Vesicovaginal Fistula Diagnosed by Contrast-Enhanced Ultrasound:A Case Report
Vesicovaginal fistula ( VVF ) refers to the uncontrolled flow of urine from the vagina due to an abnormal fistula between the bladder and the vagina,which seriously affects the physical and mental health and quality of life of the patient.Timely and accurate detection of the fistula is crucial.Routine transvaginal ultrasound is prone to missing the diagnosis of small fistulas between the bladder and the vagina.Contrast-enhanced ultrasound ( CEUS ) can more clearly and accurately display the location and thickness of fistulas.In this paper,we discussed and analyzed a case of postoperative cervical cancer and bladder tumor in the First Medical Center of the General Hospital of the People' s Liberation Army.The patient presented with urinary incontinence and persistent transvaginal leakage with urine loss.Routine transvaginal ultrasound suggested the possibility of VVF due to localized stenosis in the mid-vagina and the rectum,which made it impossible to place the probe.The diagnosis of VVF was then clearly suggested by CEUS and confirmed by cystoscopy.The patient chose not to undergo treatment and was followed up continuously.This case suggests that CEUS can diagnose VVF more effectively and accurately,providing an important reference for the precise diagnosis of VVF.
