[Ambulatory vasectomy. Risks and complications].

Abstract

Vasectomy is the simplest and most effective method of permanent sterilization in men. In most cases, the surgical technique includes conventional vasoresection with incision of the scrotal skin or no-scalpel vasectomy as a minimally invasive method. The most important complications following surgery are haemorrhage and haematoma (1.2%), infection (3.5%), epididymitis/epididymo-orchitis (2.1%), sperm granuloma (2-70%), and chronic pain (3-8%). No long-term negative organic effects have been proven in clinical studies. The surgeon's experience and the technique applied are essential for the postoperative course, whereas performing vasectomy either on an in-patient or out-patient basis does not seem to have an influence. To evaluate the success of the vasectomy, follow-up spermiograms are obligatory. If immotile spermatozoa are present further follow-ups are necessary. Vasectomy needs to be reperformed if motile spermatozoa are detected. The chance of an unsuccessful vasectomy is below 1%. Unprotected intercourse must not be performed before two consecutive spermiograms show azoospermia.
