Efficacy and Safety of Catheter Interventions for Postoperative Urinary Retention After Primary Hip and Knee Total Joint Arthroplasty.

Before discharge, we observed equivalent resolution rates and equivalent time to resolution for indwelling and intermittent catheterization alone without compromising patient safety. Intermittent catheterization is favored, however, because in situ catheter exposure is dramatically reduced and postdischarge complication rates are lower. Additional research is needed to develop evidence-based POUR guidelines for outpatient TJA.
