ABSTRACT
INTRODUCTION:
Infection is the worst complication seen with inflatable penile prosthesis (IPP). Both the American Medical Systems (AMS) and Coloplast IPP have infection retardant coatings. AMS is coated at the factory with rifampicin and minocycline (InhibiZone). The Coloplast IPP has a hydrophilic coating covalently bonded to its components that will absorb any aqueous solution before implantation and provides increased surface lubricity to decrease bacterial adherence.AIM:
We tested several antibiotic dips comparing zones of inhibition (ZOI) against five commonly infecting bacteria with coated Coloplast implants. Results were compared with those ZOI created with strips of an AMS IPP precoated with InhibiZone.METHODS:
Pieces of sterile Coloplast Titan IPP were dipped in (i) trimethoprim/polymixin B ophthalmic solution; (ii) trimethoprim/sulfamethoxazole infusion solution; (iii) bacitracin; (iv) rifampicin/minocycline; and (v) rifampin/trimehtoprim/sulfamethoxazole. ZOI for the Titan strips and for AMS InhibiZone coated strips were tested against Staphylococcus epidermidis, Staphylococcus lugdunensis, Staphylococcus aureus, Pseudomonas, and Enterococcus. MAIN OUTCOMEMEASURE:
ZOIs of the Coloplast Titan for each of the medicated solutions were compared with ZOI created by undipped strips of a sterile InhibiZone coated IPP placed on plates of the identical bacteria.RESULTS:
All dips except bacitracin showed ZOI≥InhibiZone (P≥0.005) for most organisms. Because of broad-spectrum effectiveness, ease of handling, and cost, infusion vial of trimehtoprim/sulfamethoxazole seemed optimal at this time. If trimehtoprim/sulfamethoxazole is unavailable; the ZOI with Polytrim ophthalmic solution zones were almost as good.CONCLUSIONS:
The Coloplast strips when dipped in several solutions showed equal or significantly larger ZOI against commonly infecting organisms than the InhibiZone coated strips. At the present time using off the shelf trimethoprim sulfamethoxazole infusion solution seems optimum. The flexibility of choosing the drug eluting from the Coloplast device seems promising in the changing bacterial environment.
