Giant bladder stone resulting in acute kidney injury; A case report and review of literature.

A giant bladder stone is very rare in adults. We report a case of giant bladder stone causing acute kidney injury in a 23-year-old male, who presented with lower urinary tract symptoms (LUTS) characterized by both irritative and obstructive LUTS. In addition, he also had episodes of reddish urine for the past decade. A non-contrast-enhanced CT scan was used for the diagnosis. Open cystolithotomy was performed and a 500g weighing stone was removed. He developed a superficial surgical site infection which was treated with wound care. He was discharged improved. Improvement in symptoms and serum creatinine was noted on follow-up.
