Bladder stones comprise 5% of urinary tract stones. Generally, they occur in the presence of bladder neck obstruction, urinary tract infections associated with neurogenic bladder and foreign objects. They are more common among men than women. Infection stones comprise approximately 15% of urinary tract stones. A giant bladder stone is a rare finding in contemporary urological practice. The general clinical setting is recurrent urinary tract infections, hematuria and urinary retention. We performed an open cystolithotomy on a mentally impaired patient who had a giant bladder stone. The stone removed weighed 465 grams. There was no evidence of any infravesical obstruction on the cystoscopy performed before the operation or during the operation. The stone consisted of 75% carbonate apatite and 25% struvite. Given that such a stone was found in a mentally impaired patient indicates that infection stones can form without infravesical obstruction.
膀胱结石占尿路结石的5%。一般来说，它们发生于膀胱颈梗阻、与神经源性膀胱相关的尿路感染以及存在异物的情况下。男性比女性更易患膀胱结石。感染性结石约占尿路结石的15%。巨大膀胱结石在当代泌尿外科实践中是一种罕见的发现。其一般临床症状为反复尿路感染、血尿和尿潴留。我们对一名患有巨大膀胱结石的智障患者进行了开放性膀胱切开取石术。取出的结石重达465克。术前或术中进行的膀胱镜检查均未发现膀胱以下梗阻的证据。该结石由75%的碳酸磷灰石和25%的鸟粪石组成。在一名智障患者中发现这样的结石表明，即使没有膀胱以下梗阻，也可能形成感染性结石。
