Cylinder aneurysm of parylene-coated American Medical System (AMS) 700CX penile prosthesis.
BACKGROUND
Cylinder aneurysms and leakages are uncommon with three-layered American Medical System (AMS) CX cylinders. Since 2001, an additional parylene coating improves cylinder wear.


OBJECTIVE
To report two patients in whom major cylinder aneurysms developed less than 4 years after implantation.


METHODS
Two patients in separate urologic private practices developed significant cylinder aneurysms requiring reoperation.


RESULTS
Both patients developed aneurysms in 21-cm parylene-coated CX cylinders just short of 4 years of inflatable penile prosthesis (IPP) placement. Both did well after the explantation and insertion of Coloplast Titan IPP (Coloplast; Minneapolis, MN, USA).


CONCLUSIONS
Longer AMS CX IPP cylinders may develop aneurysms more than 3 years after insertion.
