Current status of open partial nephrectomy

Area of Science:

• Urology
• Oncology
• Nephrology

Background:

• Renal tumors are a growing concern, necessitating effective surgical interventions.
• Nephron-sparing surgery aims to preserve renal function while removing tumors.
• Open partial nephrectomy (OPN) has been a cornerstone of treatment for renal masses.

Purpose of the Study:

• To evaluate the current role and efficacy of open partial nephrectomy (OPN) in treating renal tumors.
• To compare OPN with alternative surgical approaches for renal masses.

Main Methods:

• Review of current clinical practices and indications for OPN.
• Analysis of long-term outcome data comparing OPN with radical nephrectomy and laparoscopic partial nephrectomy.

Main Results:

• OPN is indicated for tumors in solitary kidneys, bilateral masses, or impaired renal function, and small unilateral masses (<4 cm).
• Laparoscopic partial nephrectomy offers comparable oncological results to OPN but may have a higher complication rate.
• OPN is justified for intermediate-risk patients with tumors up to 7 cm and demonstrates long-term cancer-free survival similar to radical surgery, with improved renal function and reduced mortality.

Conclusions:

• Open partial nephrectomy remains the gold standard for small renal masses.
• OPN is increasingly recommended for selected patients with renal tumors up to 7 cm in diameter.
• OPN provides significant benefits in renal function preservation and overall patient outcomes.
