This article describes two cases of fatal complications of urolithiasis. The first case discusses the development of fatal urosepsis in a patient with a known mental health issue. The patient had self-introduced a thermometer into her bladder, which led to stone formation around the thermometer and consequently to fatal urosepsis. The second case deals with a motor vehicle accident in which a passenger with pre-existing hydronephrosis suffered a kidney injury leading to fatal bleeding into the surrounding adipose tissue. To provide a wider context, the paper also discusses the fatal complications and origin of urolithiasis.
