B-PO05-203 RISK FACTORS FOR POSTOPERATIVE URINARY RETENTION IN PATIENTS UNDERGOING ATRIAL FIBRILLATION ABLATION

Abstract

BackgroundPatients undergoing atrial fibrillation (AF) ablation often undergo bladder catheterization to alleviate retention. However, it is associated with increased complications, increased length of stay and recurrent hospitalization. Identification of risk factors for retention may help prevent bladder catheterization and its complications.ObjectiveTo determine the risk factors for postoperative urinary retention (POUR) in patients undergoing AF ablation.MethodsIn a single-center, retrospective study all cases of POUR requiring urinary catheterization during January 1 to December 31, 2020 matched to age, and gender controls (n=56) were analyzed. POUR was defined as inability to void, or symptoms with high post void residuals>400ml, requiring bladder catheterization.ResultsPrevalence of benign prostate hypertrophy (BPH) was 61% in cases and 18% in controls (p=0.001). Preoperative alpha blocker use was 50% vs 21% (p=0.026). Of cases, 24% with BPH were not on an alpha blocker. In multivariable adjusted analysis, BPH [OR 13.7 (95% CI 1.7, 111, p=0.01)] and post-op diuretic use [OR 18.2 (1.7, 199, p=0.02)] were significantly associated with POUR. There was no difference in 30-day readmissions, but length of hospital stay was longer in cases (1±0.47) than in controls (0.3±0.52, p<0.001). Analgesic medications, intra-operative anesthetic agents, and procedure duration did not significantly affect POUR, Table 1.Conclusion BackgroundPatients undergoing atrial fibrillation (AF) ablation often undergo bladder catheterization to alleviate retention.
