title: Cough transmission ratio: an indicator of suburethral vaginal wall tension rather than urethral closure?
abstract: The significance of cough transmission ratios (CTR) in 6 unoperated and 15 previously operated patients is discussed. It is concluded that CTR is an index of periurethral muscle contractile activity, and vaginal wall tension, rather than urethral closure.
