Therapeutic living donor nephrectomy.

Therapeutic living donor nephrectomy is defined as a nephrectomy that is performed as therapy for an underlying medical condition. The patient directly benefits from having their kidney removed, but the kidney is deemed transplantable. The kidney is subsequently used as an allograft for an individual with advanced renal disease. Therapeutic donor nephrectomy can be successfully utilized for a heterogenous cohort of disease processes as both treatment for the donor and to increase the number of suitable organs available for transplantation. We describe four cases of therapeutic donor nephrectomy that were performed at our institution. Of the four cases, two patients elected to undergo therapeutic donor nephrectomy as treatment for loin pain hematuria syndrome; one after blunt abdominal trauma that resulted in complete proximal ureteral avulsion; and the fourth after being diagnosed with a small renal mass. Based on our data presented to the United Network for Organ Sharing Board of Directors (UNOS) in December 2015, living donor evaluation has been made simpler for patients electing to undergo therapeutic donor nephrectomy. UNOS eliminated the requirement for a psychosocial evaluation for these patients. As the organ shortage continues to limit transplantation, therapeutic donor nephrectomy should be considered when appropriate.
