Incidence and clinical predictors of postoperative urinary retention following total hip and total knee arthroplasty: A single-center, prospective study.

OBJECTIVES: This study aims to evaluate the incidence and clinical predictors of postoperative urinary retention (POUR) following total joint arthroplasty (TJA) and to evaluate whether preoperative bladder voiding efficiency (BVE) can independently predict POUR. PATIENTS AND METHODS: Between September 2023 and May 2024, a total of 200 patients (66 males, 134 females; median age: 69 years; range, 32 to 90 years) scheduled for primary total hip or knee arthroplasty were prospectively analyzed. Patients were classified into POUR (n=33) and non-POUR (n=167) groups. Demographic characteristics, urological history, operative variables, the International Prostate Symptom Scores (IPSS), and bladder scanner measurements were collected and compared. RESULTS: The overall incidence of POUR was 16.5% (33/200). Compared to the non-POUR group, the POUR group exhibited significantly higher IPSS (p
