선천성 정관형성부전증

Abstract

Seventeen patients with congenital agenesis of the vas deferens, 9 per cent of 188 azoospermias due to epididymal obstruction, were investigated in tbe department of urology for the past 16 years, These anomalies were confirmed by surgical explorations. All the patients were married for 4 years with range from 1 to 15 years. Age of patients ranged from 27 to 41 with the mean of 31 and that of their wives ranged from 23 to 34 with the mean of 28. Sexual coitus per week ranged from I to 6 with the mean of 2.5. They were consisted of 14 patients with bilateral agenesis of vas deferens and 3 patients with unilateral agenesis. Associated absence of epididymal body and/or tail was found in 52 per cent of a total of 31 anomalies of vas deferens. Spermatocele was not found in epididymal head. Tubular dilatation of the epididymis was seen in 6 out of the 31 epididymal head. The histologic examination of the testes showed normal spermatogenesis in the most of the cases. In two patients with unilateral agenesis of vas deferens, the obstructive lesions of epididymal tails of contralateral side were corrected by side to end anastomosis of epididymal head to vas deferens under surgical microscope. The result were successful in one patient of them. For the other patients, the implantation of alloplastic spermatocele should be considered. In conclusion, the results of this clinical investigation emphasizes the importance of careful scrotal examination in the diagnosis of an infertile male patient and In the preoperative check of vasectomy operation.
