Which condition is characterized by an inability to empty a full bladder, causing dribbling?

Overflow incontinence is characterized by an inability to completely empty the bladder, which leads to constant dribbling of urine. This condition often occurs when the bladder is overfilled but the individual lacks the ability to fully void. This can happen due to various reasons, such as weakened bladder muscles, blockages in the urinary tract, or nerve damage that impacts the bladder's ability to contract effectively. As a result, even when the bladder is full, urine may leak out without the person having the urge to urinate, leading to the dribbling effect.

This condition stands in contrast to urge incontinence, which is marked by a sudden, strong urge to urinate, often resulting in involuntary leakage. Stress incontinence occurs when physical activities such as coughing or sneezing place pressure on the bladder, causing leakage. Functional incontinence refers to the inability to reach the toilet in time due to physical or cognitive impairments, rather than bladder dysfunction itself. Understanding the distinctions among these types of incontinence helps clarify why overflow incontinence is the correct answer in this situation.
