✦ Synopsis

The voiding pattern and detrusor contractility of patients with objective stress incontinence were compared with those of controls without abnormalities. The voiding pattern of a patient was qualified by estimating the detrusor pressure and the pressure generated by abdominal straining at maximum flow during voiding. Detrusor contractility was represented by the maximum detrusor pressure built up during a successful attempt to interrupt flow during voiding. It appeared that the contribution of abdominal straining during voiding was significantly higher in the stressincontinent group compared with the continent group. Also detrusor contractility was significantly lower in the stress-incontinent group. In light of the higher incidence of inefficient voiding patterns seen in the stressincontinent population and the low detrusor contractility in this group, preoperative urodynamic evaluation including cystometry with pressure flow studies is important for excluding or at least being aware of the possibility of postoperative bladder emptying problems, apart from the need to exclude underlying motor instability.
