PURPOSE: We compared the ability of the CX and Ultrex cylinders to straighten the penis in men who received a 3-piece AMS 700 series inflatable penile prosthesis for erectile dysfunction and erectile deformity due to Peyronie's disease. MATERIALS AND METHODS: The records of 34 and 38 patients receiving devices CX and Ultrex cylinders, respectively, were reviewed. RESULTS: All 34 patients receiving the CX cylinders achieved complete penile straightening with cylinder inflation and bending alone. In 10 of 38 patients receiving the Ultrex cylinders complete straightening with cylinder inflation and bending could not be achieved, and simultaneous corporoplasty was necessary. CONCLUSIONS: Girth expanding CX cylinders have better penile straightening properties than girth and length expanding Ultrex cylinders. We recommend use of CX cylinders for 3-piece AMS 700 series inflatable penile prosthesis implantation in men with Peyronie's disease.
