Polypoid cystitis unrelated to indwelling catheters: a report of eight patients.

Since polypoid cystitis (PC) is generally caused by indwelling catheter use, in order to evaluate the patients with PC unrelated to a intravesical catheter, a retrospective analysis of the records of the Pathology Department of Turgut Ozal Medical Center was performed and this revealed 8 patients. Mean age of the 2 female and 6 male patients was 48 years (28 to 70). None of the patients had bacterial growth in urine cultures. All cases were diagnosed incidentally by radiologic and cystoscopic examinations in the evaluation of different conditions, such as hematuria, ovarian abscess, bladder carcinoma, erectile dysfunction, neurogenic bladder, benign prostate hyperplasia and unexplained dysuria. At the beginning, all patients were diagnosed mistakenly as bladder carcinoma. The definitive diagnosis was made after histopathologic examinations of transurethrally resected specimens. Patients were followed for 6 months to 2 years after first diagnosis. No recurrence was established during follow-up. The final urologic examinations which were done currently, were normal. In conclusion, PC is a benign lesion and should be considered in the differential diagnosis of transitional cell carcinoma of the bladder.
