[Anatomic study of pelvic urethra in women: value of its conservation in radical cystectomy].

The vascularization of the different layers of the pelvic urethra was studied in 12 females urethras, in which the vascular system was injected with gelatinous inda ink. The arterial vascularization of the striated muscle is essentially tributary of the sub-mucosal network by the intermediary of fascicular and interfascicular arteries which anastomose to form an intermuscular plexus. This plexus also anastomoses with the subserosal network.
