Postoperative Urinary Retention

💡 What is Urinary Retention?

Urinary retention means the bladder contains urine, but the person is unable to empty it properly. In simple words: the urine is there, the bladder is full, but the patient cannot pass it.

The word urinary comes from the Latin word urina, meaning urine. The word retention comes from the Latin retinere, meaning “to hold back” or “to keep.” Therefore, urinary retention literally means urine being held back in the bladder.

🔍 Why does this happen after surgery?

Urinary retention is a common postoperative problem, particularly after abdominal, pelvic, or other major surgeries. Several factors can temporarily interfere with normal bladder emptying.

• Anesthesia: General or regional anesthesia can temporarily reduce bladder sensation and the normal contraction of the bladder.
• Opioid pain medicines: These medicines can reduce the normal urge and ability to empty the bladder.
• Pain: Pain and discomfort can interfere with normal urination.
• Reduced mobility: The patient may have difficulty getting up and going to the toilet.
• IV fluids: Large amounts of fluid given during or after surgery can increase urine production.
• Bladder dysfunction: Temporary disturbance of the nerves controlling the bladder can make emptying difficult.

🩺 Understanding the Important Signs

The most important clues in this patient are:

Suprapubic means the area located above the pubic bone. “Supra” means above, while “pubic” refers to the pubic bone. When the bladder becomes very full, it can expand upward and become palpable in the lower abdomen.

A normal bladder stores urine and contracts when it is time to empty. During urinary retention, the bladder continues filling, but effective emptying does not occur. As urine accumulates, the bladder becomes increasingly distended and uncomfortable.

🧠 A Simple Way to Remember

👩‍⚕️ Important Nursing Points

• Assess the patient’s ability and urge to void after surgery.
• Observe for suprapubic fullness, discomfort, and bladder distension.
• Monitor urine output and the time since the last void.
• Review medications, especially opioids, and the type of anesthesia used.
• Provide privacy and an appropriate position for urination when possible.
• If retention is suspected, assess bladder volume according to facility protocol, often using a bladder scanner.
• Significant retention may require catheterization as prescribed or according to protocol.
