MICROANATOMY

Detailed explanation-1: -Chronic urinary retention (CUR) is the accumulation of urine in the bladder that results from incomplete or inadequate bladder emptying. Incomplete bladder emptying is most commonly described and measured as the volume of urine left in the bladder after voiding, also known as the postvoid residual.

Detailed explanation-2: -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-3: -Men are more likely to develop overflow incontinence. This type of urinary incontinence causes a constant urine leak or dribble. Urinary retention due to a bladder obstruction, enlarged prostate or other problem can cause the bladder to get too full and overflow.

Detailed explanation-4: -Sometimes the bladder does not empty all the way. This is called urinary (or urine) retention. Urine might be retained if there is an obstruction or stricture (narrowing) in or around the bladder, or when muscles in or around the bladder are weak.
