Abstract

Objective: We present our experience with 15 patients with renal angiomyolipoma warranting intervention. Methods: The medical records and radiological studies were reviewed for patient age and sex, tumor location and size, association with tuberous sclerosis, and treatment approach. All patients were regularly followed by ultrasound and computed tomography scan. Results: Presenting symptoms were retroperitoneal bleeding in 9 patients and flank pain in 6. Excluding cases of tuberous sclerosis (mean tumor diameter 11 cm), the mean diameter of the two tumors that bled was 5.4 cm, similar to those in the patients presenting with flank pain. Two patients with retroperitoneal bleeding had tumors < 3 cm. Angioinfarction was performed in 7 patients, partial nephrectomy in 3, and total nephrectomy in 4. One patient with tuberous sclerosis, who was observed only, died of bleeding and sepsis. The mean follow-up period of 4.3 years revealed stable creatinine levels and no recurrent hemorrhage. Conclusions: The management approach of angiomyolipoma should be aimed at parenchymal preservation which can be effectively accomplished by limited surgery or preferably by selective embolization. Preventive embolization may be feasible even for small tumors. However, any doubt about the diagnosis of angiomyolipoma should be clarified by surgery.
