ABSTRACT
INTRODUCTION:
Studies have reached mixed conclusions on the role of antiplatelet and anticoagulant agents on postoperative complications of partial nephrectomies. This study examines whether preoperative anticoagulation use affected the risk of hemorrhagic complications after partial nephrectomy. MATERIALS ANDMETHODS:
This is a retrospective chart review of all partial nephrectomies performed between 2017 and 2022 at a single institution. For each operation, preoperative data was gathered on whether the patient was on anticoagulation, the type and dose of anticoagulation, and how many days the anticoagulation was held preoperatively. Bivariate analyses for continuous measures were performed using Student's t-tests when there were two comparison groups and ANOVA models when there were more than two comparison groups and Chi-Square tests were used for categorical variables, with Fisher's Exact being used when expected cell counts were small.RESULTS:
In this study, warfarin was held for an average of 5.43 days, clopidogrel was held for an average of 6.60 days, aspirin was held for an average of 7.65 days, and direct oral anticoagulants (DOACs) were held for an average of 4.00 days. There was no significant difference in hemoglobin (Hb) change, rate of intraoperative transfusion, postoperative transfusion, bleeding complication, pseudoaneurysm rate, or additional bleeding processes between patients on prior anticoagulation therapy and those not on therapy. There was no significant difference in intraoperative or postoperative outcomes based on history of aspirin use and continuation of aspirin through the surgery. While estimated blood loss appeared statistically significant initially, this difference was accounted for by the covariates of comorbidities, RENAL score, surgical approach, and type of renorrhaphy. Overall, there was no difference in complication rate based solely on aspirin use or continuation of aspirin through surgery.CONCLUSIONS:
No difference in complication rate of partial nephrectomy was determined to be solely due to prior use of anticoagulation or aspirin use alone with appropriate cessation of anticoagulation preoperatively. Overall, patients on anticoagulation are not at a higher risk of intraoperative or postoperative bleeding complications when undergoing partial nephrectomy.Palavras-chave
