Bladder stones account for 5% of all urinary tract’s stone diseases. They are usually seen in older men because of infravesical obstructions such as prostate hyperplasia and neurogenic voiding dysfunction. Infection, foreign bodies, anti-incontinence surgery in woman can also be predisposing factors for bladder calculus. They can rarely be seen in children and young, healthy patients without any predisposing factors and are then called “endemic bladder calculi”. In this case report we present a 43 year old woman who has had an endemic giant bladder calculus and on whom we performed percutaneous cystolithotomy. The stone measured 61x56 mm in size. It was composed of calcium oxalate. In our patient, despite all the researches there was no etiological cause but the patient, had used herbal pills that came from China. The aim of this case report is to emphasize the fact that bladder calculi can develop in middle-aged patients without any predisposing factors.
