[The elimination of extended defects of the ductus deferens]

Based on their own experience gained in 12 reconstructive surgeries performed for iatrogenic lesions of the deferent duct in 8 patients the authors came to the conclusion that in the majority of patients an immediate vasovasostomy would be a failure or incompetence because of a significant tension of the tissues. To solve the faced problem, the authors proposed a technique of extra-anatomical (supra- and subpubic) anastomosis which enabled one to reduce the length of the duct by 9-19 cm. Transplantation of the duct's segments in the rat failed to demonstrate any benefit in case of homotransplantation of the duct's segments whereas autotransplants survived in 70 per cent of the cases and provided a 40 per cent recovery of the duct's patency. No signs of endoprosthetic effect on the transplantation outcomes were evident.
