Question

A patient with diabetes and COPD developed postoperative urinary retention.

• A. Bethanechol
• B. Methacholine
• C. Terazosin
• D. Tamsulosin

Answer 1

The Correct Option is A

A patient with diabetes and COPD developed postoperative urinary retention. To choose the correct pharmacological treatment, let's analyze the options:

• Bethanechol
• Methacholine
• Terazosin
• Tamsulosin

Postoperative urinary retention occurs when the bladder is unable to empty correctly. To address this, a medication that stimulates bladder contraction is needed.

Bethanechol

Bethanechol is a cholinergic agonist that predominantly stimulates muscarinic receptors to enhance bladder contractions and facilitate urination. It is ideal for relieving urinary retention caused by surgery.

Methacholine

Methacholine is not suitable in this context as it is mainly used for diagnosing bronchial hyperreactivity.

Terazosin

Terazosin is an alpha-blocker primarily used for treating benign prostatic hyperplasia and hypertension. It helps relieve urinary symptoms from prostatic issues, not directly from postoperative retention.

Tamsulosin

Similar to Terazosin, Tamsulosin is an alpha-1 antagonist used to improve urinary flow in patients with prostate enlargement. It's not the preferred choice for postoperative urinary retention unrelated to prostate issues.

In summary, Bethanechol is the appropriate choice for treating postoperative urinary retention in this case.
