[Intravesical administration of estriol in sensory urge incontinence--a prospective study].

Local intravaginal application of oestriol is part of the therapeutical programme of sensory urge-incontinence. The effectiveness of a new method--intravesical administration of 1 mg oestriol versus a placebo--has been proved in a prospective randomised study. 21 patients each were treated over a period of three weeks with oestriol or with the placebo-substance intravesically. The effectiveness of the administered therapy was checked with clinical and urodynamic parameters. The intravesical administration of 1 mg oestriol proved to be efficient and free of side effects in respect of the parameters such as imperative micturition, bladder capacity, of the maximum urethral closure pressure as well as the number of micturitions per diem. The intravesical administration of oestriol may be considered as additional method of therapy for treatment of sensory urge-incontinence.
