Ureteropyeloscopy can be a crucial examination in case of diagnostic doubt. Choice therapy is nephroureterectomy with vesical collar resection when the tumour's anatomical state or the subtotal nephrectomy allow it. Prognosis of these tumours is very poor, mean survival of patients being of about 4 months. Our patient died one month after surgery.

Ureteric polyp is a benign lesion, and an uncommon cause of hydronephrosis in children.
It is associated with intermittent lumbar pain and haematuria. The diagnosis is usually based on intravenous urography or retrograde urography. Treatment must be conservative and consists of simple resection of the polyp, associated with varying degrees of ureteric resection depending on the size of the lesion. No case of recurrence after treatment has been reported to date. Cytological findings of voided urine suggested the presence of malignant cells.
