[INTRAVESICAL MIGRATED SUTURE AFTER LAPAROSCOPIC SACROCOLPOPEXY SUCCESSFULLY TREATED BY TRANSURETHRAL AND TRANSVESICAL SURGERY : A CASE REPORT].

A 68-year-old woman presented to a local physician with lower abdominal pain. Urinary bladder stones were identified, and the patient was referred to our department. She had undergone laparoscopic sacrocolpopexy (LSC) for uterine prolapse 2 years ago. Transurethral cystolithotripsy (TUCL) was performed, and a suture was found in the stone arising from the posterior bladder wall. We speculated that the suture migrated into the urinary bladder after LSC and formed a bladder stone. The sutures could not be removed transurethrally using a laser. A nephroscope was employed to attempt suture division using laparoscopic scissors ; however, the suture remained difficult to grasp or cut. The second surgery was performed using a transurethral nephroscope and a transvaginal laparoscopic trocar. The suture was grasped using forceps inserted through the trocar and excised through a nephroscope using scissors. No postoperative complications or recurrences were observed. Combined transurethral and transvesical approaches are useful for treating foreign bladder bodies that require grasping for removal.
