Corynebacterium D2, a saprophytic microoganism of skin, causes alkaline encrusted cystitis in patients with a previous bladder injury. In 5 patients that had presented this nosological entity, these gram-positive rods were isolated in urine cultures and calculi. Four patients had undergone urological instrumentation maneuvers and one patient (female) had a history of recurrent cystitis from gram-negative bacteria. Corynebacterium D2 grows slowly and under certain conditions, as those described above, must be considered pathological despite counts of less than 100,000/ufc-cc. It is ureolytic and highly resistant to antibiotics. The synergistic effects of antimicrobials, acetohydroxamic acid and transurethral resection of the lithiasic plaques achieve satisfactory treatment of alkaline encrusted cystitis from Corynebacterium D2.
