Objective: Postoperative urinary retention is a common complication for patients recovering from general anesthesia or invasive surgery near the spinal column. However, no study has systematically reviewed the incidence of postoperative urinary retention for spinal surgeries performed at the cervical, thoracic, or lumbar spinal regions. In this review, we critically analyze and summarize the known literature on the incidence and risk factors associated with postoperative urinary retention after spinal surgery. Methods: A comprehensive literature review was performed at the end of September 2019 within the PubMed database. Results: The average incidence of postoperative urinary retention from nine of the 10 studies was 17.2% with one paper that did not report on postoperative urinary retention incidence. Furthermore, age, male gender, location and history of spinal surgery, duration of surgery, benign prostatic hypertrophy, and Foley catheter were reported as major risk factors for postoperative urinary retention and spinal surgery. Conclusion: Overall, spinal cord and postoperative urinary retention remains a poorly understood area requiring further investigation into the incidence, risk factors, and surgical methods influence postoperative urinary retention and post-operative outcomes. We believe an overview of such data can help revise guidelines for the management of postoperative urinary retention and raise awareness of its prevalence in elderly patients undergoing spinal surgery. Level of evidence: Not applicable for this multicentre audit.
