Stone formation on a surgical tack migrated to the bladder 7 years after laparoscopic incontinence surgery

Abstract

A 53-year-old woman admitted to our outpatient urology clinic with complaints of dysuria, urgency and recurrent urinary tract infection (UTI). She had undergone an unknown laparoscopic incontinence surgery seven years ago that we considered being burch colposuspension. She had recurrent UTI for more than one year. Plain radiography showed multiple radiopaque helical materials and semi-opacity in bony pelvis. Cystoscopic evaluation revealed a 3 cm stone fixed at the dome of the urinary bladder. Stone was fragmented endoscopically using pneumonic lithotripter. After fragmentation of the stone, three tacks became apparent. The adhered tack was removed with the aid of grasping forceps by a rotation maneuver. It was not possible to remove the embedded tacks and the operation was ended. One month later, the patient underwent cystoscopy. The bladder mucosa was exactly intact and no tack was visible.
