Postpartum urinary retention is defined as the inability of a woman to empty her bladder when it is full of urine, occurring in cases of normal birth, assisted birth or cesarean section, also known as post-cesarean urinary retention. This is a dangerous medical condition that needs to be treated immediately to avoid unwanted complications.

Introduction: The majority of women having planned cesarean section receive spinal anesthesia for the procedure. Typically, spinal opioids are administered during the same time as a component of multimodal analgesia to provide pain relief in the 16 – 24 hours period postoperatively.
