Kyste rétroprostatique drainant les canaux éjaculateurs avec azoospermie obstructive secondaire

Abstract

Obstructive azoospermia constitutes 35 to 40% of azoospermia. Etiologies may be acquired or rarely congenital. Congenital utricular or Mullerian duct cyst may result in compression of ejaculatory ducts. However, they must be differentiated from exceptional wolffian or urogenital cysts, which are located at the same site but in which ejaculatory ducts may drain inside. We report a case of retroprostatic duct cyst diagnosed during work up of male infertility where magnetic resonance imaging (MRI) showed the drainage of both ejaculatory ducts inside and the presence of a thin canal ended blindly in the wall of prostatic urethra. Transurethral resection guided by MRI has been performed resulting in urethral drainage of the cyst, relieving of obstruction and normalization of spermogramm.
