Localization of obstruction sites in obstructive azoospermia: role of combined transscrotal-transrectal ultrasonography.

ABSTRACT:

Objective

To evaluate the diagnostic performance of combined transscrotal-transrectal ultrasonography in predicting sites of obstructive azoospermia.

Materials and methods

From June 2019 to March 2023, 166 obstructive azoospermia patients who underwent surgical exploration were enrolled in the retrospective study. The data of combined transscrotal-transrectal ultrasonography in 166 patients were collected and analyzed. The receiver operating characteristic (ROC) curve analysis was employed to evaluate the diagnostic performance of these ultrasonographic measurements for localizing different obstructive sites.

Results

There were 9 sides of intratesticular obstruction, 239 sides of epididymal obstruction, 68 sides of vas deferens obstruction, and 16 sides of ejaculatory
