Robot-assisted partial nephrectomy (RAPN) is emerging as a viable approach for nephron-sparing surgery (NSS), though many reports to date have been limited by evaluation of a relatively small number of patients.
We present the largest multicenter RAPN experience to date, culling data from four high-volume centers, with focus upon functional and oncologic outcomes.
Design, setting, and participants
A retrospective chart review was performed for 183 patients who underwent RAPN at four centers between 2006 and 2008.
RAPN was performed using methods outlined in the supplemental video material. Though operative technique was similar across all institutions, there were minor variations in trocar placement and hilar control.
Perioperative parameters, including operative time, warm ischemic time, blood loss, and perioperative complications were recorded. In addition, we reviewed functional and oncologic outcomes.
Results and limitations
Mean age at treatment was 59.3 yr. Mean tumor size was 2.87
RAPN is a safe and efficacious approach for NSS, offering short ischemic times, as well as perioperative morbidity equivalent to other standard approaches. Moreover, RAPN is capable of providing patients with excellent functional and oncologic outcomes.
