Robotic retroperitoneal partial nephrectomy.

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Robotic-assisted renal surgery is increasingly common, predominantly using a transperitoneal approach.
• The retroperitoneal approach offers direct access to the kidney's posterolateral surface and posterior hilar structures.

Purpose of the Study:

• To review recent publications on robotic retroperitoneal partial nephrectomy.
• To present the authors' experience with this technique.

Main Methods:

• Review of recent literature.
• Analysis of data from 68 patients who underwent robotic retroperitoneal partial nephrectomy since 2006.

Main Results:

• The retroperitoneal approach is technically feasible and ideal for posterior/lateral renal masses.
• This technique is associated with decreased operative times, reduced narcotic use, and faster bowel function return.
• No increase in perioperative complications was observed; the most common complication was arterial pseudoaneurysm (4.4%).

Conclusions:

• Robotic retroperitoneal partial nephrectomy provides direct renal hilum access and excellent visualization for posterior masses.
• The technique avoids bowel mobilization, leading to improved patient recovery.
• Current data suggest an encouraging outlook for robotic retroperitoneal partial nephrectomy.
