Clinical experience with Scott inflatable penile prosthesis in 150 patients.

The Scott inflatable penile prosthesis was implanted in 150 patients with organic (89%) and psychologic (11%) impotency from 1979 to 1982. The patients were followed up for an average of twenty-five (6-46) months. A satisfactory result was achieved in 133 (89%) patients. Forty-nine major complications occurred in 38 patients. Forty-four surgical procedures were performed in 33 patients to correct mechanical or technical complications (32), replace the device (9), or remove the device (3). Two patients refused corrective surgery, and the complications could not be corrected in 2 patients. Cylinder leaks (15), leaks at tubing/connector junctions (14), and cylinder aneurysms (7) were responsible for most of the mechanical failures. Additional refinements in surgical technique will not eliminate these problems. Device modifications should be made to increase cylinder durability, to eliminate the need for suture ligation of tubing/connector junctions, and to assure symmetrical cylinder expansion.
