Description
Summary:Objective To define and describe a type of pseudo-malfunction of the Coloplast Titan Inflatable Penile Prosthesis (IPP) One-Touch Release (OTR) pump (Coloplast Corp, Minneapolis, MN). Materials and Methods We retrospectively reviewed a consecutive series of 550 patients with refractory organic erectile dysfunction who were implanted with a Coloplast Titan IPP with the OTR pump during a period of approximately 4 years. Results All patients were implanted using standard techniques through an infrapubic or penoscrotal approach. Twenty-nine patients (5.3%) complained that their IPP would not inflate and that the pump bulb felt “hard.” Examination revealed that their IPP was working normally; however, the inflate/deflate valve disc had become stuck in the deflate position. Very firm pressure had to be applied to the pump bulb to move the valve disc into the inflate position. Once this was accomplished, the device inflated and deflated normally. Another 14 patients (2.5%) reported this phenomenon to us but were able to apply enough pressure on the pump bulb to rectify it. Conclusion The inflate/deflate valve disc in the Coloplast Titan OTR pump can occasionally become stuck in the deflate position (7.8% of patients in our experience). Patients may be unable to inflate the device and return for evaluation. In all cases we have encountered, firm pressure on the pump bulb caused the valve to shift into the inflate position, and the device worked properly thereafter. Patients and implanting urologists should be aware of this issue and of the way in which it can be rectified.
