Cystic glands metaplasia of the urinary bladder.

Introduction. Cystic-glandular cystitis is one of the varieties of metaplasia of the bladder wall, which, in rare cases, can manifest itself in the form of voluminous polypoid growths. Clinical study. This article presents a case of polypoid changes in the bladder wall due to cystic glandular cystitis in a 74-year-old man against the background of a chronic inflammatory process and achalasia of the upper urinary tract. This observation confirms the theory of the etiological significance for the development of urothelial metaplasia of a long-term persistent urinary tract infection. The only reliable method for diagnosing cystic glandular cystitis and differential diagnosis of pseudotumor changes from urothelial carcinoma is morphological, after transurethral resection. Conclusion. The observation presented in this article showed that the clinical manifestations of cystic glandular cystitis can be variable and require an integrated approach to diagnosis and treatment.
