Experience with the penile prosthesis and artificial urinary sphincter

The therapy of two common urologic problems, erectile dysfunction and urinary stress incontinence, has been revolutionized over the last 20 years by the incorporation of principles of hydraulic mechanics into the field of silicone prosthesis implantation. The inflatable penile prosthesis is surgically implanted into men with impotence due to organic or psychogenic etiology. The artificial urinary sphincter has found widespread use in males and females in both the adult and pediatric populations with stress incontinence from a variety of causes. Associated with these popular devices are various complications relating to the anatomic site as well as the host's immunologic response. The use of these implants, as well as the technologic innovations resulting from various adverse effects, are reviewed herein.
