[Inverted papilloma of the renal pelvis].
A 60-year-old man with inverted papilloma of right renal pelvis is presented. On visit to hospital for benign prostatic hyperplasia with prostatic stone, he was found to have microscopic hematuria and intravenous pyelography and retrograde pyelography demonstrated a filling defect with papillary contour. We diagnosed a right renal pelvic tumor, which showed to be low grade because of negative cytology. Therefore, we performed tumor resection with renal preservation. Pathological diagnosis was inverted papilloma. From the Japanese and foreign literature, 16 cases of renal pelvic inverted papilloma were collected. They were reviewed clinically and pathologically, and the therapy was discussed.
