Beyond immediate bladder distress and renal risks, male patients frequently question whether urinary retention and its underlying etiologies impair erectile capacity, seminal emission, and overall reproductive health. 1. What Are Acute and Chronic Urinary Retention? Mechanisms and Definitions Urinary...

Combining mirabegron with an antimuscarinic agent offers an effective, synergistic pharmacological approach for men suffering from persistent overactive bladder (OAB) symptoms and lower urinary tract symptoms (LUTS) that do not adequately respond to monotherapy. By concurrently targeting beta-3 adrenergic receptors to enhance detrusor relaxation and blocking muscarinic receptors to inhibit involuntary bladder contractions, this dual-mechanism...

Mirabegron is a selective beta-3 adrenergic receptor agonist (β3-agonist) primarily indicated for the treatment of overactive bladder (OAB) symptoms, including urgency, frequency, and urge urinary incontinence. In men, mirabegron works by binding to beta-3 receptors located on the detrusor muscle of the bladder, promoting smooth muscle relaxation during the storage phase without impairing bladder contraction...

The 24-hour urinary free cortisol test is a quantitative laboratory assessment measuring the total amount of cortisol hormone excreted in the urine over a full 24-hour day-and-night cycle. It serves as an essential diagnostic tool for physicians to evaluate adrenal gland function and screen for disorders related to hormonal imbalance within the body. 1. Definition...
