Abstract OBJECTIVES: To report on the role of simple enucleation for treating renal angiomyolipoma (AML) in a series of patients treated in our department. PATIENTS AND METHODS: We retrospectively reviewed the data of all 37 patients with a histopathological diagnosis of renal AML who had either radical nephrectomy (three) or nephron-sparing surgery by simple enucleation (34) between January 1986 and December 2005. Indications for intervention included either symptomatic AML or a tumour of >4 cm, regardless to the presence of symptoms or renal masses suspicious of malignancy. The patients' status was evaluated last in October 2006. RESULTS: The mean (sd, median, range) pathological tumour size was 5.2 (3.4, 4.8, 1.5-15) cm; five patients (15%) were affected by tuberous sclerosis. Simple enucleation was successful in all patients but in three (9%) a sharp dissection a few millimetres from the tumour was used during critical steps of the procedure where it seemed difficult to define the right plane of enucleation. Warm ischaemia was used in 79% of patients, with a mean ischaemic time of 11.2 min. Two patients (6%) required renal hypothermia. A simple parenchymal compression was used in five cases (15%). The mean (range) intraoperative blood loss was 170 (70-650) mL. None of the patients had postoperative bleeding requiring re-intervention but one (3%) required two units of blood after surgery. There were no major complications, e.g. prolonged acute tubular necrosis/chronic renal insufficiency and urinary leakage/urinoma, but two patients had urosepsis not associated with perirenal fluid collection and that required targeted antibiotic therapy. At a mean (median, range) follow-up of 56 (50.5, 10-120) months none of the patients had local tumour recurrence. Two patients had a small AML elsewhere in the operated kidney, detected 18 and 36 months after surgery, with a kidney recurrence rate of 6%. CONCLUSIONS: Our data confirm the optimum results of simple enucleation for renal AMLs; this technique provides excellent long-term local control and no patient had urinary leakage/fistula afterward.

Abstract

Abstract OBJECTIVES: To report on the role of simple enucleation for treating renal angiomyolipoma (AML) in a series of patients treated in our department. PATIENTS AND METHODS: We retrospectively reviewed the data of all 37 patients with a histopathological diagnosis of renal AML who had either radical nephrectomy (three) or nephron-sparing surgery by simple enucleation (34) between January 1986 and December 2005. Indications for intervention included either symptomatic AML or a tumour of >4 cm, regardless to the presence of symptoms or renal masses suspicious of malignancy. The patients' status was evaluated last in October 2006. RESULTS: The mean (sd, median, range) pathological tumour size was 5.2 (3.4, 4.8, 1.5-15) cm; five patients (15%) were affected by tuberous sclerosis. Simple enucleation was successful in all patients but in three (9%) a sharp dissection a few millimetres from the tumour was used during critical steps of the procedure where it seemed difficult to define the right plane of enucleation. Warm ischaemia was used in 79% of patients, with a mean ischaemic time of 11.2 min. Two patients (6%) required renal hypothermia. A simple parenchymal compression was used in five cases (15%). The mean (range) intraoperative blood loss was 170 (70-650) mL. None of the patients had postoperative bleeding requiring re-intervention but one (3%) required two units of blood after surgery. There were no major complications, e.g. prolonged acute tubular necrosis/chronic renal insufficiency and urinary leakage/urinoma, but two patients had urosepsis not associated with perirenal fluid collection and that required targeted antibiotic therapy. At a mean (median, range) follow-up of 56 (50.5, 10-120) months none of the patients had local tumour recurrence.
