Overview

Dr. Doumanian is fellowship trained in urologic trauma and genitourinary reconstruction. He joined USC after five years as Director of Genitourinary Trauma and Reconstruction at Temple University Hospital in Philadelphia. Dr. Doumanian specializes in complex surgical management of traumatic, iatrogenic and radiation-induced genitourinary injuries and congenital and acquired diseases of the lower urinary tract and male genitalia. His particular interests include reconstruction of pelvic fracture urethral distraction defects (PFUDD), urethral strictures, penile curvatures and rectourethral fistulae. Additional focus includes corrective surgery for concealed/buried penis, genital lichen sclerosus and Fournier’s gangrene. Dr. Doumanian also has extensive experience treating male incontinence, erectile dysfunction, urinary diversions and neurogenic voiding dysfunction. Over the years, he has acquired unique surgical skills practiced by few urologists. These include skin, lingual and buccal grafts, and advanced muscle and tissue flap transfers. Dr. Doumanian feels these innovative graft and flap techniques improve success, increase patient satisfaction and enhance cosmetic outcomes in genitourinary reconstructive repair. His current research interests include developing standardized protocols to follow post-urethroplasty patients and ascertaining whether racial disparities exist in treatment of urethral stricture disease. Dr. Doumanian has been designated a reconstructive expert and educator by International Volunteers of Urology (IVU). In successful charity campaigns in Mozambique, Kenya and Rwanda, he partnered with local surgeons, residents and medical students for operative instruction in genitourinary reconstruction. His long-term philanthropic goals include recruitment and funding for USC resident participation in IVU.
