In patients with bilateral RCC or a solitary kidney, which procedure is preferred?

• A. Partial Nephrectomy
• B. Radical Nephrectomy
• C. Cryoablation
• D. Immunotherapy

Answer: (A)

Preserving kidney tissue while treating the tumor is the main idea. In patients with bilateral renal cell carcinoma or a solitary kidney, the goal is to remove the cancer without sacrificing renal function, so dialysis won’t be needed if possible. Partial nephrectomy accomplishes this by excising the tumor with a small margin of normal tissue while leaving most of the kidney intact, providing oncologic control and maintaining nephron mass. Radical nephrectomy, by removing the entire kidney, risks severe renal failure when the other kidney isn’t present or is already compromised. Cryoablation can be used for select small tumors or patients who can’t undergo surgery, but it may have higher recurrence and isn’t as reliable for long-term control as a well-done partial nephrectomy in suitable cases. Immunotherapy targets systemic disease and does not offer the same renal-preserving potential for localized tumors.
