Objective To explore factors associated with readmission after nephrectomy procedures using a large national database. Materials and Methods A national surgical outcomes database, the American College of Surgeon-National Surgical Quality Improvement Program registry, was queried for data on all patients undergoing open partial nephrectomy (OPN), minimally invasive (laparoscopic + robotic) partial nephrectomy (MIPN), and minimally invasive radical nephrectomy (MIRN) in 2011 and 2012. Patients undergoing these procedures were identified using the Current Procedural Terminology codes. The primary outcome was unplanned 30-day hospital readmission. A multivariate logistic regression model was constructed to assess for factors independently associated with the primary outcome. Results Overall, 5276 cases were identified and included in the analysis: 1411 OPN (26.7%), 2210 MIPN (41.8%), and 1655 MIRN (31.3%). Overall, the 30-day readmission rate was 5.9% (7.8% for OPN, 4.5% for MIPN, and 6.1% for MIRN). On multivariate analysis, the odds for 30-day readmission for MIPN was approximately 70% that of OPN (P =.012). The odds for 30-day readmission for 2012 was about 80% of that of 2011 (P <.001). History of steroid use and of bleeding disorder and occurrence of postoperative transfusion increase the odds of readmission by approximately 2 (P =.005, P =.038, and P <.001, respectively). A postoperative urinary infection increased the odds of readmission by 5.5 (P <.001). Conclusion Contemporary 30-day readmission rates after nephrectomy procedures are influenced by specific patients' characteristics as well as postoperative adverse events. Moreover, contemporary MIPN seems to carry lower odds of readmission than OPN. It remains to be determined to what extent these findings are influenced by the expanding role of robotic technology.
