Congenital vas deferens-ureteral connection

Congenital drainage of the vas deferens into a ureter permits retrograde passage of urine through the vas to the epididymis. If this anomaly is accompanied by urinary tract pathology with vesicoureteral reflux, hydroureter, stasis, and infection, the passage of urine into the vas can very well lead to epididymitis of a chronic or recurring nature and secondary scrotal abscesses. Two cases of this rare anomalous connection are presented in which such scrotal infections occurred. The diagnosis should be suspected on clinical grounds and can be confirmed by cystograms in which the dye refluxes up the ureter and passes into the vas. The association of rectal anomalies is of embryologic significance and may be additionally important clinically by further suggesting the possibility of the ureteral-vas anomaly.
