[Analysis of 10 years' data of systematic male reproductive system ultrasonography in diagnosis of azoospermia etiology].

OBJECTIVE

To explore the value of systematic male reproductive system ultrasonography in the diagnosis of azoospermia etiology.

METHODS

Retrospective analysis and classification statistics were conducted on the data of azoospermia cases who underwent systematic male reproductive system ultrasound examination at the First Affiliated Hospital of Ningbo University from January 2013 to January 2023.

RESULTS

A total of 375 cases were included in the group, of which 303 cases could be diagnosed by ultrasound, including 161 cases of obstructive causes, 110 cases of non obstructive causes, and 32 cases of mixed causes. Obstructive causes mainly include bilateral absence or underdevelopment of the seminal vesicles and vas deferens, non obstructive causes mainly include bilateral simple testicular dysplasia, and the most common combined causes are bilateral absence or underdevelopment of the seminal vesicles and vas deferens combined with bilateral testicular dysplasia. The main causes involved a single organ in 174 cases, with 82 cases, 43 cases, and 4 cases involving 2-4 organs, respectively. In addition, there are multiple accompanying ultrasound manifestations of non primary causes.

CONCLUSION

Systematic ultrasound examination can comprehensively evaluate the male reproductive system, effectively diagnose the causes of most azoospermia, and provide valuable imaging evidence for clinical treatment.
