[Experience with the application of microsurgical technique in the treatment of urological diseases].

Microsurgical techniques were carried out in reanastomosis of the vas deferens, autotransplantation and replantation of the testis, adrenal autotransplantation with attached blood vessels, anastomosis between the internal spermatic lymphatic vessel and vein, and internal spermatic venous diversion. Double-layer and single-layer anastomosis were adopted in vasovasostomy. It was observed that the former technique seemed a little better but the difference was not statistically significant in regard to the patency and pregnancy rate (P greater than 0.05). Testicular autotransplantations were carried out in two cases, each with bilateral cryptorchism and they were both adults at the time of operation. Postoperative follow-up turned out that spermatogenesis didn't happen. Replantation of a testis was applied to a case with complete traumatic severance of both funiculi within the scrotum. The patient regained his normal endocrine and spermatogenetic functions postoperatively. The techniques of adrenal autotransplantation with attached blood vessels and that of the anastomosis between lymphatic vessel and vein are discussed.
