Stress inconthence and detrusor instability/urge incontinence

The overall incidence of detrusor instability in 603 women with stress incontinence was 30%. One hundred seventy-two women had detrusor instability and/or urge incontinence preoperatively. Twenty-three additional women developed detrusor instability and/or urge incontinence only after operation. By eight weeks after operation 4% of the entire group or 14% of those who had detrusor instability or urge incontinence at any time pre-or postoperatively still had the difficulty with incontinence. These findings indicate that a small number of women with both stress incontinence and detrusor instabilty and/or urge incontinence will still have symptomatic urinary loss as a result of persistent detrusor abnormalities at eight weeks after operation.
