Tumor Enucleation of Renal Cell Carcinoma in a Solitary Kidney

We describe the case of a 57 year old man with a solitary kidney after undergoing resection of a Wilm's tumor as a child and a recent left partial colectomy who presents with an incidentally found clinical T1b renal mass. The patient underwent tumor enucleation and had no change in his renal function twelve days after surgery as compared to his preoperative baseline, highlighting the additional nephron-sparing associated with tumor enucleation as compared to partial nephrectomy that includes a gross margin of normal parenchyma.
