Stopping Anticoagulation Before TURP Does Not Appear to Increase Perioperative Cardiovascular Complications

ObjectiveTo evaluate the impact of stopping anticoagulant medications prior to transurethral resection of the prostate on peri-operative cardiovascular complications.MethodsRetrospective series (305 patients) undergoing TURP at a tertiary hospital between 2006 and 2010. All men were evaluated in preadmission clinics with defined protocols, with a low threshold for cardiovascular investigation. Incidence of postoperative bleeding and cardiovascular and cerebrovascular events was determined for 3 patient cohorts: group A—where anticoagulants were ceased preoperatively; group B—who were not receiving any anticoagulants; and group C—who underwent TURP while taking aspirin.ResultsOf 305 patients, 194 (64%) did not receive anticoagulation therapy, 108 (35%) stopped receiving anticoagulation therapy pre-TURP, and 3 (0.98%) underwent TURP while taking aspirin. Anticoagulants used were aspirin (22.6%), warfarin (4.9%), antiplatelets (4.9%), and combination treatments (3.9%). Incidence of postoperative hemorrhage (early and delayed) was not significant (P = .69) between group A (10/108) and group B (7/194). Transfusion rate was 0.6% (2/305). Overall incidence of cardiovascular events was 0.98% (group A, n = 1 vs group B, n = 2), and incidence of deep vein thrombosis (0.32%; group A, n = 0 vs group B, n = 1) was not statistically significant (P = .30 and P = .37, respectively). Overall incidence of cerebrovascular events (0.65%; group A, n = 1 vs group B, n = 1) was not significant (P = 1.00). There were no deaths.ConclusionMen who have discontinue anticoagulation therapy before TURP do not appear to have a higher incidence of cardiovascular or cerebrovascular events, or bleeding-associated morbidity. It is possible that the morbidity attributed to discontinuing anticoagulation in this population may be overemphasized. Larger prospective studies are needed to better evaluate this clinical problem.
