Bladder stone formation after a tension-free vaginal tape procedure: report on two cases.

We present 2 cases of large bladder stones formed on a tension-free vaginal tape (TVT) which was inadvertently passed through the bladder during the continence procedure. The stones together with the intravesical portion of the slings were removed using a suprapubic approach. High clinical suspicion of bladder complications is necessary when evaluating patients with urinary symptoms after a TVT operation.
