Duplicated collecting system
This week we will focus on congenital malformations of the genitourinary system. Such defects are common and can lead to recurrent infection, incontinence and other complications.
This is a case of duplicated collecting system, shown on intravenous pyelogram. Note complete duplication of the right collecting system and partial duplication on the left, with ureters joining at the level of L3. In complete duplication, the upper pole moiety tends to obstruct, while the lower pole moiety tends to reflux, placing patient at risk for infection. In this case, the left side shows eveidence of obstruction and/or reflux (VCUG or nuclear cystogram can be performed to demonstrate reflux).
