Retroperitoneoscopic partial nephrectomy using a 980/1470-nm dual-diode laser for small exophytic renal tumors

Area of Science:

• Urology
• Minimally Invasive Surgery
• Oncology

Background:

• Laparoscopic partial nephrectomy is a standard treatment for small renal masses.
• Laser-assisted techniques are emerging to improve outcomes.
• The 980/1470-nm dual-diode laser system is a novel tool for this procedure.

Purpose of the Study:

• To evaluate the feasibility, oncological, and functional outcomes of laparoscopic partial nephrectomy using a 980/1470-nm dual-diode laser.
• To assess the safety and efficacy of this technique in treating small renal masses.

Main Methods:

• Retrospective review of 25 patients with small exophytic renal tumors.
• Laparoscopic partial nephrectomy performed using a 980/1470-nm dual-diode laser.
• Analysis of surgical data, complications, pathological variables, and oncological/functional outcomes.

Main Results:

• Mean operative time was 104.4 minutes with a median estimated blood loss of 100 ml.
• No major complications (Clavien-Dindo >II) occurred.
• No positive surgical margins, recurrence, or metastasis were observed during a mean follow-up of 24 months.
• Hemoglobin decreased by 9 g/l (P<0.001), and eGFR showed a non-significant decrease of 1.4 ml/min at 6 months (P=0.463).

Conclusions:

• Laparoscopic partial nephrectomy with a 980/1470 nm dual-diode laser is a feasible and oncologically sound technique for small renal masses.
• This laser system may offer advantages in reducing warm ischemia time.
• The technique demonstrates favorable functional and oncological results.
