Is There Any Difference Between Questionnaires on Pediatric Lower Urinary Tract Dysfunction?

OBJECTIVE To investigate the diagnostic properties of 3 different scoring systems (Dysfunctional Voiding Symptom Score [DVSS], Dysfunctional Voiding and Incontinence Symptoms Score [DVISS], Incontinence Symptom Index-Pediatric [ISI-P, for children older than 11 years]) that are used to evaluate lower urinary tract symptoms in pediatric population. MATERIALS AND METHODS Eighty-four participants were evaluated by detailed history, physical examination, 3 different scoring systems (DVSS, DVISS, ISI-P), ultrasonography, and uroflowmetry. Depending on the tests, cases were stratified as healthy or lower urinary tract symptoms (LUTS) by 2 urologists who were blinded to the questionnaires. Patients were reevaluated by the same tests and questionnaires 3 months after treatment. Diagnostic properties of questionnaires were calculated. Additionally, parents were asked to scale the improvement of symptoms subjectively from 0% to 100% to correlate to each of the three scoring systems. RESULTS The mean ages of the normal and the LUTS groups were 9.1 +/- 2.6 years and 10.1 +/- 2.8 years, respectively (P =.301). Gender (male: female) distribution was 21: 21 in the LUTS group and 25: 17 in the control group (P =.381). In terms of diagnosis, DVISS has the highest accuracy (sensitivity: 81%, specificity: 97.6%, accuracy: 89%) followed by ISI-P (sensitivity: 55.6%, specificity: 100%, accuracy: 82%) and DVSS (sensitivity: 54.8%, specificity: 97.6%, accuracy: 76%). The similar order was valid for the 23 patients older than 11 years (accuracy for DVISS: 87%, for ISIP: 82%, and for DVSS: 78%). In terms of response to treatment, all 3 tests showed good correlation with parents' ratings (DVSS: P <.001, DVISS: P =.005, ISI-P: P =.042). CONCLUSION Although DVISS had the highest accuracy in distinguishing the patients from healthy controls, all 3 questionnaires seem to be equivalent for the evaluation of response to treatment.
