Risk factors & associated complications for postoperative urinary retention after lumbar surgery for lumbar spinal stenosis

Postoperative Urinary Retention (POUR) is a very common post-operative complication of all surgeries (5 – 70%) that may lead to complications such as urinary tract infection (UTI), bladder over-distention, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence of POUR is highly variable (5.6 – 38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size is a major limitation of available studies concerning POUR following spine surgery that may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences.
