Retained Tampon Fragment as an Unusual Cause of Vesicovaginal Fistula

Vesicovaginal fistula (VVF) is an uncommon cause of urinary incontinence (UI). Iatrogenic etiologies, especially abdominal hysterectomy, are most common; however, a minority of VVFs are caused by retained foreign bodies. Objects associated with VVF include intrauterine devices, gauze, pessaries, bottle caps, and sexual aids, but retained tampons or other menstrual products have not been commonly reported.

We present the case of a 53-year-old woman, gravida 0, with no prior pelvic surgery, with 2 months of intermittent UI and hematuria. Although initial diagnostic test results were negative, cystoscopy and vaginoscopy eventually confirmed the diagnosis of VVF associated with a retained foreign body. In the operating room, all debris was removed using vaginoscopy, and the VVF was repaired using a modified Latzko technique. At the patient's 9-week follow-up appointment, she was found to have complete healing of the VVF and resolution of associated symptoms.

This is a case of VVF secondary to a retained tampon fragment. In addition to this uncommon etiology, our patient's presenting symptoms were atypical, leading to a delay in diagnosis and treatment for which vaginoscopy was critical.
