Percutaneous Nephrolithotomy is a minimally-invasive procedure used in the setting of complex stone burden. Among its uses, PCNL can be employed to treated renal allograft calculi. This case presented a unique challenge and a rare usage of PCNL that involved removal of a 2.6 cm stone that presented in a 43-year-old male with dual renal allografts. The unique location of the allograft presented challenges that were navigated successfully with an uneventful postoperative course and no residual stone burden. The utilization of PCNL to treat calculi in dual renal allografts has been minimally reported in the literature.
