Partial Component Exchange of a Non-Infected Inflatable Penile Prosthesis is Associated With a Higher Complication Rate

OBJECTIVE To describe the infectious and non-infectious complications in men undergoing Inflatable penile pros-thesis (IPP) revision with partial and complete component exchange for mechanical malfunction. METHODS We performed a multicenter retrospective cohort study of patients who underwent IPP revision. Men undergoing procedures for implant infection were excluded. Patients were divided into those who had complete exchange of the entire device or partial exchange of only one or 2 components. Infectious and non-infectious complications were compared between groups. RESULTS Three hundred sixty-eight men had complete exchange of the entire device and 85 had partial component exchange. Men undergoing partial exchange had a significantly higher infection rate (7.1% vs 2.2%, P = .031). The partial exchange group also was more likely to receive antifungals (51.8 vs 16.6%, P < .001), have a modified salvage washout (77.4 vs 60.2%, P = .004), and less likely to receive vancomycin and gentamicin (63.5 vs 83.7%, P < .001). Time to revision was sig-nificantly shorter in the partial exchange group (44.9 vs 168.2 months, P < .001). Mean follow-up was slightly longer in the complete exchange group (18.3 vs 13.0 months). In multivariable analy-sis, partial exchange surgery, vancomycin and gentamicin prophylaxis, modified salvage washout, and antifungal prophylaxis were no longer associated with postoperative infections. The partial exchange group had greater rates of non-infectious complications (21.2% vs 9.5%, P = .005) such as pump malfunction and tubing breakage. CONCLUSION Patients undergoing partial component revision had more infectious and non-infectious complica-tions. These findings suggest that partial component exchange increases complications in men undergoing IPP revision. UROLOGY 174: 128-134, 2023. Published by Elsevier Inc.
