Delivery of huge bladder stone in a thirty-five-year-old man

Abstract

Introduction: Bladder stone is the most common form of lower urinary tract stones and constitutes 5% of all urinary tract stones. The giant bladder stones are very rare and our report was the first one in Iran and in the world.

Case presentation: The patient was a 35-year-old man who was referred to our urology clinic with the lower urinary tract symptoms. Irritative symptoms were dominant without obstructive symptoms. During a physical examination, hard mass was palpated in suprapubic area. On ultrasonography, a huge stone with 110-mm diameter was revealed in the bladder.

Conclusions: A unique point in this patient was the absence of any history or current conditions such as bladder outlet obstruction or foreign body, which might predispose bladder to stone formation. Another unique point was the heavy weight (826 g) of one-piece-stone filling all bladder space. In majority of reported bladder stones, the weight was lower and the stones were in multiple pieces.
