Ureteric jet examination by color Doppler ultrasound versus IVP for the assessment of ureteric patency following pelvic surgery--a pilot study.
During the study period 228 women underwent major gynecological surgery in our department. Of these, 25 were selected for the study because of suspected post-operative ureteric obstruction. Post-operatively, both intravenous pyelography (IVP) and ureteric jet examination by the means of color Doppler ultrasound were performed in the study group. The aims were to exclude iatrogenic ureteric occlusion and to test the reliability of ureteric jet examination with ultrasound, as compared with IVP, as a diagnostic test for ureteric obstruction. In 19 patients both IVP and jet examination were normal. In the remaining six patients, jet was negative either uni- or bi-laterally. Of these six, only two obstructions were diagnosed using IVP. This test was associated with a positive predictive value of 33.3%, negative predictive value of 100%, sensitivity of 100%, specificity of 88.6%, false negative of 0% and a false positive of 17.4%. It is concluded that the results suggest that color Doppler ultrasound may be a good screening test for ureteric occlusion following pelvic surgery. Whenever a jet test is negative, further evaluation by IVP is required.
