Congenital absence of vas deferens with ipsilateral urinary anomalies

Abstract

Unilateral absence of vas deferens is frequently associated with ipsilateral anomalies of the urinary tract. If a vas deferens cannot be palpated prior to vasectomy for sterilization, it is believed that an intravenous pyelogram should be performed. If any ipsilateral anomaly is found in the latter, only unilateral vasectomy should be performed followed by repeated semen analyses. Only when there is a persistent finding of sperm after three to four months should wide exploration of the hemiscrotum be done in cases in which the vas could not be found.
