Microsurgical vasoepididymostomy in the treatment of occlusive azoospermia.
OBJECTIVE
To evaluate the practice and outcome of the end-to-end and end-to-side techniques of vasoepididymostomy for the treatment of occlusive azoospermia.


METHODS
This retrospective study comprised 31 unselected patients (mean age 32 years, range 22-59) operated on with one of two techniques, more usually a modified end-to-side technique. Sperm quality and paternity were assessed in 24 patients during a 2-year follow-up.


RESULTS
Of the 15 patients in whom sperm were found at anastomosis, sperm were retrieved from 11. Of 24 patients, 11 had patent anastomoses and paternity was achieved in three cases.


CONCLUSIONS
Although performed by a proficient microsurgeon the operative success rate was low, partly because the operation was technically demanding but largely because of the difficulty in assessing intraoperatively the level of occlusion and the quality of the sperm. Better techniques for the evaluation of sperm during the operation should be developed.
