Laser-supported partial nephrectomy for renal cell carcinoma

Abstract

Objectives: The extirpation of peripherally seated renal tumors by partial nephrectomy is an established method. To decrease the disadvantages of vascular hilar clamping, we proved the use of a laser for partial nephrectomy. To date, this laser application has only been described in the animal model.

Methods: With an exophytic position of the renal tumor, we successfully performed nephron-sparing surgery without clamping of the renal vessels in 5 patients.

Results: Regular ultrasound monitoring showed no evidence of postoperative hemorrhage. The serum creatinine, hemoglobin, and hematocrit were nearly unaltered before and after surgery.

Conclusions: The results of our study have shown that laser-supported partial nephrectomy without clamping of the renal vessels, particular in carefully selected patients, is a safe alternative to classic partial nephrectomy.
