Transperitoneal laparoscopic partial nephrectomy using a new technique

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Transperitoneal laparoscopic partial nephrectomy is a standard procedure for kidney tumors.
• Managing upper pole renal lesions can present unique surgical challenges.
• A novel intraoperative kidney rotation technique was developed to address these challenges.

Purpose of the Study:

• To evaluate the feasibility and outcomes of a new transperitoneal laparoscopic partial nephrectomy technique.
• To assess the efficacy of intraoperative kidney rotation for upper pole renal masses.
• To analyze operative time, complications, and oncological results of this innovative approach.

Main Methods:

• Ten patients with upper pole renal lesions underwent transperitoneal laparoscopic partial nephrectomy.
• The kidney was mobilized and rotated 180 degrees to position the upper pole inferiorly.
• Resection beds were closed with sutures and clips, followed by kidney repositioning.

Main Results:

• The median tumor size was 58 mm; 9 patients had contrast-enhancing masses, 1 had a nonfunctioning pole.
• Median operative time was 206 minutes, with a mean warm ischemia time of 30 minutes.
• Negative surgical margins were achieved in all patients; complications included one instance of bleeding and one of prolonged urine leakage.

Conclusions:

• Intraoperative kidney rotation during laparoscopic partial nephrectomy for upper pole lesions is feasible.
• This technique provides acceptable operative times and complication rates.
• The upside-down approach enhances surgical field visualization, facilitating the procedure.
