A submucosal bladder stone in a 65-year-old woman

We describe a case of a 65-year-old woman with a submucosal bladder stone with no apparent underlying cause. She presented with lower abdominal pain, dysuria, and a history of recurrent cystitis. Ultrasound and computed tomography of the lower abdomen revealed the presence of lithiasis nearby to the left ostium. During ureterorenoscopy, stone was found neither in the bladder nor in the left ureter. Instead, we observed a macroscopic bulge close to the left ureter. After opening of the mucosa, a stone became visible and could be removed. Mostly, imaging of the calculus was done some time before surgery. During this time interval, it is a possibility that the stone has already passed the urinary tract. Our case illustrates that it is important for each patient to search for the calculus extensively to prevent needless symptoms and investigations.
