Objective To systematically review the incidence and risk factors of postoperative urinary retention (POUR) in patients undergoing hip or knee arthroplasty, and provide a theoretical basis for medical staff to assess and identify high-risk groups in advance. Methods PubMed, Embase, the Cochrane Library, Medline, China National Knowledge Infrastructure, Wanfang Data, VIP database, and SinoMed were electronically searched from the establishment of the databases to January 2023, for literature on the incidence and risk factors of POUR in patients undergoing hip or knee arthroplasty. Two researchers independently screened studies, extracted data, and assessed study quality. Meta-analysis was performed using Stata 14.0 software. Results A total of 21 articles were included, including 9041 patients undergoing hip or knee arthroplasty. The results of meta-analysis showed that the incidence of POUR in patients undergoing hip or knee arthroplasty was 26% [95% confidence interval (CI) (19%, 32%)]. Age [odds ratio (OR)=1.03, 95%CI (1.00, 1.05), P=0.03], male [OR=2.68, 95%CI (1.72, 4.18), P<0.001], infusion volume [OR=2.17, 95%CI (1.08, 4.35), P=0.030], spinal anesthesia [OR=1.72, 95%CI (1.29, 2.30), P<0.001], history of urinary retention/urethral stricture [OR=1.84, 95%CI (1.35, 2.49), P<0.001], use of analgesic pump [OR=4.73, 95%CI (2.29, 9.78), P<0.001], use of glycopyrronium bromide [OR=2.79, 95%CI (1.53, 5.11), P=0.001] were risk factors for POUR in patients undergoing hip or knee arthroplasty. Conclusions The incidence of POUR in patients undergoing hip or knee arthroplasty is relatively high. Age, male, infusion volume, spinal anesthesia, history of urinary retention/urethral stenosis, use of analgesia pump, and use of glycopyrronium bromide are causes of POUR. It is suggested that medical staff should identify the risk of related factors and take early intervention to reduce the occurrence of POUR.
Objective To systematically analyze the relevant research on the application of preoperative exercise training in the pre-rehabilitation of elderly hip fracture patients, identify the specific content, outcome indicators, and application effects of exercise intervention, in order to provide reference for medical staff to carry out relevant interventions. Methods Computer searches were conducted on domestic and foreign databases such as China National Knowledge Infrastructure, Wanfang Database, China Biomedical Literature Database, VIP, Cochrane Library, PubMed, Embase, Web of Science. The search period was from the establishment of the database to January 2024. The scoping review method was used to screen, summarize, and analyze the included studies. ResultsA total of 10 studies were included, including 3 randomized controlled trial, 1 quasi experimental study, 5 retrospective studies and 1 case report. Preoperative exercise preparation includes completing relevant examinations and providing sufficient pain relief. The types of exercise include adaptive training, resistance training, and aerobic exercise. Monitor the patient’s symptoms, signs, and adverse reactions throughout the exercise process. Outcome measures include physical activity and function, pain, average length of hospital stay, and perioperative complications. Conclusions Preoperative exercise training has a positive effect on elderly patients with hip fracture. Elderly patients with hip fracture should be well prepared for preoperative exercise, based on adaptive training, with resistance exercise as the main focus, while monitoring the patient’s physical signs and adverse events during exercise.
