Bladder stone causing vesicovaginal fistula and migration into the vagina


Bladder stone is a known complication in a neurogenic bladder that can very rarely cause vesicovaginal fistula (VVF). We are presenting the case of a woman in her late 70s, bed bound with progressive multiple sclerosis (MS), who was referred to urology for consideration of suprapubic catheter due to difficulty in managing her indwelling urethral catheter. The ultrasonogram (USG) identified a 4.7 cm bladder stone with right-sided hydronephrosis (HN) and left atrophic kidney. A CT scan later showed that a 5 cm bladder stone has migrated through a VVF into her vagina. She had a cystoscopy and transvaginal retrieval of the stone. Given her performance status and intraoperative finding of a small contracted bladder, it was agreed to manage her VVF conservatively.

To the best of our knowledge, this is the first case of a primary bladder stone migrating into the vagina through a VVF.
