Small contracted bladders posing bigger problems: Etiology, presentation, and management and a short review of literature

The purpose of this study was to assess various etiologies, diagnosis and management. This rare entity is a neglected condition which should always be under clinical suspicion by broad speciality of practitioners for early treatment. Retrospective data collected from 2018 to 2021 in the All India Institute of Medical Sciences Rishikesh was used. All patients diagnosed with the small contracted bladder in the given period were included. The primary outcome of the study was to find out the common causes, early tests used for diagnosis and management done in the patients of small contracted bladder attending this tertiary care centre. Between 2018 and 2021, a total of 12 patients were diagnosed to have small capacity bladder (SCB). The most common symptom was frequency (75%). On cystoscopy, 33.33% (n = 4) had less than 50 ml and 66.66% (n = 8) had 50-100 ml bladder capacity respectively. 37.5% (n = 3) were diagnosed by urine AFB culture, 62.5% (n = 5) were diagnosed by urine for PCR, 62.5% (n = 5) were diagnosed by radiological investigations. Eight patients (66.66%) underwent surgical treatment in cases diagnosed as tuberculosis like augmentation cystoplasty and supra-trigonal cystectomy. Other rare causes found were eosinophilic cystitis, radiation induced contracture and BCG induced contracture. Small capacity bladder is an unusual condition, with still dilemma on the definition of small capacity and only few literature mentioning the causes, diagnosis and treatment. Even though tuberculosis is a common cause of SCB, still rare causes should always be kept in mind for relieving patient symptoms at the earliest.
