Current status of partial nephrectomy for renal mass.

Area of Science:

• Urology
• Nephrology
• Surgical Oncology

Background:

• The standard treatment for small renal masses has evolved from radical nephrectomy to partial nephrectomy.
• Partial nephrectomy offers significant benefits, including renal function preservation, enhanced overall survival, and reduced risks of chronic kidney disease and cardiovascular events.
• Advancements in surgical techniques have led to shorter warm ischemic times and the ability to manage larger or endophytic renal masses.

Purpose of the Study:

• To review the current indications and advancements in partial nephrectomy for renal masses.
• To highlight the benefits and evolving techniques of partial nephrectomy in contemporary urological practice.

Main Methods:

• Review of current literature on partial nephrectomy techniques and outcomes.
• Discussion of the evolution from open to minimally invasive approaches, including laparoscopic and robotic surgery.
• Consideration of intraoperative adjuncts like ultrasound for endophytic tumors.

Main Results:

• Partial nephrectomy is increasingly favored for small renal masses due to its functional and survival benefits.
• Surgical expertise and procedural simplification have reduced warm ischemic times, expanding the applicability of partial nephrectomy.
• Laparoscopic partial nephrectomy is well-indicated for many renal tumors, while open partial nephrectomy remains crucial for complex cases.
• Robotic partial nephrectomy demonstrates comparable outcomes and offers advantages in challenging situations.
• Laparoendoscopic single-site partial nephrectomy is emerging as a feasible option for select cases.

Conclusions:

• Partial nephrectomy is the preferred treatment for small renal masses, preserving kidney function and improving patient outcomes.
• Minimally invasive approaches, including laparoscopic and robotic partial nephrectomy, are becoming standard, with ongoing innovation in techniques like single-site surgery.
• The choice of surgical approach (open, laparoscopic, robotic) depends on tumor complexity and surgeon expertise.
