Predictors of renal function after open and robot‐assisted partial nephrectomy: A propensity score‐matched study

Objective To investigate parameters predicting short‐ and long‐term renal function after open partial nephrectomy and robot‐assisted partial nephrectomy. Methods Medical records of 896 patients who underwent open partial nephrectomy or robot‐assisted partial nephrectomy from 2004 to 2017 at a single large‐volume institution were retrospectively reviewed. Propensity score matching of open partial nephrectomy and robot‐assisted partial nephrectomy group was carried out with a ratio of 1:1. Postoperative outcomes were compared, and multivariate logistic regression was carried out to identify the parameters influencing acute kidney injury and chronic kidney disease progression. Results No significant differences in preoperative characteristics were observed between the two study groups after matching. Robot‐assisted partial nephrectomy was significantly associated with a longer warm ischemic time (P
