Pre-operative factors that predict trifecta and pentafecta in robotic assisted partial nephrectomy

To prospectively evaluate factors that predict achievement of trifecta and pentafecta following robotic-assisted partial nephrectomy (RAPN). Clinical variables of 330 RAPNs performed for a single renal tumor were analyzed for association with post-operative trifecta and pentafecta achievement. Trifecta was defined as warm ischemia time (WIT) ≤ 25 min, negative surgical margins, and no post-operative complications ≥ Clavien grade 3. Pentafecta was defined as trifecta criteria plus > 90% preservation of estimated glomerular filtration rate (eGFR) and no stage upgrade of chronic kidney disease from pre-operative up to 12 months post-RAPN. After adjustment for multiple testing, p
