Nonprosthetic surgical strategies for impotence.

The past decade has seen a remarkable expansion of understanding of erection and the treatment of impotence. This has been brought about, in part, by improvements in radiographic techniques for selective pudendal arteriography and dynamic cavernosography, which, in turn, have made possible development of surgical techniques for the management of penile vascular insufficiency and corpus spongiosum venous leakage that yield good short-term results in restoring the capacity for penetration in impotent patients.
