Double jeopardy? Renal-sparing management of simultaneous ipsilateral renal cell carcinoma and urothelial carcinoma.

The occurrence of renal cell carcinoma (RCC) and urothelial carcinoma (UC) synchronously in the same kidney is exceedingly rare. All reported cases have been managed with either nephroureterectomy or nephrectomy. We report on a patient who required renal-sparing management of his double malignancy, including open partial nephrectomy of his pT1a RCC and endoscopic laser ablation of his low-grade Ta renal pelvis UC. After 4 years, the patient is in good health and disease-free under strict surveillance. It, therefore, would appear justified to combine partial nephrectomy for RCC and endoscopic management of UC in the same kidney of an appropriately selected patient.
