A variety of medical conditions share the symptoms of OAB, and it is important to exclude these in the process of diagnosis. Urinary tract infection (UTI) is the most frequent alternative diagnosis. Even in patients considered to have interstitial cystitis, OAB is a high probability of diagnosis due to its insidious onset of irritative symptoms.For these reasons, ICS Terminology Committee stated that the term OAB can be used only if there is no proven infection or other obvious pathology.\n\nIsolating causative organisms through urine culture plays a crucial role, but is likely to reveal a positive result in less than half of patients presenting with irritative symptoms. Even though ordinary bacteria are not cultured from these patients, there is some evidence to suggest that atypical organisms, such as genital mycoplasma, may be associated with OAB symptoms. For example, 48% of patients with chronic voiding symptoms showed positive cultures for Ureaplasma urealyticum and Mycoplasma hominis. In 91% of the patients with positive culture, symptom severity and frequency were improved after treatment. Another evidence for mycoplasmal involvement in OAB symptoms derives from the improvements in symptoms in more than two-thirds of patients complaining of persistent frequency and urgency after the use of doxycyline which is effective against U. urealyticum, M. hominis and Chlamydia trachomatis.\n\nMycoplasmas are the simplest micro-organisms regarded as true bacteria. They are highly pleomorphic parasites of humans and the absence of a cell wall has been used to distinguish mycoplasma and to place them taxonomically in the class Mollicutes.Mycoplasmas are not generally viewed as being highly virulent, although they usually manifest a predilection for particular host tissues, such as the urogenital or respiratory tracts. It is now being recognized that these organisms play a more important role in human infections than was previously thought. Its slow-growing, non-culturable nature enables them to establish chronic infections, resist the effects of antibiotics and protect the organisms against immune system reactivity.Accordingly, for patients presenting with irritative bladder symptoms, and especially whose first culture is negative, a further culture may be indicated to test specifically for Mycoplasma or Chlamydia infection."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
