HISTOLOGICAL ALTERATIONS IN CAVERNOUS TISSUE AFTER RADICAL PROSTATECTOMY

Progressive fibrosis in the corpora cavernosa after radical prostatectomy probably results from denervation and/or an ischemic process, which is caused in turn by the ligation of anomalous pudendal artery branches or of venous plexuses that drain to or from the corpora cavernosa. Fibrosis and the subsequent loss in elasticity and function of erectile tissue probably together cause erectile dysfunction.
