Robotic-assisted partial nephrectomy: lower morbidity

New findings from the large, multicentre IRON study demonstrate that robot-assisted partial nephrectomy (RAPN) is associated with lower morbidity and similar oncologic and long-term renal function outcomes compared with open partial nephrectomy (OPN).

Dr Alessandro Larcher (Ospedale San Raffaele, Italy) presented the large, non-randomised, comparative, prospective study of clinical outcomes after RAPN or OPN at 9 high-volume European, North American, and Asian institutions [1]. The rationale behind this study was that although RAPN is commonly used, there had been little evidence conclusively indicating that one approach was better than the other.

The researchers prospectively identified patients (n=3,468) diagnosed with a cT1-2 cN0 cM0 renal mass who underwent RAPN (n=2,405) or OPN (n=1,063). Detailed preoperative data concerning the tumours was not documented in this study. Clinical outcomes were collected in a central database. For the purposes o...
