Tumeurs du rein et des voies excrétrices chez l'enfant

Diagnosis of renal tumours is built-up on clinical findings such as age, symptoms and US findings such as volume and spread of the tumour. The most commonly encountered, between 18 months and 5 years of age, is the Wilms’s tumour which may be associated with congenital abnormalities. Diagnosis of other kidney tumours may be difficult. The tumours of the urinary tract are rare, revealed by hematuria. The most common is rhabdomyosarcoma of the bladder. Diagnosis requires US examination, opacification of the collecting system and MRI.
