Postoperative color Doppler flow ultrasonographic assessment of ureteral patency in gynecologic oncology patients.

Our objective was to assess postoperative ureteral patency in gynecologic oncology patients with color Doppler flow ultrasonographic assessment of ureteral jets. Forty-five consecutive gynecologic oncology patients meeting inclusion criteria prospectively underwent postoperative transabdominal color Doppler flow ultrasonographic assessment of ureteral jets to establish patency; 48 consecutive women undergoing transabdominal ultrasonographic studies for benign gynecologic conditions served as a control group. Statistical analysis included two-tailed t-test, with P < 0.05 considered significant. Bilateral ureteral jets were successfully demonstrated by color Doppler flow ultrasonography in all study patients and control patients. The mean time required to visualize bilateral ureteral jets was significantly different between the study group and control group (mean, 5.8 min +/- 0.6 min versus 2.6 min +/- 0.2 min, respectively) (P < 0.05). We conclude that postoperative ureteral patency in gynecologic oncology patients can be easily demonstrated by transabdominal color Doppler flow ultrasonographic assessment of ureteric jets.
