of a duct image parallel to the urethra, sometimes associated with opacification of the gland on IVU. This image can be differentiated from a fistula, extravasation of contrast agent, urethral duplication, or an artefactual image, by the course parallel to the urethra, the upper limit not exceeding the urogenital diaphragm, and the position of the orifice. These glands can be affected by neoplastic, infectious, stone and especially cystic disease: syringocele. The physician should think of these glands in patients with unusual genitourinary symptoms in order not to miss disease of these organs, and to prescribe appropriate treatment.
