Analysis of Complications and Causes of Revision of Penile Prosthesis / 대한남성과학회지

ABSTRACT

PURPOSE: Penile prosthesis implantation to correct the irreversible erectile dysfunction is a common. We investigated complications and causes of revision after implantation of the penile prosthesis. MATERIALS AND METHODS: We followed 72 patients who underwent penile prosthesis implantation performed by the same surgeon from January 1993 to July 2006. The medical records of all patients were retrospectively reviewed. The mean follow up duration was 30.3 months, and average age at operation was 56.7+/-11.0 years. RESULTS: The malleable penile prosthesis was implanted on 8 patients. The inflatable penile prosthesis was implanted on 63 patients and Dynaflex was implanted in the one patient. Of the patients implanted inflatable penile prosthesis, complications were developed in the 14 patients and 17 cases of complications were developed. Of the complications, mechanical complications were broken of connecting tubing(7), mulfunction of Dynaflex(1) and difficulty of deflation(1). Of 17 complications, non-mechanical complications were urethral stricture(5), erosion of urethra(1), migration of reservoir into the bladder(1) and SST deformity(1). CONCLUSIONS: Penile prosthesis has high complications rates, and revision rate also is high. Mechanical failure was the most common cause of surgical revision. Although urethral stricture is rare complication, it was developed in the 5 patients due to mal-rotation of the cylinder.
