[Conservative management of renal haemangioma: value of a synergistic combination of flexible ureteroscopy and CT angiography]. / Traitement conservateur d'un hémangiome rénal: intérêt de la synergie urétéroscopie souple et artériotomodensitométrie.

ABSTRACT

Renal haemangioma (RH) is a rare congenital vascular lesion that is frequently responsible for macroscopic haematuria. This lesion is difficult to diagnose preoperatively despite progress in imaging techniques. These diagnostic difficulties account for the high rate of radical treatment (nephrectomy or nephro-ureterectomy) due to a suspicion of renal carcinoma or upper urinary tract tumour. However, conservative diagnostic and therapeutic management can be performed by a combination of CT angiography, flexible ureteroscopy and selective embolization.
