title: Wilms tumor and a duplex collecting system: a case report and review of literature.
abstract: Wilms tumor (WT) is described as a component of many different clinical conditions and genetic syndromes. However, the simultaneous occurrence of WT and a duplex collecting system is extremely rare. We report a case of a 4-year-old boy diagnosed with WT and a left duplex collecting system. The patient underwent a left radical nephrectomy. The histologic examination diagnosed it to be a case of WT with favorable histology. The patient received the chemotherapy regimen for stage 1 WT and was in complete remission during the follow-up period of 2 years. Further investigations are required for assessing the need for screening of WT in children with genitourinary malformations.
