Abstract:
Objective To analyze the clinical and radiographic characterstics of ureteral polyps with hydronephrosis in children.Methods Thirteen patients with ureteral polyps and hydronephrosis were studied retrospectively.All patients underwent abdominal plain film,intravenous pyelogram(IVP)and ultrasound(US)examinations,contrast-enhanced CT scan was performed in 10 cases.Results Intermittent or recurrent abdominal pain with painless hematuria was presented in most cases.Hydronephrosis was demonstrated in radiographic images.IVP delineated the dilatation of the ureter and filling defects within the ureteral lumen in 5 cases.Computed tomography(CT)showed all abnormal changes of ureter and irregular intraluminal soft tissue masses in 6 cases.Moderate and low echoic structures were showed in ureters by US in 2 cases.Conclusion US and CT,as an important imaging modalities,can improve the diagnostic accuracy for ureteral polyps.
