| Abstract: | Objectives: To analyze our experience with laparoscopic partial nephrectomy (LPN) to detail postoperative adverse events and identify factors that may contribute to adverse surgical outcomes. Complications from LPN result from a variety of factors, both technical and inherent. Methods: Single-center review of 144 consecutive LPN (4 surgeons) performed between November 2002 and January 2008 was conducted. Identified complications were graded using standard reporting criteria. Univariate and multivariate statistical analysis of variables and their association with complication event and blood loss was performed. Results: A total of 39 complications occurred in 29 (20%) cases. Of these, 20 (51%) were urologic and 19 (49%) were nonurologic. Individual adverse events by grade were as follows: grade I, 6 (15.4%); grade II, 19 (48.7%), grade III, 11 (28.2%), and grade IV, 3 (7.7%). No grade V complications occurred. The median tumor size and ischemia time were 2.7 cm and 35 minutes, respectively. Univariate analysis identified increased American Society of Anesthesiologists risk score (odds ratio 2.99, 95% confidence interval [CI] 1.28, 6.94) and ischemia time (odds ratio 1.31; 95% CI 1.00, 1.71) as associated with complication risk. On multivariate analysis, longer ischemia time was associated with increased estimated blood loss (95% CI 3, 57; P = .03). Hospital readmission and reintervention was required in 15 (10.4%) and 9 (6.2%) patients, respectively. Conclusions: Complications from LPN occur in a meaningful proportion of procedures although the majority does not require reintervention and half are not urologic. Increasing ischemia time and American Society of Anesthesiologists score are associated with risk for unfavorable surgical outcomes. © 2010 Elsevier Inc. All rights reserved. |
