Which finding would NOT be typical of detrusor overactivity?

• A. Involuntary contractions during filling
• B. Urge incontinence
• C. Normal filling without contractions
• D. Sudden rise in detrusor pressure during filling

Answer: (C)

Detrusor overactivity is defined by involuntary detrusor contractions occurring during the bladder filling phase, which produces urgency and may lead to leakage. Involuntary contractions during filling are a hallmark finding, and a sudden rise in detrusor pressure during filling reflects those contractions. Urge incontinence typically accompanies a contraction that causes leakage, so it fits as a typical finding as well. Normal filling without contractions, however, shows no detrusor overactivity and is not representative of this condition, making it the correct choice for what would not be typical.
