Dr. Gretzer specializes in the management of urethral stricture disease and is one of a few Arizona urologists that routinely perform a high volume of complex urethral reconstruction (urethroplasty) cases.  In addition, he has advanced urologic training in all aspects of Genitourinary Reconstruction and Prosthetics, and performs numerous penile implant and artificial urinary sphincter cases both initial and revisional as referred from other urologists. The highly complex nature of these procedures improve the quality of life for these patients following cancer therapy and traumatic injury. Since joining the University of Arizona Division of Urology faculty in 2005, Dr. Gretzer has established the Division of Urology as a center of excellence in genito-urinary reconstruction. When he arrived, there were no other urethral reconstruction specialists in Arizona.  He has since worked hard to develop a wide referral network that spans all of Arizona as well as all of our neighboring states. As this program has matured in Arizona, patients are now routinely referred to the University of Arizona in Tucson for this unique management instead of being referred out of state.
