[Key issues of nephron spring surgery for renal neoplasms]

Area of Science:

• Urology
• Surgical Oncology

Background:

• Small renal carcinoma incidence is rising globally.
• Nephron sparing surgery (NSS) is the preferred treatment for localized renal tumors.
• Comprehensive patient and tumor evaluation is crucial for NSS decision-making.

Purpose of the Study:

• To outline the key considerations and techniques for successful nephron sparing surgery.
• To emphasize the importance of intraoperative assessment and renal function preservation.

Main Methods:

• Review of current practices in nephron sparing surgery for small renal carcinoma.
• Discussion of surgical approaches: intraperitoneal, retroperitoneal, and combined.
• Emphasis on intraoperative frozen pathology and margin assessment.

Main Results:

• NSS requires careful preoperative evaluation, including imaging and systemic assessment.
• Intraoperative frozen pathology guides decisions on margin management or conversion to radical nephrectomy.
• Minimizing warm ischemia time is vital for protecting renal function and preventing atrophy.

Conclusions:

• Successful NSS depends on accurate preoperative assessment, appropriate surgical technique, and meticulous intraoperative management.
• Attention to surgical skill and renal function preservation improves patient survival and quality of life.
• Optimizing NSS reduces postoperative complications and enhances long-term renal health.
