An 83-year-old man with benign prostatic hyperplasia and several comorbid conditions presented with irremovable urethral Foley catheter. Plain abdominal X-ray revealed a bladder full of stones. The patient had bilateral hydronephrosis and elevated serum Creatinine level. Open vesicolithotomy was done and more than 720 stones in various shapes and sizes was removed. After removal of stone, Creatinine gradually decreased from 4.9 to 1.8 mg/dL and most of lower urinary tract symptoms were alleviated in the follow-up.
