OBJECTIVE: To prospectively compare power Doppler ultrasound diagnostic performance with reference standard cystoscopy in evaluating ureteral patency in a population at high risk of ureteral lesions.
METHODS: We analyzed 100 women who underwent pelvic organ prolapse repair. All ultrasound scans were obtained, at the end of the procedures, before cystoscopic evaluation. Bilateral simultaneous ureteral jet evaluation with power Doppler was performed at the level of the ureterovesical junctions with a pulse repetition frequency set to detect low flow for a maximum of 3 min.
RESULTS: According to the reference standard urethrocystoscopy, at least one ureter not ejaculating was observed in 6% of patients, for a total of seven ureters jets not visualized. No false-negative results were obtained. Ultrasound with power Doppler showed 100% sensitivity and 95.9% specificity in detecting the lack of ureteral jet. The negative predictive value was 100%, and the positive predictive value was 46.7%.
CONCLUSIONS: Ultrasound with power Doppler represents an effective and reliable non-invasive screening test to exclude ureteral kinking and reduce the need for intraoperative cystoscopy.
