The purpose was to evaluate the feasibility of diagnosing vesicovaginal fistulas by colour Doppler ultrasound with contrast media. Twelve consecutive patients were examined by vaginoscopy, methylene blue test, cystogram and cystoscopy. For ultrasound examination, the bladder was filled with saline. Then diluted contrast media (Levovist®) was instilled. Colour Doppler ultrasound revealed a jet phenomenon through the bladder wall toward the vagina, proving the existence of the fistula. Eleven patients had vesicovaginal fistulas, one patient a vesicoureterovaginal fistula. Colour Doppler ultrasound had correct results in 11 of 12 patients (92%). In follow-up examinations of four patients during a prolonged drainage of the bladder, we could correctly demonstrate the closure of one fistula. Colour Doppler ultrasound with contrast media is a new useful diagnostic tool in the evaluation and follow-up of vesicovaginal fistulas. It is less invasive than cystoscopy and needs no radiation exposure. The examination is well tolerated by the patients.
