2. The Coloplast Titan inflatable penile prosthesis (IPP) was recently modified with a One Touch Release (OTR) pump, to facilitate deflation
The OTR pump became available in September of 2008
OTR pumps are now available as separate units, or pre-connected to cylinders
The objectives of this investigation were to assess the ease of implantation of this new pump, and to assess it’s functionality and ease of patient use, compared to the prior (Genesis) pump.

6. Methods
50 consecutive patients were implanted with a Titan IPP containing an OTR pump; some received a primary implant, others received an OTR pump during an IPP replacement procedure
Implantation was either via standard trans-scrotal or infrapubic technique
All procedures were done as an outpatient, by an experienced (>1000 cases) surgeon
All patients received IV vancomycin and gentamicin pre-op
Intra-op antibiotic irrigation and device soaking was carried out with rifampin and gentamicin, 1.0 mg. of each per ml of sterile water
Follow-up was obtained by retrospective chart review
The control group consisted of 50 consecutive patients implanted with a Titan IPP containing a Genesis pump, immediately prior to the availability of the OTR pump

7. Objective results Control Group (N=50) OTR group (N=50)
Mean follow up (mos.)
% follow-up
# of IPP infections
Average # of teaching visits
(p=.0004)
Range of teaching visits
# of pump malfunctions

8. Subjective results OTR pump just as easy to implant as Genesis pump
OTR pump easier for surgeon and patient to deflate
Genesis and OTR pumps equally easy to inflate
Genesis pump deflation requires continuous pressure on deflate bars, which some patients find difficult or painful
OTR pump deflation requires only one firm squeeze of the release pads

9. Conclusions With short term follow-up:
OTR pump functioned as specified by the manufacturer
No instance of OTR pump malfunction
OTR pump resulted in a statistically significant reduction in the number of post-op inflate/deflate patient teaching sessions (p=.0004)
OTR pump was subjectively easier for patient and surgeon to deflate; equally easy to inflate, compared to Genesis pump
A larger series with longer follow-up is needed to confirm these initial results
