OBJECTIVES: To review our experience with ureteropelvic junction obstruction in a duplicated renal collecting system. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
