Abstract

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.

Highlights

Introduction and BackgroundBladder urinary calculi are usually secondary to bladder outlet obstruction (BOO) in men, and lower urinary tract symptoms are commonly associated with BOO, bladder stones develop only in 3%–8% of cases.[1]
