Coexisting pelviureteral and vesicoureteral junction obstruction in children.

OBJECTIVE: To address reasons for diagnostic failure in children with coexisting pelviureteral and vesicoureteral junction obstruction.

PATIENTS AND METHODS: A total of 11 children with coexisting pelviureteral and vesicoureteral junction obstruction are reported. This anomaly was recognised at presentation in only 5 (45%) of cases. In the remainder, correct diagnosis was made after initial pyeloplasty and a significant delay occurred in 3 children. In all 11 patients treatment consisted of pyeloplasty and subsequent reimplantation.

RESULTS: A satisfactory postoperative course with improvement of urinary tract dilatation was noted in all 11 patients, while 8 of 11 patients showed preserved renal function at late follow-up.

CONCLUSION: According to the few available data, our data confirm the difficulty of diagnosing coexisting pelviureteral and vesicoureteral junction obstruction in children. However, prompt recognition and relief of urinary obstruction in these patients is mandatory in order to prevent deterioration of renal function.
