<unk>  is defined as an inability to pass urine, or incomplete emptying of the bladder. It is one of the most common presenting complaints encountered in the emergency department, and can be acute or chronic. It is commonly seen in males as compared to females due to benign prostate hyperplasia. If undiagnosed or left untreated, this condition can be life-threatening as it may lead to kidney damage and severe urosepsis. Acute<unk>  can be extremely uncomfortable, and is initially managed by urethral or suprapubic  catheterization. Chronic<unk>  is often asymptomatic,  not easily identified, and is linked to increased post void residual volume. A complete detailed history about current prescription, over the counter and herbal medications is necessary along with focused physical examination that must include neurological evaluation.
