[Renopyeloureteral duplications with extravesicular dilatation of the ureters (bilateral case and unilateral case)].

A review is made of the most outstanding, clinical facts in the U.P.R.D. with extravesical, ectopic, ureteral anastomosis, with special reference being made to the radiological diagnosis. The authors recall those stated in Weigert and Meyer's Law, as well as the deformities and deviations which may appear in the twin excretory systems as a result of their duplicity. They defend the subtotal heminephroureterectomy as the best means of therapy for correcting incontinence, providing that there is no ther concomitant anomaly or illness in the opposite kidney as well as in that of the duplicity itself. Two kinds of cases are presented: one bilateral with widening of the right, superior ureter in the urethra and the same on the left side in the vulva; the other left, unilateral with ectopia of the supernumerary ureter in the urethra.
