Postvoid Residual Urine Volume

A postvoid residual volume of more than 100 ml, or more than one-third of bladder capacity, is considered incomplete emptying. 50 This voiding dysfunction can exacerbate detrusor overactivity, and an overactive bladder constantly stimulated by a residual volume responds with contraction, producing symptoms of urgency and frequency, making anti-muscarinic medications less effective.
