Abstract

Longstanding, unrecognized staghorn stones remain a major cause of morbidity in the form of pain, infection, and functional impairment of the affected kidney. Squamous cell carcinoma of the upper urinary tract is associated with stone disease and chronic infection, but the association with transitional cell carcinoma (TCC) has not been proven. We report a case of a 73-year-old man presenting with right flank pain with episodes of total gross hematuria for 1 year. An abdominopelvic computed tomography scan showed decreased parenchymal enhancement and staghorn stones in the right renal pelvis and multiple tiny calyceal stones with severe hydronephrosis. The patient underwent a simple nephrectomy. Histopathologic analysis revealed staghorn stones combined with high- grade papillary TCC of the renal pelvis. The tumor was extended into the peripelvic fat and renal parenchyme (pT3NoMo).
