Summary
Nephron-sparing surgery (NSS) is increasingly justified for localized renal cell carcinoma, offering equivalent curative outcomes to radical nephrectomy, especially for smaller tumors.
Area of Science:
- Urology
- Surgical Oncology
- Nephrology
Background:
- Renal cell carcinoma (RCC) management is primarily surgical.
- Advances in imaging increase detection of incidental RCCs.
- Radical nephrectomy is often the standard for localized RCC with a healthy contralateral kidney.
Purpose of the Study:
- To evaluate the evolving indications for nephron-sparing surgery (NSS) in renal cell carcinoma.
- To compare the efficacy of NSS versus radical nephrectomy for localized RCC.
- To highlight factors supporting NSS as a viable alternative.
Main Methods:
- Review of recent data and surgical techniques.
- Analysis of studies on RCC biology and multifocality.
- Consideration of earlier diagnostic trends.
Main Results:
- Radical nephrectomy and NSS provide equivalent curative treatment for most renal cell carcinomas, particularly those ≤ 4 cm.
- Growing evidence supports NSS in select patients even with a normal contralateral kidney.
- Indications for NSS have expanded over the last decade.
Conclusions:
- Nephron-sparing surgery is an increasingly attractive option for urologists managing renal cell carcinoma.
- Refined surgical techniques and a better understanding of RCC biology support the expanded use of NSS.
- NSS offers a justifiable alternative to radical nephrectomy in appropriate clinical scenarios.
