Foreign Body, Freely Movable in the Bladder vs. Foreign Body, Attached to the Wall
Left picture: The cause of the symptoms is a foreign body stone of the bladder which was freely movable in the bladder cavity, and the nucleus of which corresponds to the tip of a broken Thiemann catheter. The foreign body is not only the cause of a chronic urinary tract infection with deposits of phosphates, but also of a recurrent hematuria. Right picture: In this case, a foreign body stone attached to the bladder wall is present which has been formed around a thread not suitable for bladder surgery, and was maintaining the symptoms.
Left picture: Stone which has been endoscopically removed and which has a curvature at the top and transversely running indentations. It caused microscopical hematuria and gross hematuria, and a chronic urinary tract infection. The size of the foreign body is the same as in the contralateral picture. Right picture: Endoscopic picture of a stone with an irregular structure which is attached to the bladder wall. It led to recurrent hematuria and urinary tract infections.
