To review our experience with ureteropelvic junction obstruction in a duplicated renal collecting system.
The records of 7 patients with ureteropelvic junction obstruction in a duplex collecting system were reviewed. In addition to routine demographics, each case was reviewed for presenting symptoms, site of obstruction, and type of surgical treatment.
Three of the 7 cases involved obstruction of the upper pole moiety, and the remaining 4 involved the lower pole segment of a duplex system. Obstruction of the upper and lower pole segments was found in both incomplete and complete duplicated collecting systems.
Careful preoperative evaluation of patients with ureteropelvic junction obstruction will usually identify segmental obstruction in a duplicated system. Treatment should be individualized based on site of obstruction and degree of function remaining in the affected segment.
