Implantable penile venous compression device: initial experience in the chronic canine model.
A prosthetic penile venous compression device was surgically placed in 14 dogs to assess the effects of chronic device implantation and repeated device cycling on cavernous tissue. Duration of device implantation ranged from 37 to 224 days; total number of device cycles ranged from 8 to 59. At recovery, erection was induced by electrostimulation of the pelvic nerve. The device successfully prolonged intracavernous elevation for as much as 30 minutes after inflation. Histologic examination of representative tissue sections through the corpora revealed no evidence of neural injury, vascular compromise, or tissue atrophy. The implantable venous compression device may offer an improved method of treatment of venogenic impotence.
