Nephron-sparing surgery for clear cell carcinoma in a solitary functional kidney. Case report and literature review.

Background: Since the introduction of nephron-sparing surgery, patients with small renal masses and diseases affecting overall renal function have greatly benefited.

Clinical Case: We present the case of a 62-year-old male with a 6-cm left renal tumor in the medial parahilar segment with right renal unit functionally excluded, secondary to chronic obstruction due to ureteral lithiasis. Right ureteroscopy was performed with pneumatic lithotripsy.
