RICCI ARRIOLA, P.; SOLA DALENZ, V.  y  PARDO SCHANZ, J.. Occult stress incontinence identify by preoperative urodynamic study in women with severe pelvic organ prolapse. Actas Urol Esp [online]. 2008, vol.32, n.8, pp.827-832. ISSN 0210-4806.

Objective: To review the effectiveness of preoperative urodynamic study made with correction of the severe genital prolapse by Bresky valve in the diagnosis of urinary occult incontinence, in order to plan a correction with a prophylactic sub-mid urethral mesh in the prolapse surgery. Patients and Method: Patients of the Urogynecology and Vaginal Surgery Unit of Las Condes Clinic, between January 2006 and December 2007, with grade III or IV cystocele. A condition was patients without previous prolapse and/or incontinence surgeries. A non multichannel urodynamics test was made with prolapse correction by a Bresky valve. The urethra retro resistance measurement and cystometry was made. In the women in whom the occult urinary incontinence was discards the prolapse surgery was made with Prolift mesh. In the women with occult incontinence a prophylactic sub-mid urethral tape was applied in the prolapse surgery, to avoid the appearance of incontinence after surgery. Results: Thirty eight women fulfilled the criterion to enter in this study, 14 (36,8%) of them did not register occult urinary incontinence in the urodynamic test. In the 24 (63.2%) with occult incontinence: Type I in 1; type II in 2; type III in 1 and type II+III in 10. During the cystometry 3 of them registered an asymptomatic hyperactive detrusor. In 1 (4.2%) of the 24 patients with prophylactic incontinence surgery, in the immediate postoperative time a failure was observed. The rest 23 women did not present incontinence during the observation period between 4 to 24 months. In the 14 women only with prolapse surgery incontinence was not registered. Conclusions: The preoperative urodynamic test with correction of severe genital prolapse by Bresky valve is an efficient method to detect the occult urinary incontinence. This allows planning a prophylactic incontinence surgery. According to our experience this method is safe and effective to avoid that the occult incontinence appears after a severe cystocele surgery repair and allows to given an integral solution to the pelvic floor problems that frequently sees associate, because they risk factors are the same to these conditions and both cause a high degree of deterioration of quality of life.
