Sn. Liberman et al., EXPERIENCE WITH THE ULTREX AND ULTREX PLUS INFLATABLE PENILE PROSTHESIS - NEW IMPLANTATION TECHNIQUES AND SURGICAL OUTCOME, International journal of impotence research, 10(3), 1998, pp. 175-179
The Ultrex and Ultrex Plus penile prosthesis incorporate sequential de
sign modifications that afford important functional advantages that re
duce the potential for mechanical failure. This retrospective study re
views our experience with these models emphasizing innovations in surg
ical technique and postoperative results. Implantation of Ultrex (31%)
and Ultrex Plus (69%) penile prosthesis was performed in 90 impotent
men with organic erectile dysfunction following comprehensive multi-di
sciplinary evaluation. During a follow-up interval of 7-50 months, pos
toperative outcome was assessed. Of this group, 10% underwent simultan
eous explant of another malfunctioning inflatable device or conversion
from a semi-rigid prosthesis due to patient preference. Of the remain
der, 20% selected implant surgery as their primary therapy while 73% w
ere initially treated with various nonsurgical options prior to implan
tation. In all patients rye employed a single peno-scrotal incision an
d applied the concept of controlled radial dilatation of all compartme
nts. In our last 32 consecutive patients including eight with previous
radical pelvic surgery, we utilized the preperitoneal distention ball
oon (PDB) facilitating safe and non-traumatic creation of the prevesic
al space for reservoir insertion. Post operative complications occurre
d in 8% of patients including pump infection and corporal deformity re
quiring reimplantation with AMS 700 CX cylinders, or self-contained un
itarian prosthesis as a salvage procedure. Satisfactory, functional an
d anatomic outcome was reported in 95% of patients. Interim advances i
ncorporated into the Ultrex and Ultrex Plus prosthesis have markedly r
educed mechanical failure during our follow-up interval of up to 50 mo
nths. Importantly, controlled, non-traumatic radial dilatation of the
prevesical space by the PDB may encourage broader use of the multicomp
onent inflatable models, particularly in a setting of pelvic fibrosis
due to previous pelvic surgery or radiation.
