She involuntarily loses a small amount of urine after experiencing a sudden, painful sensation in the bladder. She wakes up at night several times to urinate, and she sometimes cannot make it to the bathroom in time. She has diabetes mellitus type 2 controlled with insulin and a history of pelvic organ prolapse, for which she underwent surgical treatment 5 years ago. Menopause was 11 years ago. She drinks 4-5 cups of coffee daily. Pelvic examination shows no abnormalities, and a Q-tip test is negative. Ultrasound of the bladder shows a normal postvoid residual urine. Which of the following is the underlying cause of this patients urinary incontinence?? A: Recurrent pelvic organ prolapse, B: Decreased pelvic floor muscle tone, C: Increased detrusor muscle activity, D: Increased urine bladder volumes, E: Decreased estrogen levels,  <response>: This is a patient with urinary incontinence that is characterized by sudden, painful bladder contractions resulting in small amounts of urine leakage. The key findings are:- 60 year old multiparous woman - Urinary leakage for 4 months- Involuntary loss of small amount of urine after sudden, painful bladder sensation- Nocturia - History of diabetes mellitus type 2 and pelvic organ prolapse- Menopause 11 years ago- Heavy coffee consumption- Normal pelvic exam and Q-tip test- Normal post-void residual urine on ultrasoundBased on the sudden, painful bladder contractions and urinary leakage, this is most consistent with urge incontinence. The differential diagnosis includes:- Recurrent pelvic organ prolapse - less likely given normal pelvic exam- Decreased pelvic floor muscle tone - would cause stress incontinence, not urge- Increased urine bladder volumes - not supported by normal post-void residual- Decreased estrogen levels - can cause atrophic changes but less likely to cause urge incontinenceThe most likely cause is increased detrusor muscle activity causing involuntary bladder contractions, consistent with urge incontinence.C: Increased detrusor muscle activity
