| Popis: | Objective To determine the sensitivity and specificity of 640-Multislice CT (640-MSCT) in diagnosing the female UD. Materials and methods We investigated 16 patients with symptomatic UDs preoperatively in our hospital from August 2010 to March 2016. The patients’ average age was 38.8 years. All patients were performed 640-MSCT of pelvis; then, 3D and 4D images were reconstructed preoperatively. Results In 3D and 4D-CT images, out of 16 patients, thirteen patients had one ostium, two had 2 ostia and one had 3 ostia. Out of those thirteen patients, eight patients’ ostia were located at 5 o’clock and five patients’ at 7 o’clock. Patients with 2 ostia location were at 5 and 6 o’clock and 5 and 7 o’clock, respectively. Patients with 3 ostia location were at 5, 6 and 7 o’clock. The mean distance from the bladder neck to the ostia was 22.5 mm. The shape of UD was out-pouching in 11 patients (68.8%), U-shaped in four patients (25.0%) and circumferential in 1 patient (6.2%). The CT findings were confirmed by surgical findings. Conclusions 640-MSCT is a useful tool in identifying UD’s shape and ostium (including number, location) before operation. Preoperative 640-MSCT should be an adaptable modality for clinically suspected UD patients. Advances in knowledge Several imaging methods have been used to diagnose female UD. 640-MSCT may be more suitable to diagnose it for its higher sensitivity and specificity in diagnosis of female UD, especially in identifying UD’s shape and number and location of ostium. |
