Estudio de la incontinencia de orina femenina mediante urodinamia monocanal: Comparación con los síntomas de ingreso. Análisis de 590 mujeres

Abstract

Objectives: To compare the clinical diagnosis of the urinary incontinence with the results obtained by MoniTorr™ urodynamic test. Methods: Prospective study of 590 consecutive patients with symptomatic urinary incontinence, between January 2006 and June 2008, at the Urogynecology and Vaginal Surgery Unit, Obstetrics and Gynecology Department, Clínica Las Condes, Santiago, Chile. Median age was 55 years (Range 30-91 years). In all patients the type of urinary incontinence (stress, mixed or urgency! was classified according to symptoms and signs observed during the first approach. Urodynamic test with a non-multichannel system was performed (retro- re-sistance pressure and cystometry were measured! and incontinence was classified in accordance to the parameters obtained. The clinical diagnoses were compared with the urodynamic test results. Results: In 420 patients with clinical diagnosis of stress urinary incontinence (SUI) urodynamics registered 43 (type 0), 4 (I), 181 (II), 2 (III), 118 (II+III), 21 (0+HD), 26 (II+HD), 3 (III+HD) and 22 (II+III+HD). In 92 with Mixed Urinary incontinence urodynamics registered 17 (0), 16 (II), 20 (II+III), 9 (0+HD), 12 (II+HD), 1 (III+HD) and 17 (II+III+HD). In 78 women with urgency incontinence, urodynamics registered 32 (normal), 2 (I), 5 (II), 5 (II+III), 27 (HD), 3 (II+HD) and 4 (II+III+HD). Conclusions: The non-multichannel MoniTorr test is an objective method to demonstrate the urinary in-continence diagnosed clinically. The urodynamic test is a complementary examination, very useful in the study of urinary incontinence. The clinical diagnosis can be different to objective urodynamic diagnosis. The urodynamic study allows planning the solution adapted for each patient.
