Use of CX cylinders in association with AMS700 inflatable penile prosthesis

Recently the triple-layered CX or controlled expansion cylinders were introduced, which consisted of a middle layer of expandable monofilament knitted polypropylene-like material sandwiched between 2 silicone layers. These cylinders provide uniform nonaneurysmal expansion to a girth of 18 mm. CX cylinders were implanted in 34 patients for a variety of situations. The results have been gratifying in each case and patient satisfaction has been high.
