We present the case of a 72-year-oldman who underwent laparoscopic radical cystectomywith 8po Bricker urinary diversion in 2016 for muscle-invasive bladder cancer. During his follow-upswith our stomatotherapist, the patient started to developperistomal granulomas. Our aim is to eliminate the granulomas formed and prevent the appearanceof new lesions by controlling the urinary pH throughthe administration of Lit-Control® pH Down. The useof Lit-Control® pH Down in our patient has succeededin lowering urinary pH, eliminating part of the peristomalgranulomas, and improving urinary parameterssuch as urine odour and colour.
