Diagnostic Value of Voiding Scores of the "International Prostate Symptom Score" and the "Bristol Female Lower Urinary System Symptoms-Short Form" Questionnaires in Women With Voiding Dysfunction

Abstract

Introduction:We aimed to investigate the diagnostic value of International Prostate Symptom Score voiding symptom score (IPSS-VS) and Bristol Female Lower Urinary Tract Symptoms-short form voiding score (BFLUTS-VS) in female patients with urodynamically diagnosed voiding dysfunction. Methods:The medical records of female patients who underwent urodynamic examination between May 2007 and November 2021 for lower urinary tract complaints were retrospectively evaluated. A total of 1858 female patients were included in the study. Patients investigated between 2007 and 2014 were asked to fill the IPSS, and patients investigated after 2015 were asked to fill the BFLUTS-SF. Results:The mean age of the patients was 49.06 0.33 in the IPSS group and 50.02 +/- 0.47 in the BFLUTS group. On the pressure flow study, voiding dysfunction was found in 14.8% (n = 95) in the IPSS group and 15.1% (n = 183) in the BFLUTS group. The area under curve value was found to be 0.58 for IPSS and 0.64 for BFLUTS. Threshold values were found as >9 for IPSS-VS and >4 for BFLUTS-VS. The sensitivity, specificity, false negative, and false positive rates for IPSS-VS were 33.3%, 78.8%, 66.7%, and 21.2%, respectively. The same parameters were 45.5%, 78.9%, 54.5%, and 21.1% for BFLUTS-VS, respectively. Conclusion:The diagnostic performance of both the questionnaires was found to be low for diagnosing voiding dysfunction in female patients according to our data. Therefore, the assessment of the voiding phase in women should not solely rely on the current questionnaires. However, further studies using questionnaires including all voiding symptoms are required.
