Treatment of the unstable bladder with propantheline and imipramine.

This study shows propantheline and imipramine to be effective in the management of the unstable bladder. It emphasizes the need for urodynamic studies for the accurate diagnosis of urinary incontinence. Comparisons have been made of the efficacy of propantheline and imipramine in various groups of incontinent women and indicates that in appropriately selected groups the 'cure' rate is over 70% but if sphincter weakness is excluded, urodynamics cannot differentiate between those women with unstable bladders who will respond to this medication and those who will not.
