5 Must Know Facts For Your Next Test

1. Urinary retention can be caused by medications such as anticholinergics, which inhibit bladder contractions.
2. Chronic urinary retention may require catheterization to manage symptoms and prevent complications.
3. Acute urinary retention is a medical emergency that often requires immediate catheterization to relieve bladder pressure.
4. Urinary antispasmodics like oxybutynin are used to treat conditions that cause spasms in the bladder muscles, potentially leading to urinary retention.
5. Diagnosis of urinary retention often involves measuring post-void residual volume using ultrasound.
