Which type is associated with leakage caused by bladder overdistention and retention of urine?

• A. Stress Incontinence
• B. Overflow Incontinence
• C. Urge Incontinence
• D. Transient Incontinence

Answer: (B)

Overflow incontinence occurs when the bladder cannot empty fully and becomes overdistended from urine retention. As urine accumulates, intravesical pressure rises. The detrusor muscle may be weak or there is an obstruction preventing complete emptying, so urine gradually leaks around the urethral sphincter, producing leakage or dribbling. This contrasts with other types: stress incontinence leaks with increased abdominal pressure from pelvic floor weakness; urge incontinence leaks from a sudden, strong urge due to an overactive detrusor; transient incontinence is temporary and due to reversible factors like infection or medications. Clinically, you might notice a weak, intermittent stream, hesitancy, a palpable distended bladder, and a high post-void residual volume, which all point to retention-driven overflow as the cause of leakage.
