Objective:
To develop and validate a prediction model for bothersome stress urinary incontinence after prolapse surgery and to compare it with an existing clinical prediction model (CUPIDO model).
Design:
Retrospective cohort study.
Setting:
Two tertiary hospitals in South Korea.
Population:
A total of 1142 patients who underwent prolapse surgery with or without a concomitant midurethral sling.
Methods:
To construct a prediction model, we performed logistic regression using both exhaustive and stepwise variable selection, validating the model both internally and externally.
Main Outcome Measures:
Bothersome stress urinary incontinence defined as the presence of bothersome symptoms of stress urinary incontinence and/or subsequent continence procedure one year after surgery.
Results:
Postoperative bothersome stress urinary incontinence occurred in 10% of patients. A model containing six predictors (age, diabetes mellitus, subjective urinary incontinence, prolapse reduction stress test result, type of prolapse surgery, and a concomitant midurethral sling) showed excellent performance for predicting bothersome stress urinary incontinence (area under the curve 0.74, 95% confidence interval 0.62-0.86) and outperformed the CUPIDO model (area under the curve 0.63, 95% confidence interval 0.49-0.76; DeLong's test P = 0.014).
Conclusions:
This prediction model might be a useful tool to guide patient decision making regarding a concomitant continence procedure at the time of prolapse surgery. The predictive value of this model needs to be validated further in cohorts with different characteristics.
Tweetable Abstract:
The proposed prediction model for bothersome stress urinary incontinence after prolapse surgery outperforms an existing model.
