Hypothesis / aims of study To determine whether it is possible to predict urodynamic stress urinary incontinence (uSUI) in women with minimal diagnostic evaluation. Study design, materials and methods Medical records of 2643 female incontinent patients were reviewed and 301 women were eligible for this study. The positive predictive values (PPV's), sensitivity, specifity, and negative predictive values (NPV's) for uSUI and uSUI with or without detrusor overactivity (DO), and DO patients of pure

... SUI symptom (Group 1), combination of pure SUI symptom and positive provocative stress test (+PST) (Group 2) and combination of pure SUI symptom, +PST and absence of overactive bladder (OAB) symptoms (Group 3) were calculated for each group. Results Mean age was 51.03 years (22-88). PPV's, sensitivity, and specifity values for uSUI with or without detrusor overactivity of Group 3 were 100, 7.4, and 100%, while these values for pure uSUI were 93.3, 9.3, and 99.3% respectively. Interestingly, none of the patients in group 2 and 3 had DO. Interpretation of results It seems that it is possible to predict urodynamic stress urinary incontinence in women with minimal diagnostic evaluation. Concluding message Our results showed that it was possible to predict uSUI with high accuracy rates by using minimal diagnostic evaluation in a group of female patients with pure stress incontinence symptoms and +PST while it was also possible to eliminate DO accurately in this group of patients.
