Background: Bladder urinary calculi occur in 3%-8% of men with bladder outlet obstruction, and although most of them are composed of calcium, in a few cases uric acid bladder stones are diagnosed. Case Presentation: We present clinical images and therapeutic management of a 65-year-old diabetic man with significant prostate enlargement and >30 bladder stones, the largest being 17 mm. Despite the large stone burden, the patient was managed by cystolithotripsy. Remarkably, stone composition analysis revealed 100% uric acid stone. Intraoperative and postoperative course were uneventfully. Conclusion: Uric acid bladder stone pathogenesis seems to be multifactorial with local and systemic factors contributing in different manners and even large stone burdens may be cystoscopically managed.
