Metaplastic changes from urothelium to intestinal type epithelium in the renal pelvis are rare and have the potential of undergoing a malignant transformation to adenocarcinoma. We report a case of intestinal metaplasia in pyelocaliceal and urothelial systems associated to squamous metaplasia without residual urothelium, in a 73-year-old female patient’s right kidney, associated with pyelocaliceal lithiasis, and without malignant transformation. The patient underwent a nephroureterectomy. The metaplastic epithelium’s immunohistochemistry shows positivity to cytokeratin 20, low Ki-67 index, and a lack of expression of p53. In this case, terminal renal illness with the aforementioned metaplastic changes didn’t evolve towards adenocarcinoma, which indicates that intestinal metaplasia doesn’t always imply malignant transformation.
