Sixty cases of congenital vas agenesis / 대한비뇨기과학회지

ABSTRACT

Out of 334 patients with obstructive azoospermia between Sep. 1983 and Aug. 1991. scrotal exploration for attempted epididymo-vasostomy showed vas agenesis in 60 of them(17.9%). The anatomical findings were classified into various groups of frequency. In the study of associated structural anomaly of seminal vesicle with transrectal ultrasonography, high incidence of anomalies was detected(8 out of 10). In bilateral vas agenesis, artificial insemination donor and artificial spermatocele were recommended for most of the patients and recently sperm aspiration from the epididymis was tried to unilateral agenesis, epididymo-vasostomies were carried out to ipsilateral (11) and contralateral(3) side. It is desirable to apply various operations with positive attitude. Further study including transrectal ultrasonography is expected to elucidate combined seminal vesicle anomalies.
