[Value of the Q-tip test in patients with urinary incontinence]. / Valor de la Prueba del Hisopo en pacientes con incontinencia urinaria.

ABSTRACT

We evaluated the accuracy of the Q-tip test to measure uretrhovesical junction mobility in patient's histories of urinary incontinence, and pelvic relaxation. A retrospective study of 183 files of patients with urinary incontinence and anterior vaginal wall relaxation in the Instituto Nacional de Perinatología (INPer) between march 1994 and may 1995. All patients underwent a systematic diagnosis evaluation with detailed history and physical examination including Q-test, neurology examination, urinary, urine culture, uretrhoscopy and urodinamic studies. We correlated Q-tip test pelvic relaxation to measure urethrovesical junction mobility. They were placed in three groups. Group I formed by stres incontinence, group II formed by mixed incontinence and group III formed by recurrent incontinence. Mean age 46.3 years (29-72), almost all the patients were multiparas, menopausal status in 72, with hormonal treatment 48. Q-tip test was not different between the groups. Group I had cystocele II with hipermobility statistically significant difference, the same in group II. No differences were found in the group III. We concluded that urethral position and mobility as measure by the Q-tip test are related to defects in interior vaginal support, but not to specific urologic diagnosis.
