title: [Conventional or microsurgical op-technic in diagnostic deferens vesiculography?].
abstract: A catamnestic study revealed azoospermia in the spermiogram following one in three radiodiagnostic operations on vasa deferentes using conventional techniques, whereas this was not found in a single case following the use of microsurgical techniques. The authors agree with the literature that manipulation of the vas deferens with large surgical instruments is a significant cause of postoperative occlusion, which is to be seen as an avoidable complication when microsurgery is used. Criteria for the indication and contra-indication of deferento-vesiculography are recommended, which may help to lower the at present high rate of post-operative occlusion azoospermia.
