This video covers the most daunting surgical challenge in prosthetic urology – the implantation of cylinders into scarred corporal bodies. The corporal scarring can be the result of previous removal of cylinders for infection, priapism or vascular insufficiency. The scarring is worse proximally with previous infection and worse distally after priapism. The video stresses that the tunnel technique requires special instruments of backward cutting scissors and cutting dilators called cavernotomes. To be successful the operator must have down sized implants available as these devices have narrower bases than the standard sized cylinders. The authors believe that this method of implanting into stenotic corpora is less complicated and has less complications than the standard excision of the fibrosis and reconstruction of the corpora with grafting.
