Urinary retention after total joint arthroplasty of hip and knee: Systematic review

Purpose: Postoperative urinary retention (POUR) is a common complication after total joint arthroplasties (TJAs). The POUR is managed with urinary catheterization, which is associated with a risk of urinary tract infection and subsequent periprosthetic joint infection. The purpose of this review was to afford a comprehensive understanding of POUR and its management. Methods: We identified 15 original articles concerning POUR after TJA, which were published from January 2010 to February 2019. The diagnostic method, incidence, risk factors, and management of POUR of the 15 studies were reviewed. Results: The incidence of POUR was ranged from 4.1% to 46.3%. Ultrasound was used for the detection of POUR among the total of the 15 studies. The following factors of old age, male gender, benign prostatic hypertrophy, history of urinary retention, spinal/epidural anesthesia, excessive fluid administration, patient-controlled analgesia, the use of opiates, underlying comorbidities, and poor American Society of Anesthesiologists (ASA) grade were risk factors for POUR. Most of the studies did not use indwelling catheterization during surgery. The POUR patients were managed with intermittent catheterization. The most common volume criterion for bladder catheterization was 400 mL. In inevitable use of an indwelling catheter, it should be removed within 48 h. Conclusions: This review provided an up-to-date guide for the detection and management of POUR.
