ABSTRACT
Overactive bladder (OAB) syndrome is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence (UUI), in the absence of urinary tract infection (UTI) or other obvious pathologies [1]. Thus, oab is a clinical diagnosis derived from a symptom complex centered on urinary urgency and does not require confirmatory urodynamic evaluation. Strictly speaking, "frequency" is simply the number of times someone passes urine in a defined time period; the relevant oab symptom of passing urine too often by day is "increased daytime frequency (IDF)," and this would been more appropriate phrasing in the definition [2]. An alternative name for oab is urgency syndrome [1].
