Abstract

Objective: To study the feasibility and the innocuity of the treatment by radiofrequency of small renal tumours., Material and Methods: From June 2000 to September 2001, 10 renal tumours in 6 patients were treated by radiofrequency. The mean age of the patients was 57 years. The mean tumour diameter was 20 mm. Indications for partial surgery were 3 solitary kidneys, one patient with chronic renal failure, one patient with Von Hippel Lindau disease and one patient in whom several angiomyolipomas were discovered in the right kidney. 4 patients were treated via a lumbar incision and 2 were treated percutaneously (one with ultrasound guidance and the other with computed tomography guidance). Patients were reviewed by imaging (CT and/or MRI) with injection of contrast agent to demonstrate complete devascularization of the tumour., Results: Treatment lasted an average of 180 minutes. The intraoperative complication rate was 16%. The mean hospital stay was 9 days (4 days for the percutaneous route). Nine tumours (5 patients) were devascularized after a single session. One patient (treated via the percutaneous route under ultrasound guidance) showed persistence of tumour tissue (identified by CT). A second session, performed 4 months later, allowed complete devascularization of the tumour. The mean follow-up is 13 months., Conclusion: This study demonstrates the feasibility and safety in terms of renal function of radiofrequency treatment of small renal tumours. However further studies are necessary to precisely define the radiological criteria of tumour necrosis and to evaluate the long-term results of this method (outcome of necrotic tumour tissue, metastatic risk, cancer recurrence along the needle track in the case of a percutaneous approach). This treatment must be reserved for selected patients.

29. [Psoas tumors].

Abstract

The authors report a case of benign tumor of the psoas muscle occurring in a 36-year-old man. The diagnosis was based on computed tomography and the patient underwent tumorectomy by an extrapoeritoneal approach. The authors emphasize the ratity f psoas tumors that are usually malignant and the advantage of computed tomography and percutaneous biopsy. Treatment must be incorporated into a multidisciplinary approach in which surgery plays a leading role and must be based on the treatment of soft tissue tumors.

Abstract

Retroperitoneal nerve sheath tumors (RNST), which include benign and malignant schwannomas and neurofibromas, are rare. A 71-year-old woman was complaining of flank pain. Ultrasonography and computed tomography revealed a retroperitoneal tumor measuring 22 x 15. It was successfully removed and extirpated through a midline laparotomy incision. It weighed 7 kgs. Histochemical and immunohistochemical staining of the tumor are useful for the diagnosis of solitary neurofibroma. After a two year follow-up, the patient is in good health, asymptomatic and without evidence of local recurrence.
