A patient with diabetes and COPD developed postoperative urinary retention

A patient with diabetes and COPD developed postoperative urinary retention. Which of the following drugs can be used for short term treatment to relieve the symptoms of this person?

A. Bethanechol

B. Methacholine

C. Terazosin

D. Tamsulosin

A. Bethanechol

Explain:- Bethanechol is a preferred drug in the treatment of postpartum and postoperative nonobstructive urinary retention, and it also can counteract bladder dysfunction often seen with phenothiazines and tricyclic antidepressants. It can afford symptomatic relief in congenital megacolon and gastroesophageal reflux but is rarely used for these.
