Treatment Outcomes for Percutaneous Nephrolithotomy in Renal Allografts

Abstract

PURPOSE: We reviewed our experience with percutaneous nephrolithotomy (PCNL) in patients with renal allografts over 19 years. MATERIALS AND METHODS: We cross-referenced all renal allograft recipients at our institution with all PCNLs performed. We identified 16 renal allograft recipients who underwent a total of 21 PCNL procedures between 1986 and 2005. These charts were abstracted and the outcomes reviewed. RESULTS: The mean follow-up was 7.2 years. No loss of renal function occurred in the perioperative period. Five patients lost graft function during the follow-up period; however, none of these patients' loss of function was related to the PCNL. No patient had sepsis. Thirteen of the 16 patients were rendered stone free during long-term follow-up. CONCLUSIONS: PCNL is a safe and effective method of treating nephrolithiasis in a transplanted kidney.
