Bladder calculi account for 5% of all urinary system calculi. They are usually seen in older men and occur because of infravesical obstructions such as prostate hyperplasia , neurogenic voiding dysfunction. Infection, foreign bodies, anti incontinence surgery in woman and rarely pregnancy can also be predisposing factors for bladder calculus. But they can be rarely seen in children and young, healthy patiants without any predisposing factors and are called endemic bladder calculi. İn this case report we present a 23 years old man who has endemic giant bladder calculus and on whom we performed cystolithotomy . The stone weighed 102 gr and measured 53x52x43 mm in size. And it was composed of calcium and oxalate. There were no predisposing factors in this giant bladder calculus. The aim of this case report was to emphasize the fact that bladder calculi can develop in young healthy men without any predisposing factors and that it can be diagnosed readily with DUSG and/or urinary tract USG.
