A 74-year-old male was referred to our hospital due to microhematuria that was pointed out at his health check-up. Cystoscopy showed many papillary bladder tumors under 5 mm in size. Intravenous pyelography also showed deformity of the right kidney and shadow defects in the left renal pelvis. ⋯ First, he received right radical nephrectomy, and secondly left nephroureterectomy and cystectomy. Our case should be called triple cancer because bladder cancer was thought to be daughter tumor of renal pelvic tumor. This is, to our knowledge, the 11th case report that occurred in the urinary tact, and the first case that needed total resection of urinary tract.

Paragangliomas are rare neuroendocrine tumors that arise from hyperplastic paraganglionic cells and occur in or near the ganglia of the autonomic nervous system. Paragangliomas are classed as either functional or nonfunctional based on production of catecholamines. We report a case of retroperitoneal nonfunctional paraganglioma, which was successfully resected. ⋯ Histological findings were of paraganglioma, and there was no surgical margin. The patient did not receive any further treatment. Nine months after surgery, there were no signs of tumor recurrence.
