Renal sparing surgery using focus ultracision harmonic scalpel in patients with bilateral wilms' tumor: case report.

Background: Bilateral Wilms' tumor is rare and surgical treatment requires an individual approach. Surgical approach to the tumors located in the central part of the kidney represents a major challenge and nephrectomy is usually essential. Renal sparing surgery is difficult in such cases.

Case Report: We describe a 3 year-old female patient with bilateral Wilms' tumor arising in the central localisation of the right and foci in the left kidney enucleated successfully with a simple and comfortable renal preserving operative technique using Focus Ultracision Harmonic Scalpel.

Conclusion: In cases when tumors are located in the central part of the kidney and partial nephrectomy is consequently very difficult, the use of a Focus Ultracision Harmonic Scalpel provides easy dissecting, enucleation, and excision of the tumor.
