Key clinical point: The short-term oncological and functional outcomes for partial nephrectomy are comparable for laparoscopic partial nephrectomy following selective embolization of tumor (LPNE) in a hybrid operating room and robot-assisted partial nephrectomy (RAPN). A longer follow-up and a larger cohort of patients would be necessary to verify the benefits of LPNE, which appears to be a very interesting alternative to RAPN.
Major finding: There was no difference between oncological and functional outcomes, with a positive surgical margins (PSM) rate of 4.4% for the 57 patients who had LPNE and of 10.3% for the 48 patients who had RAPN (p=0.32). Further, the mean change in estimated glomerular filtration rate (eGFR) at 1 month was -5.5% for LPNE and -8.3% for RAPN (p=0.17). The mean operative time was shorter in the LPNE group (150 vs 195 min, p less than 0.001), and mean estimated blood loss was less in the LPNE group (185 vs 345 mL, p=0.04).
Study details: All patients who underwent a LPNE at Angers (France) University Hospital between May 2015 and April 2017, and a RAPN at Diaconesses Croix Saint Simon, Paris, between October 2014 and April 2017, were prospectively included. The functional outcomes were evaluated using the change of estimated glomerular filtration rate (eGFR) at 1 month, and the oncological outcomes were evaluated using the positive surgical margins (PSM) rate.
