Application of renal-rotation techniques in retroperitoneoscopic partial nephrectomy

Area of Science:

• Urology
• Surgical Oncology

Background:

• Retroperitoneoscopic partial nephrectomy (RPN) is a standard treatment for T1-stage renal carcinoma.
• RPN presents challenges due to a narrow operative space and complex surgical demands.

Purpose of the Study:

• To evaluate the safety and feasibility of employing renal-rotation techniques in RPN.
• To assess the efficacy of this approach for renal tumors in specific locations.

Main Methods:

• A cohort of 38 patients with stage T1N0M0 renal-cell carcinoma underwent RPN utilizing renal-rotation techniques.
• Procedures were performed between April 2012 and June 2014, with tumor locations including the ventral side, renal hilum, and inferior pole.

Main Results:

• All 38 RPN procedures were completed successfully without conversion to open surgery.
• No intraoperative complications occurred; only three postoperative complications were reported.
• Mean operative time was 59 minutes, mean blood loss was 40 ml, and mean ischemia time was 21 minutes, with no transfusions required.

Conclusions:

• Renal-rotation technique in RPN is a safe and feasible option for treating renal tumors.
• This technique is particularly effective for tumors located ventrally, at the renal hilum, or at the inferior pole.
• The study supports the wider clinical application of renal-rotation techniques in RPN.
