Histomorphological evaluation of non-neoplastic lesions of the urinary bladder

Abstract

Aim: The aim of this study is to evaluate the urinary bladder biopsies for non-neoplastic lesions. Materials and Methods: This study includes 41 non-neoplastic bladder lesion cases out of 125 urinary bladder samples received by histopathology laboratories of two medical colleges between October 2017 and January 2020. The samples included transurethral tumor resections and bladder biopsies. Results: In the present study, seventy-two (59%) cases had neoplastic lesions, 29 (24%) cases had non-neoplastic lesions and 12 (10%) cases showed neoplastic in association with non-neoplastic lesions. The most common non-neoplastic lesions encountered were follicular cystitis, chronic cystitis, and hemorrhagic cystitis. Conclusion:In symptomatic lower urinary tract disease, cystoscopy and histopathological evaluation is rewarding in the diagnosis of various non-neoplastic causative lesions. Awareness of these entities facilitates easy diagnosis and differentiation from malignant processes.
