ANATOMY

Detailed explanation-1: -Urinary retention is a condition in which you cannot empty all the urine from your bladder. Urinary retention can be acute-a sudden inability to urinate, or chronic-a gradual inability to completely empty the bladder of urine.

Detailed explanation-2: -Draining the bladder With acute urinary retention, a health care professional will immediately drain the urine from your bladder using a catheter. Removing the urine from the bladder eases your pain and helps prevent your bladder and kidneys from being damaged.

Detailed explanation-3: -The most common cause of urinary retention is benign prostatic hyperplasia. Other common causes include prostatitis, cystitis, urethritis, and vulvovaginitis; receiving medications in the anticholinergic and alpha-adrenergic agonist classes; and cortical, spinal, or peripheral nerve lesions.

Detailed explanation-4: -There are different ways to manage urine retention. Common ways include surgery to repair or strengthen the bladder, using a bladder catheter to drain urine, dilating or widening the urethra (the duct that urine flows through when emptied) called having urethral dilation or stents, and giving certain medications.

Detailed explanation-5: -Infections and swelling This causes it to press on the urethra to block the flow of urine. A urinary tract infection (UTI) can cause swelling of the urethra or weakness of the bladder, both of which can cause urinary retention. Diseases spread by having sex (called STIs) can also cause swelling and lead to retention.
