[Urodynamic analysis of postoperative urinary incontinence in women. Apropos of 40 cases of incontinence recurring after treatment for incontinence or secondary to treatment for prolapse].

40 cases of recurrent incontinence after cure of incontinence or secondary to cure of a prolapse were investigated 6 months or more after the initial operation by means of uroflowmetry, cystometry and resting and stress urethral profile. A hyperactive bladder was observed in 20 per cent of cases, 50 per cent of cases presented sphincter incompetence and 75 per cent had a defect of transmission. In 37 per cent of cases, the post-operative incontinence was due to persistent defect in transmission and required a second operation, while in 40 per cent of cases, the cause of this incontinence was complex and required medical treatment associated with re-training. 2 cases of incontinence were also associated with severe disorders of micturition. Urodynamic investigations appear to be essential for the analysis of the frequently complex problem of post-operative incontinence. When compared with the pre-operative data, they provide a better understanding of the mechanism of action of each type of operation and guide the surgical indications.
