A 30 year old male presents with pain on the right flank and hematuria. A CECT abdomen reveals a large 8×8 cm sized solid mass in the right kidney and 3×3 cm solid mass occupying the upper pole of left kidney. The most appropriate surgical treatment for this pt is:

**Core Concept**
The patient is diagnosed with bilateral renal cell carcinoma, a type of kidney cancer that requires surgical intervention. The goal of treatment is to remove the tumor while preserving renal function.

**Why the Correct Answer is Right**
The patient's condition is a classic indication for nephron-sparing surgery, also known as partial nephrectomy. This approach involves removing the tumor while preserving as much healthy kidney tissue as possible. The right kidney has a larger tumor, and the left kidney has a smaller tumor, making partial nephrectomy the most appropriate surgical treatment. This approach is preferred to radical nephrectomy, which involves removing the entire kidney, as it helps maintain renal function and reduces the risk of chronic kidney disease.

**Why Each Wrong Option is Incorrect**
**Option A:** Radical nephrectomy is not the best option for this patient, as it would involve removing the entire right kidney, which is not necessary given the smaller size of the left kidney tumor.
**Option B:** Nephroureterectomy is a procedure that involves removing the kidney and ureter, which is not indicated in this case as the patient has bilateral renal cell carcinoma.
**Option C:** Laparoscopic surgery is a suitable approach for partial nephrectomy, but it is not a specific surgical treatment option.

**Clinical Pearl / High-Yield Fact**
Partial nephrectomy is a preferred treatment option for patients with bilateral renal cell carcinoma to maintain renal function and prevent chronic kidney disease.

**Correct Answer: C. Laparoscopic partial nephrectomy.

✓ Correct Answer: C. Right radical nephrectomy and left partial nephrectomy.
