Ectopic vas deferens: a report of two cases and review of the literature

Abstract

Two new cases of ectopia of the urethral end of the vas are described, and six cases reported since 1949 are reviewed. Most cases had associated urinary tract abnormalities, often anomalies of renal position, and imperforate anus was the most frequent gastrointestinal anomaly. The most productive mode of radiologic evaluation was voiding cystourethrography. The two types of insertion and the associated urinary and gastrointestinal anomalies are analyzed on the basis of embryologic development.
