Ureteroscopy for renal allograft lithiasis: institutional experience and global insights from a systematic review.

ABSTRACT:

Background

Renal allograft lithiasis (RAL) is a rare but potentially serious complication following kidney transplantation. Traditionally, ureteroscopy (URS) has been considered a second-line treatment for stones <15 mm, typically after failed extracorporeal shock wave lithotripsy (ESWL), due to concerns over challenging ureteral access.
