We present a case of a bladder stone which formed on the intravesical portion of tension free vaginal tape material secondary to bladder perforation. 8 years previously, a tension free vaginal tape (TVT) operation was performed. The patient was referred to hospital with persistent urinary infection and urinary incontinence. An intravesical stone that had formed on the TVT sling material was detected by cystoscopy and it was removed with the sling material by a supra pubic cystostomy approach. When evaulating patients presenting with urinary symptoms after a TVT procedure, bladder complications should be kept in mind.
