Case report: transcatheter renal embolization to effect renal ablation in recurrent PUJ obstruction in a patient with haemophilia.

We present a case of embolic ablation of a kidney with recurrent infected hydronephrosis in a patient for whom surgical resection was considered undesirable. The hydronephrosis recurred after embolization using gelfoam/steel coils but after a second embolization using lipiodol/absolute alcohol (50/50), the patient has remained asymptomatic. More than one embolization procedure may be necessary to effect renal ablation. Careful evaluation is necessary to determine whether ablation has been achieved. We recommend lipiodol/absolute alcohol as the embolic agent of choice.
