[Transperitoneal laparoscopic enucleation of renal angiomyolipoma: a report of 10 cases].

Objective: To evaluate the feasibility and clinical effect of transperitoneal laparoscopic enucleation of renal angiomyolipoma (RAML) without obstruction of renal pedicle.

Methods: Ten patients with renal angioleiomyoma (tumor diameter < 4 cm) were operated by transperitoneal laparoscopy without obstruction of renal pedicle. The operating time, blood loss, hospital stay after operation, intraoperative and postoperative complications and the operative effect were observed.

Results: All the 10 patients underwent the operation successfully. The average operating time was 90 min, average blood loss was 80 ml, the average hospital stay after operation was 7 d. No intraoperative or postoperative complications occurred. Follow-up period was 3-19 months and no tumor metastasized or occurred again.

Conclusion: This mininvasive procedure is a more precise and complete method than before, which can minimize the blood loss and make patients recover quickly, so it is well worth clinical applying.
