Abstract:
We present a case of encrusted cystitis with ammonium acid urate calculi. An 88-year-old man was referred to our hospital to determine the cause of hematopyuria. He was a patient at another hospital for treatment of interstitial pneumonia with predonisolone. After admission to our hospital, kidney, ureter, bladder X-ray, computed togography and cystoscopy revealed calcification of about two-thirds of the mucosa of the bladder, and biopsy of the bladder revealed bacterial colonies with inflammation and calcification. Calculographic analysis revealed ammonium acid urate calculi. After treatment with antibiotics and irrigation with solita T1, an acidic solution of pH 3.5-6.5, inflammation and calcification were significantly reduced.
