What type of incontinence is caused by a physical blockage or obstruction in the urinary tract?

Overflow incontinence occurs when a physical blockage or obstruction in the urinary tract prevents proper bladder emptying, leading to an overfilled bladder that leaks urine. This condition can be caused by various factors such as enlarged prostate, bladder stones, or strictures that restrict urine flow. As a result, the bladder becomes distended and cannot effectively manage normal urinary output, resulting in involuntary leakage.

Functional incontinence refers to the inability to reach the bathroom in time due to physical or cognitive impairments, not directly caused by a blockage. Stress incontinence is related to during involuntary leakage of urine when there is an increase in abdominal pressure, like during coughing or exercise, and not due to an obstruction. Mixed incontinence is a combination of different types, such as stress and urge incontinence, but it also does not specifically relate to urinary obstruction. This distinction is critical in understanding the underlying causes of different types of urinary incontinence and managing them appropriately.
