MP16-6 - A propensity-score matched comparison of perioperative Outcomes of Robotic Partial Nephrectomy for cT1a < 2 versus > 2 cm renal masses

Saturday, September 22
10:00 AM - 12:00 PM
Location: Room 243

Introduction & Objective :

To perform a single center evaluation comparing the perioperative, pathological and functional outcomes of robotic partial nephrectomy (RPN) for T1a renal masses < 2 cm vs T1a renal masses > 2 cm.


Methods : Propensity score 1:1 matching of queried patients was performed from the institutional RPN database (January 2007 – January 2017) by age, sex, race, BMI, Charlson’s comorbidity Index, smoker status, diabetes, hypertension, hyperlipidemia, ASA score, eGFR, Chronic Kidney Disease stage and RENAL score. 524 patients were analyzed (262 < 2 cm vs 262 > 2 cm). Perioperative, pathological and functional outcomes were evaluated.


Results :

< 2 cm renal masses had significantly lower operative time, blood loss, ischemia time (14.3 + 9.58 vs 21.5 + 9.51 minutes, p < 0.001) and intraoperative transfusions (0 vs 2.7%, p = 0.015). Moreover, superior early renal functional outcome as assessed by eGFR at first postoperative day (83.1 + 21.3 vs 76.6 + 22.0, p = 0.001), higher percentage of parenchymal preservation (89.9 + 9.45 vs 83.6 + 8.20%, p < 0.001) and a trend towards a lower rate of postoperative complications (13.5 vs 19.5%, p = 0.080) were found. Higher percentage of malignancies was found in larger tumors (74.8 vs 85.9%, p = 0.002), but no difference in positive surgical margins was recorded.


Conclusions : RPN tends to be a low morbidity treatment modality for renal masses < 2 cm. Although active surveillance is a common option for such tumors, RPN remains an effective alternative for selected patients.
