To locate preoperatively continent women with pelvic organ prolapse at risk of developing incontinence after surgery by means of reducing the prolapse preoperatively with a speculum and a pessary.
Design: Prospective observational cohort study.
Setting: Departments of Obstetrics and Gynecology at Northern Alvborgs County Hospital, Varbergs hospital and Sahlgrenska University Hospital, Sweden between 2000 and 2004.
Population: Patients scheduled for anterior wall repair with no history of incontinence.
Data were collected using a questionnaire, a voiding diary, a gynecological examination including staging of prolapse with the pelvic organ quantification system and clinical testing preoperatively and one year after vaginal repair. The first test included a cough test while the prolapse was reduced with a speculum. The second test was performed with the patient undergoing a standardized quantification test and a 48- hour pad test after reducing the prolapse with a pessary. Postoperatively, clinical testing was repeated one year after surgery without any device in place.
Main outcome measures: Reported symptoms of leakage during movement or coughing.
Seventy-four patients were included. Before surgery six (8.1%) women tested positive during the speculum test and seven (9.5%) during the pessary test. Eight women (10.8%) were found to have subjective urinary stress incontinence after one year. This was only confirmed in 4 women during stress testing. The positive predictive values for subjective stress incontinence of the speculum and the pessary tests were 42.9% (12.0;76.9 95%CI) and 33.3% (-4.4;71.5 95%CI) respectively. The negative predictive values of the tests were 92.5% (90.3;1.00 95%CI) and 91.1% (88.5;99.7 95%CI).
The tested preoperative methods predicting de novo subjective stress incontinence after anterior wall repair did not show sufficient positive predictive values to be clinically useful.
