Intravesical foreign body-induced bladder calculi resulting in obstructive renal failure.

Author information

Division of Urology, Department of Surgery, University of Ottawa, Ottawa, Ont. and the.


We report the case of a 30-year-old man who presented with obstructive renal failure and urosepsis due to bladder outlet-obstructing bladder calculi that formed around 3 copper wires that were self-inserted into his urinary bladder 15 years previously. We present the evaluation, imaging and management of the unique complications resulting from the self-insertion of an intra-vesical foreign body. Our patient's case was unique for 2 reasons. First, the length of time (15 yr) from foreign body insertion to presentation is the longest interval reported in the literature. Second, this is the first report of bladder calculi induced by the insertion of a foreign body that resulted in obstructive renal failure.
