Robot-assisted partial nephrectomy (RAPN) offers better outcomes than laparoscopic partial nephrectomy (LPN) for kidney tumors, showing reduced blood loss, shorter warm ischemia time, and improved early kidney function preservation.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Oncology

Background:

  • Partial nephrectomy is the gold standard for small renal masses.
  • Both robot-assisted partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) are established minimally invasive techniques.
  • Patient selection and surgeon expertise can influence outcomes.

Purpose of the Study:

  • To compare peri-operative and early renal functional outcomes of RAPN versus LPN for kidney tumors.
  • To identify predictors of favorable outcomes after partial nephrectomy.

Main Methods:

  • Retrospective analysis of 237 patients (146 LPN, 91 RAPN) undergoing partial nephrectomy.
  • Propensity-score matching to control for baseline confounders.
  • Defined favorable outcome by warm ischemia time (WIT), surgical margins, complications, and absence of CKD upstaging.

Main Results:

  • RAPN group showed significantly lower estimated blood loss (EBL) and shorter WIT.
  • RAPN was associated with a higher proportion of malignant lesions.
  • Early renal function (eGFR) was better preserved in the RAPN group.
  • Intra-operative complication rates were significantly lower in the RAPN group.

Conclusions:

  • After adjusting for biases, RAPN demonstrated superior peri-operative outcomes compared to LPN.
  • RAPN also showed better early renal functional preservation.
  • Surgical approach, comorbidity index, tumor complexity, and preoperative CKD stage predict favorable outcomes.
