Squamous Metaplasia and Its Management in Non-malignant Bladder Diseases

Objective: To reveal possible associations between non-malignant bladder disease and malignancy by evaluating the pathologic examination results of patients who underwent cystectomy for non-malignant diseases and to suggest a point of view for disease management.
Materials and Methods: Medical records of patients, who underwent cystectomy in our clinic between January 2005 and January 2015 for non-malignant diseases, were examined retrospectively.
Results: A total of 14 patients were included in the study. The mean age of the patients was 58.7±9.3 years. Of the patients eight of them were followed up with interstitial cystitis (IC), five with neurogenic bladder and one with hemorrhagic cystitis. Time from diagnosis to cystectomy was 6.1±5.8 years on average in IC patients, 13.8±9.8 years in neurogenic bladder patients and 10 years in hemorrhagic cystitis patients. No malignancy finding was observed according to the pathologic examination results of the cystectomy specimens. However, either chronic or active inflammation was observed in all the patients. In addition to other pathologies non-keratinized squamous metaplasia was detected in five patients.
Conclusion: Patients with non-malignant diseases should be followed-up with cystoscopy and bladder biopsy as a pre-malign lesion caution. Although cystectomy and urinary diversion are surgery methods with high complication rates, they could be suggested to well-informed patients as treatment alternatives.
