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 repe ated device cycling on cavernous tissue. Duration of device implantati on ranged from 37 to 224 days; total number of device cycles ranged fr om 8 to 59. At recovery, erection was induced by electrostimulation of the pelvic nerve. The device successfully prolonged intracavernous el evation for as much as 30 minutes after inflation. Histologic examinat ion 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.
