Introduction

1. No. 101 Mechanical reliability and clinical outcomes between AMS 700TM Ultrex and LGX cylinders: A single centre outcome study with a minimum of 2 years follow-up on the American Medical Systems inflatable penile prosthesis implantation Eric Chung and Ross Cartmill Department of Urology, Princess Alexandra Hospital, Brisbane QLD Australia • Introduction • Numerous technological advancements have been made to the American Medical Systems (AMS) 700 inflatable penile prosthesis (IPP). • AMS 700TMUltrex cylinder was first introduced in 1990 while AMS 700TM LGX cylinder was later conceived in 2007 to replace Ultrex cylinder. • To date there is no prospective study comparing Ultrex and LGX IPPs implantation. • Results • A total of 67 (38 Ultrex and 29 LGX) IPPs was implanted in the 2-year period (Table 1). • There was no statistical differences in age and causes of ED between the 2 groups. • The main cause of ED was post radical prostatectomy (35%). • The mean follow up for Ultrex and LGX groups were 35.1 (24-47) and 36.8 (28-47) months. • There was one intra-operative complication documented in the LGX group. • There were two mechanical failures (1 Ultrex and 1 LGX) but no device explantation for infective and/or eroded IPP. • The overall satisfaction on a 5-point scale was 4.8 in both groups with the majority of patients willing to undergo the same operation again. Aim To evaluate the clinical outcomes of Ultrex and LGX cylinders in terms of mechanical failure and infection rates in a single centre. Table 1: Comparison of clinical variables between AMS 700TM Ultrex and LGX cylinders • Methods • Prospective data collection of all consecutive patients who underwent IPP implantation for erectile dysfunction (ED) between December 2007 and December 2009. • All patients have failed medical therapy and received appropriate counselling. • Using telephone interviews and review of existing clinical database, all patients were followed up for a minimum of 24 months post penile prosthesis implantation. • The Ultrex and LGX groups were compared with regard to: 1) intra-operative complication, 2) mechanical failure caused by device malfunction, 3) device explants for infection and/or erosion, and 4) patient satisfaction. • Conclusions • There is no difference in the mechanical failure, prosthesis infection and patient satisfaction rates between AMS 700 Ultrex and LGX cylinders in the short term.
