[A Case of Two Percutaneous Nephrolithotomies for Recurrent Transplant Kidney Stones Following Ureteral Stenosis Surgery Performed after Kidney Transplantation].

Abstract

The patient was a 56-year-old woman who had previously undergone living-donor kidney transplantation, followed by urinary diversion surgery due to recurrent pyelonephritis. Nine years after the urinary diversion, abdominal computed tomography performed for evaluation of lower abdominal pain revealed a renal calculus in the transplanted kidney. Percutaneous nephrolithotomy resulted in satisfactory stone fragmentation, but had to be performed again 14 months later to remove a residual stone that had increased in size.
