Which symptom might indicate a complication in a postoperative patient after abdominal surgery?

Decreased urine output can indicate a potential complication in a postoperative patient after abdominal surgery. This symptom may suggest issues such as dehydration, impaired kidney function, or urinary retention disorders, especially following certain types of abdominal surgeries that could impact the urinary tract or affect fluid balance. Monitoring urine output is crucial in the postoperative setting as it can provide valuable information about the patient's hydration status and kidney perfusion. A significant reduction in urine output could be an early signal of complications such as acute kidney injury or the body experiencing a stress response to surgery. Recognizing and addressing decreased urine output promptly can significantly impact the overall recovery and outcome for the patient.
