Can de novo stress incontinence after anterior wall repair be predicted?

OBJECTIVE: 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. METHODS: 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. RESULTS: 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 1 year. This was only confirmed in four women during stress testing. The positive predictive values for subjective stress incontinence of the speculum and the pessary tests were 42.9% (95%CI 12.0-76.9) and 33.3% (95%CI -4.4 to +71.5), respectively. The negative predictive values of the tests were 92.5% (95%CI 90.3-1.00) and 91.1% (95%CI 88.5-99.7). CONCLUSIONS: 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.

Hysterectomy and incontinence: a study from the Swedish national register for gynecological surgery.

BACKGROUND: Hysterectomy is one factor that has been suggested to be a risk factor for developing stress incontinence. In Sweden, with a population of 8.86 million, a national register was set up in 1997 in order to have data for assessing the quality of gynecological surgery for benign disorders. METHODS: Data in the Swedish national register for gynecological surgery during the period 1997-2002 were investigated. Surgical methods compared during this time period were: total hysterectomy (abdominal/laparoscopic, n=198/116), subtotal hysterectomy (abdominal/laparoscopic, n=163/86), and total hysterectomy (vaginal/laparoscopic assisted vaginal, n=265/7). Patients who underwent endometrial destruction (endometrial ablation, endometrial balloon treatment, n=187) were used as a control group. Only patients with no preoperative complaints were included. Outcome measures were answers to subjective questions asked pre- and postoperatively regarding urinary problems and incontinence. RESULTS: De novo symptoms of stress incontinence, urgency and urgency incontinence, and/or mixed incontinence were noted in all groups. No differences were found among the groups. CONCLUSION: Factors other than hysterectomy should be discussed causing stress incontinence in women.
