Laparoscopic partial nephrectomy with prior superselective embolisation as treatment for giant renal angiomyolipoma. / Nefrectomía parcial laparoscópica previa embolización supraselectiva como tratamiento de angiomiolipomas renales gigantes.

OBJECTIVE: Cases of giant renal angiomyolipoma (>9cm) are a therapeutic challenge due to their low frequency and large size. The treatment objective for patients with renal angiomyolipoma should be complete tumour extirpation, with a nephron-sparing surgical technique, without complications and using a minimally invasive approach. MATERIAL AND METHODS: We present 3 cases of giant angiomyolipoma (10 12 and 14cm) treated with a combined approach: superselective embolisation and subsequent laparoscopic partial nephrectomy, in 3 separate hospitals. RESULTS: None of the cases required conversion to open surgery. One of the 3 patients underwent arterial clamping, and none of the patients had complications. CONCLUSIONS: The combined approach provides a procedure with the criteria of minimal invasiveness, nephron sparing, little bleeding and reduced warm ischaemia time.
