[Validation of urgency scale to detect and assess urgency in patients with overactive bladder].

INTRODUCTION: Urinary urgency is a hallmark symptom of overactive bladder (OAB). Several scales have been used to measure urgency. Taking into account the exceptional importance of these scales, it is important to determine their reliability, which depends directly on the accuracy of the wording and clarity to patients.

AIM: To determine reliability of Russian-language translation of the Patient Perception of Intensity of Urgency Scale (PPIUS) in identifying and assessing urgency in patients with OAB.

MATERIALS AND METHODS: The study included 50 patients (46 women and 4 men) aged 19 to 70 years (mean age 56.5 years). At the time of entering the study, all patients had symptoms of OAB and received anticholinergic therapy for at least 3 months with any drug approved for the use in Russia. PPIUS scale validation was performed by assessing reliability, absence of "habituation" effect of and indicators of convergent, divergent, and content validity.

RESULTS: The Russian version of voiding diary with PPIUS scale was found to have good psychometric properties and besides the content validity also had significant signs of convergent and divergent validity.

CONCLUSION: The Russian-language versions of urgency scales PPIUS and TUFS can be considered validated for using in clinical practice and in clinical and non-interventional studies in patients with OAB in Russia.
