Abstract

Duplication of collecting system is one of the most common upper urinary tract anomalies, affecting around 15% of the population. In the duplicated system, kidney has two pyelocaliceal systems and it is associated with a single ureter or with a bifid ureter (partial duplication) or, in the case of a complete duplication, with two ureters (double ureters) that drain separately into the urinary bladder. In this last case, usually, ureters follow the “Weigert-Meyer Law” according to which, upper pole ureter drains medially and inferiorly compared to lower pole ureter that drains in bladder in orthotopic position, laterally and superiorly compared to the other one. Partial duplication can be associated with two problems: pelvi-ureteric junction obstruction and retrograde peristalsis of urine in the two ureters as “Yo-Yo phenomenon”. We describe a case of a 20 years-old woman who accessed to our department for right flank pain and fever. CT-scan showed incomplete duplication of right collecting system with hydronephrosis and thinned cortical of lower kidney moiety. Patient was successfully treated in conservative way.
