Evaluation of the role of reflux pattern in Color Doppler Ultrasound on spermogram improvement after varicocelectomy

PURPOSE

Many attempts are being made to find an association between varicocele characteristics and sperm parameters. In this study, we investigated the association between a newly introduced varicocele reflux grading pattern and sperm parameters, as well as its effect on spermogram improvement after varicocelectomy.

METHODS

In a prospective study, 73 patients with a clinical single-sided varicocele who underwent corrective varicocelectomy were included. Reflux pattern was determined on Color Doppler Ultrasound (CDUS) and categorized into four grades: grade 1 (retrograde), grade 2 (augmentation), grade 3 (enhancement), and grade 4 (stasis). The association of pre- and postoperative spermogram with the patients' reflux pattern was evaluated.

RESULTS

A significant positive association was found between the venous diameter and reflux pattern. Higher grades of the reflux pattern were associated with the more severe hemodynamic pattern of the reflux (shunt type). A significant association was found between the reflux pattern and preoperative semen characteristics, and this association was more prominent in constant venous diameter. In this respect, the enhancing reflux type was associated with the most impaired preoperative sperm count, motility, and morphology. The enhancing type also revealed the most improvement in spermogram after varicocelectomy.

CONCLUSION

Patients with a higher reflex grade, particularly enhancing pattern, will most benefit from the surgical correction of varicocele. These findings suggest reflux pattern as a promising prognostic factor for a favorable outcome after varicocelectomy.

Evaluation of Judet view radiographs accuracy in classification of acetabular fractures compared with three-dimensional computerized tomographic scan: a retrospective study

Background

In the current diagnostic procedure, generally, both plain radiographs and 3D-CT scans are used for the diagnosis of acetabular fractures. There is no consensus regarding the value of a three-dimensional computerized tomographic (3D-CT) scan alone in the classification of acetabular fractures. In this study, we compared the accuracy of 3D-CT scan and plain radiography through the evaluation of their agreement with the intraoperative surgeon’s classification.

Method

In a retrospective study, patients who were referred to our center with an acetabular fracture and underwent surgical treatment were included. The classification of acetabular fractures was performed once using Judet view plain radiographs and once using a 3D-CT scan by the corresponding one Experienced musculoskeletal radiologist one independent trauma fellowship-trained orthopaedic who routinely treat acetabular fractures and based on Letournel and Judet classification (17 and 23 years of experience respectively). Cohen’s kappa value was used for the assessment agreement between the two imaging modalities, as well as between the imaging modalities and intraoperative classification.

Results

Medical files of 152 patients with acetabular fracture were retrospectively reviewed. A kappa value of 0.236 was obtained as the agreement level between radiographs and intraoperative findings (p < 0.001). A kappa value of 0.943 was obtained as the agreement level between 3D-CT and intraoperative classification (p < 0.001). An agreement level of 0.264 was found between the Judet radiographs and 3D-CT scans (p < 0.001).

Conclusions

3D-CT scans are reliable enough in the classification of acetabular fractures, and plain radiographs could be omitted to avoid radiation exposure as well as to reduce the cost for patients who sustain acetabular fractures.
