SAN FRANCISCO -- Testing pregnant women for de nova urinary leakage at 35 weeks' gestation may provide early identification of those who will later develop clinically significant urinary incontinence due to pregnancy, childbirth, or aging, Janis Miller, Ph.D., said at the annual meeting of the American Urogynecologic Society.
Preliminary results of an ongoing, longitudinal study showed that 11 of 37 pregnant women who were dry on a simple continence test at 20 weeks' gestation leaked some urine on retesting at 35 weeks' gestation. The women who leaked were more likely to continue leaking at 6 and 12 months post partum, compared with women who did not leak at 35 weeks' gestation, said Dr. Miller of the University of Michigan, Ann Arbor.
All women kept 3-day voiding diaries, answered an investigational Leakage Index Questionnaire, and were tested using a standing stress test with full bladders (volumes 150-400 cc). In the test, a paper towel was held under them to detect small amounts of urinary leakage upon coughing. None showed any evidence of leakage at 20 weeks' gestation.
Those who developed objectively demonstrable leakage on retesting at 35 weeks scored significantly higher on the eightpoint Leakage Index Questionnaire at 35 weeks and at 6 and 12 months post partum, compared with those who didn't leak at 35 weeks.
