[Unique incision vasectomy: review of 1,800 cases]. / Vasectomía por única incisión: revisión de 1.800 casos.

We reviewed 1,800 vasectomy procedures using the double lateral scrotal incision and single incision of the raphe that had been performed at the Family Planning Center. The number of complications were minimal for both techniques: 6.5% for the patients submitted to the double incision and 5.5% for those submitted to the single incision procedure. The advantages of the single incision procedure are: it is easy to perform, less anesthesia is required, there are less complications, and the operating time is reduced.
