The treatment of angiomyolipomas (AML) of the renal sinus is challenging and often requires nephrectomy. In this study, we report on 5 patients who underwent extracorporeal AML resection and subsequent renal autotransplantation (RA) for renal sinus AML.
As of May 2013, 5 patients had undergone extracorporeal AML resection and RA for renal sinus AML at our institute. Separation of the AML in renal sinus is performed by combined sharp and blunt dissection. Tissue between AML and renal sinus is ligated where blood vessels cannot be excluded. When complicated with AML of the renal parenchyma, the AMLs were resected using ultrasound guidance.
Renal nuclear scan showed that kidney grafts were perfused uniformly without evidence of segmental infarction at day 7 posttransplantation in all patients. No significant deterioration in renal function and tumor recurrence was noted over a median follow-up of 3 months (range: 1 to 6 months). All patients presented with normal blood pressure values. No intraoperative complications occurred.
Bench surgery and subsequent RA method, due to its advantage of kidney preservation, is a valuable option for renal sinus AML treatment.
