The Inflatable Penile Prosthesis: Failure of the Rear Tip Extender in Reducing the Incidence of Cylinder Leakage

Abstract
Of 184 patients who have received an inflatable penile prosthesis since 1974, 43% have undergone reoperation, the majority of which were owing to cylinder leakage. Comparison by life-table analysis of cylinders placed before and after introduction of the rear tip extender does not show an improvement in cylinder survival to date.
