Purpose of reviewVascularized composite allotransplantation (VCA) has developed over the past 20 years, resulting in promising new reconstructive prospects for extensive soft tissue defects. More than 200 VCAs have been performed worldwide, including five genitourinary (GU)VCAs and here we review the most recent literature in this field. Recent findingsDevelopments in GUVCA are continuously evolving to improve patient outcomes and suggest ethical equivalency to solid organ transplant. Recent treatment options have focused on preventing GUVCA complications by acknowledging the immunogenic tissue composition of the penis to treat rejection episodes and implementing stem cell transplant to recognized the GUVCA as self. Utilizing modern, postoperative, treatments can minimize complications and although the ethical dilemma remains, the morality of performing a GUVCA has diminished. The ethical focus relic's on standardization of patient safety. SummaryGUVCA has become an established reconstructive surgical option. The prospect of VCA's future insinuates systemization between multidisciplinary VCA programs and the United Network for Organ Sharing in efforts to endorse ethical standardization. Over the last five years, the unprecedented outcomes have shown purpose to GUVCA that initiates an obligation to help those with severe genitourinary tissue defects. Progress in immunobiology continues to evolve optimal immunosuppression drug regimens and tolerance induction protocols, highlighting potential new immunologic pathways for graft acceptance.
