ABSTRACT

Encrusting cystitis has been defined as an ulcerated inflammation of the bladder with calcium deposits in the bladder wall. It is an infrequent entity and can often go unnoticed. Identified precipitating factors are alkaline urine with pH above seven, previous bladder damage, urinary infection from ureolytic germs (Corynebacterium D2), and immunodepression. Previous bladder damage is not always demonstrable and it is necessary to rule out malignant process beforehand. Encrusting cystitis treatment includes three fundamental steps: Corynebacterium D2 infection control avoiding fluoroquinolones (76-83% resistance), urine acidification, and calcified plaque resection. The case of a sixty-two-year-old patient with past history of stage Ta papillary transitional cell carcinoma treated with transurethral resection of bladder tumor and intravesical chemotherapy with mitomycin C is presented, who nine months after bladder tumor resection developed calcium plaque adhered to the bladder mucosa at the previous resection site. Transurethral resection of bladder lesions was carried out and definitive histopathological study reported calcic crystal deposit with data of non-specific chronic cystitis resulting in diagnosis of encrusting cystitis secondary to intravesical chemotherapy with mitomycin C.
